           Summary: rtpvp8pay fails on error-resilient stream
    Classification: Platform
           Product: GStreamer
           Version: git
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: Normal
         Component: gst-plugins-bad
        AssignedTo: gstreamer-bugs at lists.freedesktop.org
        ReportedBy: bug-track at fisher-privat.net

     GNOME version: ---


Current rtpvp8pay fail on this pipe:
... ! vp8enc error-resilient=true ! rtpvp8pay ! ...

the reason is, this check in function gst_rtp_vp8_pay_parse_frame:
   if (header_size + (partitions - 1) * 3 >= GST_BUFFER_SIZE (buffer))
     goto error;

by stream with error-resilient=false, partitions=1, so result of this check is
less then buffer_size. With error-resilient=true, usually partitions=4 (after
partitions = 1 << tmp8), and the buffer size is too small.

I assume:
- vp8 should produce bigger buffer by samples with more then one partition.
- libvpx is brocken?
- rtpvp8pay should recalculate the buffer instead of fail.

Any other suggestions?

Regards,
  Alexey.
