I tried to play a video file on Android, and failed miserably.
webm - either video doesn't show at all, or it freezes. Tried both VP8 and VP9, with or without audio track
ogv - stutters, apparently uses too much CPU, even if bitrate/fps/resolution are low
OS.native-video-play() - no documentation, no error dump, and didn't play the video file
VideoStreamGDNative/godot-videodecoder - couldn't get from the documentation how to use it nor what it is capable of doing.
Anyone ever succeeded in playing a video on Android, and can share what their success story?
