Andreas Rheinhardt 38f234c06e avcodec/vc1dec: Set pointers for hwaccel even without hwaccel 
VC-1 uses a 0x03 escaping scheme like H.26x and our decoder
unescapes data for this purpose, but hardware accelerations
just want the data as-is and therefore get fed the original
data. The pointers to the actual data are only setcorrectly
if avctx->hwaccel is set (after all, they are only used in
this case).

There are two problems with this: The first is that the branch
is pointless; the second is that it is harmful, because
a hardware acceleration may be added after the packet has been
parsed (in case there is a reconfiguration e.g. due to frame
size changes) in which case decoding the first few frames
won't work.

So delete these branches.

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.

Documentation
