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
