[FFmpeg-user] Slideshow+audio causes huge amount of memory allocated
hello, the following command line plays a web radio while showing a picture slide show. ffmpeg -loop 1 -framerate 1/10 -i img%3d.png -i http://webradio:port -vcodec rawvideo -pix_fmt yuv420p -vf fps=fps=25 -acodec pcm_s16le -ac 2 -af aresample=48000:first_pts=0,asetnsamples=n=1920:p=1 -f asf - | ffplay - The longer is the time between pictures, the bigger is the memory allocated (> 1gb). I suppose this is caused by fps filter that every 10 seconds generates 250 frames and the multiplexer, trying to keep proper interleaving, buffers a lot of frames. Can you suggest some alternative that allow me to do this in realtime? (the script should run 24/7) thanks, MB ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user

[FFmpeg-user] How to create trapezoid videos with ffmpeg?
Hi: New to ffmpeg. How can one create a trapezoid shaped video as a overlay to the background as seen at http://www.youtube.com/watch?v=_380o5B9MrA (starts at 00:02:25) using ffmpeg command?
