            Bug ID: 106110
           Summary: vaapi encoding with gstreamer 1.14 doesn't work
           Product: Mesa
           Version: git
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: haagch@frickel.club
        QA Contact: dri-devel@lists.freedesktop.org

It could also be a gstreamer-vaapi bug since it happens only since gstreamer
1.14, but I have seen nobody else complain anywhere, so it must work for some
people at least.

RX 480, recent mesa git revisions, Linux 4.15 - drm-next-4.18-wip

To test:
gst-launch-1.0 videotestsrc ! vaapih264enc ! "video/x-h264,profile=baseline" !
h264parse ! matroskamux ! filesink location=output.mkv

With gstreamer 1.14 this never starts encoding and produces a 0 byte file when
cancelling with ctrl+c.

With gstreamer 1.12.4 it worked fine.

remco on #radeon figured out that it works when adding
stream-format=byte-stream to the video format, like this:

gst-launch-1.0 videotestsrc ! vaapih264enc !
"video/x-h264,profile=baseline,stream-format=byte-stream" ! h264parse !
matroskamux ! filesink location=output.mkv

I was on older gits for gstreamer when I saw this around 1.13<something>

matroska and mp4mux didn't work, but raw 264 and avimux did.

I updated to current gits before seeing the workaround and now it seems
gstreamer produces junk whatever I do :-).

FWIW I found the "nothing works" cause = the next commit in gstreamer-vaapi
after 1.14 tag =

fa77b2bf vaapiencode: h264: find best profile in those available

With that reverted the additional stream-format=byte-stream makes mkv/mp4 work
again.

According to gstreamer IRC my issue is something that should be reported as a
bug to gstreamer. Yours probably too.
