Thank you very much! It's exactly what I need. But it works only partially, I mean, I'm able to play the movie file directly from the buffer but I am not able to seek. I've implemented the seek function but it doesn't work as expected. As I seek, the seek callback function is correctly called with SEEK_SET as whence but it behaves in a strange way. I try to explain this clearly: seek function is called with the required file position to seek to, then I seek into my buffer to reach the required position and return the new position after seek. Remember that my buffer is an exact 1:1 copy byte by byte of the entire file, so seeking to a certain position in a file is equal to seeking to that position in my buffer. After seek callback function has returned, it gets called once again with SEEK_SET as whence and with a negative offset, therefore I am supposed to seek to a negative position in my file/buffer. This obviously makes seek function to return -1 and therefore also av_seek_frame returns -1 and this is interpreted as end-of-file. Where is the mistake? I don't know if this is important or not, but my buffer is a copy of a m2ts file which contains: video (h264), audio (DTS and AC3) and subtitles (PGS). _______________________________________________ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
