Fixes a regression inca2f19b9ccwith some mov/mp4 files. The files have several NAL units in the supposed single NAL unit after the size field. Annex B start code prefixes are used to separate them. The first NAL unit is correctly parsed but the buffer does not point to the next size field. Instead semi random data (it seems to be the rbsp_stop_one_bit and the start code prefix) is then parsed as length and will exceed the remaining length of the buffer. Patch based on the code in h264's decode_nal_units() and a similar patch by Hendrik Leppkes in FFmpeg (a9bb4cf87d). Bug-Id: ffmpeg/trac5529 Reported-By: Vittorio Giovara
