Description (last modified by cehoyos)

http://thread.gmane.org/gmane.comp.video.ffmpeg.user/44281/focus=46797
A user uploaded a transport stream recorded with a Panasonic AG-HMC150 camera for which FFmpeg shows an error message (only) when decoding the first frame (an I-frame, not an IDR-frame).
The same error is shown when only reading the raw I-frame since d9ced9f (related to ticket #711), the frame can be decoded with the reference decoder (bit-identical with FFmpeg).

I have access to a Panasonic AG-HMC150 camera if additional samples are required.
