Okay, so I have audio/video capture working with this brooktree driver on
*bsd. If I capture just straight video I cn capture to disk w/ 384x288 at 25fps
divx with no frame loss, no issues. At 768x576 I can get about 24fps to disk
if I do -ovc copy.
This is great. However, If I enable audio capturing, the performance goes
into the toilet. I can only get 2-5fps, I see DEMUXER errors (that I dont
really understand), and I get all sorts of headaches. This happens with lame
encoding, as well as -oac copy and -oac pcm. This tells me there is something
"Wrong" in the stream handling code. Anyone have any ideas/suggestions?
These tests are all with -mc 0, without that flag is just doesnt work at all.
