transcode / Import Modules


The -x flag.
Import modules deal directly with the mediafile you give on the commandline. Usually, transcode can detect the codecs used in your mediafile automatically. This means that you don't even have to specify the -x flag.
If the detection doesn't work, or if you want to do something specific with your file, you should add commandline options to the -x flag.
If you don't know what kind of codecs are being used in your mediafile, you can use 'tcprobe -i yourfile' to figure it out. After that, you can read through the specific module page to see what options transcode gives you.

tcprobe uses the same code that transcode uses to inspect mediafiles. Many types of mediafiles are not correctly analyzed by transcode or tcprobe. Mediafiles that are not analyzed correctly can be analyzed using mplayer like this:

mplayer -vo null -ao null -frames 0 -identify $mediafile
