No. In MLT, a frame is, by definition, uncompressed. You could write a producer that performs all 4 steps above. What is your *end goal* such that you need MLT? If all you want to do is play the video on the screen, you can do that by hacking ffmpeg directly - no need for MLT. ~Brian ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
