[NUT-devel] fourcc for raw PCM data?

According to the spec, the fourcc for raw PCM data would be the same as in .avi, i.e., 0x0001. However, this fourcc does not specify how many bits the samples have. Raw PCM does not seem to have any codec specific data that could be used for this purpose. Should I use one of the .mov fourccs instead? Regards, Clemens
