v4l2 Capture pipelines on 8168 EVM using EZSDK (version 5_03_01_15)

Other Parts Discussed in Thread: TVP7002, TVP5147, TVP5150, THS7303, TVP5151

Hi,

Is it possible to capture and encode audio/video using v4l2 capture module and gstreamer on 8168 EVM. We were able to load the v4l2 firmwares as described in the following thread

http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/153145.aspx

However we could not run the capture pipelines as described on the wiki for 8168:

http://processors.wiki.ti.com/index.php/DM81xx_Gstreamer_Pipelines#Capture_Pipelines

Is there any document describing the steps required for capture and encode of Audio/video.

Thanks,

Amol

Gstreamer release (version 0.3) packaged in EZSDK version 5.03.01.15 doesn't support V4L2 src element. You will have to upgrade to gstreamer release version 0.4 from gstreamer.ti.com on your EZSDK to use V4L2 src. Find details to download and upgrade at http://processors.wiki.ti.com/index.php/DM81xx_Gstreamer_Plugin#Download

Hello Satish,

I tried with gstreamer tag "TAG_GST_DM81XX_00_04_00_00" but it didn't work as well. Can I run the pipeline as below to do a loopback of the captured video over HDMI:

gst-launch v4l2src always-copy=false queue-size=11 ! 'video/x-raw-yuv-strided,format=(fourcc)YUY2,width=1280,height=720,framerate=(fraction)60/1' ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink sync=false

Please provide sample pipeline for the same if possible.

Thanks,

Amol

Here is a loopback pipeline that you can try...

Hi Satish,

Did the above pipeline work at your end? I tried the same at my side but no luck. The omxbufferalloc element is not present in the tag version of the gstreamer we are using. Can you let us know the release with which you tested the above pipeline?

Thanks.

Hi Anmol,

As I suggested in the earlier post you need to use the gstreamer release 0.4 (i.e. - TAG_GST_DM81XX_00_04_00_00), that version of gstreamer has the omxbufferalloc element and other patches required for V4l2src to work.

Thanks,

Satish

Hi Satish,

I got the capture working with the 0.4 release. However I have few queries regarding the V4l2src module:

1) I am trying to capture a 640x480 resolution video and display it on HDMI. How would i use the scaler to provide a full screen display if my output resolution is 1080p60. (I tried to use the omx_scaler element but couldn't do it with v4l2src).

2) I tried encoding the captured video using the following pipeline

gst-launch-0.10 v4l2src always-copy=false queue-size=12 num-buffers=2000 ! 'video/x-raw-yuv-strided,format=(fourcc)NV12,width=1280,height=720,framerate=(fraction)60/1' ! omxbufferalloc numBuffers=12 ! omx_h264enc bitrate=5000000 ! gstperf ! filesink location=v4l2cap.h264

The gstreamer crashed. Logs for the same are attached herewith for your reference.

Is it also possible to capture audio using gstreamer. Can you provide some example pipelines for the same as well.

Thanks.

....Need some help as well here please

I would like to split the Captured video and display it on the HDMI , and stream it.

I have each scenario working separately

A. Capture and display locally on HDMI: (because I am capturing on the Component using a sony camera 1080i50 the fps is 25 buy this still works)

gst-launch -v v4l2src device="/dev/video0" always-copy=false queue-size=11 ! 'video/x-raw-yuv-strided,format=(fourcc)YUY2,width=1920,height=1080,framerate=(fraction)60/1' ! omxbufferalloc numBuffers=11 ! gstperf ! v4l2sink device="/dev/video1" show-preroll-frame=false sync=false min-queued-bufs=2

B. Stream the Capture over RTP/UDP

gst-launch v4l2src always-copy=false queue-size=12 ! 'video/x-raw-yuv-strided,format=(fourcc)YUY2,width=1920,height=1080,framerate=(fraction)60/1' ! omxbufferalloc numBuffers=12 ! omx_noisefilter ! omx_h264enc force-idr-period=300 i-period=100 bitrate=12000000 ! h264parse ! rtph264pay ! udpsink host=172.17.25.230 port=1234

I have used the testsrc to stream and display locally using this also with a time overlay (this works).

gst-launch -v videotestsrc !'video/x-raw-yuv, width=(int)640, height=(int)480' ! timeoverlay halign=left valign=bottom text="Stream time:" shaded-background=true ! tee name=t ! omx_scaler ! 'video/x-raw-yuv,width=1920,height=1080' ! v4l2sink show-preroll-frame=false sync=false min-queued-bufs=2 t. ! omx_h264enc ! h264parse ! rtph264pay ! udpsink host=172.17.25.70 port=1234

C. My script that does not work (I have moved the t. around and used Queue but to no success aswell )

gst-launch v4l2src device="/dev/video0" always-copy=false queue-size=12 ! 'video/x-raw-yuv-strided,format=(fourcc)YUY2,width=1920,height=1080,framerate=(fraction)60/1' ! tee name=t t.! omxbufferalloc numBuffers=12 ! gstperf ! v4l2sink device="/dev/video1" show-preroll-frame=false sync=false min-queued-bufs=2 t. ! omxbufferalloc numBuffers=12 ! omx_noisefilter ! omx_h264enc force-idr-period=300 i-period=100 bitrate=12000000 ! h264parse ! rtph264pay ! udpsink host=172.17.25.230 port=1234

(I think because the camera is 1080i50 the frame rate now comes out at 12.5fps not great but it works for now ) why did you insert decimate into the script

I also installed gst-openmax-GST_DM81XX_00_04_00_00 by downloading it and make gstomx_clean, gstomx and gstomx_install.

