Comment (by ttcoder):
@pulkomandy -- Working on adapting/testing my apps in hrev48150 and found
one which is allergic to FLAC -- it feeds HDA line-input (instead of a
source file .wav) to the encoder, so the samples are 32 bits instead of
B_AUDIO_SHORT and 96KHz instead of 44 KHz, and ffmpeg/FLAC replies with
`"unhandled sample_fmt"` or something. If I hack ''both'' in the format I
pass to BMediaFile::CreateTrack() / CommitHeader() like thus
{{{
fmt.u.raw_audio.format = media_raw_audio_format::B_AUDIO_SHORT;
fmt.u.raw_audio.frame_rate = 44000.0;
}}}
then I get a B_OK and the file is created, but of course the audible
content is mostly junk.
Once I solve this I can wait a while for the rest of the ticket
enhancement (ogg/vorbis or other lossy codec).
Questions..
- how much work involved in making flac accept 32 bits samples instead of
16.. and high-KHz sample-rates (though that latter can probably be fixed
another way, by changing HDA input in Media Prefs).
- is it possible to re-enable Wav/Pcm-Raw-Audio, in addition to FLAC? It
which worked well in my testing this morning in 47991.
