I have some query regarding decoder and VPE. I have listdown it as below:

1). What will be the output image-format of ducati decoder?

2). If i want to convert decoded format to BGR24 usng VPE. How can i do that?

I guess you are asking for gst ducatih264dec, the format is NV12

Please check VPE user guide:
software-dl.ti.com/.../Foundational_Components_Kernel_Drivers.html

Vpe itself is capable of converting to RGB but gstvpe element does not but you could add this support to gstreamervpe element.

Hello Kishan,

Please could you let me know for which one you are asking - VPE m2m IP in the linux kernel or for gstreamer VPE element?

Hello Margarita,
I simply want to do like convert NV12 data to RGB24. Can i?
What should be required steps to do that?

Hello,

Please check the VPE guide, there is chapter "Testing the driver" with example.

But if you want to use Gstreamer VPE element you must add RGB support on the output.
The Gstreamer VPE element supports on the output NV12, YUY2 and YUYV.

Hello Margarita,
Thanks for guiding me.
So, how can i add RGB support on the output?

Hello Margarita,
Are you talking about like use gstreamer api by including some caps and elements as below:
"rtspsrc location=rtsp://admin:jenex#2018@192.168.1.108:554 latency=150 sync=false ! rtph264depay ! h264parse ! avdec_h264 ! videoconvert ! video/x-raw,format=(string)BGR ! appsink name=sink sync=false"

Am i right? or are you talking about something else?

Regards,
Kishan Patel.

Hello,

Could you provide more details how you want to use VPE? Do you want to use it in gstreamer or you want just to test VPE kernel driver(testvpem2m demo) or to test it with another demo?
So I could you provide you the right information.

Hello Margarita,
Actually, i want to make simple application like capture data from the on board-camera(mt9t111 output: "yuv" as till i know) and convert that frame to the "RGB" format.
So, first i have to test it using demo/command.
Then we can implement application.

Regards,
Kishan Patel.

Hello,

Okay.

1. So first you could try testvpem2m there is an example of just scaling/colorspace-converting a progressive 640x480 nv12 clip to a smaller resolution rgb clip:

$ ./testvpem2m 640_480p.nv12 640 480 nv12 360_240p.rgb24 360 240 rgb24 0 3

You could find more information regarding this example here:
software-dl.ti.com/.../Foundational_Components_Kernel_Drivers.html

2. Here is e2e thread that you could check :
e2e.ti.com/.../660340
This thread is for capturevpedisplay demo and how to add rgb24 support to this demo.

3. Gstreamer case this support could be add since the default gstreamer VPE element does not support this.

Hope this informations helps you.

Hello Margarita,
I have checked above link and following steps as below:
1)cd ti-processor-sdk-linux-am57xxevm-05.00.00.15/board-support/linux-4.14.40+gitAUTONIC+4796173fc5-g4796173fc5
2)sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
3) sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_am57xx-evm_defconfig
4)sudo make ARCH=arm menuconfig (And enable VPE as per provided steps in a guide)
5)sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- zImage
6)sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules
7)sudo make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- headers-install

But after 5th step i got error as below:

Hello,

The VPE is enable by default.
You do not need to execute these steps. Just use the default PSDK.
You could directly try the vpe test demo.

Hello Margarita,
Okay.
So, how can i test vpe demo.
I have also clone code from "git://git.ti.com/vpe_tests/vpe_tests.git".
Then execute "make install".

But i got error as below:

root@am57xx-evm:~/vpe_tests# make install
gcc -g -Wall -I/uapi -I -c -o vpetest.o vpetest.c

Hello,

NO. Please check under /usr/bin or MACHINE=am57xx-evm bitbake vpe-tests and cp testvpem2m demo.
After that execute ./testvpem2m 640_480p.nv12 640 480 nv12 360_240p.rgb24 360 240 rgb24 0 3.

Hello,

I am sorry Kishan you were using PSDK5.0 right?

