No sound mp4-playback

I bought my Eee Pad this friday, and I've been trying to get some 720p playback. It seems from searches that .mkv 720p playback isn't possible, so I tried some .mp4 720p files instead. Picture's running great, but when running HW decoding I get no sound - I have tried a bunch of players, I think almost everyone in the market. I've searched the forum, but can't seem to find any solution that works.
Dice Player, YX Player, MoboPlayer, Rockplayer - neither of them does the job.
I find it frustrating, since video playback is one of the main reasons I bought this device.

Check the sound settings of the .mkv and .mp4 files. The transformer doesn't do 5.1 digital. If your files are that type, there are quick programs that can recode just the sound, and leave the video the same(quick, as in 10-20 minutes).

Says it's 6-channel sound, so that must be the problem - which programs should I be looking into?

Also try MX Player...

I did actually try MX Player too - I've tried so many players that I don't remember names on all of them.

I have faced the problem with many files, MX Player usually works if I switch to SW decode. Look for the HW icon on top right, this is a toggle if you press it will switch to SW decode and you should get audio.

Yes, correct - MX Player does give me sound in SW decode, but it also gives me laggy video and sound isn't synced properly.

I just did a conversion using AVIdemux 2.5, to reencode the sound to stereo - plays as supposed to now, sound and smooth image. Took somewhat 20 minutes to reencode a 2½ hour movie.

I have been having the same problems as well iam hoping that they fix it soon

Playing avi didn't work

Hello,
i want to use MX Player to watch a avi-file at my Samsung Galaxy S3 (i9300). After starting the video, I only see the picture of the beginning and hear the sound (HD-Decoder).
After changing to SW-Decoder (there is a message abourt adpcm) I can see the movie, but there's no sound.
I also tried the Codec for ARMv7, but this did't solve the problem.
Information about the avi:
Video-Codec: Motion JPEG Video (MJPG)
Audio-Codec: IMA WAV ADPCM Audio (ms)

We couldn't reproduce the issue. Can you collect the bug report immediately after reproducing the issue and share here?
If you are not sure about how to collect a bug report, Kindly read https://forum.xda-developers.com/apps/mx-player/guide-how-to-collect-logcat-report-bug-t2843144

here is the bug report.

I have the same issue using the pro version, but it works on the starndard version. It was working on pro a few weeks ago.

The log contains only information about the HW decoder playback.
Basically, HW decoder uses the mediaplayer API provided by the Android. MX Player has fewer controls over it. So, MJPEG decoder may not be properly implemented in your custom ROM.
Can you share the logs again after playing it in SW?
It will be better if you can share a sample content as well.

report after playing it in SW

any ideas?

our developers are looking into the issue. we will try to fix the issue as soon as possible.
HW decoder issue might be from your ROM itself. So, it can be fixed from our end. Kindly cross check with your stock video player. It may behave in a similar way.

Skip forward/backward function acts weird on my device.

I have a 2015 model of sony bravia android tv, and it has a MT5890 CPU and a mali T-624 GPU. I installed the latest version of mx player and armv7 neon codec.
I am able to play x265 coded videos with built-in video player without any problem, it's very smooth, and I can skip forward or backward or just jump to whenever I wish to.
However when using mx player, it's also very smooth, but I can only play from the beginning, if I try to skip forward or backward, or jump to a certain time point, it starts to act very weird. Sometimes video speeds up 2x or 3x, sometimes it slows down, like it's catching up or slowing down to wait audio to be synchronized. And it can take from couple of minutes to half an hour to go back to normal.
This only applies to x265 coded videos, I have other video that are coded with x264 or HEVC, and they work just fine in both built-in player and mx player.
I have tried other video players like spmc, kodi or VLC, they all stutter, VLC is probably the best among these but it is still dropping frames left and right. But most of them don't have problem with skipping or jumping.
Can someone please explain the reason? Could it be fixed?
Much appreciated!

