The Dranger tutorial covers it all. http://www.dranger.com/ffmpeg/ But the quick answer is that * time_base is a unit of measurement for which all pts/dts values are based on. So instead of making the pts/dts a count of microseconds, they make it a count of time_base units. Basically they do this to eliminate roundoff errors. * sample_rate is the number of samples per second that should be delivered to your soundcard * channels is the number of independent sound channels, such as "left,right" (2), or "frontleft,frontright,backleft,backright,center,sub" (6) -- Michael Conrad IntelliTree Solutions llc. 513-552-6362 [email protected] _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
