Hi
Not sure if this is the place to post regarding an issue with hevc_vaapi,
but since i have absolutely no other headway anywhere and this is driving
me crazy, posting it here.
There is a abnormal behavior when encoding using hevc_vaapi, and has been
posted on https://trac.ffmpeg.org/ticket/5821, i have been trying to look
for an answer for the same all over the net and have not been able to
understand it.
Can somebody please have a look at this and point me in the right
direction
please.
...
the whole encoding process runs perfectly smooth, no warnings or errors.
but the resulting video has problem. like frames go back and forth from
time to time. i call it 'jerky'.
Thanks
Mani
Encoding HEVC via VAAPI may use hardware acceleration in the GPU, but
certainly not the pure software encoder x265 running on your CPU only.
Therefore x265 is certainly not responsible for such issues.
To discover the reasons, people may need samples of the original source
and the converted result, to analyze both the video structure (frame
order, GOP complexity, possible interlacing or telecine) and the
bitstreams (maybe there are indeed technical HEVC encoding errors). But
the ffmpeg developers and the intel driver developers are better targets
than the x265 developers to solve this issue.
