I'm implementing a FLAC decoder from scratch (save OGG stuff if I can help it) because libFLAC simply will not fit my embedded platform, For the most part I'm implementing using just the documentation but not all of the documentation is concise (especially about variable sized fields) and after looking at the libFLAC source I find myself befuddled so I thought it best to get the information from the people who know these things. So...
In "FRAME_HEADER" there is a field of a variable size field with the description "if(variable blocksize) \n <8-56> : 'UTF-8' coded sample number (decoded number is 36 bits)" and I find the encoding scheme is somehow alien (I can't figure out what it has to do with UTF-8) and it's two following fields to be incomprehensible. There doesn't seem to be any information indicating their purpose either. The location and coding of audio samples is very nebulous in that I don't know where they are or the specifics of how any of their encoding scheme work. More details, links to more information and maybe even some pseudo code would be very helpful. The documentation about the metadata is great... but it kinda goes downhill after that. It would be fantastic if someone could update the documentation with more information and details. Just a side note, the code seems to be written as if it were intended to be written in C++ (even to comments talk about it as if it were), so why not just make it C++ and put a C frontend on it? -Gravis _______________________________________________ flac-dev mailing list [email protected] http://lists.xiph.org/mailman/listinfo/flac-dev
