Linux/AM5728: VIP driver problem

vefone

Part Number: AM5728
Other Parts Discussed in Thread: TVP5158, , ADS7846

Tool/software: Linux

Hi,

TI, I test the tvp5158 on the am5728. And I found that I can not capture every channel independently.

I first start capture channel 1,then I start capture channel 2.After I start capture channel 2,the channel 1 is not ok.The vip can not get data from channel 1.

channel 1:

gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=-1 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! vpe num-input-buffers=8 ! queue ! waylandsink

channel 2:

gst-launch-1.0 v4l2src device=/dev/video2 num-buffers=-1 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! vpe num-input-buffers=8 ! queue ! waylandsink

I debug it by open debug option of vip driver,there are not irq from vip.

echo 8 > /sys/module/ti_vip/parameters/debug

if I use dmabuftest，it is ok if capture four channel.

dmabuftest --multi 4 -d /dev/video1 -c 720x288@YUYV -d /dev/video2 -c 720x288@YUYV -d /dev/video3 -c 720x288@YUYV -d /dev/video4 -c 720x288@YUYV -s 32:1920x1080

are there any problem of vip driver?

any suggestion?

Hello,

If you are use these pipelines:
gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=-1 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! vpe num-input-buffers=8 ! queue ! fakesink &
gst-launch-1.0 v4l2src device=/dev/video2 num-buffers=-1 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! vpe num-input-buffers=8 ! queue ! waylandsink
Do you observe the problem?

What is PSDK version that you are using?
Could you provide the debug logs from vip and gstreamer?

Please check these e2e threads they could be in help:

From the log,it seems that only the /dev/video2 is work fine.

if I run "gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=-1 io-mode=4 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! vpe num-input-buffers=8 ! queue ! fakesink", the vip log are:

It shows me that the second capture will make the first capture not work.The root case should be the vip driver.There are some reason that I don't know.

I am using the SDK03.01 and SDK04.01.

Hello,

Please run:
echo 3 > /sys/class/video4linux/videoX/dev_debug
You could check this guide for vip debugging:
processors.wiki.ti.com/.../Linux_Core_VIP_User's_Guide
Could you add the gst debug log.
I will consult with the vip expert also.

Hi Vefone,

The logs that you shared doesn't suggest any issue with VIP. VIP is receiving the interrupts on both the channels.

Also, dmabuftest is successfully able to capture multiple channels, this as well suggest no issues with VIP driver.

I tried below pipeline, suggesting no issues with vpe and waylandsink plugin too -
gst-launch-1.0 videotestsrc ! 'video/x-raw,format=(string)YUY2,width=(int)640,height=(int)480' ! queue ! vpe ! waylandsink &
gst-launch-1.0 videotestsrc ! 'video/x-raw,format=(string)YUY2,width=(int)800,height=(int)480' ! queue ! vpe ! waylandsink &

These all points that v4l2src gstreamer plugin has issues running multiple instances. Can you enable the debug logs for v4l2src plugin as well for kernel log as Margarita suggested in her post above -
echo 3 > /sys/class/video4linux/videoX/dev_debug

Hello,

Please could you check with pipeline like this:

Hi,

manisha ,

I think the reason would be the vip and vpdma.

The first test：

I disable the pixel clock output of tvp5158,after I start four channel capture using the below command.

gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=-1 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! fakesink

gst-launch-1.0 v4l2src device=/dev/video2 num-buffers=-1 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! fakesink

gst-launch-1.0 v4l2src device=/dev/video3 num-buffers=-1 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! fakesink

gst-launch-1.0 v4l2src device=/dev/video4 num-buffers=-1 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! fakesink

then I enable the pixel clock output of tvp5158.By this way, I can capture four channel.Then I kill one gst-launch-1.0 process(one of four)，the other channels will not work fine.

I guess that:

1. It seems that I need to let the data input after I had streamed on all the channel.

2. If I stop one channle capture,the data is deranged(vpdma list is not ok),then the vip can not get the data(had not irq occurred).

