That was the only way I could get multiple WiFi adapters working, would be curious to know if you found another method. Sounds like a very interesting project you have!

Yes the board has a hub built into it. I had a friend in Brazil that works on sat's make it for me. I was able to bring up 3 rtl8187 adapters. All the same chips. I honestly had no issues at all, even when I was still using the summit. I just patched the driver and IW to enable certain features and once I did that had no issues. Its a fun project for sure, has already proven very useful in some audits. JL On Sat, Apr 9, 2011 at 5:40 AM, Paul Nolan <pa...@id...> wrote: > > > What do you mean by what am I running?

hey steven, i was just wondering about how you got those numbers this gstreamer pipeline: gst-launch -v videotestsrc ! video/x-raw-yuv, width=640, height= 480 ! TIVidenc1 codecName=h264enc engineName=codecServer ! udpsink host= <host IP> port=5000 took up 90% of my cpu. when i ran the same on 320X240 it took 30% of my cpu. |

E-con 3.2MP camera, overo fire FE. gst-launch -v v4l2src ! video/x-raw-yuv,width=640,height=480,framerate=30/1 ! TIVidenc1 codecName=h264enc engineName=codecServer ! udpsink host=192.168.80.110 port=10000 Considering gst-launch -v videotestsrc ! video/x-raw-yuv, width=640, height=480 framerate=30/1 ! fakesink sync=false silent=true takes up 90% of the CPU by itself, I don't think videotestsrc is a good test of CPU usage.

Another data point for video streaming from a gumstix. The sensor is a new one, mt9p031. The gumstix ISP is doing more work on this then the Caspa since the raw sensor data is 2560x1920 Bayer instead of 640x480 Bayer. So the images are both converted to YUV and getting resized by the ISP. I'm testing with an Overo Tide running at 720 MHz. Kernel 2.6.32-psp with 'task-gstreamer-ti' and my driver added to a slimmed down omap3-console-image. I am running this command on the gumstix gst-launch v4l2src ! video/x-raw-yuv, width=640, height=480 ! smokeenc ! udpsink host=192.168.10.4 port=4000 And this on the workstation (192.168.10.4) gst-launch udpsrc port=4000 ! smokedec ! autovideosink Gumstix top top - 19:34:34 up 1:43, 2 users, load average: 0.06, 0.07, 0.07 Tasks: 63 total, 1 running, 62 sleeping, 0 stopped, 0 zombie Cpu(s): 12.5%us, 0.9%sy, 0.0%ni, 86.5%id, 0.0%wa, 0.1%hi, 0.0%si, 0.0%st Mem: 472404k total, 107512k used, 364892k free, 5780k buffers Swap: 0k total, 0k used, 0k free, 63248k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1100 root 20 0 61368 7464 4096 S 12.8 1.6 1:08.35 gst-launch-0.10 1107 root 20 0 2344 1084 896 R 0.2 0.2 0:00.87 top 949 root 10 -10 22832 9.9m 6284 S 0.1 2.2 0:13.17 enlightenment 974 root 20 0 3128 756 604 S 0.1 0.2 0:04.88 ipaq-sleep 1 root 20 0 1560 580 516 S 0.0 0.1 0:04.12 init 2 root 20 0 0 0 0 S 0.0 0.0 0:00.00 kthreadd 3 root 20 0 0 0 0 S 0.0 0.0 0:00.01 ksoftirqd/0 root@overo:~# lsmod Module Size Used by bufferclass_ti 3583 0 omaplfb 8420 0 pvrsrvkm 126408 2 bufferclass_ti,omaplfb sdmak 3962 0 lpm_omap3530 7007 0 dsplinkk 129965 3 lpm_omap3530 cmemk 22903 0 mt9p031 12819 1 Pictures look good. I don't have good control of frame rate in the driver yet so not sure what I'm really getting. Working on that ;-) Is there a way to get gstreamer to tell me what I'm really receiving for frame rates on the workstation? Scott -- Sent from my Linux box |
