Issue
When loading http://static.france24.com/live/F24_EN_LO_HLS/live_web.m3u8 using Flutter’s videoplayer the app crashes, but if I load https://flutter.github.io/assets-for-api-docs/assets/videos/bee.mp4 it does not crash.. When it crashes it gives the following error:

And in my pubspec.yaml I have video_player: ^0.10.11+2.
Can you help me figure out what’s going on?
Solution
basically the solution is to add an android dependency that’s opt-in for exoplayer. Either you or the lib author should do it.
At this moment I’m not sure if it’s you or them inserting ads (In-Media-Advertising? sic), or if there’s some sort of video_player_ima dependency out there.
A quick fix for you is add this to android/app/build.gradle in the dependencies section. But it should really be done in either video_player or a more appropriate lib.
implementation("com.google.android.exoplayer:extension-ima:<insert version here>")
make sure to match version, get a peek at the other exoplayer deps with
cd android
./gradlew :app:dependencies
Edit: Seems like exoplayer eliminated the class AdsMediaSource$MediaSourceFactory between version 2.10 and 2.11.
Talking in private with @joao it’s not clear how he solved the problem. But it came from the fact that he was using both flutter plugin video_player with a dependency to exoplayer 2.9 and media_info with a dependency to 2.11.
Cross referencing the issue I opened on exoplayer to fix this cleanly https://github.com/google/ExoPlayer/issues/7638
Edit2:
After some investigation, it’s confirmed that for the reasons in edit1, you shouldn’t have exoplayer mixed versions. From issue 7638:
If you see gradle dependency resolution doing something like this com.google.android.exoplayer:exoplayer-core:2.9.6 -> 2.11.5 (*) then there is a risk things won’t work.
Edit3:
We got official answer from exoplayer team recommending pinning down the version each flutter plugin uses. The expectation is that it will fail at compile time.
