mencoder, transcode, ffmpeg The thing to remember is that the file extensions you see on most videos (.avi, .mov, .ogg, etc.) are indicators of their container formats and are not reflective of the codecs used within. The container multiplexes a few data streams, most commonly an audio and a video track. You could also have other tracks to cover subtitles, closed captions, translations, commentary, and so on. So what you ought to be examining is the audio and the video format used within the container. A lot of stuff you find on the Internet contain DivX or XviD video with MP3 audio. You can get better audio quality/compression if you used Vorbis instead. If audio isn't important, you could cut out that stream altogether. -- Bring choice back to your computer. http://www.linux.org.au/linux -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
