Sometimes only audio is playing , video is black when using in RecyclerView

[usmanrana07]

I've checked previously closed similar issues but the discussion there didn't solve my issue.

The scenario is that I'm creating maximum 3 players to preload the videos. Player is assigned to UI cell when it is at center of screen. So, if user scrolls the recyclerView then urls for next videos are updated in existing players and matching player is set to new centered position. In normal case it is working fine but if I scroll up or down frequently then on view recycling when new content is updated then player shows a blink effect and sometimes completely goes black. The audio plays but video doesn't. If I make the player in playerView null and reassign the same player again. Then it works fine unless it is detached and attached again.

Hard to say what the problem is. From what you are saying I would say that you are running out of HW codec instances for video. Audio is probably decoded with a software decoder so this works.

Your approach with three players seems to sensible to me though. What do you do when you switch from one video to another in the recylerview when scrolling? Do you call stop, release or do you just remove and add media sources?

However, if I'm right with what I am saying regarding codec instances, you should see stack traces in the logs. Do you see something like this?

I don't stop the player. I just set playWhenReady=false and setMediaSource with the next url. There is nothing in logs I've checked that.
