Hi all,</font>
<br>
<br><font size=2 face="sans-serif">I tried to use mplayer to play back a test.mov on Linux and have the following problems:</font>
<br>
<br><font size=2 face="sans-serif">1. the test.mov is composed by one AAC audio and MPEG-4 video, the video can be decoded, but for the audio, it reports:</font>
<br><font size=2 face="sans-serif">--------------</font>
<br><font size=2 face="sans-serif">MOV track #0: 483 chunks, 483 samples</font>
<br><font size=2 face="sans-serif">Audio bits: 16 chans: 1 rate: 44100</font>
<br><font size=2 face="sans-serif">Audio extra header: len=97 fcc=0x77617665</font>
<br><font size=2 face="sans-serif">Fourcc: mp4a</font>
<br><font size=2 face="sans-serif">--------------</font>
<br>
<br><font size=2 face="sans-serif">..................</font>
<br><font size=2 face="sans-serif">==========================================================================</font>
<br><font size=2 face="sans-serif">Opening audio decoder: [faad] AAC (MPEG2/4 Advanced Audio Coding)</font>
<br><font size=2 face="sans-serif">ADecoder init failed :(</font>
<br><font size=2 face="sans-serif">*** Try to upgrade /root/.mplayer/codecs.conf from etc/codecs.conf</font>
<br><font size=2 face="sans-serif">*** If it still does not work, read DOCS/codecs.html!</font>
<br>
<br><font size=2 face="sans-serif">The FAAD is working, and can decode other mp4 files containing AAC track. And I use the QT Pro to export MOV to MP4, by choosing "Pass through", then the new test.mp4 can be played by mplayer. </font>
<br>
<br><font size=2 face="sans-serif">2. I tried to use -dumpaudio and -dumpvideo to get the raw tracks of video and audio, and add them to a mp4 file with mpeg4ip tools. But I failed with the audio track again. Only the video is correctly added. And that audio track is quite different from the audio track extracted from test.mp4 generated as above, while the video tracks are the same.</font>
<br>
<br><font size=2 face="sans-serif">So the problem lies in the format of test.mov or the player? </font>
<br>
<br><font size=2 face="sans-serif">Thank you for any hints. </font>
