  • The option -an disables audio recording, -f forces the use of video4linux for the input, -s sets the video to the size 320x240, -b sets the recording bitrate, -r sets the frame rate to 15fps, -i gives the input device, -vcodec sets the output format. Press Q to stop recording or you can specify the recording time with the -t option like -t 00:1:30

  • Very useful for recording radio scanner for instance as the resulting audio file contains only audio signal that exceeds -45dB and the file name tells you when the recording was done. Why waste time listening silence? ;) Show Sample Output

  • This command will transcode a MythTV recording. The target device is a Google Nexus One mobile phone. My recordings are from a HDHomerun with Over The Air content. Plays back nicely on the N1.

  • Here's the other way of doing it in vim: setting a recursive macro. 'gg' brings you to the top of the buffer, 'qqq' clears the 'q' macro, 'qq' starts recording a macro called 'q', '/^$' moves the cursor to the next empty line, 'dd' deletes the line that the cursor is on, '@q' calls the 'q' macro (currently empty because of 'qqq'), and 'q' stops recording the macro. '@q' calls the macro. It will run until it cannot find another blank line, at which point it will throw up an error and cease. While this is longer than the regex, you can use it without having to move your thoughts from 'vim-mode' to 'regex-mode'.
