...ected it would work joining different bitrate/encoding streams, but just then I tested joining an 8000Hz narrowband stream with a 16000 Hz wideband, and the output sounds pretty sane. The interface is: peexcat --title "new title" --author "new author" \ file1.spx start_frame end_frame file2.spx start_frame end_frame ... Ideally, you should be able to specify the time as hours:mins:seconds.splitseconds rather than frame numbers (by bash you can just do $(((min*60+sec)*50)) but it's tacky). I discovered the magic number 50 somewhere as being the number of speex frames per s...

As it turns out, with the proprietary firmware, the VP3 and VP4 interfaces are identical. Furthermore, this is all already implemented for nvc0. So these patches (a) move the easily sharable bits of the nvc0 implementation into the nouveau directory, and then (b) implement the other parts in nv50. The non-shared parts are still largely copies, but there are some differences, not the least of which
