HLS - support manifest with several #EXT-X-MAP tags

Have you read the FAQ and checked for duplicate open issues?
Yes

Is your feature request related to a problem? Please describe.
All our content has program segments and each program segment starts with a different init file. One of the primary reason to have multiple EXT-X-MAP tags.

Describe the solution you'd like

Describe alternatives you've considered
Dash version does work but won't be able to use dash manifest in our workflows.

Additional context
Will send sample streams with multiple #EXT-X-MAP tags via email.

This isn't about having multiple EXT-X-MAP tags, but because you use EXT-X-DISCONTINUITY, which we don't support. See #1335.

Hello @ppatlolla-turner ,

I tested with your sample file, however it looks like it doesn't have multiple EXT-X-MAP tags, and I didn't see any error message. Could you please send us another file that has multiple EXT-X-MAP tags? Thanks!

[ppatlolla-turner]

Are you testing HLS version or DASH version? DASH should work fine.
There should be 6 EXT-X-MAP tags.
#EXT-X-MAP:URI="_169610_0_0.mp4"
#EXT-X-MAP:URI="_169610_0_1.mp4"
#EXT-X-MAP:URI="_169610_0_2.mp4"
#EXT-X-MAP:URI="_169610_0_3.mp4"
#EXT-X-MAP:URI="_169610_0_4.mp4"
#EXT-X-MAP:URI="_169610_0_5.mp4"

Got it. Thanks!

This will be fixed as part of our discontinuity work.

Hello @ppatlolla-turner ,

This code change is on our latest nightly build https://nightly-dot-shaka-player-demo.appspot.com/ .
However, we're seeing "Shaka Error DRM.LICENSE_REQUEST_FAILED" error on our demo app.
Could you please test again with your manifest, and let us know if it works?
Thank you!

Hi @michellezhuogg
I was able to play the multi_init segment stream using the above player.

Just emailed the url's in a text file. Please try and confirm.

If it still doesn't work I need to check if geo-location is turned on. Are you checking form outside US?
Thanks

[ppatlolla-turner]

Sorry I was too fast. Stream wouldn't continue playing after the first program segment.
Earlier playback wouldn't even start.
Thanks

[michellezhuogg]

Thank you! Verified that the video can play until 3:25, keeps buffering for more than 5 secs before it continues to play. Similar for earlier playback.

[ppatlolla-turner]

Yes it continues it play after 3:25 but only after a long period off buffering.
