Can you share the sample clip?
We will test is in our MiBOX?
What's the version of the MX Box? What's the android version?
Can you provide more information about the important settings like screen resolution, refresh rate, other display settings?

MxPlayer latest version, my tv output is 1080p 60hz, I tested with latest marshmallow version , and recently upgraded to latest nougat (august), both version have the same problem.
It's a stream , i can provide you a link to the stream in private if you want (it's in my internal network, not so good upload but you can see for yourself)
Another problem that same stream have, when using HW codec, you cant reliably change audio stream. (if not for that, HW will be perfect)
Got this info from the stream when using MPC-Home Cinema:
"
Video: MPEG4 Video (H264) 1920x1080 29.97fps [V: h264 high L4.0, yuv420p, 1920x1080]
Audio: Dolby AC3 48000Hz 6ch 384kbps [A: English [eng] (ac3, 48000 Hz, 5.1, 384 kb/s)]
Audio: Dolby AC3 48000Hz stereo 192kbps [A: dub [dub] (ac3, 48000 Hz, stereo, 192 kb/s)]

It is because Galaxy S can't playback audio with 6 channels , i did not try this my self but that is what others observed.
Yes, I think it's limited to 5.1 channel audio encoded videos.
Also, that 4608kbps audio rate is awfully high.
Try using rockplayer and see if it works.
Was having a hard time w a video, wouldn't work in act1 nor the stock video player, worked great on rockplayer
Free on android market
Keep in mind Rockplayer is purely software player , it will not take advantage of phones Hardware acceleration , it will not play high resolution with good bitrate without dropping frames like crazy.
It would be better just to recode audio track.
I was just curious, because this was the same file that I had on my SD card that was in my BB Bold, which was able to play it???
[Bug Report] MicroDVD subtitles don't work on MKV videos after in version >= 1.7.33
After updating to version 1.7.33 or 1.7.34 the MicroDVD subtitles on MKV videos aren't showing.
SRT subtitles wok well, MP4 videos with MicroDVD subtitles work well too.
Example video file:
Video stream:
Sub type: H.264/MPEG-4 AVC
FourCC: AVC1 (H.264/MPEG-4)
Bit planes: 12
Dimensions: 1280x720
AvgTimePerFrame: 417083
FPS: 23,98
Audio stream:
Major type: Audio
Sub type: DOLBY_AC3
Channels: 6
Audio tag: 0x2000 (Dolby AC3 / FAST Multimedia AG DVM)
Frequence: 48000 Hz
Bitrate: 1536000
Are you getting sound? Did you install any custom codec?
It depends on the device. On my TV Dongle (Rikomagic MK802IIIS8G(B) - RK3066 procerssor) I have sound but MicroDVD subtitles don't work.
On my phone (HTC One S Z520e - MSM8260A procerssor) I don't have sound in H/W mode,
must use S/W audio (custom codec v7 NEON 1.7.32) but the MicroDVD subtitles don't work either...
Does the subtitle file have the same name and is in the same folder with the video you are trying to play?
Yes, it is... I've reverted back to 1.7.32 and everything works ok. On 1.7.33 and 1.7.34 it doesn't.
I've noticed that when I jump a few minutes forward on the movie a random subtitle is shown, but it doesn't change for correct one.
One important thing. I'm streaming this videos from Windows share on my computer.
I'm doing this with ES File Explorer using Samba protocol. Nevertheless the SRT subtitles work well in this config...
Did you check settings>subtitles>enable subtitles?
Yup, it's enabled. I've tried different settings with my TV dongle. In pure S/W mode the subtitles work, they also work in H/W+ mode.
But in H/W mode the don't. I don't have custom codec but I have sound so I presume that my dongle has AC3 codec built in the firmware.

Does MX Player lists the subtitle when you start in H/W decoder?
If it's loaded it will show a symbol.
If it's not showing, do the following
Start playing in HW decoder (you won't get subtitle as per your statement), then try in H/W+ (you may get subtitle). Now close the video & immediately goto Help | Bug Report. Save the logs and upload here.
For what container formats do the MicroDVD subtitles not show? Mp4? Mkv? Both?

