Linux/AM5718: 1920x1200 Encoding

Hi Margarita,

Is there any way I can confirm frame rate received from camera. I am giving capsfilter as 60. When I encode directly to 720. The encoded file is saying frame rate is 30. Is there any command to know the incoming frame rate correctly ?

Regards,

Hello,

Try with yavta and see what is the fps that it reports.

yavta -c20 -fNV12 -F/dev/null -s1920x1080 /dev/video1

Change the format, resolution depending of your use case.

Hi,

Based on the yavta command's output:

# yavta -c29 -fNV12 -F/dev/null -s1280x720 /dev/video1

It is capturing 720p video at 30fps.

I have modified my upscale and encode command to as follows:

gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 \
! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' \
! vpe num-input-buffers=16 \
! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1200, framerate=(fraction)30/1' \
! ducatih264enc bitrate=10000 \
! filesink location=/home/root/1200_1.h264

Still I am facing same encode issue:

ERROR: from element /GstPipeline:pipeline0/GstDucatiH264Enc:ducatih264enc0: Could not encode stream.
Additional debug info:
gstducatividenc.c(752): gst_ducati_videnc_handle_frame (): /GstPipeline:pipeline0/GstDucatiH264Enc:ducatih264enc0

I even tried in with 29 frame rate. Still same observation.

Hello,

Please check my fist answer.
Add ... ! ducatih264enc level=51 ! ...

Hello,


gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 \
! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' \
! vpe num-input-buffers=16 \
! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)30/1' \
! ducatih264enc level=51 bitrate=10000 \
! filesink location=/home/root/1200_1.h264

Is this working?
I guess you have checked this file:
psdk/board-support/linux-4.14.40+gitAUTOINC+4796173fc5-g4796173fc5/drivers/media/platform/ti-vpe
vpdma.h
where
enum vpdma_max_height {
...
MAX_OUT_HEIGHT_1080,
};


You could try this:
gst-launch-1.0 v4l2src device=/dev/video1 io-mode=4 \
! 'video/x-raw, format=(string)YUY2, width=(int)1280, height=(int)720, framerate=(fraction)30/1' \
! videoscale \
! 'video/x-raw, format=(string)NV12, width=(int)1920, height=(int)1080, framerate=(fraction)30/1' \
! ducatih264enc level=51 bitrate=10000 \
! filesink location=/home/root/1200_1.h264
