Details
To separate from bug 977438, it is different topic. Since there are some use cases using one more video codec instances on the devices with multi-instance codec supported, a resource management is required. 1. Need to consider encoder as well, since most the HW codec resource are shared with encoder and decoder. 2. How to handle currently-used codec instances Assuming the device supports multi-instance, one instance is used in the background and another is used in the foreground. How to balance the resource to let user have a better user experience? Sometimes background user may occupy too much resource and impact the foreground. The possible use case is there is a transcoding/encoding in the background and a video playback is running in the foreground.

For good user experience, it would be better to let the foreground users have sufficient resource. In this case, a possible solution is to let the speed of background decoding/encoding slow or even paused.

Hi Michael, Do you know is there any way to know where we can know/read how many instances supported?

If no, I think we can set the number of instances in Media_Codecs.xml. How do you think?
