[FFmpeg-devel] [PATCH 2/6] avfilter/af_channelmap: fix mapping if in_channel was a string but out_channel was not specified

[Marton Balint <cus@passwd.hu>]

In this case in_channel_idx was never set and the default 0 was used.
Suprisingly no one noticed that the respective fate test output was wrong.
