I am trying to use jitsi on a netbook with an Atom processor to make SIP h264 video calls.
Receiving video works fine but when I start sending video the audio and video become unusable. The audio is very jittery and the video frame rate is extremely slow.
How does jitsi determine what resolution, frame rate and bit rate to use for a video call? Are these fixed parameters? Is there any way to force a lower resolution in some file?
Yes for the moment, these parameters are hardcoded.
You can change the resolution in the DataSource of our capture device.
- src/net/java/sip/communicator/impl/neomedia/jmfext/media/protocol/directshow/DataSource.java for Windows;
- src/net/java/sip/communicator/impl/neomedia/jmfext/media/protocol/videolinux2/DataSource.java for Linux;
- src/net/java/sip/communicator/impl/neomedia/jmfext/media/protocol/quicktime/DataSource.java for Mac OS X.
Frame rate and bitrate can be configured in src/net/java/sip/communicator/impl/neomedia/codec/video/h264/JNIEncoder.java for H264.
It would be great if there were settings for this in the gui.
Yes it is on our list, but unfortunately we have more higher priority tasks for now.
