Paul -- hey great, this is a good start for me. So if I am understanding you correctly: *** Channel layout 1) Planar channel 1 = data[0] channel 2 = data[channel 1 data length] ...etc. 2) Interleaved channel 1, sample 1 = data[0] channel 2, sample 1 = data[channel 1 sample length] ...etc. Follow up question -- if I have 2 channels in play, is there a 1:1 relationship between channel 1 and channel 2 samples? In other words, for every channel 1 sample will there be a channel 2 sample? (Obviously effects buffer lengths and interleaving). If this is so....perhaps you can expound a little more on how AV_SAMPLE_FMT_S16 is laid out (think I know, just want to confirm). Thx for your help....
