PROCESSOR-SDK-J722S: [TDA4AEN] There is no v4l2-enc driver

Hi Yongsig,

Because of this I assume you are not able to run any GStreamer pipeline to confirm functionality, is that correct? I will create an out of box Vision Apps image and see if I can replicate your results.

Can you try this simple pipeline and let me know your results:
gst-launch-1.0 videotestsrc pattern=ball num-buffers=700 ! video/x-raw, format=NV12, width=1920, height=1080, framerate=30/1 ! v4l2h264enc ! h264parse ! fakesink

Thank you,
Sarabesh S.

Hi Sarabesh

Thanks for your help.

I'll use v4l2-enc directly with ioctt(), not GStreamer.

--> It doesn't work. I'll share the log as below.

Hello,

Not sure if your pipeline is copied correctly because "num-buffers" is spelled incorrectly. Although, I will check on 10.0 Linux+RTOS to confirm. Please give me a day to test this. 

Thanks,

Hi Sarabesh

Sorry, I don't know if there is a typo.

I tried again, and it looks like it works.

root@j722s-evm:~# gst-launch-1.0 videotestsrc pattern=ball num-buffers=700 ! video/x-raw, format=NV12, width=1920, height=1080, framerate=30/1 ! v4l2h264enc ! h264parse ! fakesink

But I want to use wave5-enc in PSDK10.0 as I used in PSDK 9.2.

It appears functionality wise, the encoder is working on your setup. If you're able to run gstreamer pipelines using hardware acceleration with the v4l2h264enc element then you are using the wave521CL encoder.

Thanks,
Sarabesh S.

Hi Sarabesh

I'm sorry I don't understand that I can use the wave521CL encoder.

It looks like the only driver that is registered in Linux is wave5-dec as of now.

root@j722s-evm:~# v4l2-ctl --list-devices
wave5-dec (platform:30210000.video-codec):
        /dev/video0
        /dev/video1

e5010 (platform:fd20000.e5010):
        /dev/video2

Also, I know e5010 is for JPEG, not H264.

What driver name should I put instead of 'device_name'?

int32 fd = open(device_name, O_RDWR | O_NONBLOCK, 0);

Let me look into this and try to replicate. Haven't had a chance to build the 10.0 Vision Apps image yet.

Thanks,
Sarabesh S.

Hi Sarabesh

OK. I appreciate your help.

If you have an update, please let me know.

Best regards

Hi Yongsig, 

Yes, I will let you know.
