No, it isn't that simple: ac3_sync is given a buffer, which has only header_size bytes. So it isn't able to read headers of following frames and it doesn't know if they're an extension of current frame.... -- Bartlomiej Wolowiec _______________________________________________ FFmpeg-soc mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc
