Troubleshooting video quality issues
On the publisher side:
Problem: low frame rate
Solution(s):
- Increase the light in the room, natural light works best.
- Get a better web cam, good web cams capture a lot of frames with little light in the room.
- Lower the picture resolution requested by AVChat 3, some web cams just can’t capture 30fps at 400×300.
- Increase the movement in the shot, if there’s no movement Flash Player will not capture many frames/second because there’s no movement.
Problem: video stream does not use entire allocated bandwidth
Solution(s):
- Increase the light in the room, natural light works best. More light helps the web cam capture more details!
- Get a better web cam, good web cams capture a lot of detail with little light in the room. DV cams for example capture huge ammounts of data compared to normal web cams.
- Check your connection to the media server. When you’re publishing video you’re uploading data to the media server. Even tough you might have a 20Mbits/s Internet connection, that’s most probably your download rate, your actual upload rate could be much less. If you’ve configured the video chat to use as much as 768kbits/s per stream, this ammount of video data will not fit in real time trough your 350kbits/s upload pipe!
Problem: dark image or noisy image
Solution(s):
- Increase the light in the room, natural light works best.
- Get a better webcam.
Problem: no image at all or blank image
Solution(s):
- Make sure your web cam is not already used by another app
- Make sure the proper web cam is used by Flash Player (Right click -> Settings -> Web Cam tab -> Select the web cam you want to use from the drop down list)
