Exoplayer: ImaAdsLoader doesn't work with HLS content that uses EXT-X-PROGRAM-DATE-TIME

[priscila225]

I'm running the demo app for v2.6.1 and I hardcoded it to play this HLS video: https://content.uplynk.com/babd2bd748ee47c48e0fb6b492245eb9.m3u8

I'm trying to use this google sample vmap: "VMAP - Pre-roll Single Ad, Mid-roll Standard Pod with 3 ads, Post-roll Single Ad"

When the playback starts I see that the prerolls doesn't play, instead I get the 3 midrolls where the preroll should be. Also I can't see the post-roll ad working, it just keeps loading forever.

The content media source has a window that is offset from zero, while the ad group times start from zero. This is not handled correctly in Timeline at the moment, which leads to the player identifying the wrong ad group to play.

We have a fix in review which will treat ad group times as relative to the window in Timeline (ImaAdsLoader already makes this assumption), so hopefully this will be fixed on the development branch soon.

I think the new plan is to adjust HlsMediaSource so that the Timeline window and period are aligned for this type of media.

@andrewlewis @ojw28 sounds good, let me know when you have a fix on HlsMediaSource to test it. Thank you!

[andrewlewis]

@priscila225 This should be fixed on the development branch. Please try it out and let us know if there are any further issues.

@andrewlewis this is working fine for us. Thank you a lot! I confirmed using the sample with m3u8 links as well. Also the plan to have it on release, you have a date?

Just to know if we will wait too much to have the fix on final release.
I'll work for now with dev version! awesome

Thank you!

The fix will land in 2.7.1 which will likely be released this week or early next week.
