Hugely off, but .. I like to have my own toy video editor :}

Video from yesterday:

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!
