How to include x264enc on yocto

tejasshah · ‎10-30-2013

DaianeAngolini

I have a wandboard-dual board and I am using master branch.

Here is my build configuration:

Build Configuration:

BB_VERSION = "1.21.0"

BUILD_SYS = "x86_64-linux"

NATIVELSBSTRING = "Ubuntu-12.04"

TARGET_SYS = "arm-poky-linux-gnueabi"

MACHINE = "wandboard-dual"

DISTRO = "poky"

DISTRO_VERSION = "1.5+snapshot-20131030"

TUNE_FEATURES = "armv7a vfp neon callconvention-hard cortexa9"

TARGET_FPU = "vfp-neon"

I am doing a power consumption of video applications and therefore need to add x264enc to my image.

Now I have tried it two ways but x264 is not showing up in my final image.

1) First, I have placed gst-plugins-ugly-x264enc in local.conf file

COMMERCIAL_VIDEO_PLUGINS ?= " \

gst-plugins-ugly-x264enc \

"

and added this line to local.conf file: @PACKAGECONFIG_pn_gstreamer1.0-plugins-ugly += "x264" to enable it.

This configuration gives me an error:

| Computing transaction...error: Can't install gst-meta-video-0.10-r13@cortexa9hf_vfp_neon: no package provides gst-plugins-ugly-x264enc

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

2) Second, I have placed gst-plugins-ugly-meta in local.conf file

CORE_IMAGE_EXTRA_INSTALL += " \

gst-plugins-ugly-meta \

"

and again added this line to local.conf file: PACKAGECONFIG_pn_gstreamer1.0-plugins-ugly += "x264"

Please help. It is urgent

tejasshah · ‎11-07-2013

Hi Leo,

I compiled the image with the above changes in the local.conf file and the tar file has all the files you indicated above,

but still somehow there is no x264 plugin/element installed in the image.

Since you have the image compiled, is it possible for you to check if

it installed x264 plugin/element in your image?

LeonardoSandova · ‎11-07-2013

Oh, what we only did was installing the library. Now add the gstreamer element. Follow what Daiane suggested https://community.freescale.com/docs/DOC-95254#comment-7694

Leo

tejasshah · ‎11-09-2013

Hi Leo,

I added the bin and dev libraries as you had asked plus already had what Daiane suggested earlier.

LICENSE_FLAGS_WHITELIST = "commercial"

CORE_IMAGE_EXTRA_INSTALL += " \

x264-bin x264-dev \

"

PACKAGECONFIG_pn-gstreamer1.0-plugins-ugly += "x264"

After successful compilation of the image also, x264enc didn't show up in the image.

I also checked if I have got the libraries you had showed in your output, and they were also there.

$ tar tvf fsl-image-gui-wandboard-dual.tar.bz2 | grep x264

daiane_angolini · ‎11-11-2013

Please, be carefull on what gstreamer version you're using.

I was about to send an email to meta-oe mail list when I found this link:

http://comments.gmane.org/gmane.comp.handhelds.openembedded.core/41416

So, you can use local.conf OR bbappend.

You must build x264 BEFORE gstreamer (or, make sure you had sstate-cleaned gstreamer)

Use the right version.

Could you, please, try the suggestions from the link?

killedByBugs · ‎11-20-2023

Hi Daiane,

I wrote following 3 lines to my local.conf file.

CORE_IMAGE_EXTRA_INSTALL += " \

gst-plugins-ugly-meta \

"

and then I got the error:

Nothing provides gst-plugins-ugly-meta ...

Do you know how to solve this problem? Should I download "ugly-meta" from somewhere?

Thank you in advance

tejasshah · ‎11-13-2013

Hi Daiane,

Sorry for delay in reply.

I finally found a way to getting x264enc enabled in the image as suggested in that link.

I created a blank .bbappend file named gst-plugins-ugly_0.10.19.bbappend

and I just added PACKAGECONFIG +="x264" into that file. After compilation,

x264enc got added in the image.

Now, I tried running x264enc with the following command, but got a crash error. What is the reason for this?

My camera is working properly, so I don't think it is because of that.

root@wandboard-dual:~# gst-launch v4l2src num-buffers=500 ! video/x-raw-yuv ! queue ! ffmpegcolorspace ! queue ! x264enc ! matroskamux ! filesink location=outputh264.mp4 sync=false

LeonardoSandova · ‎11-13-2013

Enable logs (export GST_DEBUG=*:2) and remove this part of the pipeline 'video/x-raw-yuv ! queue ! ffmpegcolorspace ! queue '. These elements are not needed. Post the result.

Hi Leo,

I did the following:

Oh I see, sorry you indeed need the color space convertor. so add the FSL element, which is mfw_ipucsc ( v4l2src ! mfw_ipucsc ! x264enc)

LeonardoSandova · ‎11-13-2013

I see. It is a caps negotiation problem..... GStreamer check the pads and its caps to see if elements can be linked, if not then you get that message. For some reason, the v4l2src element is not providing the correct stream for neither the color-space nor the encoder.... Why are you using v4l2src? are you using a web cam? To check the caps being negotiated, just add '-v' to the pipeline.

Leo

tejasshah · ‎11-13-2013

Yes, I am using a web-cam. v4l2src works perfectly for all the encoders and containers.

Here it is with -v added to the pipeline.

LeonardoSandova · ‎11-13-2013

You need to figure out why caps are not fitting. Inspect the elements and use the -v flag. Also, try to use other video sources (videotestsrc is a good one but it is NOT enable by default :smileysad: )

tejasshah · ‎11-13-2013

Initially I wasn't getting caps at all because I didn't use ffmpegcolorspace.

Now I am getting caps but at the end it is giving the same errro.

LeonardoSandova · ‎12-17-2013

tejasshah

did you solve this problem (segmentation fault)?

tejasshah · ‎12-19-2013

Hi Leo,

Sorry for a late reply.

No, I haven't been able to solve the error.

I tried searching for that error on google and also on the community

and found some similar errors with camera crashing on community but none of the solutions

worked out.

Could it be something wrong with the source code?

LeonardoSandova · ‎12-20-2013

could you execute these instructions:

1. ulimit -c unlimited

2. restart your application and wait for "segment fault", there should be core file

3. gdb core*

4. gdb ./app core.12345

5. bt

I think the one provoking the fault is the encoder, but lets see.

Leo

tejasshah · ‎12-21-2013

So I ran the 1) instruction and restarted the application:

Oh I see. You need a image with developing tools.

On the image you baked (fsl-image-gui?) , can you add the following lines and bake again? That image will have the tool. BTW, once you got the tool, run it with

gdb --args gst-launch ..........

then wait for the fault, and type bt (backtrace).

Hi Leo,

Please ignore the last message, I didn't had the image with new features on the board earlier.

After getting the new image, I ran the command as you asked. After running the command, I ran

bt, but gives the error that there is no stack.
