Detailed Description
The following functions are required to be implemented for all decoders that advertise the VPX_CODEC_CAP_PUT_SLICE capability. Calling these functions for codecs that don't advertise this capability will result in an error code being returned, usually VPX_CODEC_ERROR

put slice callback prototype
This callback is invoked by the decoder to notify the application of the availability of partially decoded image data. The
