[Bug Report] No Audio on H/W Decoder ( Even with S/W audio )

Hi KTSamy,
I installed latest player and ARMv7 NEON codecs as it was advised by the player. However, it still not works properly.
I use a file manager capable to connect to my SMB shares and I initiate the playback from there. I tried to use HW+ decoder but I got a message stating that it is not supported. Using the recommended settings for HW decoder (software audio) I am still missing the sound. It worth to notice that audio channel selection contains 6 entries with some strange characters in them when in reality there are only two audio channels. As I found, others maybe some built-in subtitles, but there is nothing to do for them among audio channels. In this situation playback of a HD video is smooth enough, but there is no sound.
Switching to S/W decoder during playback solves problems with sound, and audio channel list shows the correct number and names of really existing audio channels. But in this mode even a SD video is painfully lagging. Impossible to see... If i switch back to HW decoder than sound remains and audio channel selection is also OK if the software audio decoding is selected. But the video still lagging. Not so much as in case of S/W decoding, but all my HD videos are rendered useless by that. Disabling sound in audio channel selection improves much the video playback, but again, without sound.
I think that the PAD2411 is a quite powerful device at least it should cope with HD video playback. Unfortunately it has numerous compatibility issues with almost all other video players due to the absence of its' own display. (Playback must go directly to the HDMI output.) MX Player is my unbeatable favorite and I use it on all my other devices without any problem. Do you have any idea how could I optimize the playback? Maybe the codec or the app should be adapted?
Thansk in advance!

Regarding audio issue on H/W decoder with S/W audio, Kindly collect the log immediately after playing the video & Upload here.
Regarding S/W issue, Your processor (Cortex A9 Dual Core) is a very old processor & not a powerful one. So, it can't handle many videos smoothly.
Note:
Kindly create a separate threads for your issues.
General issues are not to be reported on Custom Codec thread

I was busy with my work. So, I was not much active in XDA from the last few weeks.
Actually, In network playback MX Player won't use software audio with H/W decoder to avoid authentication issue.
If you H/W+ is working on your device, you can use it as alternative.
If you still wish to use H/W decoder, if Switch to H/W+ & Revert Back to H/W decoder it will bring the audio back.
According to the information provided by the developer, MXPlayer major upgrade v1.8 will resolve network authentication issues.

[Bug Report] No subtitles when streaming over LAN

I use ES file explorer to access folders on my NAS and PC, and previously this has worked perfectly for MX player playback.
In a recent update in the last few months, subtitle support was broken while doing this.
If i copy the file locally to the player, the subtitle menu appears and works fine - but running it over the SMB share, it behaves as if the file has no subtitles present.
This bug is present on all my devices, so its not a localised glitch - definitely happened as a result of an MX player update.

@bleu8888 did something change regarding SMB predictive requests for external subs in one of the updates?

I have an update for this.
Enabling hw+ decoding makes the subtitle button appear and it remains even if I change back to hw or sw.
The reason I hasn't noticed this before is that hw+ doesn't work on many of my videos due to them being 10 bit h264 (hi10p), so I had hw+ disabled in settings.

If my terrible accent can be ignored, heres a very brief video demonstrating the problem.
www.youtube.com/watch?v=O1lihO1-Zsc&list=UUgbORRfPfCYQb8wRW1plCUg
This workaround is far from perfect, as various videos will crash MX player if i try and force them to use HW+
If copied to the internal SD card, the subtitle icon appears without needing HW+.

Curious now, what is the naming format of the video and sub files?

.MKV with internal subtitles. That example video above has the following stats as read from MPC-HC on my PC.
Video: MPEG4 Video (H264) 1280x720 23.81fps [V: h264 high L4.0, yuv420p, 1280x720 [default,forced]]
Audio: AAC 44100Hz stereo [A: aac, 44100 Hz, stereo [default,forced]]
Subtitle: Advanced SubStation Alpha [S: ass [default,forced]]
Subtitle: UTF-8 [S: No subtitles]
An oddity has shown up with some files where subtitles appear, but i cant turn them OFF without doing this trick. Only happens over SMB shares, never happens locally with the same files.

