Try SW or HW+ decoder. HW decoder may not play Opus audio because HW decoder is no better than stock decoder.

When using HW+ decoder it played the file the first time I but each time after that the player changes to HW mode even though it is set to use HW+ in the options, when I try to change to HW+ mode by clicking on the HW icon a message is displayed that HW+ is not supported.
I have closed the app and the same thing happens.
when using SW mode it plays fine as far as I can tell.will do more tests....

The sample video is encoded in HEVC. Most of the devices doesn't support HEVC natively. H/W & H/W+ decoders use your system decoders. If your device don't have native support for HEVC, H/W or H/W+ decoder can't play that video.
In my S5 it automatically switches to SW & Play the Audio/video without any issue.

My device does support HEVC natively.
but not Opus audio I assume, which is why it does not play in HW mode but does in SW and HW+ modes.
I still need to do more testing....

[Question][Bug] HW decoder for HEVC on MKV videos

I am using HTC E8 and as snapdragon 801 supports HEVC playback on HW decoder, it is perfectly playable for mp4 videos. However, if the same video is encoded into a MKV format with all the encoding settings the same what so ever or just remuxed into a MKV, mx player just says HW decoder is not supported, forced to use the sluggish SW decoder. Below are the media info for the videos to refer:
This the mp4 version, which is playable through the HW decoder smoothly.

Welcome to the club, many thread about this bug but no response so far

@CHEchenyu @lieuliau
H/W decoder basically uses android mediaplayer to play the video. If there is any problem in H/W, it might be from the system itself.
How did you converted the video to mkv?
If you have re encoded with same parameters, kindly try to remux the mp4 video with "mkvtoolnix" instead of re encoding.
If you still have issues, kindly collect the logs immediately after playing the video & upload here.

Same problem as above, using MeGui to encode it to HEVC mkv.
I just remuxed the same encoded file to mp4, now it works on HW decoder. Weird.

Opus audio 6ch track mapped wrong to stereo output

Getting speach/dialog out the right speaker and surround sounds out of the left speaker.
Enabling mono audio sends speach to both speakers - however now sound is mono...
Works fine on computer, proper mapping, speach and sfx in both left and right speakers.

It's expected behaviour. MX Player audio output is always stereo.
We have implemented audio passthrough. But, not all codecs are supported in passthrough. And your audio receiver should also support the decoding of the particular codec.
We will forward your concern to our developer team.

Not sure that addresses my issue. (6ch input audio being mapped correctly to 2ch output)
Playing Ac3 or other 6ch audio, get dialog in both speakers...
Hopefully this was a canned response and the problem was actually understood.
I fixed it by transcoding all the files via manual downmixing and producing a dual audio file with the original 6ch audio and the proper stereo 2ch downmix audio.

Can you share a sample clip?
I don't have any such issues.

Our development team has tried to reproduce the issue. But, couldn't reproduce it.
It will be helpful if you can share the video with us. We will test it with our test devices.

HW Opus work only with 2 ch
Hi, I have the same problem with Opus sound track.
I found it work as expected when not use HW+ for audio (disable opus in HW audio decoder)
When use HW, MX Player play only R and L channel.. not play central channel.
I enable HW for OPUS to solve SW decoder problem, with specific bitrate

We have managed to get the same video based on @SoreGums metadata.
After looking at the video, it seems to be channel mapping issue.
The channel mapping order on the video is FL+FR+FC+LFE+BL+BR. But, according to the opus specification, it should be FL+FC+FR+BL+BR+LFE.
If you use HW decoder or HW+ Audio Decoder (If you have enabled in settings) for Opus, Then you will face the issues. Most of the device has opus decoders from Google which expects the channel order as per the Opus specification. So, It downmixes the wrong channels based on the standard order.
On FFMpeg based players, FFMpeg follows the FL+FR+FC+LFE+BL+BR layout. So, it won't be an issue.
You can enable SW audio from audio track selection panel as a workaround. In our tests, when SW audio is used there is no issue.

This video cannot play correctly with Mx player

Can you specify what happens exactly?
Is it possible to share a sample clip & bug report from MX Player

It only can play with hardware decode,cannot with hardware decode + and software decode,have no picture. With hardware decode,it only can play half movie.
I use mpc-hc on pc,it can play well.

It looks like a partially downloaded/corrupted video. FFMpeg has failed to detect pixel format & failed to identify keyframes.
Can you share the video with us? We need to analyse the video.

Sorry, I can't,it's a porn video.?

It's very difficult to address the issue without checking the video.
If it's possible, upload the video somewhere else like Google Drive & shares the link by PM.

1. Launch VLC Player and go to Media, and then select Convert or Save
2: Next, add input files or streams that need to be transcoded, and then press Convert or Save
3: In the Convert window that appears, provide the file name for the destination file
4: Next, select the desired Codec from the profile list.
6: You can also select to add a new profile or delete any existing profile
7: Next, press Start
Above are the techniques to repair video files. You will be able to play your videos in VLC player or other media players. If not, then go for Video Repair Tool!

Our developers are working on it. We will improve the broken file handling issues in future versions.

Question Samsung Scalable Codec Support on Watch4

Does anyone know if Samsung Scalable Codec is supported on Watch4?

When audio is playing on the watch look in Developer options it will show which codec is in use.
If it's showing the SSC codec in use or can be set to it (and remains after closing Developer options then reopening and rechecking) it does.

I only see animation, battery, or 3gpp in developer options. There isn't anything which shows the bluetooth codec on the watch.

Look on the phone as the watch is the slave I suspect.

No, the headset isn't paired to the phone. Anyway, I found another way, I enabled BT Snoop Logging and checked logcat in ADB. The codec is SSC, so it seems SSC is supported on watch4.

Thank you. I was searching Google for the Samsung Galaxy Watch5 Watch 5 Pro LTE version on how to find out which bluetooth audio codec was being used and stumbled on this article. What I did find out is that the Watch5 can use or shall I say uses AAC codec and SSC codec althrough using the logcat.
Bluetooth snoop logging turned on and debug over wi-fi. Connect adb to 192.168.1.232:5555 (yours might be different) had the watch set to diconnect the earbuds and idle over youtube music track just before playing. Entered "adb -s 192.168.1.232:5555 logcat *:I" on the computer, clicked play on the watch, selected the earbud wanting to test, heard the music, ctrl + C on the computer running adb. Copied cmd window (Ctrl + A, Ctrl + C) over to Notepad (Ctrl +V). Started searching and combing through the log.
For the Pixel buds it said ccodec aac and Galaxy Buds2 Pro it said SSC and tried to execute aac codec but then said SSC was in use.
Nice to know what's working.
On SENNHEISER HD 450BT which supports aptX only gets AAC
