Carl -
Here's the output after adding the logging -
float: 0, integer: 4, bps: 24, packed: 8
I ended up modifying the code to make things work with both the mini's line-in,
and soundflower. Sadly my machine is having a hard time keeping up. Here's the
code though (in avfoundation.m):
//print some info, trying to figure out what soundflower/10.7.5 is giving us,
and why it's exiting with unsupported audio
printf("float: %d, integer: %d, bps: %d, packed: %d , formatId: %d\n",
ctx->audio_float, ctx->audio_signed_integer,ctx->audio_bits_per_sample,
ctx->audio_packed, basic_desc->mFormatID);
if (basic_desc->mFormatID == kAudioFormatLinearPCM &&
ctx->audio_float &&
ctx->audio_bits_per_sample == 32 &&
ctx->audio_packed) {
stream->codec->codec_id = ctx->audio_be ? AV_CODEC_ID_PCM_F32BE :
AV_CODEC_ID_PCM_F32LE;
} else if (basic_desc->mFormatID == kAudioFormatLinearPCM &&
ctx->audio_signed_integer &&
ctx->audio_bits_per_sample == 16 &&
ctx->audio_packed) {
stream->codec->codec_id = ctx->audio_be ? AV_CODEC_ID_PCM_S16BE :
AV_CODEC_ID_PCM_S16LE;
} else if (basic_desc->mFormatID == kAudioFormatLinearPCM &&
ctx->audio_signed_integer &&
ctx->audio_bits_per_sample == 24 &&
ctx->audio_packed) {
//mac mini, osx 10.7.5 built-in line input
stream->codec->codec_id = ctx->audio_be ? AV_CODEC_ID_PCM_S24BE :
AV_CODEC_ID_PCM_S24LE;
} else if (basic_desc->mFormatID == kAudioFormatLinearPCM &&
ctx->audio_signed_integer &&
ctx->audio_bits_per_sample == 32 &&
ctx->audio_packed) {
//mac mini, osx 10.7.5 soundflower input
stream->codec->codec_id = ctx->audio_be ? AV_CODEC_ID_PCM_S32BE :
AV_CODEC_ID_PCM_S32LE;
} else {
av_log(s, AV_LOG_ERROR, "audio format is not supported\n");
return 1;
}
