Byla vydána Mageia 5.1. Jedná se o první opravné vydání verze 5, jež vyšla v červnu loňského roku (zprávička). Uživatelům verze 5 nepřináší opravné vydání nic nového, samozřejmě pokud pravidelně aktualizují. Vydání obsahuje všechny aktualizace za posledního téměř půldruhého roku. Mageia 5.1 obsahuje LibreOffice 4.4.7, Linux 4.4.32, KDE4 4.14.5 nebo GNOME 3.14.3.

Joinup informuje, že Mnichov používá open source groupware Kolab. V srpnu byl dokončen dvouletý přechod na toto řešení. V provozu je asi 60 000 poštovních schránek. Nejenom Kolabu se věnoval Georg Greve ve své přednášce Open Source: the future for the European institutions (SlideShare) na konferenci DIGITEC 2016, jež proběhla v úterý 29. listopadu v Bruselu. Videozáznam přednášek z hlavního sálu je ke zhlédnutí na Livestreamu.

Máte rádi svobodný software a hardware nebo se o nich chcete něco dozvědět? Přijďte na 135. sraz spolku OpenAlt, který se bude konat ve čtvrtek 8. prosince od 18:00 v Radegastovně Perón (Stroupežnického 20, Praha 5). Sraz bude tentokrát tématický. Bude retro! K vidění budou přístroje jako Psion 5mx nebo Palm Z22. Ze svobodného hardwaru pak Openmoko nebo čtečka WikiReader. Přijďte se i vy pochlubit svými legendami, nebo alespoň na pivo. Moderní hardware má vstup samozřejmě také povolen.

Dotaz: Problém s programem Motion

Problém s programem Motion
Přečteno: 380×
Příloha:
Zdravím Vás všechny, potřeboval bych snímat obrázky z webkamery pomocí programu Motion, který dokáže vyhodnocovat pohyb. Funguje to, až na jednu věc, že mi to obrázky ukládá se špatným obsahem. Viz přiložený obrázek ukazka.jpg, polovina snímku je nějak zakostičkovaná. Zkusil jsem vyfotit snímek pomocí programu Fotobudka Cheese. Tam žádný problém není (ale neumí to zase snímat pohyb). Příkaz lsusb mi vypíše řádek Bus 002 Device 005: ID 0c45:60b0 Microdia Genius VideoCam Look. Konfigurace programu motion v motion.conf je:

(default: 8) # E.g. if your videodevice supports both V4L2_PIX_FMT_SBGGR8 and # V4L2_PIX_FMT_MJPEG then motion will by default use V4L2_PIX_FMT_MJPEG. # Setting v4l2_palette to 1 forces motion to use V4L2_PIX_FMT_SBGGR8 # instead. # # Values : # V4L2_PIX_FMT_SN9C10X : 0 'S910' # V4L2_PIX_FMT_SBGGR8 : 1 'BA81' # V4L2_PIX_FMT_MJPEG : 2 'MJPEG' # V4L2_PIX_FMT_JPEG : 3 'JPEG' # V4L2_PIX_FMT_RGB24 : 4 'RGB3' # V4L2_PIX_FMT_UYVY : 5 'UYVY' # V4L2_PIX_FMT_YUYV : 6 'YUYV' # V4L2_PIX_FMT_YUV422P : 7 '422P' # V4L2_PIX_FMT_YUV420 : 8 'YU12' v4l2_palette 3

Nie vsetky USB kamery maju input na porte 8. Skus tam dat cisla postupne od 0, ci sa to na nejakom nechyti ...

@Lukas, odkial mas taku zazracnu schopnost citat takto vyformatovane cfg? :) pre nas ostatnych by mozno pomohol vystup z:
egrep -v '^#|^$|^\;' /etc/motion/motion.conf
USB kamera (ak podporuje MJPG) by mala bezat s jednoduchym, napr.:
...
videodevice /dev/video0
framerate 5
width 640
height 480
...
Vela zdaru.

Omlouvám se za nečitelný zápis konfiguračního souboru.

Zkusil jsem tedy změnit v motion.conf (jak mi radil Lukáš) hodnotu input na 0, vycházely mi z toho stejné snímky jako při input 8. Když jsem změnil input 1, tak mi to nešlo vůbec.

Zkusil jsem tedy v motion.conf smazat vše a nechat pouze

videodevice /dev/video0

framerate 5

width 640

height 480

jak mi radil Loso, snímky mi z toho lezou úplně stejně blbě. Terminál mi po té vypisuje toto:

Vzdy ked je nejaky problem s USB kamerou tak skusam toto:

1. zmenit input (toto nezabralo)
2. zmenit paletu:
[1] Config palette index 8 (YU12) doesn't work.
[1] Supported palettes:
[1] 0: S910 (S910)
[1] 1: BA81 (BA81)
[1] Selected palette BA81
3. zmenit rozlisenie:
[1] Adjusting resolution from 640x480 to 160x120.
Skus tam este setnut tu druhu paletu a pohrat sa s rozlisenim. Ked ti to fungoje cez to GUI, tak tam skus dat parametre z toho softu. Idealne ak by si este testol mplayer. Mplayer vie byt vcelku verbose a potom staci len copy/paste do configu.

FYI: USB kamery su najvacsia katastrofa co moze byt. Vacsinou maju implenetovany kod "len aby to slo". Uplne bezne kamery posielaju hluposti, ked sa nepouzije presne ten jeden profil, co implementoval vyrobca ...

odporucam zistit, co ten zazrak vlastne poskytuje, to by bolo mozne vidiet napr. z vystupu:
v4l2-ctl --list-formats-ext
a z toho usudit co dat do samotneho motion cfg.

zaujimava kamera, tento "kamera dedusko" zrejme na linuxe svoj zenit asi nezazil/nezazije, vie ju aspon vlc otvorit korektne? ja som nedavno recykloval suflikove zasoby divnych webkamier a vacsinu z nich som cez vlm transkodoval na MJPG, ktoremu uz motion rozumie dopohody.

precitat si vystup, ci by nepomola ina :v4l2-chroma=??? napriklad, mozno ma uplne iny psych. problem, ak nic tak :( tak roztocit za ten USB kabel a zahodit hodne daleko...

Tak tento příkaz video spustil, není to ideáln, ale je to na stejné úrovni jako ta Fotobudka Cheese, takto by mi to aji stačilo, jak to udělat aby to stejně jelo i v Motion? Jinač to co to píše jsem vložil do vystup.txt, který přikládám.

OK, v jednom terminali pustit:
$ cvlc v4l2:// :v4l2-dev=/dev/video0 :v4l2-width=640 :v4l2-height=480 --no-audio --sout '#transcode{vcodec=MJPG,fps=5,width=640,height=480}:std{access=http{mime=multipart/x-mixed-replace;boundary=--7b3cc56e5f51db803f790dad720ed50a},mux=mpjpeg,dst=:8123/cam.mjpg}' --http-host=127.0.0.1
VLC by malo zacat kameru streamovat na url http://127.0.0.1:8123/cam.mjpg, ta by mala byt vidno aj napriklad vo firefoxe, ak sa transkodovanie nevysype na nejakej "palete" apod.

V druhom terminali: do motion cfg potom uz len chytat onu url:
...
text_left CAM 1
target_dir /var/motion/cam1
netcam_url http://127.0.0.1:8123/cam.mjpg
...
text_left, text popisujuci priamo v obraze danu kameru..."CAM 1", "cokolvek" target_dir, miesto kde motion bude ukladat videa/fotky a musi byt zapisovatelny pre motion

Vela zdaru.
