Audio playing but without video
I currently have JWplayer embedded in our app. When the player is played, there's an audio playing but no corresponding video at the same time. The video is encoded through Azure Media Encoder and it's encoded at "H264 Adaptive Bitrate MP4 set 720p." It works fine in the browser, but when it's played on an android device(e.g. a tablet), there's no video.
The weird catch is that the video will play after about a minute(when I press on the Pause button and then resume playing it again).
Here are some of the files that we had embedded(Manifest files, converted from mp4 to this one via encoding):
