Andreas Rheinhardt 14015b9e15 avcodec/hevcdec: Check early whether film grain is supported, fix race 
Applying film grain happens after ff_thread_finish_setup(),
so the parameters synced in hevc_update_thread_context() must not
be modified. But this is exactly what happens in case applying
film grain fails. (The likely result is that in case of frame threading
an uninitialized frame is output.)

Given that it is actually very easy to know in advance whether
ff_h274_apply_film_grain() supports a given set of parameters,
one can check for this before ff_thread_finish_setup()
and avoid allocating an unused buffer lateron.

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.
