Hi! I’m wondering what’s MLT requirement when it comes to producer’s supplied mlt_frame_get_image() and mlt_frame_get_audio() functions. Should they always work? Let me explain what I mean by that…
In my producer I’m using a library which produces data asynchronously for a media file, and puts it into main memory (e.g. on heap). Basically what I get from the library is raw audio/image data stream of „in-sequence” frames. I’m moving this data to caches, from which my producer’s mlt_frame_get_image() and mlt_frame_get_audio() read data when it becomes available. So let’s say consumer requested frames for mlt_positions in that sequence: 1 2 3 4 10 11 12 13 18 19 20 5 6 7 8 The questions are: Do I have a guarantee that consumer will get frames get_image() and get_audio() in that exactly sequence also? Can consumer call get_image(), get_audio() multiple times? I’m asking because my producer’s design assumes that get_image() and get_audio() will be called in exactly that sequence, and exactly once [that is, when consumer calls get_frame(), I assume it will call get_image() and get_audio() somewhere in the future, but before next frame’s get_image() and get_audio() and it will do it exactly once] and I’m wondering whether the assumption is correct… (because if it isn’t, I may be in situation where data requested by MLT will never be in my cache again and I have a deadlock, so probably will need to redesign few things) Best, Paweł ------------------------------------------------------------------------------ Attend Shape: An AT&T Tech Expo July 15-16.
