Additional context

[AlexPresso]

Hey,
Which SynoCommunity ffmpeg version are you using ?

[GMib]

hi, 4.3.2-38

[AlexPresso]

The issue is probably due to the fact you're not using the wrapper from my patcher.

You only uninstalled VideoStation and not VideoStation and Advanced Media Extensions. Then the old wrapper from another repository wasn't replaced in Advanced Media Extensions.

Please proceed in this order:

• uninstall VideoStation (keep your library)
• uninstall Advanced Media Extensions
• Reinstall VideoStation (will automatically install Advanced Media Extensions)
• Re-execute the patch

[GMib]

thx for help, now video work but not sound.

https://gist.github.com/GMib/d21de583061c23de9cce54505fe9a4ac#file-gistfile1-txt

[AlexPresso]

The gist you provided is the same log file than the one you already sent ;)

But there's a way to get aditional details on why it doesn't work. When a video is playing, the wrapper creates a temporary debug file storing infos from ffmpeg.
To get its content, you can:

• Start the video on VideoStation, wait for the video to play and put the browser in background (keep the video playing)
• Connect through SSH
• Impersonate root user (sudo -i)
• Go to /tmp (cd /tmp)
• Type ls -al | grep ffmpeg to list all files containing "ffmpeg"
• You should see two files, the ffmpeg.log and a new one, that should look like ffmpeg-FFMxxxx.stderr
• Type tail -100 ffmpeg-FFMxxxx.stderr with the filename you got previously, to print its content to the console
• Copy paste the content to a gist

[AlexPresso]

Perfect, thank you, so there's no error during stream transcoding.
Could you please do the same with

• head -50 ffmpeg-FFMxxxx.stderr instead of tail

[GMib]

the tail -200 of ffmpg.log (sorry i'm useless in bash :(
https://gist.github.com/GMib/dcc266e6fb44fdb333fc91edea61615a#file-gistfile1-txt

the head : https://gist.github.com/GMib/de4b5956b7dc208ddda36dae032eaf07#file-gistfile1-txt

[AlexPresso]

No worries ;)

I'm sorry, I should have given you a higher count 😶, but the head part is incomplete, the video is having a lot of streams (video and audio sources) so it takes a lot of lines to print it all out.
Could you increase the lines count to 300 or more if needed (head -300 ffmpeg-FFMxxxx.stderr) ?

[GMib]

https://gist.github.com/GMib/a2e8153a7ed25de2125aabe7a25b488b#file-gistfile1-txt

[AlexPresso]

Perfect ! Thank you.

As I can tell from the logs, everything is supposed to work as expected, FFMPEG is tuned to transcode from EAC3 to MP3 and there's no error when the stream segments are being processed.

I'm sorry to ask, but are you sure you haven't muted VideoStation / Chrome / your computer / speakers ? 😉

[GMib]

Yes i'm sure, video with aac work fine, video with ac3 or eac3 have no sound and playback cut often.

[AlexPresso]

Could you upload this specific file on a file host (media fire, wetransfer, ...) and post the link please

[GMib]

trying to upload, it's strange, some movie with ac3 have sound work some not

[GMib]

[AlexPresso]

My NAS is playing it sucessfully, but the audio only starts to play near 00:00:17 and stops randomly. Since that problem occurs in VLC too, I'm pretty sure it's a file related issue, which probably happened when the uploader merged/muxed the video and audio streams.

Unfortunately, I won't be able to do a lot on that side, I'm also watching HEVC + EAC3 series and never had that issue so far.

[GMib]

There is no sound before 00:00:17 it's normal, ripper had removed this part because it was in english, for me it not stop randomly after, i've seen this with kodi without problem, and tested now with kmplayer. I can't play movies or tvshows with eac3, I've just see also a quality problem, picture is very pixelized. i never had issue before i update in dsm7 (don't remind what method i've used before update for playing eac3). I actually test Plex because videostation is too bad. thank you for taking the time to help me

[AlexPresso]

Yeah, VideoStation is really bad, if you have the opportunity to switch to another tool, Jellyfin is (in my opinion) a better free alternative to Plex.
The quality "problem" is due to two things:

• the realtime transcoding: when ffmpeg converts a video codec to another (i.e. HEVC --> H.264), it's losing a bit quality.
• because the realtime transcoding can be hard for some CPUs, ffmpeg-wrapper is tuned to use a 1024kb buffer size, which you can double / triple if you have a good CPU.

[GMib]

I discarded jellyfin because my nas is not docker compatible but i just see there is community package, i will test that, thx

[GMenethil]

it works on web video station, but on android the playing icon endless turn
