            Bug ID: 912
           Summary: avconv: video artifacts with h263p encoder
           Product: Libav
           Version: git HEAD
          Hardware: X86
                OS: Linux
            Status: NEW
          Severity: major
          Priority: ---
         Component: general
          Assignee: bugzilla at libav.org
          Reporter: eloi.bail at savoirfairelinux.com


I am working on a open source communication system: ring.cx
We use H263 codec because lot of SIP phone use only this codec. We see
systematic video artifacts using H263P encoder.

I reproduce it using avconv (on V11 and master)

avconv -v debug -f video4linux2 -input_format yuyv422 -s 1280x720  -r 10 -i
/dev/video0 -vcodec h263p out.mkv

I even try to check on previous version as it works fine using ffmpeg.

On tag v.0.8 both ffmpeg and avconv tool were used. I am able to have it work
without artifacts using ffmpeg command while Avconv fails.

It looks like this is an encoding issue probably due to missing/wrong parameter
but I am struggling to find what is wrong in the code.

Did someone encounter this issue ?
