PROCESSOR-SDK-AM62X: Apply gstreamer plugin

Hi Ryuuichi,

To include x264enc in your recipe, Could you please try the recommendation mentioned in the following link: https://stackoverflow.com/questions/62308375/how-to-get-compiled-gstreamer-plugins-installed-on-target-image-of-yocto.

Once installed, you could run this pipeline to verify (Camera-> H264Enc ->Filesink):

gst-launch-1.0 -v v4l2src device=/dev/video8 num-buffers=500 ! "image/jpeg, width=1920, height=1080, framerate=30/1" ! jpegdec ! videoconvert ! x264enc ! filesink location=output.264

Hello Suren-san,

Let me clarify about below.

To include x264enc in your recipe, Could you please try the recommendation mentioned in the following link: stackoverflow.com/.../how-to-get-compiled-gstreamer-plugins-installed-on-target-image-of-yocto.

I understand that above contents should be performed before performing bitbake command.
However, I'm not sure exact way.
Is it possible to list command/change which user should do before performing bitbake command ?

Here is example what I want.

--
Step 1
Add "LICENSE_FLAGS_WHITELIST += " commercial"" to conf/local.conf.


Step  2
Add "IMAGE_INSTALL_append = " gstreamer1.0-plugins-ugly"" to conf/local.conf.

Step 3
Maybe need to create "bbappend" file to patch current recipe, but I'm not sure how this should be done.

Step 4
Please write next step...

Hi Machida-san,

Can you add this 

PACKAGECONFIG_append_pn-gstreamer1.0-plugins-ugly = " x264" along with the steps 1 and 2 in local.conf

and compile using MACHINE=am62axx-evm bitbake gstreamer1.0-plugins-ugly

Let me know if this helps you detect x264enc upon issuing the command: gst-inspect-1.0 | grep 264

Hello Suren-san,

Let me confirm about below.

1.
Is my understanding we need to add both following two in local.conf correct ?

 "IMAGE_INSTALL_append = " gstreamer1.0-plugins-ugly""

"PACKAGECONFIG_append_pn-gstreamer1.0-plugins-ugly = " x264""

2.
You mentioned as shown below but I believe that I should use "am62xx-evm"(without "a".) because my target device is am62 not am62a.
Does it mistake about below ? (Or need to use "am62axx-evm" even though I use SK-am62 ?)

MACHINE=am62axx-evm bitbake gstreamer1.0-plugins-ugly

 Best Regards,

Yes, your understanding is correct on step 1.

Sorry for the typo, MACHINE should be am62xx-evm.

Best Regards,

Hello Suren-san,

My customer tried bitbake following above step. However, they got following error.

--
ERROR: Nothing PROVIDES 'gstreamer1.0-plugins-ugly'
gstreamer1.0-plugins-ugly was skipped: because it has a restricted license 'commercial'. Which is not whitelisted in LICENSE_FLAGS_WHITELIST
--

It seems that only following additional code for license is not enough.

"Add "LICENSE_FLAGS_WHITELIST += " commercial"" to conf/local.conf."

Is there any other idea to avoid above error ?

Hi Machida-san,

In order to enable x264, you need to go enable this recipe in Yocto: http://cgit.openembedded.org/openembedded-core/tree/meta/recipes-multimedia/x264/x264_git.bb?h=dunfell.

Also you need to remove the line with "LICENSE_FLAGS = "commercial"" and give it a try.

Did you mean that user just download this bb file to ../sources/oe-core/meta/recipes-multimedia/gstreamer ?
(I think that user do not need to add code on layer.conf or other conf file. Is my understanding correct ?)

Hi Machida-san,

Did removing the "LICENSE_FLAGS_WHITELIST += " commercial" help in resolving the issue?

"Did you mean that user just download this bb file to ../sources/oe-core/meta/recipes-multimedia/gstreamer ?
(I think that user do not need to add code on layer.conf or other conf file. Is my understanding correct ?)"

- If you include this bb file and add IMAGE_INSTALL_append = "x264" in local.conf file, that should solve the problem too. 

Let me know if this helps or provide us the steps again on what you did if it fails.

Suren
