EMGD errors on Atom E38xx (TIZEN IVI)

Hello!

I have prepared kernel 3.10.28 with recomendations from https://www-ssl.intel.com/content/dam/www/public/us/en/documents/guides/tizen-ivi-m2-kernel-ltsi-lin... https://www-ssl.intel.com/content/dam/www/public/us/en/documents/guides/tizen-ivi-m2-kernel-ltsi-lin... (january 2015 revision). Everything is completed successfully and graphical environment is loaded. But when i try to open USB camera from gstreamer i get errors from EMGD in dmesg output:

emgd_fbcon_setcmap ERROR: Invalid parameter

emgd_user_framebuffer_create ERROR: Userspace passed invalid bo handle[3]

emgd_get_param ERROR: invalid parameter passed to GETPARAM ioctl:22

I am using emgd from https://downloadcenter.intel.com/download/23820 Intel® Download Center .

Video files succesfully opened with gstreamer. How i may open USB camera? How to get rid off of these errors?

Best Regards,

Maksim Gusev

Hi MaksO_oN,

I believe EMGD is obsolete.

I happened to work on yocto environment and find this article for graphics driver:

http://www.intel.in/content/dam/www/public/us/en/documents/guides/atom-e3800-celeron-n2xx-yocto-bsp-... http://www.intel.in/content/dam/www/public/us/en/documents/guides/atom-e3800-celeron-n2xx-yocto-bsp-...

This link suggest using drm with lib-vaapi support and gstreamer-vaapi

Hello Maks,

Please refer to the section 3.7.4 How to Use Gstreamer, Video encoding for camera input from Document # 546069 Tizen* IVI 3.0 M2 Kernel 3.10 LTSI Linux* Support Package for the Intel® Atom™ Processor E3800 Series Getting Started Guide January 2015, and let us know if this is useful.

Best Regards.

Hello, Josue,

I tried this section but Gstreamer didn`t find vaapiencode_h264 pipeline element. Maybe i have a mistake in installing gstreamer. I can try to rebuild all userspace software in section 3.5 if it may help me with my problem.

I opened video and audio files with command: gst-launch-1.0 playbin uri=file://pathtofile and it works well, But when i opened video from ModelloPlayer video didn't attach to ModelloPlayer window and has it's own window (just like when executing the command gst-launch-1.0 playbin uri=file://pathtofile). When i click on other place except video surface, video goes to background. How may i attach video surface to Player window?

Best Regards.

Maks.

Hello Maks,

If the driver is properly installed, including the VAAPI extensions, then encode works.

Best Regards.

Hello, Josue.

I tried reinstalling gstreamer-vaapi-0.5.7. On configure step (./configure --prefix=/usr --enable-wayland –-enable-encoders) i was see, what enable-encoders element was not found but this was only warning and confugure sucess ended. After that i tried this step on gstreamer-vaapi-0.5.9 and configure step successfully complete without warnings.

After installing of gstreamer-vaapi-0.5.9 video stream from camera successfully opened with Gstreamer, though in dmesg output was string "emgd_get_param ERROR: invalid parameter passed to GETPARAM ioctl:22" .

Although emgd error string in dmesg is stay, but problem with camera is solved.

 

Best Regards.

Maks.

Hello, Eunike.

The problem with camera is solved and it works through gst-launch-1.0 pipeline(displayed on wayland surface). But then i tried to open the camera in my html app in tag, i don't see the image from camera, although the lamp on the camera is lit, which means it opened succesfully i think.

Also i installed Modello Player from SDK Samples and when i opened a video it was displayed on wayland surface and not in tag. I didn't see video frames after it started playing, and only "Super+Tab" helps to see the video.

Why didn't the video attach to tag and what can i do to solve this problem? May be this problem is in webkit browser, that displays html application, or Gstreamer didn't have some sink to attach video to browser window?

Best Regards.

Maks.

Hi, Maks! Glad to see that your camera issue is solved. Have you checked with a Linux consultant regarding these other issues? LynnZ.

Hello, LynnZ!

When i posted this question, i was think, that my problem is in EMGD errors. But yesterday i load default linux kernel without ISP an EMGD and problems with displaying are not going away. And now i think, that EMGD errors are not react on video displaying. But it is a strangely, that this errors are transmit to dmesg, when i open a video.

Best Regards.

Maks.
