Yeah, I'm replying to the same thing twice. Sue me. Anyway, both start with RIFF. Apparently avi2wav thinks it's extracting a wav so puts the wav header on it. So I tested it. Made 2 short clips of AVI, one with PCM audio and one with MP3 audio. Extracted both with avi2wav. Both had similar headers: WAV: RIFF~²' WAVEfmt D¬ ± dataX²' MP3: RIFF‚Ÿ WAVEfmt U "V X ¶ qdataPŸ (In hex of course...this is just what I got in notepad cause I don't have a hex editor). Then I used LAME on both, and the wav of course gave me a good mp3 but the MP3 with wav header( and file extension) gave me crap. So, reading the header won't work. Also, it is apparently an mp3 wrapped in a wav. Why avi2wav does this is beyond me. ---------------------------- New version up though, same location. Now with automatic resizing goodness via AVISynth. This means you also have to download AVISynth, but only if you want the resizing. So don't click resize if you don't have AVISynth. _______________________________________________ http://cool.haxx.se/mailman/listinfo/rockbox Received on 2004-02-20 Page template was last modified "Tue Sep 7 00:00:02 2021" The Rockbox Crew -- Privacy Policy |
