I've committed a fix to FMJ for this problem. It seems that I don't know how to correctly calculate the frame time for a given frame based on the pts/dts in the packets that make up the frames. So I changed it to just use the frame number and frame rate for now. The movie plays with this changed. Committed to CVS, the patch is attached as well. Also, for troubleshooting purposes, I've now added a simple standalone player to ffmpeg-java, see my news posting below. Ken ----------------- For testing, ffmpeg-java now includes a simple video player that does not use JMF/FMJ. It is very simple for now, does not have correct timing or sound, but it is a start. Get the latest ffmpeg-java release, and try something like; java -cp ./ffmpeg-java.jar:./lib/jna.jar net.sf.ffmpeg_java.example.PlayerExample http://www.javasaver.com/testjs/jmf/anim/2005-11-26.mov Brent Baccala wrote: > On Tue, 28 Aug 2007, Ken Larson wrote: > >> Did you increase your OS swap space, or increase the amount of memory >> available to ant?
