Andreas Rheinhardt 70d226575a avcodec/cbs_sei: Fix leak of AVBufferRef on error 
An AVBufferRef (and the corresponding AVBuffer and the underlying actual
buffer) would leak in ff_cbs_sei_add_message() on error in case an error
happened after its creation and before it has been attached to more
permanent storage. Fix this by only creating the AVBufferRef immediately
before attaching it to its intended target position.

(Given that no SEI message currently created is refcounted, the above
can't happen at the moment. But Coverity already nevertheless noticed:
This commit fixes Coverity issue #1473521.)

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.
