I'm trying to stream some URLs to my Chromecast through a sender app. They're HLS/m3u8 URLs.
Here's one such example URL: https://qa-apache-php7.dev.kaltura.com/p/1091/sp/109100/playManifest/entryId/0_wifqaipd/protocol/https/format/applehttp/flavorIds/0_h65mfj7f,0_3flmvnwc,0_m131krws,0_5407xm9j/a.m3u8
However they never seem to load on the Chromecast, despite other HLS/m3u8 URLs working (example of an HLS stream that does work).
It's not related to CORS as they indeed have the proper CORS headers.
I notice they have separate audio groups in the root HLS manifest file.
When I hook it up to a custom receiver app, I get the following logs:
The relevant bits being (I think): Neither ID3 nor ADTS header was found at 0 and cast.player.api.ErrorCode.NETWORK/315 (which I believe is a result of the first)
These are perfectly valid/working HLS URLs. They play back in Safari on iOS and desktop perfectly, as well as VLC.
Is there something I need to be doing (either in my sender app or my receiver app) to enable something like the audio tracks? The docs seem to indicate something about that.
I also found this Google issue where a person had a similar issue, but solved it somehow that I can't understand. https://issuetracker.google.com/u/1/issues/112277373
How would I playback this URL on Chromecast properly? Am I to do something in code?
