avdevice/decklink_enc: Add support for compressed AC-3 output over SDI
Extend the decklink output to include support for compressed AC-3, encapsulated using the SMPTE ST 377:2015 standard. This functionality can be exercised by using the "copy" codec when the input audio stream is AC-3. For example: ./ffmpeg -i ~/foo.ts -codec:a copy -f decklink 'UltraStudio Mini Monitor' Note that the default behavior continues to be to do PCM output, which means without specifying the copy codec a stream containing AC-3 will be decoded and downmixed to stereo audio before output. Thanks to Marton Balint for providing feedback. Signed-off-by: Devin Heitmueller <dheitmueller@ltnglobal.com> Signed-off-by: Marton Balint <cus@passwd.hu>
