Hi,

i've tried using youtube-dl for downloadung 4k videos and merge the audio afterwards but after "[ffmpeg] Merging formats into ..." it get the error "ERROR: Unrecognized option 'c'". The ffmpeg Version is 0.8.10 which i compiled myself.

is this a known problem and what could be a possible fix?

Thanks!

Julian
