Comment (by peloverde):
MediaInfo compares the average and max bitrates in the esds to determine
CBR vs VBR. For transmuxed files FFmpeg always sets max bitrate to avg
bitrate. It should be possible to create a compute_max_bitrate() function
just like compute_avg_bitrate() to create maximally complaint files. But I
don't know of any practical implications of this.
