Linphone 3.7.0 on imx6q: Black screen on the self view.

[konstantinkoval]

So, I am trying to use this linphone 3.7.0 on my Sabre platform for smart devices with OV5640 mipi camera.

I have done these steps:

1. Compile Linux BSP 4.0.1 3.0.35 from freescale

2. Compile linphone, ortp, mediastreamer2 for imx6q

3. Launch linphone, using "linphonec -V -d 3"

The problem is that I can see nothing on a self view (only a black screen). It seems like issue in Xv library which I have taken from freescale Ubuntu image (Linux BSP has not this library)

This phrase I see in linphone debug:

"ortp-error-Could not find suitable format or Xv port to work with."

I have attached the linphone log.

So, from this point I need some help to understand a causes of this problem. And I will appreciate for any advices!

Thanks...

Hi,

I am facing the same issue with linphone 3.10.2 version on imx6.  Were you able to find a solution for this problem ? It'd be of great help as I am stuck on this issue for a long time.

Thanks

Hi Konstantin, seems some libraries are missed,

suggest to use latest Freescale yocto

L3.10.17_1.0.0_IMX6QDLS_BUNDLE

So, now I have built the linphone with latest freescale yocto project (i.MX6Q: i.MX 6Quad Processors – Quad Core) and I have the same issue like in my first post. I mean this "ortp-error-Could not find suitable format or Xv port to work with."

Unfortunately, I was forced to downgrade the linphone from 3.7.0 to 3.6.1 version because of some obstacles during the compilation process which I couldn't overcome... (I can't build "antlr3-3.4" for belle-sip, for instance). It seems like problem between vivante video driver and Xv in Xserver. However, I don't know how to handle it and I need help! Perhaps, there are people here who worked with Xv and vivante, so please tell me, what should I do on a next step?

Here my xorg.conf:

*************************************************************

I don't know how to check what type of xserver (udev, dri, dri2, glx) is built by default...

Of course, I can provide any other necessary information. I will be really appreciate for any advices!

Thanks in advance!

Hi Konstantin,

please post this to meta-fsl-arm mailing list, so that someone familiar with xserver

could try to assist you.

I guess that my problem is closely related to vivante xorg driver for freescale SabreSD. However, I will follow your advice! Thanks!

P.S. By the way, how I can use the common mesa driver for Xorg instead of vivante? On this stage I do not need a gpu acceleration so it can be a workaround.

[igorpadykov]

P.S. please follow previous suggestion. :smileyhappy:

[konstantinkoval]

So, today I have completely rebuilt my image with the master branch (fsl-image-multimedia-full) and that damn error "ortp-error-Could not find suitable format or Xv port to work with." has gone! However, I still can't see the self view via linphone! Moreover, it crashes... And now it seems like problem in the mxc_v4l2 driver.

Here is the log message from linphone:

Hi Konstantin,

linphone 3.7.0 is very special software,

not sure that it can be supported here.

please post this to meta-fsl-arm mailing list, so that someone familiar with it

could try to assist you.

[konstantinkoval]

OK, I have done it! Now my post is placed on the meta-freescale mailing list. I will post a solution here or we can just close this thread.

OK, thanks. :smileyhappy:

Great news! Thanks a lot!

I will be testing this BSP on the next week. Probably, my issue will be solved...

Thanks again!
