Include the following:

• ExoMedia version: 2.5.5
• Device OS version: 6.0
• Devide Manufacturer: Samsung

Reproduction Steps

Start a remote stream, especially on a slow or low bandwidth (cell) connection.

Expected Result

Starts playing

Actual Result

Buffers indefinitely, may eventually play.

Reference:
google/ExoPlayer#1285

It seems your library either needs to set minRebufferMs to 0 or expose it so we can manipulate it to work around the ExoPlayer issue.

Currently it is expected that the media won't play until you get some amount of media to play. In your case where it will sometimes play to me this means that you just need to wait (and it isn't actually in Buffering indefinitely). As such, the ability to override player = ExoPlayer.Factory.newInstance(RENDER_COUNT, BUFFER_LENGTH_MIN, REBUFFER_LENGTH_MIN); or specify the REBUFFER_LENGTH_MIN will be a future feature

Of course...

However it's impossible to know the difference between, just wait, and never starts. The instances where we just waiting works, is on the order of minutes, sometimes tens of minutes, Most users just bail and fail into the never starts complaint.

So, I'll have to fork and mod it myself until it gets fixed, by either you or ExoPlayer.

But at least you know about it now.
