This patch set adds audio_service_type to AVCodecContext and uses
it to set AVStream.disposition. For AC-3, the bitstream mode is
used to set audio_service_type and vice-versa.
example:
ffmpeg -i AllSamples.wav -ab 224k -audio_service_type vi -acodec ac3 -y
AllSamples_vi.mp4
ffmpeg -i AllSamples_vi.mp4
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'AllSamples_vi.mp4':
Stream #0.0(und): Audio: ac3, 48000 Hz, 2 channels, s16, 224 kb/s (visual
impaired)
Justin Ruggles (5):
Add audio_service_type field to AVCodecContext for encoding and
reporting of the service type in the audio bitstream.
Add APIchanges entry for audio_service_type.
Use audio_service_type to set stream disposition.
Get audio_service_type for AC-3 based on bitstream mode in the AC-3
parser and decoder, and vice-versa for the AC-3 encoder.
mov: set audio service type for AC-3 from bitstream mode in the
'dac3' atom.
