ffmpeg | branch: master | Anton Khirnov <anton at khirnov.net> | Sun May  7 19:38:51 2023 +0200| [7be945a011917f3cff0ca8d7c09e0a71fe31d2c2] | committer: Anton Khirnov

fftools/ffmpeg: rename transcode_init()

It does no initialization anymore, except for setting
transcode_init_done - the bulk of the function is printing the
input/output maps. It also cannot fail anymore, so remove the useless
return value.
