do deinterlace with TX1

Echo1900 · July 21, 2017, 3:07am

I try to use TX1 to decode field frame. Can TX1 do deinterlace?

DaneLLL · July 21, 2017, 3:17am

We have it supported. Please try gstreamer or MM APIs.

Echo1900 · July 21, 2017, 3:22am

Could tell the gstreamer plugin name? Ifind “deinterlace”. Is it is hard “deinterlace”.

DaneLLL · July 21, 2017, 3:26am

Hi Echo1900, it is done in decoder automatically.

Echo1900 · July 21, 2017, 3:32am

But now I find when I use 720X576I25 stream, decoder out frame rate is 50.What canbe the reason

DaneLLL · July 21, 2017, 3:39am

Hi Echo1900, please share the video file and command to reproduce the issue.

Echo1900 · July 21, 2017, 3:56am

Dear DaneLLL:
I use code, not cmd, I put the code?

DaneLLL · July 21, 2017, 5:58am

Yes, please share steps to reproduce the issue on r24.2.1.

Hi Echo1900, please try a full gstreamer pipeline
gst-launch-1.0 filesrc location=test.ts ! tsdemux ! h264parse ! omxh264dec ! nvoverlaysink

If the issue is still present, could you upload it to dropbox or google drive so that we can download?

Echo1900 · July 23, 2017, 2:51am

Hi DaneLLL,

 Thanks for your quick reply.I tested your cmd, get print as list.
 I also tried <b>'gst-launch-1.0 udpsrc port=12340 ! tsdemux ! h264parse ! omxh264dec ! nvvidconv ! omxh264enc ! mpegtsmux ! udpsink host=192.168.1.20 port =12340'</b>

I tried ‘ffmpeg’ on TX1, ‘ffmpeg’ out is OK.

HI DaneLLL，
We now use Jetpack Version 2.3.1:Linux for Tegra 24.2.1,Multimedia API v24.2.1.
So what can be the reason.

DaneLLL · July 26, 2017, 1:28am

Hi Echo1900,
We have also verified Multimedia API v24.2.1 and it works well.

Now I’am testing!!!

haihoangsoftware · March 7, 2019, 4:08am

Hi.

Does gstreamer support directly deinterlace video input from CSI-2 port?

haihoangsoftware · March 10, 2019, 4:20pm

TX1 seem not support deinterlace and so we have to deinterlace by our own software.

DaneLLL · March 11, 2019, 1:29am

Hi,

We do not support it.
