When I try to access the substream with the URL It returns a 1920*1080 resolution image? It should return the substream 640*480 resolution image? what am i not getting right here? ive also tried /Streaming/channels/2/picture?snapShotImageType=JPEG with same result. I can change the channel id to any number and get the same result.