If yes, please you could use test-v4l2-m2m.

Here is the command :

Hello Margarita,
Thanks for reply.
Now, how can i use it in a program means like i am capturing raw data in NV12 format and then want to convert it in BGR using VPE. Can i? How can i use it?.

Regards,
Kishan Patel.

Hello,

You asked how you could test nv12->rgb via VPE. test-v4l2-m2m is just a demo to test VPE. You could try to check the new .rgb file on PC if you want.

You could also try capturevpedisplay demo. This demo is under /usr/bin

But first please check this thread, Manisha's answer.

https://e2e.ti.com/support/arm/sitara_arm/f/791/t/660340

and apply changes.

Here is how you could build this demo:

MACHINE=am57xx-evm bitbake omapdrmtest

You could try to use gsreamer vpe plugin but at this moment this plugin does not support rgb on the output. But since the VPE low level driver support it, it is possible to add this support for gstreamer vpe plugin.

Here is the command how you could build gstreamer vpe plugin :

MACHINE=am57xx-evm bitbake gstreamer1.0-plugins-vpe

If you make change in the code you must rebuild and cp to the board. Here is the command for this:

MACHINE=am57xx-evm bitbake <recipe> --force -c compile

Hope this helps.

Hello Margarita,
Thanks.
So, can i use "ducatih264decvpe" in gstreamer api?
Meanse if i use below command, its working properly:

gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.5:554 ! rtph264depay ! h264parse ! ducatih264dec ! videoconvert ! waylandsnk sync=false

Now, how can use VPE in this command?

I have tried as below:
gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.5:554 ! rtph264depay ! h264parse ! ducatih264decvpe ! waylandsnk sync=false

But, i could not.

Hello,

As I said gstreamer vpe element does not support rgb on his output. But You could add this support.

Hello Margarita,
I have also 2 other apis as below:
1).gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.5:554 ! rtph264depay ! h264parse ! ducatih264decvpe ! 'video/x-raw, format=(string)NV12, width=(int)800, height=(int)600' ! waylandsink
2).gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.5:554 ! rtph264depay ! h264parse ! ducatih264decvpe ! 'video/x-raw, format=(string)BGR, width=(int)800, height=(int)600' ! waylandsink

So, here 1st one is working properly and 2nd one is not working.
So, thats why are you saying that BGR is not supported?
If yes, Then what should i follow the steps?

Hello,

kishan patel14 said:
So, thats why are you saying that BGR is not supported?

you must add this support in the gstvpe code!

Look into the gstvpe.c file, there you will see that :

static GstStaticPadTemplate src_factory = GST_STATIC_PAD_TEMPLATE ("src",
    GST_PAD_SRC,
    GST_PAD_ALWAYS,
    GST_STATIC_CAPS (GST_VIDEO_CAPS_MAKE ("NV12")
        ";" GST_VIDEO_CAPS_MAKE ("YUYV")
        ";" GST_VIDEO_CAPS_MAKE ("YUY2")));

There is no RGB.

But you could make changes in gstvpe.c file to support this.

On first look you must add in this function static GstStaticPadTemplate src_factory RGB.

In this one gst_vpe_fourcc_to_pixelformat also.

Check these function gst_vpe_set_output_caps.

In gstvpebuffer.c check gst_vpe_buffer_new and gst_vpe_buffer_priv functions.

I would recommend you to check how the other formats are added and to dig deeper in gstreamer vpe element.

Hope this helps.

Hello Margarita,
Thanks for reply.
Actually, i could not find "gstvpe.c" file.

Hello Margarita,
I have also one doubt about VPE.
In gstreamer plugin vpe could not provide output in BGR foremat. So, how can demo-application has convert YUV to RGB format?.
Means what has been used by that demo-app?

Kishan Patel.