@devshin Would you send me subtitle file (or video file is subtitle is embedded in a video file)?
I've checked some MicroDVD subtitles file but could not find any issue.
Hello,
I use MX player on MXQ S85 Android TV Box. It is working very well except audio stream changing, even I can click on the other language audio available, it keeps playing sound in first language when movie started...
I have tried with different files, it is always same problem. Other video players doesn't meet this issue. I would like continue use MX player because H265 files are well played.
Thank you

Probably it's due to unsupported audio codec...!

Sorry I did not put infos about it... apparently it is due to DTS ... The first stream is played well but it seems dual channel DTS makes troubles:
Video is Codec : H264 - MPEG-4 AVC (part 10) (avc1) Résolution : 1920x1058
Two streams are DTS and the second can't be played is DTS 1509 Kbps
Is it enough info ?
Thanks !

Probably your device may not have native dts decoder. Kindly use custom codec from the sticky post. When you use custom codecs you can play ac3 or dts tracks even if it's not natively supported by your device. But, the disadvantage is the 5.1 audio will be downmixed to stereo

But the first stream is in DTS and is well played and detected on my speakers system so it is not the device. I have found another video player who can also play both stream in DTS but I would prefer use MXplayer... :silly:
Hello everybody, I have this problem:
When I use hw decoder I get perfect sound but video is blurry.
When I change it to hw+ I have perfect video but no ddp or dts sound. Any solution?

Is it a local video or network stream?
HW decoder basically uses android mediaplayer API implemented on your device. If it is a network stream ( specifically HLS or DASH) it may happen due to adaptive playback. It will automatically select the best stream based on the current bandwidth. In HW+ or SW decoder, it will always play the first stream despite the bandwidth availability.
The problem occurs with local videos, mkv with ddp or dts sound. It is quite strange: Videos look like being projected on a screen with retention problem with hw. With hw+ videos are fine, but no sound
idn, but may restart will help?

hi,
I have an Minix U9-H box (android 6.0) and when I play full HD streaming files from my ip tv provider using HW+ decoder, the video quality is poor. It's working fine with HW or SW decoder (The codec used by mx player is ARM V7 NEON).
I checked also in perfect player and when using HW+, it seems the player downgrade the video resolution to SD format.
Any clue ?

It should be a bug in the system decoder. In HW+, MX Player passes the frames to the system decoders to directly decode. Probably, the resolution of the decoded frame might be low. We have encountered a similar issue in the past especially when the stream is interlaced. If it's the root cause, then it has to be fixed on the firmware. You will notice similar issues with all major video player apps which makes use of similar technology.

HW and HW+ uses GPU for H.264 decoding. They performance much better from SW which uses CPU for decoding. HW can perform better than HW+ in most of the Cases, but there is a chance it does not work smoothly on many devices.
Same
Same problem. SW is better than HW and HW+. (Android tv 8.1 - Mibox 3s)

It may happen when the Hardware Accelerated Decoders implemented on the device itself is buggy. Can you please contact us with screenshots of the playback on HW/HW+ and SW along with a bug reported collected from MX right after playing the file? It will help us to confirm the same.
There is no error, just low quality. HW and HW+ is same. SW is good.
The problem only occurs when viewing iptv (multicast - udp), watching the file on the hard disk is ok

It is one of the known issues on Xiaomi's TV boxes with Oreo and Nougat firmware. Based on our past investigation, it has been found that the hardware accelerated decoder's output resolution of the video frames is much lower than the actual frame size. As both HW and HW+ relies on the decoders shipped with the device, you can notice the issues on both. Request you to contact the device manufacturer so that they can fix the same on their firmware.
If it is possible, kindly share a link with us on PM or at [email protected] so that we can also escalate the same from our end.
I also tried on my phone (Mi Mix 2s - Android 9, MIUI 10) and it gave same results.

Can you please try any non-xiaomi device and check again? Can you also check whether it happens if you copy the stream to a file using FFmpeg? Without a sample clip or a link, we may not be able to seek the assistance of the Xiaomi team.

I don't have a non-xiaomi device. These are sample files. I saved them with VLC

Let me guess a bit: The format of the service provider is 1080i, this issue relates to the deinterlacing algorithm. With HW decoder, resolution halved.
maybe recode your video?
