[FFmpeg-devel] [PATCH 0/2] Fix silent audio when channel layout specified with trailing c

[Simon Thelen]

When specifying the output channel layout with a trailing 'c' such as 
'1c' or '2c', the pad filter created silent output files. Leaving the
trailing 'c' away resulted in correct output files, but generated a
warning that the syntax was deprecated.

The first patch fixes two bugs in ff_parse_channel_layout including an
off-by-one and an issue in the parsing helper for unknown channel
layouts.

The second patch ensures that the channel layout is returned correctly
when FF_API_GET_CHANNEL_LAYOUT_COMPAT is set.

Simon Thelen (2):
  libavfilter/formats: Fix parsing of channel specifications with a    
    trailing 'c'.
  libavutil/channel_layout: Correctly return layout when channel    
    specification ends with a trailing 'c'.
