[jitsi-users] Are there plans to improve the performance/resolution quality of desk-top streaming?


#1

To compete with Skype or Lync, the screen resolution and update speed is
really important.

Hi Daniel,

I'm not sure if there are plans to change the defaults/add more presets, but you can change this yourself from the .properties configuration file or through provisioning. We have tested the following settings, which appear to apply to both video chat and screen sharing.

net.java.sip.communicator.impl.neomedia.video.bitrate=5000
net.java.sip.communicator.impl.neomedia.video.height=720
net.java.sip.communicator.impl.neomedia.video.width=1280

Increasing the resolution may be possible, but I haven't tested it. I am however in the process of choosing an optimal bitrate, so I know this can be used.

We generally stream with source resolution unless the receiving screen is
smaller in which case we stream with the resolution of the smaller screen.

There was a bug with the negotiation though so if you are testing with 2.2
you might want to try the latest nightly.

Cheers,
Emil

Just noticed that we still have a long standing bug that I thought was gone
but apparently not. I think that must have contributed to your experience.

The first time you share your screen with Jitsi, it could sometimes happen
(and that sometimes can be "often" on some systems) that quality on the
receiving site is abysmal. We'll have a look at it again but until then all
you need to do in such cases is just ask the sharer to stop streaming and
then start again *without* ending the call.

Hope this helps,
Emil

Do you know if this bug effected typing on the other screen? In 2.2,
when I type on the other screen, some of the characters are
mistranslated. For example, backspace and enter do totally different
things than they should. Has that been fixed in a nightly?

I have consistently experienced this too with very recent builds. It
looks like it hasn't been fixed. Also pressing the delete key (not
backspace) seems to cause an entire row to be deleted.

The following keystrokes are malformed (there may be more)

Backspace Key does not delete a character and move backward: it instead
acts as if you pressed the 'h' key.
Enter Key does not new line, it instead acts as if you pressed the "j" key.
Delete Key curiously does not delete the character in front of the
cursor, instead deleting a whole word BEFORE the cursor. This behaviour
is similar to "Ctrl+Backspace".

I have a hunch that these issues are all due to some improper escaping
of metacharacters: I have no idea about the implementation of this
feature but I dimly recall that "^H" is the control code for backspace
and ^J is a "line feed". Not sure about "Delete" but it's no doubt linked.

Hope this helps the diagnosis,
