-----------------------------------+---------------------------------------
 The change by adding .flags_internal to the file "libavformat/spdifenc.c"
 causes audio passthrough to fail in mpv.
 The issue is reported here => https://github.com/mpv-
 player/mpv/issues/13794

 The log there says

 {{{
 [ad] In: profile=60 samplerate=48000
 [ffmpeg] spdif: spdif muxer does not support any stream of type unknown
 [ad] libavformat spdif initialization failed.
 }}}

 and playback is stuck there.

 This can be fixed by just deleting the last line in the file
 "libavformat/spdifenc.c"

 {{{
     .flags_internal    = FF_OFMT_FLAG_MAX_ONE_OF_EACH,
 }}}
