Comment (by Arnaud):

 Thanks for your reply.

 How can I check if the file has only on recovery point and if that can be
 the issue?

 I tried to figure this out by adding a breakpoints in
 h264.c:decode_recovery_point but never get there, using my "buggy" file,
 but also some other files (e.g. [1] from [2]) for which seeking works.
