Comment (by mkver):

 Replying to [comment:1 jamrial]:
 > You should use the h264_mp4toannexb bitstream filter for this, not
 dump_extradata
 This was actually the first thing I checked and it didn't work. But now I
 did this with the sample I uploaded here and it worked. After creating a
 different sample I found out that the h264_mp4toannexb bitstream filter
 seems to insert the SPS/PPS only in front of IDR frames, not I frames with
 a recovery point SEI message. But this would be a different ticket.
 Returning to this one: Is the behaviour I encountered intended behaviour?
 Or does this count as a bug?
