Andreas Rheinhardt 1f0bfdffe3 avfilter/vf_hwdownload: Fix leak of formats list upon error 
If adding the list of input formats to its AVFilterLink fails, the list
of output formats (which has not been attached to permanent storage yet)
leaks. This has been fixed by not creating the lists of in- and output
formats simultaneously. Instead creating said lists is relegated to
ff_formats_pixdesc_filter() (this also avoids the reallocations implicit
in using ff_add_format()) and the second list is only created after (and
if) the first list has been permanently attached to its AVFilterLink.

  • 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.
