Hi, I've read in the apiexample these lines about decoding section: /* NOTE1: some codecs are stream based (mpegvideo, mpegaudio) and this is the only method to use them because you cannot know the compressed data size before analysing it. BUT some other codecs (msmpeg4, mpeg4) are inherently frame based, so you must call them with all the data for one frame exactly. You must also initialize 'width' and 'height' before initializing them. */ What this would mean?I want to capture screenshots from desktop, encode these images with mpeg4 and then send to a remote client, then to decode I think that I'm forced to send some information about every frame. Is this right? Regards. -- Riccardo Corona
