Hi all, I succeeded in creating a preview of the unfiltered frames, as suggested by Dan: I wrote a filter, first in the chain, which extracts the image.
Now I have another problem: I would like to process frames to inspect the audio levels. I thought I can use the audiolevel filter and ask it to process every single frame. I make a loop for every frame I am interested in, call mlt_service_get_frame(...), then call mlt_filter_process(audiolevel, frame). It works, but only if I make a call to sleep(). It seems to me, that it works only because the consumer, because the sleep(), has a chance to request the final frame to display, and doing so all the filters are run. Is there a way I can get frame by frame, and run on them only the filters I want, without using a consumer? Thank you, linuxfan _______________________________________________ Mlt-devel mailing list Mlt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/mlt-devel
