video streaming

[brandonhead]

Yup, the -y option gave a segfault for me too!

Let me know if you solve it as I would like to use the smaller laptop camera too.

The older version PKG_REV 148 work more stable with "-y" option

Hi Guys.. I'm waiting on my VoCore and going to be trying out video streaming over wifi too.
This is the camera I have on order.

USB Mjpeg - hopefully will work. Might be a few weeks till it all arrives/and have time to test this out. Will post info as and when

I tested 140 rev and 148 rev for working with "-y" option. It's working fine. But used many res:

I tested it with usbtv kernel module for videograbber EasyCap (very bad quality due to high load of processor)
Link to packege mjpg-streamer-r148, I included only input_uvc and output_http plugin:

Test with this command:
mjpg_streamer -i "input_uvc.so -r 720x480 -f 5 -y" -o "output_http.so -n -w /www/webcam/"

Finally VoCore arrived!
I used mjpeg-streamer r148 and it works! I have made some benchmarks with a usb webcam from a death notebook and with vocore connected in STA mode (maybe this could be a bottleneck).

BENCHMARKS:

1) resolution 160x120 (very fluid streaming)
Command: /usr/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -resolution 128x96 -y" -o "output_http.so -www /www/webcam" -b
FPS analysis: 15 fps

CPU usage: 20-30%

2) resolution 320x240 (pretty good streaming)
Command: /usr/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -resolution 384x288 -y" -o "output_http.so -www /www/webcam" -b
FPS analysis: 13 fps

CPU usage: 40-60%


3) resolution 640x480 (very, very, (very) slow streaming)
Command: /usr/bin/mjpg_streamer -i "input_uvc.so -d /dev/video0 -resolution 640x480 -y" -o "output_http.so -www /www/webcam" -b
FPS analysis: 4 fps

CPU usage: 100%

Soon I'll test a usbip environment

Hey guys - working off he dock I am getting very smooth 30fps 640x480 over wifi. Jut followed Vongers Blog... ?
Could it be your camera is creating/using different Mjpeg?

Our camera without jpeg. Streamer must convert yuv in jpeg on the fly and this use additional cpu power.

I too was trying with a tiny cam salvaged from a dead laptop. It seems that while these are pretty tiny they are normally pretty awful.
I bought the Lifecam3000 for cheap on ebay and it streams smooooothly and gives a great picture. It's quite small too.

I would recommend this for the VoCore streaming instead of swimming uphill with a salvage laptop camera.
