What to do when there's a problem with ad source?

[grajzer]

If there's a problem with ad, player just won't do anything. How to deal with this situation?

Here's an example ad tag URL you can use in exoplayer demo-ima app:
"https://vid.springserve.com/vast/183355?w=400&h=300&url=com.google&cb=1233445"

onAdLoadError is called and the following error is fired "AdErrorCode [name: VAST_LINEAR_ASSET_MISMATCH, number: 403], message: Linear assets were found in the VAST ad response, but none of them matched the video player's capabilities."

Exoplayer should continue playing the video in cases like this.

We expect a 403 and no ad to play but the video content does not play and the player hangs. For testing you can use the following VAST tag.
