DESTINATION can be a file which is then created or a directory. In the second case, a file with the same name as the source file but with the destination format's extension is created. OPTIONS -h, -help A help text is displayed. -v, -verbose Verbose mode. Commands are printed to STDOUT before they are executed. -vv, -debug Debug mode. Same as -v, but command output is also printed. -i, -info Information mode. Only information about the source given is printed. -y, -overwrite Existing destination files are overwritten. Use with caution! -n, -skip Already existing destination files are not converted. -d, -tmpdir This option specifies a directory where temporary files are stored. -f, -force Force conversion of all audio and video streams. -fa, -force-audio Force conversion of all audio streams. -fv, -force-video Force conversion of all video streams. -ng, -nogain Skip normalization of audio streams. -p, -profile Specifies a quality profile. Available profiles are: worse, bad, normal, good, best. -t, -target Specifies a target device. Available targets are: phone. EXAMPLES Convert a video file to mp4. conv2mp4pl /home/you/videos/example.avi In this case a file named /home/you/videos/example.mp4 is created. Convert a file to mp4, but don't copy streams. conv2mp4pl -f /home/you/videos/example.avi Same like above, but don't copy streams as they are. Convert a video for your mobile. conv2mp4pl -p bad -t mobile /home/you/videos/example.avi /media/mobile/videos/ This creates a file named /media/mobile/videos/example.mp4 with the desired quality level. Convert many files at once. find /home/you/videos/old -name *.avi -exec conv2mp4pl -n "{}" /home/you/videos/new \; This command looks for avi files in the /home/you/videos/old directory and starts an instance of conv2mp4pl for each of them. |