... based on your original problem question, I thought you had external subs. Now that it's internal subs... I have no idea why, except perhaps that on HW, the android internal mediacodec broke something regarding embedded .ssa subtitles (that's only a guess). Unless this also coincided with a ROM update on xKat, I'm not sure that anything on MX specifically changed. It'll have to be @bleu8888 that would look into this.

not related to Xkat, the video showed this on my kogan HDMI dongle device, running its stock ICS 4.0 rom. Definitely internal subs, only over SMB.
Changing to software decoding also seems to bring the subtitle option back, although at first i didn't think that was the case.

Well, I don't think I can add any more value, so I'll just let the dev work on this

Same problem here: MKV file with embedded subtitles. Running Finless Bobs ROM 2.1 on an MK808.
When I play the file from a local directory, no problem, all subtitles are shown independent of HW or HW+ mode. When I try to play the SAME file from my NAS drive (accessing it with ES file explorer), the embedded subtitles do not show up, as if they were not existing.
The HW+ workaround above does work, but is not a satisfactory solution: Switching to HW+ does make the subtitles appear and selectable, video plays but stutters. You can then switch back to HW with the subtitles on, video plays smooth but freezes after ~5 seconds. So no working solution for NAS.
Hope this helps to reproduce the issue - please fix it!

try software mode, it also seems to bring them back. Often i change to software, enable subs, then change back to hardware and it remains working - as long as i use software audio, or the audio goes out of sync.

Tried SW mode, but same behavior: Video gets stuck when switching back to HW mode with subtitles on after about 15 seconds. Then turning off subtitles in HW mode makes video continue smooth.
So switching to HW+ or SW mode makes the subtitles appear and stay even when switching back to HW mode, but video gets stuck in HW mode with subtitles on. Issue only via LAN, HW mode works fine with subtitles when the file is local. I also don´t think it´s a bandwidth issue to my NAS, as the video plays fine via LAN without subtitles.

I'd say our slight differences there would be because we're using different hardware. Hopefully this bug gets some attention, i feel that using network shares isn't as popular as other methods so its a low priority fix.

That may well be. It´s a pity this issue doesn´t get a higher priority as playing videos from a NAS should become increasingly popular. It´s so convenient to have a big NAS drive to store all your music and video on and have it available for all devices in your network...

It depends on the SMB client that is used to stream. The behaviour changes from app to app. Some apps are acting as content providers. In that case, Player can access only the video files. Some apps act as a local host (like Solid Explorer). In such cases, MX might be able to detect the subtitles when either it allows the file listing or by a simple brute force check.

It seems that you are having some difficulties with our app. Unfortunately, we couldn't get your feedback well. Can you please contact us at [email protected] along with detailed steps to reproduce the issue or a screen record? It will help us to assist you better.

having the same issue, when streaming on lan it doesnt load the srt file loaded on the same folder, with the same file name, it used to work for quite some time, but now it no longer works, used es file explorer to browse through the NAS.
but if the folder is saved locally, the player can read it, using the es file explorer to access it as well.

[Q] Video never starts playing

I just purchased MX Player Pro from the Google Play store and have v1.7.40 (neon)installed on my Nexus 6. Since I have a lot of video files with AC3 audio, I installed the custom AC3 codec found here on XDA (automatic restart applied). After that, I configured MX Player Pro to use HW+ decoding and failover to HW decoding.
I can't seem to get videos to play at all. I open a video and it sits there like it's on pause. I've tried multiple video files and get the same result. Most are x.264, one is x.265. I've tried changing it to HW decoding as well as SW decoding but get the same result. I've force stopped the app and tried again after clearing the app data and telling it NOT to use the custom codec but still get the same result. Am I doing something wrong? I really like MX Player Pro but I'm going to need to refund it if I can't get it to work.
EDIT: On some videos that I start, if I manually fast forward, I don't see any video at all. On the x.265 video, I can manually fast forward and see the video frame of where it's at in the timeline but it just never plays.
END EDIT
On a side note, after launching MX Player Pro for the first time, I was not prompted to install the codec package so I installed it manually.
Thanks so much to anyone who takes the time to read this and/or assist with this matter.