However, I still do not have omxbufferalloc elements.

Anyone could share the knowledge about how to fix it?

Thanks in advance,

Did you export the gstreamer environment variables to point to the new gst installation before executing the pipeline on the target.

For e.g. if the gstreamer is installed at /opt/ in your target then you can export the following environment variable.

export GST_REGISTRY=/tmp/gst_registry.bin
export LD_LIBRARY_PATH=/opt/gstreamer/lib
export GST_PLUGIN_PATH=/opt/gstreamer/lib/gstreamer-0.10
export PATH=/opt/gstreamer/bin:$PATH
export GST_PLUGIN_SCANNER=/opt/gstreamer/libexec/gstreamer-0.10/gst-plugin-scanner =

Hi Greg

Looks Fine except the way you have pasted your Forum post looks like you are missing data like the copy and paste did not wrap the text so i can't see the whole string.

Are you capturing from Component i.e.( RGB connectors) and displaying on the HDMI ? Are you using DM8168 EVM ?

If so ( Check the Video Capture Driver user guide 04.00.01.13) and ( Video Driver user guide 04.00.01.14)

Reset the board check the Video modules are loaded in the correct order and that you have copied the .KO modules from your build output to target FS where the same modules reside or are loaded from. syslink and cmemk drivers aswell. TP7002

Make sure you switch on your graphics planes and redirect V4L2 vpss driver /dev/video1 to the HDMI. using the echo commands I used above.

If you are capturing from a camera make sure that the height and width match, you can also insert a -v i.e. "gst-launch -v ....." and it will tell you that what the capture driver supports . I know If I try run this pipeline twice I get the same error as you. Something to do with the Vpss driver not closing when I destroy the pipeline.

Also test with videotestsrc , after you have it working replace with the v4l2 capture.also check that the format is correct. try this:

After all my typing which I will not delete If you look in the Trace above my format is incorrect and the driver tries all formats one after the other until it gets a match = 12.

Hope this helps

Cheers

Robin

Hi Robin,

The decimate=n option would drop every nth frame captured. Hence setting decimate to 2 would half the framerate.

Another thing you could try is to reduce the bitrate of the encoder to say 4 or 6Mbps, while keeping the full framerate.

There are stability issues with v4l2 capture, when the DDR is heavily loaded. We are looking at this right now. And shall let you know, once we have a fix.

Output a list of all the plugins to a file

"gst-inspect > file.txt"

Check out whats available. ie rtph264pay (which is a payloader) you can search for descriptions on freedesktop.org (search in google )

type "gst-inspect rtph264pay" this will give you a description of what you can set in the plugin and compatability between pad src and sinks.

h264parse is a parser for h264 which does chunking rtph264 (checks for frame boundries etc)will put it in realtime packets and udp then sends it out

So basicaly:

your server should look like this:

"use gst-launch -v ......." to get a trace out.

my board is booting fine for both sd card and tftp,nfs.

but unable to encode,decode and loopback video.

I have connected the hi focus pal camera at composite input as shown in below figure.

i followed the below steps.

This demo is the capture-encode demo included in the EZSDK. It takes an input video streaming from the component input (case 720p) of the daughter card(marked as J5J6J7) and encodes it in H264, the output is displayed through the HDMI output.

echo 0 > /sys/devices/platform/vpss/display0/enabled

Hi Asif,

For V4L2 capture display you need to use load-hd-v4l2-firmware.sh script which inserts all .kos required.

Please copy targetfs/usr/share/ti/ti-media-controller-utils/load-hd-v4l2-firmware.sh to targetfs/etc/init.d/load-hd-firmware.sh for V4L2 and

copy targetfs/usr/share/ti/ti-media-controller-utils/load-hd-firmware.sh to targetfs/etc/init.d//load-hd-firmware.sh for OMX firmware.

Capture_Encode demo uses OMX firmware for capture and display.

EZSDK05.05.02.00 is the latest available sdk with many bug-fixes. Please use this version.

Can you please share the logs from booting to capture_encode execution?

Hello,

mohammed asif said:
I am using dm8168 with daughter card, unable to capture video through composite input.

In EZSDK, currently media controller supports only TVP7002 the component capture through TVP7002.

