There is a integer overflow in media_tools/av_parsers.c in the gf_avc_read_pps_bs_internal in GPAC 1.0.1. pps_id may be a negative number, so it will not return. However, avc->pps only has 255 unit, so there is an overflow, which results a crash.Referenceshttps://github.com/gpac/gpac/issues/1720https://github.com/gpac/gpac/commit/51cdb67ff7c5f1242ac58c5aa603ceaf1793b788