Hello,

MACHINE=am57xx-evm bitbake gstreamer1.0-plugins-vpe

/tisdk/build/arago-tmp-external-linaro-toolchain/work/am57xx_evm-linux-gnueabi/gstreamer1.0-plugins-vpe/git-rx.xx/git/src
The both files are there.

Hello Margarita,
Okay, I am doing bitbake.
In parallel time can you provide me actual steps to follow after bitbake,please.
I have understand that i have to add RGB in one file. But i could not get all steps properly.

Kishan Patel.

Hello,

Please check previous answer again they are two files, gstvpe.c and gstvpebuffer.c not one.
I have pointed you some of the functions that you could change in order to add this support.
Note: I will be OoO next week so here is what you could add to debug gstvpe --gst-debug=vpe:3 you could raise the level of debug of course.

Hello Margarita,
I have completed bitbake process and could not find sorce file.
I have got 3 ipks as below:

Hello Margarita,
Actually, I had installed ipks after bitbake and i can find that source file also on board.

TI__Guru* 80190 points

Hello,

The source code is on your PC.
You should not install gstreamer-vpe plugin since it is already included in PSDK.
Please, find the source code in /tisdk/build/arago-tmp-external-linaro-toolchain/work/am57xx_evm-linux-gnueabi/gstreamer1.0-plugins-vpe/git-rx.xx/git/src
When you make your changes you must rebuild the plugin by using this command:
MACHINE=am57xx-evm bitbake gstreamer1.0-plugins-vpe --force -c compile
The new gstvpe lib you could find here:
/tisdk/build/arago-tmp-external-linaro-toolchain/work/am57xx_evm-linux-gnueabi/gstreamer1.0-plugins-vpe/git-r2.19/git/src/.libs
The name is libgstvpe.so.
If you could not find .libs folder please press ctrl+h to see it.
After that you must copy the new libgstvpe.so lib on the board under this path /usr/lib/gstreamer-1.0
You could test this with simple pipeline - gst-launch-1.0 videotestsrc ! <capsfilter> ! vpe ! <capsfilter> ! fakesink silent=false -e -v

Hello Margarita,
Thank you. I can find source file. I have modified "gstvpe.c" file as below:

static GstStaticPadTemplate src_factory = GST_STATIC_PAD_TEMPLATE ("src",
GST_PAD_SRC,
GST_PAD_ALWAYS,
GST_STATIC_CAPS (GST_VIDEO_CAPS_MAKE ("NV12")
";" GST_VIDEO_CAPS_MAKE ("YUYV")
";" GST_VIDEO_CAPS_MAKE ("RGB")
";" GST_VIDEO_CAPS_MAKE ("YUY2")));

static int
gst_vpe_fourcc_to_pixelformat (guint32 fourcc)
{
switch (fourcc) {
case GST_MAKE_FOURCC ('Y', 'U', 'Y', '2'):
case GST_MAKE_FOURCC ('Y', 'U', 'Y', 'V'):
return V4L2_PIX_FMT_YUYV;
case GST_MAKE_FOURCC ('N', 'V', '1', '2'):
return V4L2_PIX_FMT_NV12;
case GST_MAKE_FOURCC ('B', 'G', 'R', '3'):
return V4L2_PIX_FMT_BGR24;
}
return -1;
}

Is it right?

And i have also checked other function but i am feeling scare to modified other things.
What should i change like what should i keep size in "gstvpebuffers.c" file?

Regards,
Kishan Patel.