For capture connected to the composite input you should add the external decoder and to use v4l2 capture driver.

Please follow these guides:

http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver

and

http://processors.wiki.ti.com/index.php/TI81XX_PSP_VIDEO_CAPTURE_Driver_User_Guide

As Ram Prasad wrote you should load the load-hd-v4l2-firmware.sh firmware when you are trying v4l2 capture. For OMX capture (capture_encode demo)the load-hd-firmware.sh should be used.

The capture_encode demo will not work if you are trying capture through composite input.

Based on the omx capture_encode demo log file it seems that the video source is not connected that is why the file is with 0 size.

hi,

i followed the below link.

http://processors.wiki.ti.com/index.php/DM81xx_AM38xx_Adding_External_Decoders_to_V4L2_Capture_Driver

Steps for Adding new Decoders

All the files related to new external decoders should be added in following kernel directory

$kernel_source/drivers/media/video/<external_decoder_directory_file>

MakeFiles and Kconfig files needs to be modified accordingly. Please refer to following kernel documentation on makefiles and Kconfig under following kernel directory.

$kernel_source/Documentation/kbuild/

TVP7002 decoder is added as the sub-device model in Linux Driver stack. Please refer following files for TVP7002 decoder implementation.

$kernel_source/drivers/media/video/tvp7002.c
$kernel_source/drivers/media/video/tvp7002_reg.h
$kernel_source/drivers/media/video/tvp7002_reg.h
$kernel_source/media/video/Makefile
$kernel_source/drivers/media/video/Kconfig

TVP7002 specifications could be found at tvp7002
Data about the external decoders like what inputs they support, how they are interfaced to VPSS VIP port, what is the I2C address etc, needs to be passed to V4L2 capture driver. This data is board dependent and needs to be filled based on decoder and how decoder is connected to VIP port.
ti81xxvin_config data structure needs to be field and passed it as platform data to the HDVPSS V4L2 capture driver. It includes many sub-structures and enums all those will be explained in sub-sequent sections in code

--------------------------------------------------

All the files related to new external decoders should be added in following kernel directorybelow is the $kernel_source/drivers/media/video/<external_decoder_directory_file>

but how and what should i... pleses find the below details for your reference.

hi margarita,

genereted and inserted both the modules tvp514x.ko and tvp7002.ko

kindly let me know the commands to encode/capture,decode and loopback the videos through composite input and hdmi output.

pleses find the below inserted modules on dm8168 for your reference .

Hello,

mohammed asif said:

You can not use OMX capture encode demo in use case capture source connected to the composite input. Check the previous posts. In capture_encode demo the capture component which is running on HDVPSS part of media controller captures the 1080p60/720p/1080i input from TVP7002 decoder on Catalog EIO board. The media controller's source code is under NDA and you can not modify it to add the tvp5147 support but you could obtain it by contacting your local FAE or TI representative.

In use case, composite capture on the EVM we have tvp5147 as external decoder that is why you should use v4l2. TVP5147 driver is already avaiable as a part of Linux kernel under $Kernel/driver/media/video/tvp514x.c. You just need to hook this up to V4L2 capture driver.

You could try to use v4l2 demos described here but you should make some modifications:

hi,

yes, according to your suggestion, i got the tvp514x.ko as a part of Linux kernel under $Kernel/driver/media/video.

even i insmod the same module. but where i can get the below Prerequisites

TI81XX PSP VIDEO CAPTURE Driver User Guide

V4L2 capture driver requires following modules to be loaded for its functioning.

syslink kernel driver module, referred as "syslink.ko"
loader user space program, referred as "slaveloader"
M3 BIOS Firmware binary, referred as "ti816x_hdvpss.xem3/ti814x_hdvpss_1G.xem3"
VPSS kernel driver module, referred as "vpss.ko"
TVP7002 decoder kernel module referred to as "tvp7002.ko"
V4L2 capture kernel module, referred as "ti81xxvin.ko"

Thanks and regards,

hi margarita,

Installation Guide

This is the TI81XX Linux VPSS(VPSS capture) Driver user installation guide. This documents the steps to get the VPSS Driver worked up on TI81XX based EVM(Simulator is not tested). This driver has the following dependencies outside of Kernel.

TI81XX PSP 04.04.00.02 release for TI814x, TI837x, TI816x, TI389x, TI385x and TI813x
Syslink 2.20.00.14 release (slaveloader)
_{HDVPSS 01.00.01.44 release ----> no file find at this location}

therefore i am using TI816x-HDVPSS-01.00.01.33.

Hi All,

To capture from the TVP5147 (composite) present in the DM816x you need to enable the driver for the TVP5147 and also integrate it with the main V4L2. Furthermore you would need to route the clock signal from the daughter card with a cable (solder it) since the signal is missing. Ridgerun already has the TVP5147 capturing properly and we modified omx_camera to be able to capture NTSC or component from TVP7002:
