Hello,
my main goal is to find a cheap device with vaapi support to decode mpeg 2
video to h264 and finally hls in different quality levels. For this reason
i'm working on the belkin z85 right now. On this machine i'm trying right
now to decode an udp mpeg2 livestream with vaapi support into an mpeg4 file.
On my newer device the following command is running without any issues with
ffmpeg version n4.2.2 : /sudo ffmpeg -vaapi_device /dev/dri/renderD128 -i
udp://multicastip:1234 -an -vf
'format=nv12,hwupload,scale_vaapi=w=1280:h=768,deinterlace_vaapi' -map 0:0
-c:v h264_vaapi test.mp4/
Which VAProfile does it mean? Normal Encoding without scaling is working.
Softwareencoding with libx264 is working too. I'm new to the whole topic, so
i have to read and study a lot to get the puzzle of the whole picture - does
anyone has an idea what i can do to get vapi_scaling working? ;-)
The same command on the z85 with ffmpeg version 4.2.2-1ubuntu1 gave me the
following error message:
[h264 @ 0x5643ff5d1d80] co located POCs unavailable
