Hi,
The width 720 is OK now. Colors are still wrong. It seems from more
testing that it's not just I420, inputting YV12 is also wrong, which
makes me think that the conversions could be producing nv21 rather
than nv12.
I updated my gstreamer to current git just in case it changed something
but it didn't, though they decided to make vaapi264enc default to high,
so now I have to add ! video/x-h264,profile=baseline ! everywhere.
ffmepeg/avconv no longer hit the division by zero.
There is something a bit strange about their rate control though, it's
like there is a max bitrate per frame limit - maybe they are sending
a min qp as well as bitrate or something, but I think it may be more
complicated that that.
Below this limit bitrate control works as expected with varying
framerates eg. 2560x1440 24mbit fps 50 and 25 = OK, start going higher
and things start getting limited for the lower fps. The source is not
limiting, qp is high 20s at this rate/fps.
Of course this may just be an ffmpeg/avconv issue when the patches go
in I will ask the author of the vaapi code (who IIRC has a bonaire) so
will be able to test.
Another ffmpeg specific feature is that though the files made play OK,
the JM ref decoder doesn't like them as below. It was always like this
though I can't recall the frame numbering being in 4s IIRC it used to
be paired like gstreamer.
gstreamer doesn't have the POC issue, example output below.
