Playback hangs with v2, worked fine with v1

[abhishekjain89]

Exoplayer (v2.0.0) playback hangs on short videos (<10seconds). The renderer is stuck in buffering state while the extractor has reached end of input. Happens near the end of the file. This worked fine with v1.

Here is a file that you can repro with. The file was generated on Nexus 5 (6.0.1). I added this to the demo app's media.exolist.json file to repro:
file download link: https://dl.dropboxusercontent.com/s/8wzp8mz0dz1x7cs/exoplayer_test_file.mp4?dl=0

You will notice that the playback hangs (ends?) between 00:02 and 00:03. The playback state is stuck on BUFFERING.

I have same problem and found that
In my case when recording video and audio not synced
audio delay 500ms
But I can not fix that
Sorry my bad English

[ojw28]

We'll provide a fix for this shortly. It's unclear whether the second issue is the same, however.

Thanks @ojw28, would you be able to share an estimate date for the patch?

[ojw28]

Tomorrow.
