Text output formats
|
||
|
|
===================
|
||
|
|
|
||
|
|
Shaka Packager supports several text/subtitle formats for both input and output.
|
||
|
|
We only support certain formats for output, other formats are converted to the
|
||
|
|
specified output format. With the exception of TTML pass-through, there are no
|
||
|
|
restrictions of input vs output formats.

Examples
|
||
|
|
--------
|
||
|
|
|
||
|
|
* TTML pass-through::
|

$ packager in=input.ttml,stream=text,output=output.ttml
|
||
|
|
|
||
|
|
* Convert WebVTT to TTML::
|
||
|
|

|
|

|
|
* Embed WebVTT in MP4 (single-file)::
|
||