Hello Margarita,
I have also modified "gstvpebuffers.c" file as below:

GstBuffer *
gst_vpe_buffer_new (GstVpeBufferPool * pool, struct omap_device * dev,
guint32 fourcc, gint width, gint height, int index, guint32 v4l2_type)
{
GstVPEBufferPriv *vpemeta;
GstVideoCropMeta *crop;
int size = 0;
GstBuffer *buf;
GstAllocator *allocator = gst_drm_allocator_get ();

buf = gst_buffer_new ();
if (!buf)
return NULL;

switch (fourcc) {
case GST_MAKE_FOURCC ('A', 'R', '2', '4'):
size = width * height * 4;
break;
case GST_MAKE_FOURCC ('Y', 'U', 'Y', '2'):
case GST_MAKE_FOURCC ('Y', 'U', 'Y', 'V'):
case GST_MAKE_FOURCC ('B', 'G', 'R', '3'):
size = width * height * 2;
break;
case GST_MAKE_FOURCC ('N', 'V', '1', '2'):
size = (width * height * 3) / 2;
break;
}

and followed other steps to force-compile, replace library.

Then execute below command:
===========================
gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.5:554 ! rtph264depay ! h264parse ! ducatih264decvpe ! 'video/x-raw, format=(string)BGR, width=(int)800, height=(int)600' ! waylandsink

===========================
gst-launch-1.0 -v rtspsrc location=rtsp://888888:888888@192.168.1.5:554 ! rtph264depay ! h264parse ! ducatih264dec ! vpe ! 'video/x-raw, format=(string)BGR, width=(int)800, height=(int)600' ! waylandsink

But, still its not working.

Kishan Patel.

Hello Margarita,

I have modified "grammar.y" file at path "tisdk/build/arago-tmp-external-linaro-toolchain/work/armv7ahf-neon-linux-gnueabi/gstreamer1.0/1.12.2-r0/package/usr/src/debug/gstreamer1.0/1.12.2-r0/gstreamer-1.12.2/gst/parse/grammar.y" in function "static gint

gst_parse_perform_link (link_t *link, graph_t *graph)".

I am attaching that modified file.

Then execute "MACHINE=am57xx-evm bitbake -f -c compile gstreamer1.0".

Then copy 3 libraries (libgstreamer-1.0.so , libgstreamer-1.0.so.0 , libgstreamer-1.0.so.0.1202.0) on am5728_board at path "/usr/lib".

And execute commands as Below. Please,check its log:

Command:
--------------
gst-launch-1.0 --gst-debug=vpe:3 -v rtspsrc location=rtsp://888888:888888@192.168.1.4:554 ! rtph264depay ! h264parse ! ducatih264dec ! vpe ! 'video/x-raw, format=(string)BGR3, width=(int)800, height=(int)600' ! waylandsink

Log:
------
Please,check log file.

Command:
--------------
gst-launch-1.0 --gst-debug=vpe:3 -v rtspsrc location=rtsp://888888:888888@192.168.1.4:554 ! rtph264depay ! h264parse ! ducatih264dec ! vpe ! 'video/x-raw, format=(string)NV12, width=(int)800, height=(int)600' ! waylandsink

Log:
------
Please,check log file.

I have modified many things. Can you guide me that what should be wrong to link "VPE" and "waylandsink"?

Regards,

Kishan Patel.

Hello,

I do not understand why you are modifing the grammer_y file at all.
You should not do this.
Your problem is this :
WARNING: erroneous pipeline: 2_could not link vpe0 to waylandsink0, waylandsink0 can't handle caps video/x-raw, format=(string)BGR3, width=(int)800, height=(int)600

As you could see waylandsink can not handle the caps filter.
I already wrote you that with gst-inspect-1.0 waylandsink what are the formats that it accepts.
Look every gstreamer element has input and output.
The input is called sink the output is src. When you link two gstreamer elements the src of first one and sink of the second must match.
For example, YUY2 to vpe's input -> capsfilter (NV12) -> waylandsink. When you have in the capsfilter NV12 it "tells" to vpe to convert the format from YUY2 to NV12 in this exmaple. In this case waylandsink accepts on his input NV12 so all works.
Gst-inspect command displays what capabilities the elements has, properties etc..

However please check this thread:
e2e.ti.com/.../610113

Hello,

E2e thread update:
In PSDK 5.0, waylandsink supports NV12, YUY2 and BGRA on the input.
arago-project.org/.../

In previous PSDK version waylandsink supports NV12.

