but does this memory usage increase with each loaded clip/media, or stay the same? does memory actually leak (usage grow, and some memory still not freed after program quit)?
18% sounds a lot (too much for single-frame decoding i was hoping for)
Yes, it gradually increases with each loaded clip/media. The memory is freed after the program quits.
I even tried this line in ffmpeg.C instead as a really wild guess: av_frame_free(&probe_frame);
For now, leaving the ff->video_probe(1); line commented out. Someday we can get back to it.
Do not worry about it -- something will pop up later. ...Phyllis
