Hi Richard - I tried to do a test last night, and when I changed the setting to H.264, FMLE prompted me to change the file extension to f4v instead of flv, which I also did in the JWPlayer page that displays the video. using live, not VOD. Got a blank screen, even though video was being streamed. As soon as I changed all the settings back to VP6/flv, the live video worked. What am I doing wrong? ---

Thanks for the suggestions. Usually I stream LIVE using VP6, and in the webpage (JWPlayer) i have the file extension set to flv like this: So I tried H.264 using .f4v in the code above, and got a black screen. When I changed it back to VP6 and .flv, it worked well, just like it usually does. In order to stream live using H.264, what changes do I need to make to the player code? ---

Do I have to re-compile the swf object with flex, if I change the quality settings? ---

> You don’t have to de-compile anything because there is source code in the example. The VideoRecording has a clientFlex folder with Flex (sdk 3.2) version including source. > > Richard Sorry, I meant: after editing RecordingController.as, do I have to build the swf using Flex in order to use the new quality settings? I guess so, but I’m new to this world, so I’m asking just to be sure. Thanks [Previous page](https://community.wowza.com/t/how-to-improve-webcam-live-video-streaming-quality/645.md?page=1)
