Comment (by Tjoppen):

 What kind of thing do you have that spits out AVI files that claim to have
 audio when they don't? I would suggest addressing that first of all.
 There's only so much we can do to accommodate weird workflows.

 The A/V sync logic in ffmpeg will buffer all of those video packets
 waiting for audio that never arrives. For any non-trivial file this would
 eventually exhaust all available memory.

 I looked a bit at mxfenc.c, and mxf_write_packet() never gets called. This
 coupled with MXF being a very picky format leads to problems. A better
 error message might be in order however.
