I have a MediaPlayer
rendering videos to a TextureView
. This is working.
Now, I want to display a still image on this TextureView
for a given time, then get the MediaPlayer
to render a video to the same TextureView
.
Here's my code to render the bitmap:
Canvas canvas = mTextureView.lockCanvas();
canvas.drawBitmap(sourceBitmap, matrix, new Paint());
mTextureView.unlockCanvasAndPost(canvas);
After this, any attempts to play videos result in ERROR_INVALID_OPERATION
(-38) being triggered from the video player.
I tried commenting out the call to drawBitmap
, and the error still happened. It seems that the simple act of calling lockCanvas
followed by unlockCanvasAndPost
results in the TextureView
being unsuitable for the MediaPlayer
to use.
Is there some way that I can reset the TextureView
to a state that allows the MediaPlayer
to use it?
I'm working on Android 4.2.2.
