Export with higher resolution

[EdJoPaTo]

I tried to export a recording with higher resolution as some fonts can be quite small in screen sharings. Simply adapting the width/height variables and xvfb args (as seen below) change the resolution internally (elements are larger/smaller) but the final video resolution seems to stay the same.

bbb-recorder/export.js

Lines 12 to 15 in 7f3ef44

	xvfb_args: ["-screen", "0", "1280x800x24", "-ac", "-nolisten", "tcp", "-dpi", "96", "+extension", "RANDR"]
	});
	var width = 1280;
	var height = 720;

I haven't found out where or how I might be able to change that. I assume that might be easy when knowing where to look and I just looked at the wrong places.

For someone else looking into it: I changed the linked source code towards the following as its nicer to edit but it does technically the same.

+var width = 1280;
+var height = 720;
 var xvfb = new Xvfb({
     silent: true,
-    xvfb_args: ["-screen", "0", "1280x800x24", "-ac", "-nolisten", "tcp", "-dpi", "96", "+extension", "RANDR"]
+    xvfb_args: ["-screen", "0", `${width}x${height + 80}x24`, "-ac", "-nolisten", "tcp", "-dpi", "96", "+extension", "RANDR"]
 });
-var width = 1280;
-var height = 720;

Hi @EdJoPaTo - you also need to increase the resolution of the browser in background.js. Here are settings we used to make small text legible:

                                chromeMediaSourceId: streamId,
-                                minWidth: 1280,
-                                maxWidth: 1280,
-                                minHeight: 720,
-                                maxHeight: 720,
-                                minFrameRate: 60,
+                                minWidth: 1920,
+                                maxWidth: 1920,
+                                minHeight: 1080,
+                                maxHeight: 1080,
+                                minFrameRate: 30,
                            }
