Zhao Zhili 25812d3033 avcodec/bsf/h264_mp4toannexb: Fix mixed bitstream format 
This bsf converts AV_PKT_DATA_NEW_EXTRADATA side data in avcc format
to in-band annexb format. However, the side data wasn't been removed
and copied from input packet to output packet. So the output packet
has mixed bitstream format. We don't support mixed bitstream format.
For example, h264_metadata report error in the following case:

ffmpeg -i foo.flv \
  -bsf:v "h264_mp4toannexb,h264_metadata" \
  -c copy -f null

This patch removed NEW_EXTRADATA side data after process.

This patch also add a check so only NEW_EXTRADATA in avcc format is
processed. NEW_EXTRADATA in annexb format is copied to output as is.

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.
