VAAPI transcoding problem? am I using wrong version?

Added by Evren Yurtesen about 5 years ago

I have "HTS Tvheadend 4.2.9~pre+201910311127-0~built201910311332~gitcfa450e~ubuntu19.10.1" installed from mamarley/stable repository.

I am able to use VAAPI with ffmpeg locally. In Tvheadend stream I see 'hevc_vaapi: H265/HEVC (VAAPI)'

But if I try to use it when recording, it just fails:

If I try to stream it to another device it also fails

Do I need 4.3 version of tvheadend?

Thanks!

@"M A Ben Amara" You did not record 4:3 streams. All your recordings in your drive are 1280x720, therefore 16:9 natively.
You are lucky that your channels are streaming like that. In my case the stream resolution is 720x 576 but with 16:9 aspect ratio.
You should really see the files I uploaded to that bug report and re-encode them using ffmpeg to see what happens :)