The second test:

I use two tvp5158 module,one is connect to vin3a,one is connect to vin4a. the first tvp5158's four channel (/dev/video1、/dev/video2、/dev/video3、/dev/video4). The second tvp5158(/dev/video5、/dev/video6、/dev/video7、/dev/video8). I run the command to test：

gst-launch-1.0 v4l2src device=/dev/video1 num-buffers=-1 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! fakesink

gst-launch-1.0 v4l2src device=/dev/video5 num-buffers=-1 ! 'video/x-raw,format=(string)YUY2, width=(int)720, height=(int)240' ! fakesink

the two channel capture is fine.

After done the two test,I double that there are maybe some problem of vip driver.

1. There are some problem that the same vin support the multichannel. vip driver can not support multichannel independently.

if I start the first channel(vip had got the data and irq had occurred),then start the second channel,only the second channel work fine.

2. The different vin port(just like vin3a and vin4a),channel capture is independently.

I'm not familiar with vpdma. Especially the vpdma list.

any suggestion?

BR,

Hi Vefone,

To make the debugging simple, if the problem lies within vip driver, I would like to eliminate gstreamer complexity from the test scenario. Wondering if you can use Yavta to test multiple channel. Also, when you use below to generate debug logs, they are collected in dmesg, so please share the dmesg logs too.
echo 3 > /sys/class/video4linux/videoX/dev_debug

Also, enable the vip logs using
echo 3 > /sys/module/ti_vip/parameters/debug

You can run Yavta using below command. Here W and H are width and height you want to capture.
yavta -c60 -fYUYV -F/dev/null -sWxH /dev/videoX

Hi,

manisha .I had used the yavta to test it.The situation is the same as I described earlier(use the gst-launch-1.0).

I do two test as the before.

First:

enable the pixel clock out of tvp5158,run the command below；

echo '\n' | yavta -c100 -p -F/home/root/1.yuv --skip 2 -t 1/30 -f YUYV -s 720x240 /dev/video1

echo '\n' | yavta -c100 -p -F/home/root/2.yuv --skip 2 -t 1/30 -f YUYV -s 720x240 /dev/video2

here the log:

After I run "echo '\n' | yavta -c100 -p -F/home/root/2.yuv --skip 2 -t 1/30 -f YUYV -s 720x240~/dev/video2" to capture the second channel,the first channel capture will stop just like the picture above shows.

Second:

disable the pixel clock out of tvp5158,run the command below；

echo '\n' | yavta -c100 -p -F/home/root/1.yuv --skip 2 -t 1/30 -f YUYV -s 720x240 /dev/video1

echo '\n' | yavta -c100 -p -F/home/root/2.yuv --skip 2 -t 1/30 -f YUYV -s 720x240 /dev/video2

After that,I enable the pixel clock out of tvp5158.By this way, I can capture two channel completely.

here the log:

From where did you get the TVP5158 driver? Did you do any modifications to the original driver that you received?

0 vefone over 6 years ago in reply to Manisha Agrawal

Expert 2440 points

Hi,

manisha , I am using from the link:

I modify the driver tvp5158_enum_frame_size function only:

fse->max_height = fse->min_height = std_list[std].height; to fse->max_height = fse->min_height = std_list[std].height / 2;

If I do not modify that,the image is not ok,which had described below:

Hi,

Manisha, I had test the patch on the linux-4.9.41. It is work fine. I will merge it to SDK03.01 linux4.4.19.

Thank you very much!

Hi,

Manisha,we should do more on the vip_stop_streaming function. If not add that, stop one channel,the other channel will not work fine.

0 vefone over 6 years ago in reply to Manisha Agrawal

Expert 2440 points

Hi,
Manisha,
I use the patch,the start_stream operation is ok, the multichannel subdevice of one vport start operation independently,but if I stop one channel,the other channel is not ok.It is because of stop_dma function.

I modify the vip_stop_streaming like that:

Only stop_dma when the last channel stop. It is ok,but the second time I run the capture command.The kernel is not fine.

the command that I use is "gst-launch-1.0 -v -e v4l2src device=/dev/video1 num-buffers=150 io-mode=4 ! 'video/x-raw, format=(string)YUY2, width=(int)720, height=(int)240' ! vpe num-input-buffers=8 ! 'video/x-raw, format=(string)NV12, width=(int)720, height=(int)240' ! filesink location=/dev/null"

Here are the log:
