[jitsi-dev] Video appears black in receiving side under Windows 7


#1

Hey there,

Please try with a server. This will likely work better.

Cheers,
Emil

When making a video call in Jisti the receiving party sees black screen

After I did some google search, some people reported issues linked to
video codec in Windows 7 with other video software (other than a chat
client), they recommanded to install 'windows 7 codecs/ffdshow' and a
set of other tools. Nevertheless, this does not resolve the issue.

To go a bit further, I installed 'Linphone' in the same setup, and the
video worked in the Windows 7 side. I would guess that this eliminates
the codec (H.264) issue (maybe not ?)

Here's my environment:
--------------------

(Jitsi version) 2.2.4603.9615
(Sender) Windows XP 32 bits
(Receiver) Windows 7 32 Bits
(Protocol) using SIP registrar-less

The transmiting party has a camera, the receiving party doesn't.
I have tried H.264 and VP8 and both give the same symptoms.
using H.263-1998 crashes the JVM (but i have alraedy found a bug
declared for this)

With kind regards,

Hello,

I am not sure I understood your suggestion, by 'server' do you imply a
windows server or a SIP server?

In either case, I am required to get this to work properly in Windows 7 and
a registrarless setup (Some infrastructure constraints)

Your help will be grateful.

Regards,

Hey Tarik,

Hello,

I am not sure I understood your suggestion, by 'server' do you imply a
windows server or a SIP server?

You mentioned that you are using registrarless accounts. These are not particularly well supported in Jitsi and they are unstable and unreliable by nature (independently of Jitsi).

I therefore suggested that you try with an account on ippi.com and see if this works better for you.

Hope this helps,
Emil
