RTSP Stream

[Fjmatt]

Has anyone had any luck streaming a generic RTSP stream to the ESPHome version of the NSPANEL?

I did some investigation on this some time ago and got limited by the Nextion display used on the NSPanel. Please take a look here: #1270 (reply in thread)

We are limited to the following commands to plot in the screen, so we should find a really good algorithm for converting the stream to those commands efficiently and reducing the number of calls, otherwise plotting an image takes just too long.

fill

Fill a defined area with specified color:

fill <x>,<y>,<w>,<h>,<color>
<x> is the x coordinate of upper left corner of defined fill area<y> is the y coordinate of upper left corner of defined fill area<w> is the width of the defined fill area<h> is the height of the defined fill area<color> is fill color, either decimal 565 Color Value or Color Constant
fill 20,20,150,50,1024// fills area 150x50 from (20,20) to (169,69) with 565 Color 1024.

line

Draw a line from point to point with specified color:

line <x1>,<y1>,<x2>,<y2>,<color>
<x1> is the x coordinate of the starting point of the line to be drawn<y1> is the y coordinate of the starting point of the line to be drawn<x2> is the x coordinate of the ending point of the line to be drawn<y2> is the y coordinate of the ending point of the line to be drawn<color> is line color, either decimal 565 Color Value or Color Constant
line 20,30,170,200,BLUE // draws line in BLUE from (20,30) to (170,200)

draw

Draw a hollow rectangle around specified area with specified color:

draw <x1>,<y1>,<x2>,<y2>,<color>
<x1> is the x coordinate of the upper left corner of rectangle area<y1> is the y coordinate of the upper left corner of rectangle area<x2> is the x coordinate of the lower right corner of rectangle area<y2> is the y coordinate of the lower right corner of rectangle area<color> is line color, either decimal 565 Color Value or Color Constant
draw 10,10,70,70,GREEN // draw a Green rectangle around (10,10) to (79,79)// effectively four lines from (x1,y1) to (x2,y1) to (x2,y2) to (x1,y2) to (x1,y1)

cir

Draw a hollow circle with specified radius and specified color:

cir <x>,<y>,<radius>,<color>
<x> is the x coordinate of the center point for the circle<y> is the y coordinate of the center point for the circle<radius> is the radius in pixels<color> is line color, either decimal 565 Color Value or Color Constant
cir 100,100,30,RED // renders a hollow Red circle with circle center at (100,100),// a 30 pixel radius, a 61 pixel diameter, within boundary (70,70) to (130,130).

cirs

Draw a filled circle with specified radius and specified color:

cirs <x>,<y>,<radius>,<color>
<x> is the x coordinate of the center point for the circle<y> is the y coordinate of the center point for the circle<radius> is the radius in pixels<color> is fill color, either decimal 565 Color Value or Color Constant
cirs 100,100,30,RED // renders a filled Red circle with center at (100,100),// a 30 pixel radius, a 61 pixel diameter, within boundary (70,70) to (130,130).
