Raspberry Pi also used to have problem with packed B frames, they workaround it
in the player and later a fix was provided in the PI firmware.

[rbp/omxplayer] fixed playback of mpeg4 with packed B frames. thx popcornmix
for the workaround
https://github.com/xbmc/xbmc/commit/e08fee30d1c9ca755ddb5c9833a19b8d1cbabff5

[rbp/omxplayer] reverted e08fee3 the PI firmware handles this now. 
https://github.com/xbmc/xbmc/commit/f868fc4808e19bee60d7a83e8aa5f09b3bc861c2

// avi files with packed B frames have "not-coded" dummy frames that decoder
doesn't like
if (m_codingType == OMX_VIDEO_CodingMPEG4 && iSize <= 7)
  return true;

I will ckeck if above workaround "temporary" fixes the issue in the sink.
Although most probably mpeg4videoparser should do this.
