Hmm. Anyone already solved this issue with “motion” capturing 1920×1080, i. e. Full HD, streams?

Hrmpft. This is really annoying.
Took me a while, but I’m now rather confident that the issues I was having with the MR3020 as a mjpg-streamer powered streaming webcam server are related to the camera(s) used, not (only) to the tiny box. As you can see below, “only” in daylight the images gets distorted:
As of now I assume that the framerate reported by the camera is responsible for this, as that cam is reporting only 30 fps for all resolutions. It’s working nicely on a SheevaPlug with full-blown Debian, but Sheeva is a different hardware to the MR3020 (and 3 to 5 times as expensive per box); I might try a Dockstar as the host for this cam, but time will tell.
Just FTR, with a quickly ordered Logitech C270 HD, the MR320 is serving just nicely as a streaming webcam server (cam reports 5 and 10 fps for 1280×720, I choose 5, which is sufficient for now):
Hmm. Previously, I build two nice webcam-servers out of Fonera 2.0g boxes (German posts: 1 & 2). cpuinfo of the Foneras is as follows:
root@cam-serv3:~# cat /proc/cpuinfo system type : Atheros AR2315 processor : 0 cpu model : MIPS 4KEc V6.4 BogoMIPS : 183.50 wait instruction : yes microsecond timers : yes tlb_entries : 16 extra interrupt vector : yes hardware watchpoint : no ASEs implemented : shadow register sets : 1 core : 0 VCED exceptions : not available VCEI exceptions : not available
There I run two jobs, for /dev/video0 and /dev/video1, of mjpg_streamer -i input_uvc.so -f 10 -r 960x720 ..., which results in this top output:
Mem: 19836K used, 10080K free, 0K shrd, 1140K buff, 6096K cached CPU: 19% usr 11% sys 0% nice 1% idle 0% io 31% irq 34% softirq Load average: 2.57 2.51 2.45 PID PPID USER STAT VSZ %MEM %CPU COMMAND 1518 1064 root R 8732 29% 33% mjpg_streamer -i input_uvc.so -d /dev 1517 1060 root R 8572 29% 26% mjpg_streamer -i input_uvc.so -f 10 - 1065 1064 root R 8732 29% 20% mjpg_streamer -i input_uvc.so -d /dev 1061 1060 root S 8572 29% 7% mjpg_streamer -i input_uvc.so -f 10 - 1577 1520 root R 1960 7% 6% top -d 2 1519 933 root S 1996 7% 1% /usr/sbin/dropbear -p 22 1064 1058 root S 8732 29% 0% mjpg_streamer -i input_uvc.so -d /dev 1058 1 root S 8732 29% 0% mjpg_streamer -i input_uvc.so -d /dev 1067 1064 root S 8732 29% 0% mjpg_streamer -i input_uvc.so -d /dev 1060 1056 root S 8572 29% 0% mjpg_streamer -i input_uvc.so -f 10 - 1056 1 root S 8572 29% 0% mjpg_streamer -i input_uvc.so -f 10 - 1066 1060 root S 8572 29% 0% mjpg_streamer -i input_uvc.so -f 10 - 1055 1 root S 1976 7% 0% udhcpc -t 0 -i ath0 -b -p /var/run/at 520 1 root S 1972 7% 0% udhcpc -t 0 -i eth0.1 -b -p /var/run/ [...]
Recently I joined the MR3020 hype, them being quite similar to the Fonera 2.0g systems, i. e. Atheros-based, supported by OpenWR, rather cheap (<30 EUR) and with USB; only drawback is the ridiculously small on-board Flash:
root@cam-serv5:~# cat /proc/cpuinfo system type : Atheros AR9330 rev 1 machine : TP-LINK TL-MR3020 processor : 0 cpu model : MIPS 24Kc V7.4 BogoMIPS : 265.42 wait instruction : yes microsecond timers : yes tlb_entries : 16 extra interrupt vector : yes hardware watchpoint : yes, count: 4, address/irw mask: [0x0000, 0x0280, 0x05d0, 0x0630] ASEs implemented : mips16 shadow register sets : 1 kscratch registers : 0 core : 0 VCED exceptions : not available VCEI exceptions : not available
But to my big disappointment, running even only one process of mjpg_streamer, /usr/bin/mjpg_streamer --input input_uvc.so --device /dev/video0 --fps 1 --resolution 1280x720 ..., seems to max the system out, and anything above 1 fps, I tested 2, 5, 10, gives quite chopy images, distorted in odd ways. top says:
Mem: 25868K used, 3308K free, 0K shrd, 1412K buff, 5392K cached CPU: 0% usr 0% sys 0% nic 97% idle 0% io 0% irq 0% sirq Load average: 0.06 0.11 0.11 1/41 1542 PID PPID USER STAT VSZ %VSZ %CPU COMMAND 1514 1 root S 24424 84% 0% /usr/bin/mjpg_streamer --input input_ 1541 1431 root R 1496 5% 0% top -d 2 1430 1362 root S 1216 4% 0% /usr/sbin/dropbear -P /var/run/dropbe 1431 1430 root S 1504 5% 0% -ash 592 1 root S 1504 5% 0% /sbin/syslogd -C16 1140 1 root S 1504 5% 0% /sbin/udhcpc -t 0 -i wlan0 -b -p /var ...
So, it does not seem to be a CPU limitation; the CPU should be even more powerful than the Fonera’s, and the minor increase in resolution, 1280×720 instead of 960×720, should be compensated by far by the two USB cams served by the Fonera. Any opinions or tips?
Schon cool: »copy link« im Kontextmenü auswählen, ggf. das /#! wegwerfen, und schon stellt ein kleines lokales Plugin gemäß »Ottos« Blogeintrag einen Tweet samt Anhang dar — aus https://twitter.com/wusel/status/197085455915814912 wird:

