Comment (by Balling):

 Replying to [comment:19 John Dury]:
 > I tried adding "-extra_hw_frames 5" and it still fails on latest build
 (07/27) of gyan.

 try 6 and more. Again, that is the bug here, since it beaks after 10th (-b
 debug)

 [h264 @ 000002b1809d5fc0] nal_unit_type: 1(Coded slice of a non-IDR
 picture), nal_ref_idc: 0


 BTW, razy that there is no space there before bracket. See:
 https://github.com/FFmpeg/FFmpeg/blob/870bfe16a12bf09dca3a4ae27ef6f81a2de80c40/libavcodec/h2645_parse.c#L307
 (and line 324).
