Or at least it do on my machine (i586 Slackware)
of course format support very limited, like mjpeg/dv/yuv/rgb for quicktime video, no mp3 or vorbis or mpeg4...
But it seems to work and even recording from screen!
Speed is nothing to write home about - may be 6-8 fps for 1920x1080p mjpeg and fade + brightness plugins set on video track.
Audio also may not work (I tried to use aoss, you can change it to padsp or something if you run pulseaudio)
Main hazard was missing returns in many, many functions - without them I only was able to run bcast2000 without any optimizations when compiled with gcc 11.2. Now I added A LOT of those 'return 0' (hopefully in right places!) and optimized build seems to work!
Still might crash with ffmpeg's default yuv444/yuv422 mjpegs - but it works if you set - pix_fmt to yuv420. mpeg files require manual TOC creations - watch out terminal output.
I think after visiting every single in 51 plugins I appreciate much more amount of work put into this ancient program!
