MIME types are case-insensitive, but none of the many existing comparisons across our code base take this into account. The code can be made more robust by normalizing all MIME types at the moment they are first set into a class/builder and adding toLowerCase as part of the normalization. Most concretely, this fixes an issue with playing HLS streams via the IMA SDK where the stream MIME type is indicated with all lower case "application/x-mpegurl", which failed the MIME type comparison in DefaultMediaSourceFactory.

Transformer module
Provides functionality for transforming media files.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-transformer:1.X.X'
where 1.X.X
is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
