Ubuntu/ Vaapi/ AMD WX5100: disable B-Frames?

[labor4 0]

Hi Community

 

Is there a way to disable B-Frames in h264 enc/transcode?

It seems setting "-bf 0" seems to let me encode via GPU. At least in a rough CLI try.

It fails via Emby.

 

Thanks

Hi there, why do you feel that it fails?

[labor4 0]

 

Chrome 73.0.3683.103

Emby 4.2.0.0 beta

Is that the no compatible streams error message?

[labor4 0]

yes

[labor4 0]

If I disable h264 encode via GPU, it works.

[Luke 42077]

Can you please attach a complete ffmpeg log example? thanks.

Thanks

Hi Community

 

Is there a way to disable B-Frames in h264 enc/transcode?

It seems setting "-bf 0" seems to let me encode via GPU. At least in a rough CLI try.

It fails via Emby.

 

From your logs, I can't see that it "fails via Emby". 

Of course, there's that warning in the log, but then it proceeds to transcode just normally.

 

So I don't quite understand your conclusion " setting "-bf 0" seems to let me encode via GPU" 

 

What you could do is to create a few segments using both ways (Emby original command line and yours adding '-bf 0'), then we could analyze the resulting segments.

 

Another thing to try: Press F12 in the browser before playback and switch to the 'Console' tab to look for an error.

I think you're right and my assumption was probably wrong, since it encoded anyway.

I felt strengthened in that opinion since I extracted the command and ffmpeg didn't let me pass this problem without the option.

But you guys have probably solved this differently, I guess.

 

Attached is my chrome console.

There are errors. It starts at line 2.

 

I cannot say much, other than line 1 is the moment after I pressed play.

 

Thanks a lot for looking into this!

 

best,

manu
