For each new MediaCodec should create a new AndroidSurfaceTexture

[vladyslav-arzhanov]

If after the android hw MediaCodec has been initialized we reset the current stream(QAVPlayer::setSource({})) and try to initialize a new one on the same object, we will get a media codec initialization error:

07-06 12:11:07.399 23011 25266 E BufferQueueProducer: [SurfaceTexture-0-23011-0](id:59e300000003,api:3,p:23011,c:23011) connect: already connected (cur=3 req=3) 07-06 12:11:07.399 23011 25266 E SurfaceUtils: Failed to connect to surface 0xbf66e008, err -22 07-06 12:11:07.399 23011 25266 E MediaCodec: nativeWindowConnect returned an error: Invalid argument (-22) 07-06 12:11:07.400 23011 23207 E MediaCodec: configure failed with err 0xffffffea, resetting...

If I understand correctly, this is because we are using the same QAVAndroidSurfaceTexture object
Q_GLOBAL_STATIC(QAVAndroidSurfaceTexture, androidSurfaceTexture);
so we should create a new one for each new QAVHWDevice_MediaCodec object.

Thanks for the contribution.

So after this fix, there is no Failed to connect to surface error?

Yes, when re-initializing the stream on the same object, the error was not reproduced and accordingly the stream also plays validly.
