avcodec/h2645_parse: Ignore NAL with nuh_layer_id == 63 
Comply with "For purposes other than determining the amount of data in the decoding units
of the bitstream, decoders shall ignore all data that follow the value 63 for nuh_layer_id in a NAL unit"
Rec. ITU-T H.265 v8 (08/2021)	Page 67

Fixes: index 63 out of bounds for type 'const int8_t[63]' (aka 'const signed char[63]')
Fixes: clusterfuzz-testcase-fuzzer_loadfile-5109286752026624

FFmpeg README

FFmpeg is a collection of libraries and tools to process multimedia content such as audio, video, subtitles and related metadata.

Libraries

  • libavcodec provides implementation of a wider range of codecs.
  • libavformat implements streaming protocols, container formats and basic I/O access.
  • libavutil includes hashers, decompressors and miscellaneous utility functions.
  • libavfilter provides means to alter decoded audio and video through a directed graph of connected filters.
  • libavdevice provides an abstraction to access capture and playback devices.
  • libswresample implements audio mixing and resampling routines.
  • libswscale implements color conversion and scaling routines.

Tools

  • ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
  • ffplay is a minimalistic multimedia player.
  • ffprobe is a simple analysis tool to inspect multimedia content.
  • Additional small tools such as aviocat, ismindex and qt-faststart.
