I wonder which it is. i'm noture what you're saying. the video file contains an aac audio stream: % midentify 7085_13_1229065288.m4v ID_VIDEO_ID=0 ID_AUDIO_ID=1 ID_FILENAME=7085_13_1229065288.m4v ID_DEMUXER=lavfpref ID_VIDEO_FORMAT=avc1 ID_VIDEO_BITRATE=0 ID_VIDEO_WIDTH=960 ID_VIDEO_HEIGHT=540 ID_VIDEO_FPS=29.970 ID_VIDEO_ASPECT=0.0000 ID_AUDIO_FORMAT=255 ID_AUDIO_BITRATE=0 ID_AUDIO_RATE=44100 ID_AUDIO_NCH=2 ID_LENGTH=157.48 ID_SEEKABLE=1 ID_CHAPTERS=0 ID_VIDEO_CODEC=ffh264 ID_AUDIO_BITRATE=128000 ID_AUDIO_RATE=44100 ID_AUDIO_NCH=2 ID_AUDIO_CODEC=faad I wanto get that stream in either an MPEG transport stream or an .mp4 fileo I can remux it with a different video stream using MP4Box. mplayer -dumpaudio -dumpfile 7085.dump 7085_13_1229065288.m4v Gives me file with no recognizable container. Iried mencoder with -oac copy but I couldn't get anything but an .avi file. -jsd- Fromashkae at tigershaunt.com Sat Dec 13 02:07:22 2008 From:ashkae at tigershaunt.com (Rashkae) Date: Fri, 12 Dec 2008 20:07:22 -0500 Subject: Extract AAC from video file?
