I have updated the code above with the changes I made in my project to make it work for local TTML files.
// TEXT RENDERER
// FrameworkSampleSource textSource = new FrameworkSampleSource(context, textUri, null, 1);
// Replaced FrameworkSampleSource with ByteArraySampleSource.
// See this gist:
// https://gist.github.com/anotherhale/878c2d87e6347973ef31
ByteArraySampleSource textSource = new ByteArraySampleSource(context, textUri, null, 1);

are you able to get closed caption working this way? I am getting this error. It seems we can't just pass a non-media url to MediaExtractor's setDataSource, in my case, it's a dfxp file on a remote server.
Internal track renderer error.
