Comment (by Marton Balint):

 The file does not signal keyframes and by default stream copy ignores all
 packets before the first keyframe.

 You can use the {{{-copyinkf}}} output option to stream copy such a file.

 Maybe a warning should be added if an unusually large number of packets
 are dropped before starting stream copy.
