Low priority.

Any update? How can I choose video streams from TS?

@osztrovszky That is not a multi-program stream and it is already supported. See https://google.github.io/shaka-packager/html/documentation.html#stream-descriptors. You can use a number based stream selector, i.e. 0, 1, 2, 3.

Hello there,

Any update on supporting Multi-program MPEG2-TS stream(s)? To present (and to my knowledge), shaka-packager does not implement this yet, resulting in this error when attempting to package this type of content:

ERROR:ts_section_pat.cc(90)] Multiple programs detected in the Mpeg2 TS stream
