Video quality in gstreamer pipeline

[akshim]

Hello,

We have a custom board based on AM5728 SOC with omnivision 0v5640 camera installed on it running linux SDK 6.03 provided by TI. We want to use IVA-HD core in the SOC for video processing. We are using the following gstreamer pipeline to stream the video using IVA-HD core.

gst-launch-1.0 v4l2src device=/dev/video1 ! 'video/x-raw,format=(string)YUY2,width=1280,height=720' ! vpe num-input-buffers=8 ! ducatih264enc ! h264parse ! ducatih264dec ! vpe ! \
'video/x-raw,format=(string)NV12, width=1280,height=1232' ! \
kmssink

We have following queries regarding :

1) The video background looks hazy. We have attached a video for reference. How can we improve the video quality?

2) When we try to run higher resolution (1920x1080), there is lot of frame drop and the video is laggy. How can we support higher resolution?

 

Thanks and Regards, 
Akshi Malhotra
