Echo Spot [2.5" screen with 480 x 480 resolution ]
MAXIMUM SUPPORTED CAMERA STREAM RESOLUTION 1080P
Echo Show 2nd Generation [10.1” screen with 1280 x 800 resolution]
SUPPORTS 4K CAMERA STREAMS (H.264 only)
Echo Show 5 (just announced) [5.5” screen with 960 x 480 resolution]
WE WON’T KNOW UNTIL WE GET A UNIT IN HAND TO TEST, BUT I ASSUME IT WILL SUPPORT 4K STREAMS
Would seem that sending a 4k stream is worthless in terms of eating bandwidth, etc. Even 1080 may be overkill on screens this small.
Since the actual screen resolutions are all smaller than 1080P, the camera view will be scaled down so its not like you are going to get a real HD experience/quality anyway. I run most of my cameras at 720P or 1080P. (Certainly 720P for wireless connected cameras.)
My 2nd stream is set to 640x480 (*which for some odd reason is the max resolution for Sub Stream) H264 and this does work with Echo/Monocle.
It’s not unusual for a camera to limit the resolution on secondary streams. I think the manufacturers are putting in these limits in effort to prevent taxing the hardware too much.
My optional 3rd stream is set to 1280 x 720p but when viewing the media information through VLC the resolution is showing as 704 x 578 (3:4) and I cannot get this stream to display on Echo/Monocle.
Lucky you, many cameras only support 2 streams! Not sure what’s going on with the third stream in this case. Is it using H.264, does it include an audio channel and if so what audio codec is it using? Try rebooting the camera to see if the “correct” streaming resolution kicks in? Does the resolution in VLC change if you set it to some other resolution setting?
