decodeToBuffer does not fire callback about ogg.js HOT 5 OPEN

Your test.opus file is zero length. Causes #7.

from ogg.js.

I've updated the test to use a larger (~1MiB) test file. It is now using ogg vorbis instead of opus.

Making the code change in #7 fixes the 500 sample opus file, but still no callback for the vorbis.

I get an abort. Looks like an assertion is being triggered somewhere in the vorbis decoder.

I've tracked it down to a segfault in a realloc in ogg_sync_buffer (framing.c:645). It asks for 16 and 23k, then fails on a request for 28k. I'm out of my depth now.

Changing vorbis.js's buffer size to 2048 (instead of 4192) makes the decode succeed, but the audio is shorter than it should be and fairly garbled. I did a bit more fiddling with buffer sizes but most end in an abort(). I don't think I'm on the right track. I will continue to investigate.

Changing framing.c:641 to increase in multiples of 8kiB instead of 4kiB produces correct decodes. This feels like a hacky workaround though. This might be an emscripten bug but I'm hesitant to suggest this because of my lack of knowledge.
