In my example, samples per channel actually is the same as samples_pf_pc, this is just the second value in cook's extradata. so samples_pf_pc = 1024. output size in bytes from the decoder (datasize) for one frame then should be 8K (assuming 4 bytes/sample), which is your equation : > (sample_per_channel*no_of_channel*sizeof(sample). > > -- MTReceived on 2010-06-22 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
