Hello Jetson team and developers,
I asked some questions but I don’t think my intention have been well communicated.
so I reupload. I am sorry to bother you.
I am using tx2 and gstreamer to stream video
and I am investigating about encoding/decoding performance on tx2
below infomation is part of table that i saw on the blog.
encoder : 4Kp60, (3x) 4Kp30, (8x) 1080p30
decoder : (2x) 4Kp60
I guess some numbers indicate resolutions and fps but I couldn’t understand (3x),(8x),(2x). what is that mean?
also I get similar things when I use pipeline like blow.
gst-launch-1.0 rtspsrc location=rtsp://169.000.00.00:8554/test ! queue ! rtpvp8depay ! omxvp8dec ! nvvidconv ! nvoverlaysink overlay-x=400 overlay-y=600 overlay-w=640 overlay-h=480 overlay=1 & gst-launch-1.0 rtspsrc location=rtsp://169.000.00.00:8554/test ! queue ! rtpvp8depay ! omxvp8dec ! nvvidconv ! nvoverlaysink overlay-w=640 overlay-h=480 overlay=2
and I got message
NvMMLiteOpen : Block : BlockType = 278
NVMEDIA: Reading vendor.tegra.display-size : status: 6
NvMMLiteBlockCreate : Block : BlockType = 278
Allocating new output: 1024x768 (x 11), ThumbnailMode = 0
OPENMAX: HandleNewStreamFormat: 3605: Send OMX_EventPortSettingsChanged: nFrameWidth = 1024, nFrameHeight = 768
in the message there is “Allocating new output: 1024x768 (x 11)” .
I know 1024x768 is resolution of my video but what is (x11)?
