Yawcam -> Settings -> Stream
The stream output is the mode where you can stream video. Yawcam uses MJPEG as compression.
Port - This is the port number the web server for stream will open on.
Scale to - This option let you scale the size of the output on the webpage. This doesn't affect the bandwidth usage it only scales the image.
Image quality - Use the slider to select the image quality. This option only affects the output when the Java Applet is selected. Remember that higher quality will require more bandwidth.
Additional settings... - Opens a dialog with more settings for the stream output. More info about this dialog here.
About the Templates...
If you don't want to use the page designer, you can change the HTML for the page by your self by editing the templates. You find the templates in your stream directory: e.g. C:\Users\%username%\.yawcam\stream
The files are named:
template_ja.html - Used when Java Applet is selected.
