Philip Langdale 1c61c24f5f vulkan/hevc: handle missing active PPS 
I don't pretend to understand how we get into this situation, but there
are files out there where we can end up with the active PPS not being
identified when we call vk_hevc_end_frame. In these situations today,
we will segfault. So, before we give up, see if we can get the active
PPS id from the slice header, and use that if possible.

If that still doesn't work, return an error instead of segfaulting.

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.