Well, assuming by "codec package" you mean the ARMv7 Codec package on the Play Store, you don't need these codec packages by default. On the contrary, the fact that you installed the custom codec may be what's causing the playback issue.
The Custom Codec on XDA here is purely for AC3 and DTS audio compatibility, and generally shouldn't affect video playback.
To be certain, are you using the stock Nexus 6 ROM? If yes then which build in particular?
Also, if you could collect an error log after it freezes, that would help.
How-to MX Log Collector - Error Logs

@phoney_stuff
H/W+ may cause issues with certain videos. I don't recommend it to use it as default.
Just try to start the video in S/W decoder (log press the video & from menu > play using > SW decoder.)
Don't resume if it asks.
Let me know the results.
If you still have issues, kindly collect the logs immediately after playing the video & upload here.
@CDB-Man
As you know Custom codec is same as the inbuilt ffmpeg which comes with mx player itself. But, ac3 & dts support is enabled. So, it may not be the issue.
Both H/W+ & S/W decoders use ffmpeg. If the issue is there in S/W it might be an issue related to ffmpeg itself.

Gentlemen,
Thanks for the reply!
I'm running stock Android 5.1.1 on a non-rooted device, latest version, screenshot attached.
My first attempt was without the codec that's is available on the Play store, but with the custom AC3 codec. When that failed, I installed the codec from the Play store and got the same result. Then I tried it again after removing the custom AC3 codec (leaving the codec available from the Play store in place) and, again, got the same result. In a past experience of playing videos in MX Player with AC3 audio without the custom codec, the video would play without audio which is what I was hoping to achieve as a troubleshooting step (to see if the custom codec was causing a problem).
Currently, I have MX Player Pro installed with the codec that is available on the Play store as well as the custom codec to play AC3 audio. This is the config which we're basing our tests on as of now. Please let me know if I should remove the codec that I downloaded from the Play store. Also, I deleted the x.265 video that I mentioned in my previous post and obtained another video encoded in x.264. Regardless of this, it's important to note that I get the same result with ANY video I attempt to play. I'm attaching my loss for your review as requested. In this test, I have HW+ fully disabled in settings and SW decoding fully enabled. I also choose to start the video from the beginning rather than resume. Again, thanks so much for the help. Please let me know if there is anything else I can provide to help troubleshoot this issue.

@phoney_stuff
The issue is not with MX Player.
MX Player is not getting audio focus.
Looks like some other app is trying to keep the audio focus. That's why mx player is not playing any video.
Goto Settings > Player & Disable "Play Alone"
Then try again.
Note:
If you disable the option "Play Alone" MX Player will keeps on playing the video regardless of the status. For e.g it won't pause if you receive a call. So, best solution is that find the app that is stealing the audio focus & uninstall it or if there is any particular Settings in that app kindly adjust it.

@ktsamy
That did the trick, or it could be that I'm not currently using the phone that did the trick.... or both. VIC works while I'm on the phone so I guess I was expecting MX Player to do the same.
I'm going to leave Play Alone disabled since I like the option of playing audio our video when I'm on the phone.
Would it be too much for me to request an feature (toggle-able) to have MX Player to pause when it loses audio focus?

As in, using your version shouldn't in and of itself cause playback issues! As in, the issue is likely not caused by the fact that you are using the custom codec, but probably something else!

Enabling "Play Alone" does precisely just that? As in, make MX stop playing when it loses audio focus if another app plays...

@CDB-Man enabling Play Alone also prevents it from playing when it doesn't have a audio focus to begin with.

This is what the issue is.
Just find out the app that steals/keeps audio focus. Disable it or uninstall it.
You can now play even when "Play Alone" is enabled.
This is used to pause MXPlayer when you loose audio focus (like call or notification or alarm or Playback from another player). That's why it's enabled by default.
It's not the fault of MX Player.

