L4T 28.1 : Gstreamer 1.0 and BusError on nvjpegdec plugin

_Syd · November 1, 2017, 7:21am

On TX1 , gst-launch-1.0 works fine , but i have issu without Error in C++ apps :

ubuntu@tegra-ubuntu:~$ gst-launch-1.0 videotestsrc is-live=true ! video/x-raw, format=I420, width=1640, height=1232, framerate=30/1 ! videorate ! video/x-raw, framerate=1/10 ! queue ! nvjpegenc ! fakesink

Execution ended after 0:00:10.777120569
Setting pipeline to PAUSED ...

Setting pipeline to NULL ...

ubuntu@tegra-ubuntu:~$

But, in my “main” application ( write in C++), i use TX1 28.1 and call the Gstreamer 1.0 plugin nvjpegdec :

mVideoSourceConvert = gst_element_factory_make("<b>nvjpegdec</b>", EXTRANAME("nvjpegdec_"));

GstCaps *lnvcaps = gst_caps_new_simple ("video/x-raw",
                "format", G_TYPE_STRING,"I420",
                     NULL);
    
    g_object_set (G_OBJECT (mVideoSourceConvert), "caps", lnvcaps, NULL);
        gst_caps_unref (lnvcaps);

I have crash with :

if you are an idea … thx

DaneLLL · November 2, 2017, 2:43am

Hi Syd,
Can you share detail about your usecase? Looks like you use nvjpegenc in the launch line and nvjpegdec in the C++ code? Is your case jpeg encoding or decoding?

josejich · November 3, 2017, 7:31am

Hi Syd,

First, check the following example just to doble check that your application is following the basic guidelines of Gstreamer:

https://gstreamer.freedesktop.org/documentation/application-development/basics/helloworld.html

The first pipeline that you launched using gst-launch seemed to work properly. On your application from what I can see, it seems like the error you got is related to the interaction of the element you are linking to nvjpegdec, from which element you are receiving and who are you feeding in the pipeline for that particular element? check if nvjpegdec has memory restrictions by running

gst-inspect nvjpegdec

_Syd · November 7, 2017, 5:24pm

Thx for reply,

first, i try to decode :

This command line works well …

gst-launch-1.0 v4l2src device=/dev/video1 ! image/jpeg,with=1920,heigth=1080,pixelformat="MJPG" ! jpegdec ! clockoverlay ! tee ! queue ! video/x-raw,framerate=30/1 ! omxh264enc ! avimux ! filesink location="test.avi" sync=false

i use NVJpegDec for decode “image/jpeg” from a see3cam CU130 on MJPEG format (USB2 , FHD and 60/1 ).

Of course, i’m testing “helloworld” for know how i can do use that and with Inspect plugins , i have :

gst-inspect nvjpegdec


Pad Templates:
  SINK template: 'sink'
    Availability: Always

      image/jpeg

              framerate: [ 0/1, 2147483647/1 ]

in C++, that works with jpegdec plugins.

I try on TX2 , same issu

But , what did you mean about :

DaneLLL · November 10, 2017, 6:20am

Hi Syd, not sure what your issue is. Do you see failure in decoding JPEGs via nvjpegdec?

_Syd · November 13, 2017, 3:08pm

For resume :
JpegDec works on TX1/TX2

gst-launch-1.0 v4l2src device=/dev/video1 ! image/jpeg,with=1920,heigth=1080,pixelformat="MJPG" ! jpegdec ! clockoverlay ! tee ! queue ! video/x-raw,framerate=30/1 ! omxh264enc ! avimux ! filesink location="test.avi" sync=false

nvJpegDec works on TX2 , give only 4K video on TX1.

gst-launch-1.0 v4l2src device=/dev/video1 ! image/jpeg,with=1920,heigth=1080,pixelformat="MJPG" ! nvjpegdec ! clockoverlay ! tee ! queue ! video/x-raw,framerate=30/1 ! omxh264enc ! avimux ! filesink location="test.avi" sync=false

In C++ pipeline ; jpegdec works , but nvjpegdec doesn’t work fine.

mVideoSourceConvert = gst_element_factory_make("nvjpegdec", "mynvjpegdec");


        this->mTimeoverlay = gst_element_factory_make ("clockoverlay", "myclockoverlay" );
        
        if ( !(this->mTimeoverlay)  ) {
                g_print ("Timeoverlay element could not be created. no overlay.\n");
        
        }
        else{
                g_object_set (G_OBJECT(mTimeoverlay),"time-format",_defs.overlay_time_format.c_str() , NULL ) ;
        }

On TX1 and TX2 , i have crash in build nvjpegdec element.

gst_bin_add_many(GST_BIN(mPipeLine), 
        mAppSrc, mCapsAppSrc,  mVideoSourceConvert , mTimeoverlay,  mTee ,
                mQueueRecord, mVideoRatEnc , mFilterRateEnc , mEncoder, mFilterCapsEncode , mMuxer, mFileSink, NULL);

        ret = ( 
                gst_element_link_many(mAppSrc, mCapsAppSrc, mVideoSourceConvert , mTimeoverlay, mTee ,  NULL) 
             && gst_element_link_many(mTee, mQueueRecord, mVideoRatEnc , mFilterRateEnc ,  mEncoder, mFilterCapsEncode , mMuxer, mFileSink, NULL ) 
        );

… i dont understand why … :/

DaneLLL · November 14, 2017, 1:54am

Hi syd,
SRC pad of nvjpegdec can be video/x-raw(memory:NVMM) and video/x-raw, you may try to link with gst_element_link_filtered ()
[url]GstElement

You shall set video/x-raw to SINK of clockoverlay

_Syd · January 22, 2018, 4:44pm

Hello,

after work on another algorithm , i will back on my nvjpegdec problem.

When i run my program , before to use “gst_element_link_filtered” for link SRC and SINK element, i have crash “Bus Error” when i call the factory_make function :

mVideoSourceConvert = gst_element_factory_make("nvjpegdec", "mynvjpegdec");

So, i can use gst_element_link_filtered for link pipeline elements.

That’s i understand, on TX1 , i can run this with gst-launch

gst-launch-1.0 v4l2src device=/dev/video1 ! "image/jpeg, width=(int)3840, height=(int)2160, pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)30/1" ! nvjpegdec ! fpsdisplaysink video-sink=xvimagesink sync=false -v

For Auvidea/J120 support, TX1 was downgrown on L4T 24.2.1.

_Syd · May 23, 2018, 2:42pm

Hi
I can’t build nvjpegdec with gst_element_factory_make.
When i check the application for linked librairy( i use LDD ). It haven’t libnvjpeg.so in result , only a link for libjpeg.so.

May be it’s a linking problems … how i can add this library or something linked to GstNvJpegDec plugin in CMAKE rules for Gstreamer 1.0/C++ ?!

DaneLLL · May 24, 2018, 8:16am

We have source code of nvgstplayer-1.0 @ https://developer.nvidia.com/embedded/dlc/l4t-sources-28-1

Although it is not in CMAKE rule. FYI.

_Syd · June 1, 2018, 7:06am

I have this source , like Gst-OmX for tegra.

To day, i switch to MMAPI dev for use a see3cam and MJPEG format.

I sorry, i did’nt time for check all library, until another bug.
I already accross NvVideoEncoder TimeStamp issue for MMAPI .

So , i’m waiting for the day fifty off for a TX2 and switch the development to a TX2 / J120. :D
