Linjie Fu 091341f2ab lavc/pthread_frame: Update user context in ff_frame_thread_free 
Resolution/format changes lead to re-initialization of hardware
accelerations(vaapi/dxva2/..) with new hwaccel_priv_data in
the worker-thread. But hwaccel_priv_data in user context won't
be updated until the resolution changing frame is output.

A termination with "-vframes" just after the reinit will lead to:
    1. memory leak in worker-thread.
    2. double free in user-thread.

Update user context in ff_frame_thread_free with the last thread
submit_packet() was called on.

To reproduce:
ffmpeg -hwaccel vaapi(dxva2) -v verbose -i
    fate-suite/h264/reinit-large_420_8-to-small_420_8.h264 -pix_fmt nv12
    -f rawvideo -vsync passthrough -vframes 47 -y out.yuv

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 a mean to alter decoded Audio and Video through chain of 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.
