I am trying to parse bytes by opening a audio file (M4A), reading 2048 bytes in a loop and passing it to AudioFileStreamParseBytes. This does not call the callback with the property kAudioFileStreamProperty_ReadyToProducePackets
. But the property kAudioFileStreamProperty_FileFormat
is being successfully called. (So I know the callback mechanism is working.)
Questions :
AudioFileStreamParseBytes
to parse audio data by reading from a local file ? Most examples show how to use AudioFileStreamParseBytes
by parsing HTTP
stream data, but not reading from a local file. NOTE : The reason I am not using AudioFileOpenWithCallbacks
to open the m4a file is that the api call is failing to open the following file after downloading it locally ( http://www.arsenal-music.com/podcast/arsenal-podcast-05.m4a ). This m4a file has images embedded in it and AudioFileOpenWithCallbacks
is not able to parse the file. At the same time I have used Matt Gallagher AudioStreamer
code that opens this file, parses it and plays it fine. So I am leaning towards using AudioFileStreamerParseBytes
by reading data from a local file. (As far as I understand there should be no difference whether the data is coming from HTTP stream or a local file. But I could be wrong.)
I do not see any errors in the any API calls (just in case someone asks me this question). I can paste the code if needed, but all I want to know is if the approach of reading from file and passing it to AudioFileStreamParseBytes
will work or not ?
After some testing I found that one can use AudioFileStreamParseBytes
to parse bytes that are read from a local file. Data need not come from a Http stream.
