Hello

I would like to place my rmtp URL to the text box to show it by default. Now it is displaying “rtmp://localhost/livestreamrecord”. The .fla file given in the example is not letting me to do that. Is there a way to edit the .fla file and to make it customized according to my need.

I also would like to know is there a way to enhance the quality of the video ?

Regards

Dharam

You need the Flash Authoring tool to edit the .fla files.

… also,

Image quality can be changed with Camera settings in actionscript: setQuality, setMode and setKeyFrameInterval.

Quality and performance are trade-offs with these settings.
