That is amazing that it still can be compiled and interesting to see what it looked like. gg/phyllis On Mon, Mar 9, 2020 at 9:12 PM Andrew Randrianasulu <[email protected]> wrote:

So far it works on IA32 :} (actually, kernel is 64-bit, but all userspace still 32-bit, this may contribute to some crash-on-pause behaviour, if playing audio via aoss)
I think I'll try to make yuvpipe output, and may be try to fix alsa audio ...
Actually, it seems 'floating point alpha' in this version of Broadcast kills perf most :}
2 fps on 1280x720 video if I use fader .... at 1.4Ghz x 4 But still nearly 12 fps for two-track video (1280x720, mjpeg - 75% and 50% faders) if I just use alpha channel and set CPU to max - 3.9 x 4 ghz :}
Thing is, apparently 'bilinear interpolation' uses exactly FP alpha, so it will be SLOW on HDTV sized videos - time to dig into source to see if scaled interpolation can be used with just integer alpha channels
Have nice days {nights}, and good health!
