FYI, I unistalled & reinstalled VideoStation & Advanced Media Extensions. Repatched VideoStation. Nothing changed.
However, while patching it said that a new version of the patcher v2.6 was out. Could it be the issue ?

Other info : The sound works on DS Video on iPhone and on the DS Video app on TV.

Hi KidWar75,

The new version available message is normal, it's displaying the same message for everyone even if you have latest version

The issue-report looks a bit cutted near the ffmpeg args (maybe copy paste didn't copy long lines), could you please resend the full report please ? :)

Thank you,
Does it work with other EAC3 / DTS movies ?

The smartphone and TV app is not supposed to work with these codecs so I guess the problem is because I force the use of lib_aac when lib_mp3lame is working fine

[KidWar75]

Just tried with :

• Tokyo.Vice.S02E06.I.Choose.You.1080p.AMZN.WEB-DL.DDP5.1.Atmos.H.264-FLUX which is EAC3 -> no problem.
• The.Fighter.2010.BluRay.1080p.x264.DTS.dxva-xander which is DTS -> No problem

[AlexPresso]

Okay I will make some tests and get back to you :)

Cheers buddy and thx again for your work! :)

Hi @KidWar75

Looks like the codec of your videos is not "vanilla" eac3, it's eac3_joc and it looks like it's not included in the ffmpeg version we're using (ffmpeg4), I tried on my NAS to run the following and it doesn't return any encoder / decoder support : ffmpeg -codecs | grep eac3_joc

I'm checking if we have a solution to add it, but vanilla eac3 is working

[KidWar75]

Hey!
Cheers for the answer.
Ye Vanilla eac3 is working fine, no worries on that end.

Hi Kidwar75,

By chance, have you tried with other ffmpeg versions ? like ffmpeg5 or ffmpeg6, I have no idea if it will work or not but it could be nice to give it a try

[KidWar75]

How do I do that ?
I'm a noob really, I just follow your steps and that's it ^^

[AlexPresso]

No worries :)
You can try it by:

• installing ffmpeg5 and/or ffmpeg6 from the Synology Packages Manager
• unpatch current version: curl https://raw.githubusercontent.com/AlexPresso/VideoStation-FFMPEG-Patcher/main/patcher.sh | bash -s -- -a unpatch
• patch again specifying ffmpeg version to use (i.e ffmpeg5) : curl https://raw.githubusercontent.com/AlexPresso/VideoStation-FFMPEG-Patcher/main/patcher.sh | bash -s -- -v 5

This example is for ffmpeg5, if you want to give it a try with ffmpeg6 or go back to ffmpeg4, you have to repeat the previous steps :)

PS: please note that using ffmpeg5 or ffmpeg6 might be eating a lot of your CPU / GPU depending on your hardware

[KidWar75]

All right !
What do you suggest ffmpeg 5 or 6 ?
I got a 920+
I'll try that when I got some time :)

[AlexPresso]

I have no idea if it would even work, you can start by trying ffmpeg5 then try ffmpeg6 if it's not working

[KidWar75]

Nop, doesn't work either with ffmpeg 5 or 6 :(

[AlexPresso]

Arf, sorry then, unfortunately, I can't do anything if the format is not supported by ffmpeg :(
