4.3.2 Quick intro

Gmerlin transoder can transcode every supported input file to any of the supported output files. It has some unique features, which seperate it from other transcoding applications. Most notably:

Per stream settings
All settings are configured for each stream separately. This means, different streams can have different formats, different filters and even different codecs (of course only if the container supports it)
Subtitle support
There are plugins for exporting subitles to separate files or to the same file, where the A/V data gets written. Alternatively, you can blend subtitles onto the video frames (for containers, which don't support subtitles).
Profile support
Finding out the right encoder parameters can be a time-consuming task. gmerlin_transcoder allows you to save all settings and load them later. Once you have found out your favourite encoder settings for a specific task, transcoding is a matter of
Postprocessing support
There are postprocessors, which take the encoded files and make e.g. Audio CDs (with cdtext) from it. It also contains a frontend for cdrdao, so you can burn them as well.
Chapter support
gmerlin_transcoder imports all chapter seekpoints from the source, and writes them into the file (currently only supported for Quicktime and mp4). You can also edit chapter lists or create new ones
Language codes
gmerlin_transcoder lets you import, edit and export language codes for the Audio- and subtitle streams
2 Pass encoding
For plugins, which support it, we can do 2-transcoding. There is also a generic volume normalizer built in.

There is a tasklist, in which the tracks are queued. All newly loaded tracks get the globally configured settings (plugins, formats, filters). You can then fine-tune the tracks by configuring them individually. Changing track parameters for multiple tracks at once isn't possible. Instead, make the settings, save them to a profile and load the profile before loading the tracks.