Hello Margarita,
Now, i have one doubt about to use RGB3/BGR3. To use RGB/BGR, i have add file "video-format.c" as below:

"case GST_MAKE_FOURCC ('R', 'G', 'B', '\0'):

return GST_VIDEO_FORMAT_RGB;

case GST_MAKE_FOURCC ('B', 'G', 'R', '\0'):

return GST_VIDEO_FORMAT_BGR;"

Here i can see format options as (GST_VIDEO_FORMAT_RGBx, GST_VIDEO_FORMAT_BGRx). So, would i have add lines as below to use RGB3(RGB24)/BGR3(BGR24):

"case GST_MAKE_FOURCC ('R', 'G', 'B', '3'):

return GST_VIDEO_FORMAT_RGBx;

case GST_MAKE_FOURCC ('B', 'G', 'R', '3'):

return GST_VIDEO_FORMAT_BGRx;"

Regards,
Kishan Patel.

Hello Margarita,

I am attaching one file which can provide details of current issue with including debug_print, file_path, Modified function's definition, all i have mention in this file.

Please, check this file and if you can know what should i add to solve this issue,Please tell me.

Hello Kishan,

Please use this pipeline with this caps:

gst-launch-1.0 -v videotestsrc ! video/x-raw, format=NV12, width=1280, height=720 ! vpe ! 'video/x-raw, format=(string)GBR, width=(int)640, height=(int)480' ! waylandsink

the log that you shared does not work for me.

Please verify that you have added gbr correctly to the waylandsink by using this pipeline:

gst-launch-1.0 -v videotestsrc ! video/x-raw, format=NV12, width=1280, height=720 ! videoconvert ! 'video/x-raw, format=(string)BGR, width=(int)640, height=(int)480' ! waylandsink

Please use the default armv7ahf-neon-linux-gnueabi/gstreamer1.0-plugins-base/1.12.2-r0/gst-plugins-base-1.12.2/gst-libs/gst/video/video-format.c file.

I have tested above pipelines. But it could not work and got output log as below:

I am sorry it is normal this gst-launch-1.0 -v videotestsrc ! video/x-raw, format=NV12, width=1280, height=720 ! videoconvert ! 'video/x-raw, format=(string)BGR, width=(int)640, height=(int)480' ! waylandsink

to fails with this error since the resolution is different on the videoconvert input and output. You must add videoscale or change the resolution to be the same like this:

gst-launch-1.0 -v videotestsrc ! video/x-raw, format=NV12, width=1280, height=720 ! videoconvert ! 'video/x-raw, format=(string)BGR, width=(int)1280, height=(int)720' ! fakesink

Please try to replace waylandsink with fakesink

gst-launch-1.0 -v videotestsrc ! video/x-raw, format=NV12, width=1280, height=720 ! videoconvert ! 'video/x-raw, format=(string)BGR, width=(int)1280, height=(int)720' ! fakesink

If this is working, please recheck the changes what you have made for waylandsink.

Please use default video-format.c not the file with your changes.

Hello Margarita,
I have checked above pipeline with fakesink, i dont get any error for this but waylandsink is not working for this pipelines.
Please, check below pipelines, its working fine.

1)gst-launch-1.0 videotestsrc ! video/x-raw, format=BGRx ! waylandsink
2)gst-launch-1.0 videotestsrc ! video/x-raw, format=BGRA ! waylandsink
3)gst-launch-1.0 videotestsrc ! video/x-raw, format=RGB16 ! waylandsink

Means, waylandsink working with these formats. But we can not use it with VPE. Right?(VPE support RGB24/BGR24)
And we have tested VPE with filesink, and its working properly.

I am revising these all things, because i have doubt is that is waylandsink support format which we have added(GST_VIDEO_FORMAT_RGB).

Regards,
Kishan Patel.
