Martyn Ranyard talked about video in Linux. The main points were:
For YouTube and others, use Video DownloadHelper for Firefox; this also has a conversion option but won’t download certain videos.
WinFF will convert most formats including iPhone.
mencoder input_file -ovc codec -oac codec -o output_file where using
copy instead of
codec simply places the file in a different container.
mencoder file -ovc help lists the available codecs.
Use firewire to download videos from video cameras and Kino [no longer being developed] for capture and editing.
’Q’ DVD Author allows you to create DVD menus.
Most webcams will work with either Video4Linux or Video4Linux2; n.b. not all webcams know about the other version and they are subject to frequent changes of chip; so different examples of the same model may not work with the same software.
Use Cheese as the GUI interface for a webcam.
Alternatively mebeam.com [defunct] used flash video instead to transfer the signals.
Use mencoder to convert from flash.
