4.3.5 Configuring tracks

../img/transcoder_track.png

It's a standard gmerlin configuration dialog, which is built dynamically depending on the stream layout of the source and the encoder setup. On the left you see a tree structure of all settings:

General
Sets global settings like basename of the file and an optional subdirectory of the encoding directory, where the file(s) will be written. Note, that the toplevel destination directory is configured globally, not per track.

If you select “postprocess only”, the input file will be sent directly to the postprocessing plugin. Enable this for files, which already have a format supported by the postprocessor.

Finally you can choose to transcode only a certain selection given by the start- and/or end time.

Metadata
Here, any available metadata are imported from the input, and you can edit them. Note that not all medatada fields are supported by all output formats. Some formats don't support metadata at all.
Global encoder options
For each enabled encoding plugin, you can configure global settings here.
Stream options
For each stream, you have Generic options. Here you can en- or disable the stream, set the language and the format. In addition for subtitles, you can choose whether to convert text- to overlay subtitles, blend subtitles onto video frames or encode them separately.

For Audio and video streams, you can also set up filters.

For text subtitles, the render options let you configure the font and colors of the subtitles, if they are converted to overlay subtitles.

The default format of subtitles is for the rare case, that you want to convert subtitles to a video stream. It's only used if you encode subtitles but no corresponding video stream.

The last tree- node for each stream has always the codec option of the output plugin for the respective streams. Here, you can change encoder settings for each stream separately.
