Andreas Rheinhardt b96ba62bdd avcodec/mpegvideo_enc: Fix abort on allocation errors 
mpegvideo_enc uses a fixed-size array of Pictures; a slot is
considered taken if the Picture's AVFrame is set.
When an error happens after a slot has been taken, this Picture
has typically not been reset and is therefore not usable for
future requests. The code aborts when one runs out of slots
and this can happen in case of allocation failures.
Fix this by always unreferencing a Picture in case of errors.

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.
