Hugely off, but .. I like to have my own toy video editor :} https://github.com/Randrianasulu/broadcast2000/commits/master
Video from yesterday: https://www.youtube.com/watch?v=j1xvaWXEXzA 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! -- Cin mailing list [email protected] https://lists.cinelerra-gg.org/mailman/listinfo/cin
