The dynamic resoltuion change occurs when he decoder detects a coded
frame with one or more of the following parameters different from those
previously established (and reflected by corresponding queries):
1. coded resolution (OUTPUT width and height)
2. visible resolution (selection rectangles)
3. the minimum number of buffers needed for decoding
4. bit-depth of the bitstream has been changed
when the bit-depth is changed, the pixel format will be changed,
so the format is changed after a source change event,
we should handle it and reinit the capture queue.
