i.MX6Q: mfw_isink error

[Tarek]

Hi,

I would like to use the ipu capabilities to scale and display multiple video steams to the same output TV.

I can only play one steam using the mfw_isink

#gst-launch videotestsrc ! mfw_isink axis-top=0 axis-left=0 disp-width=512 disp-height=348

When I start the second video it plays for few seconds and I get SIGSEGV

#gst-launch filesrc location=///home/root/mmfiles/clipcanvas_14348_offline.mp4 ! decodebin2 ! mfw_isink axis-left=513 disp-width=512 disp-height=348

This GDB trace:

VS1 created. in fmt[NV12] win(0,0-1024,576:1024x576) out win(0,0-512,348:512x348)

Have you tested it on latest yocto source code? I think it´s fixed, please, let me know if it isn´t

[Tarek]

It wasn't working for me on Yocto. Build from early January I think.

Is there any recent fix? When was that?

[daiane_angolini]

Well, I think the missing .so file was fixed.

But, I´m working to integrate 1.1.0 packages, in one day or two. So it would be better to test on it.

Could you, please, create a bug?

[Tarek]

I've created a bug

https://bugzilla.yoctoproject.org/show_bug.cgi?id=3781

Please let me know when you finish integrating the 1.1.0 packages.

Thanks,

Tarek

[daiane_angolini]

Sure. It will be posted on meta-freescale

[ChucoChe]

DaianeAngolini have you seen this problem?

[daiane_angolini]

Yes, it was a installation mistake.

It is fixed now. If someone could reproduce in latest source code, please, let me know.

[Tarek]

Hi Daiane,

Is it fixed for LTIB or Yocto ? Or  both?

Thanks

[daiane_angolini]

Have you reproduced this error on LTIB?

[Tarek]

No, isink is working fine for me on LTIB.