Thanks be to you, I found the app that's keeping audio focus is the phone. I like the feature of Play Alone that pauses MX Player when it loses audio focus. However, I it would also be nice if MX Player allowed me to play audio our video) while I'm currently in a call without having to toggle Play Alone on/off all of the time.

[Q] MX Player Network Stream

Hello,
I hope someone knows a solution for the following.
I am using MX player on my NVIDIA Shield TV.
And I mainly use MX player to play video files that are stored on my network disk.
I am required to use the HW+ mode to get Dolby Atmos audio working.
This is all working fine, the only thing that is not working is fast forwarding and rewinding.
When I am using the same file on a USB stick it works fine, so it seems to be a issue when playing the files with the HW+ decoder over the network.
Does someone know a solution for this ?
I already installed the customer codecs btw.
Thanks in advance !

http://forum.xda-developers.com/showpost.php?p=51915844&postcount=1
Network playback buffering in general is a known issue, not specific to any of the playback methods. The developer aims to fix it in version 1.8 whenever that's ready.

Sorry for the late reply, I was very busy with some family matters.
I made one mistake in my first post, I was using the normal HW decoder.
The HW+ decoder does fast forward and rewind, but does not give me the dolby Atmos sound I described earlier.
I don't know if this changes the situation or answer ?
I will reproduce the issue and upload the logs when I'm back home from work.
Thanks for all the help !
PS. I already tried the alpha version (1.8.0) of MX Player, but the issue persisted.

HW uses android's native mediaplayer api.
Seems that your system doesn't have native dolby decoders. But, your audio system supports dolby decoding. In HW decoder audio might be passed to audio system. But, in H/W+ it will use system decoders to decode. So, if your device doesn't support that codec, it will use ffmpeg to decode (i.e, SW audio). If you use cutom codec you will get stereo output. Else you won't get any audio.
Only solution is to get audio pass through feature. It's expected in further minor updates to 1.8. (i.e 1.8.x).

Thanks, that is a very good explanation !
I did not really understand the difference between the 3 different decoders, but now I do, so thank you very much for that !
I noticed when I use the native video player on my Shield TV it does play Dolby atmos, but it has the same issue with rewinding/fast forwarding.
So because HW on MX Player uses the native media player API the buffering is not working ?
I suppose I just have to wait till audio passthrough is available in 1.8.
Or buffering will be available in the native media player.

Can screen size change the way a video file is played or handled?

Today my new TV arrived, I bought the xh90 to get myself ready for the upcoming gaming consoles, although the quality of the TV looks great, when I tried playing some files off my hard drive through the nvidia shield TV pro, 1 particular season always chops/screen freezes after a while, (this has only happend with this one series, all of the seasons are choppy) Everything else seems to play fine for now, also when I play the file through VLC everything seems to run smoothly, while with MX media player it does not.
The real kicker is on my previous TV the file is not choppy at all, neither with MX media player or VLC, the only difference seems to be my new TV is slightly bigger, 55 inch compared to my 41 inch previously. Does it perhaps have to do with the way MX media player encodes the file depending on what screen size you have?

We would like to let you know that MX Player's HW/HW+ decoders make use of the hardware acceleration provided by your device. So, the performance will heavily rely on the multimedia capabilities of your device.
Regarding your issues, could you please specify the decoder used? MX Player's HW decoder directly use the android mediaplayer framework. In case if you noticed glitches with HW decoder, it might be caused by a firmware bug. Please click/tap on the HW button on the playback screen and try HW+ decoder. It may fix the issue.

Switching to HW+ fixed the problem for me, around 90% of my files are able to play through HW+ now, the rest I have to switch back and forth between mostly SW and sometimes HW.
I'm glad there is an option as well to "always play files through HW+ decoder", otherwise I would have to re-select the encoder every time I would want to play a file from HW to HW+.
You're the only person who replied and I'm grateful since that was enough to help me resolve the issue.
