Support more formats in the Ogg container (e.g. Theora)

[Yourbadman]

movie.ogg.zip

Can't play this ogg file. OggExtrator.sniffInternal will return false, so none of the available extrators.

OggExtrator.java
if (!header.populate(input, true) || (header.type & 0x02) != 0x02) {
return false;
}
will be return false;

but i can play this ogg file in Android MediaPlayer.

That's not what happens. It's returning false further down:

    if (FlacReader.verifyBitstreamType(resetPosition(scratch))) {
      streamReader = new FlacReader();
    } else if (VorbisReader.verifyBitstreamType(resetPosition(scratch))) {
      streamReader = new VorbisReader();
    } else if (OpusReader.verifyBitstreamType(resetPosition(scratch))) {
      streamReader = new OpusReader();
    } else {
      return false;                                              <---------- here
    }

This is because we only support Vorbis, Opus and Flac inside the OGG (see our supported formats page). Where-as I think this particular file contains Theora video. Marking as an enhancement, but I doubt this will considered high priority.

Hi, are there any chances to add Theora support?

[EchedelleLR]

I am also interested in Ogg Theora support.
