Hello thanks for looking at this thread.. first of all dont mind the screenname. ._. all my usual screenames were taken so I got frustrated and banged my keyboard and accidently hit enter. -_- no idea how to change that
anyway here is my problem...
I want to broadcast pc games on a website called, Justin.tv short called JTV.
I got everything set up as I want it. and everything works perfect except for the FPS and bitrate.
The problem is that the FPS is not consistent. Its only consistent at 8.00 FPS higher then that, and it keep jumping between 5 and the desired FPS.
Now the same is with my bit rate. I imagine thats normal as it depends what it is on your screen.
I tried a bunch of differnt settings and found that the FPS is only stable at 8 and below, which is not good for broadcasting video games as you can imagine. ive tried putting more CPU on the FMLE didnt work... and all a bunch of other things I cant remember. ._.
I am using VHScrCap as my capture device and using stereo mix as my audio capture. format is H.264..
I hope someone can help me with this problem.
Thanks for your help in advance. and thanks for looking.
The problem is that your device is giving low FPS and thats why H264 is using lower bitrate to encode.
For eg: if you have specified 25 FPS at 1000 Kbps bitrate in FMLE. But if your device gives 10 FPS then H264 encoder will encode at 1000*10/25= 400 Kbps only.
So thats why your bitrate is also fluctuating because of FPS.
VHScrCap software has few limitaions. Since it is capturing data from Screen so its capturing speed is slow and thats why it is giving 8 or lesser FPS only. Try reducing the Input size so that it could capture more data and let me know your observations.
Also please let me know the settings that you are using for encoding and what is the actual FPS that device gives after reducing the Video size
Input size at 240x180 (normally 320x240) still same problem.
Input size at 80x60 problem still persistets, I see no apparant improvement what so ever. so still switching between 5 and the desired FPS which is 20.
My setting are...
Device : VHScrCap
Format : H.264 > advanced encoder settings > Profile : Main
Keyframe frequency : 5 seconds.
Frame rate 20.00
Input size: 320 x 240
Bitrate : 500
Output size: 320x240
Device : Stereo Mix (Realtek High Definition)
Format : Mp3
Channels : stereo
Sample rate : 22050
Bit rate : 48
Hope this helps.
I'm having the same problems. I'm using windows 7 64-bit and the latest Flash Media Live Encoder 22.214.171.12463.
I've tried using various capturing devices such as the (probaby best free capture driver) japanese SCFH DSF and no matter what I do I end up having >90% drop of frames. I've tried just about everything. With and without audio.
I read on the Justin.TV forums that it's a bug with Flash Media Live Encoder probably with 64-bit Windows 7.
I'm gonna try some crazy jumping through hoops to get it working such as Windows XP mode.
I just hope Adobe will improve this otherwise great piece of software.
I think problem is not of FMLE on Windows 7 because FMLE does not have any OS specific requirements to work.
Is your software compatible with Windows 7 64 bits.
What is the Input and Output FPS that you are getting in FMLE Statistics panel. Can you send me the screen shot of that.
Also, Please make sure that CPU usage of your machine should not go above 75%
Are you seing any drops is statistics panel(Input or Output)?
Thank you for replying. I did some tweaking, looked at the stats and performance and surely enough - FMLE was taking up about 90% CPU at all times. So I went with a lower input and output resolution for it to crunch and got the CPU usage down to 60% or so. No output drops at all. Just now I've been encoding 8 hours straight. I sat the FPS to 30, and the average ouputted FPS is 29.98. The only drops are input drops which I can't believe are FMLE's fault.