DAS ist letztlich der Grund, warum ich von SPHPBLOG auf WordPress mit einer fscking Datenbank gewechselt bin :-) (Aber warum wird »Wordpress« oben zu »WordPress«?)

What’s the suggested plugin, or shall I use multiple, for properly integrating my now WordPress-powered blog with Twitter and Facebook?
I want to be able to selectively post to Twitter and/or Facebook, and want to record external responses (replies/retweets on Twitter, comments on Facebook) in WordPress as well. Posting comments on FB-derived ones in WP will still break the discussion, but that I intend to think about after some trial period.
Furthermore I’m looking for a different Android-App than the one called ‘WordPress’ in the MarketPlayStore, since this one seems to break EXIF data on image upload :-(
So, my dear followers: Any hints appreciated on #tw and FB as well as on the blog :-)
[exif id=”9593″]… anstatt des Android-Clients. Bleiben da wenigstens die EXIF-Tags bestehen und werden die richtigen in die DB übernommen?
[Edit] Augenscheinlich ja. Demnach hat mich die EXIF-strippende WordPress-App für Android nun rund einen Tag auf Hexenjagd geschickt, warum denn keines der angeblich ach-so-geilen Plugins bei mir funktioniert. Su-per. #tw #fb [/EDIT]
… might never become frieds :-(
P1010411.JPG exceeds the maximum upload size for this site.
Holy shit, this is my bloody site and I do want to upload this 5.7 MB image. Gnampf! #tw

I’m really a bit confused right now. I want to use apache2’s mod_rewrite to link from the previous blog (powerded by locally hacked SPHPBLOG) to my new, shiny, WordPress-driven one. Therefore old links like /index.php?entry=entry120414-202918 need to be redirected to http://v2.blogdoch.net/2012/04/ …
So, what I tried was:
RewriteRule ^/index.php\?entry=entry([0-9][0-9])([0-9][0-9])([0-9][0-9])-202918 http://v2.blogdoch.net/20$1/$2/ [R,L]
Above does not fire at all. The followings does, but a bit unexpected:
RewriteRule ^/index.*[^=](.*)$ http://v2.blogdoch.net/old/$1 [R=302,L]
I call "Location: http://v2.blogdoch.net/old/?entry=entry120414-202918” unexpected on a "wget http://blogdoch.net/index.php?entry=entry120414-202918” here. WTF is going on? I’d expect “entry120414-202918“, but not everything after, and including, “?” — is my regexp foo that rusty?!
Any hints appreciated ;)