Basically, x265 is an encoder for HEVC. So, both are same.
Maybe some particular HEVC profile has issues. Can you try HW+ decoder?

In fact I am using HW+ decoder, and it's the only way I can play those videos smoothly. Switching to HW or SW would make the video either completely unplayable or stutter very heavily.
To sum it up, I CAN play any videos with built-in player smoothly and drag or jump or skip however I want to.
I CAN play x265 coded files smoothly with mx player in HW+ mode, but I CANNOT jump or skip. I CAN play any other videos with mx player without any problem.
I CAN play x265 coded files with some level of stutter with other players like spmc and VLC, but I CAN drag or jump however I want to.
The videos that I am having problem with have these kind of parameters:
Format : HEVC
Format Info : High Efficiency Video Coding
Format profile : Main [email protected]@High
Codec ID : V_MPEGH/ISO/HEVC
Writing library : x265 2.5+4-b4a5bcfe29c7:[Windows][GCC 4.9.3][64 bit] 10bit
If the writing library is x264 or ATEME Titan KFE or ATEME Titan file, or if the codec ID is hev1, or if the format profile is Main [email protected]@Main, I don't have a problem.
This is so weird....

To the TC - Did you ever get this sorted?
I am having the same issue on my Sony Bravia. Whilst the actual player is exactly what I wanted, I get exactly the same issue when fast forwarding or rewinding.
I have played around with the different codec settings but it doesn't seem to make any differences.
Did you end up finding a solution?
Cheers

Glad to see that I am not alone. But unfortunately I did not find any solution and had given up on this.
After all, it is only a tiny fraction of all the videos have this kind of behavior.

Thank you for the confirmation

Zoom video to fiil screen not working on HW/HW+ mode, Android TV

Hi everyone! I'm having a problem when I try to zoom in any video to fill the screen and eliminate the black bars on movies for example. I'm only getting a stretched video, not being able to get a proper uniform zoom, except when I select the software decoder. The problem is that some 4K videos can't be played smoothly on SW mode and also I lose the audio passthrough. I know this was once mentioned possibly as a hardware limitation, am I right?? I'm using the app on a TV with Android TV 6. The reported hardware SoC is a MediaTek MT5891 (Mali T-860 GPU). Any help would be much appreciated! Thanks!

C'mon guys, at least tell me there's nothing you can do about it!

Yes, It looks like a hardware feature of the TV Boxes. MX Just uses android APIs. It doesn't work properly once any one of the sides reaches the screen limit & starts stretching when you zoom more. In our internal tests, Mi Box used to have similar issues. But, there are no such issues after Oreo update Zoom works properly on all three decoders.

Thanks man! I've got a pending update from Android TV 6 to 7 so, maybe it'll work with it.

Hi everyone.
This may be a solution.
I get to realise that this thread has a long history and there is no proper answer.
I too had the same problem while using MX player in Android tv. But some video are able to crop view. After many thoughts I get to realise that there are two kind of popular encoding in mkv format.
Videos encoded in H.264 have no problem. But if it is H.265 commonly known as HEVC it will no crop or zoom in.
I currently use H.264 video for maximum use of my tv screen.
Please Google these encoding method for better understanding. There are some interesting comparison between two.
Happy watching

MX Player not all dialogue is Displayed

Just started using MX Player and like it very much.
I have movies recorded from TV and they have subtitles included in the file.
For most movies MX Player displays all the dialogue as subtitles very well.
I have some that when played with MX PLayer not all the lines of dialogue get displayed on screen.
I had this same problem with these movies when I first started using Potplayer on my windows PC.
Potplayer was able to fix this problem in one day and now all these movies display the subtitles perfectly using Potplayer.
I want to use MX Player on my android devices so would love to have the technical people try to modify the software to fix this problem.
I can supply a dropbox link to a very small portion of one of these movies where the problem occurs .
But not sure if that is OK to place here ?
If it is OK please let me know and I will include the link.
Please help.
