[FFmpeg-devel] [mov] Bail when invalid sample data is present.

[Dale Curtis]

[mov] Bail when invalid sample data is present.

ctts data in ffmpeg relies on the index entries array to be 1:1
with samples... yet sc->sample_count can be read directly from
the 'stsz' box and index entries are only generated if a chunk
count has been read from 'stco' box.

Ensure that if sc->sample_count > 0, sc->chunk_count is too.

This should be applied on top of the ctts fixes in my previous patch.
