Ahoj,
potrebuju ziskat fotku z webove kamery Ubiquiti airCam (http://wifi.aspa.cz/sitova-ip-kamera-ubiquiti-aircam-1-mpix-1280x800-hdtv-720p-30-fps-1x-lan-napajeni-poe-z104320/). Na pocitaci s Ubuntu 12.10 pouzivam
ffmpeg -i rtsp://IP.AD.RE.SA:554//live/ch00_0 -y -f image2 -sameq -t 0.0001 image.jpga bez problemu ziskam fotku.
Problem je u OpenWrt. Mam verzi 10.03.1 backfire (oficialni obraz z webu, sam jsem ho nekompiloval), architektura x86. Balicek ffmpeg (http://downloads.openwrt.org/backfire/10.03.1/x86_generic/packages/ffmpeg_0.5.4-2_x86.ipk)take z webu OpenWrt.
Pokud pustim stejny prikaz pod OpenWrt, dostanu:

Usually that means that input file is truncated and/or corrupted.

Nevite, kde je problem? Nebo cim pripadne vytahnou fotku z video streamu (jeste potrebuju vlozit do fotky text - to mi na pc pomoci ffmpeg funguje).
Podle VLC leze z kamery: (http://db.tt/duGVMfFY)
Diky za pomoc :-)

no tak když už diskutím tak dám taky něco k dobru. V podstatě mám zkušenost že je třeba se přihlásit prakticky něco jako jmeno:heslo@IP.AD.RE.SA atd.Ty ubiquti nepožadují login?
-
Tahle je bez hesla. Uplne stejny prikaz bez hesla mi na PC funguje, na OpenWrt ne.
-
Nejdříve bych vyzkoušel ffmpeg na poslední stabilní verzi této distribuce. FFmpeg je tam zkompilován s odlišnými configure argumenty a je tam v odlišné verzi. Zkuste tedy 12.09 nebo poslední trunk, zda se ta issue projevuje i tam.
-
Zkusil jsem ffmpeg z trunku http://downloads.openwrt.org/snapshots/trunk/x86/packages/
Bylo potreba doinstalovat balicky:
http://downloads.openwrt.org/snapshots/trunk/x86/packages/ffmpeg_0.11.2-2_x86.ipk
http://downloads.openwrt.org/snapshots/trunk/x86/packages/libffmpeg-full_0.11.2-2_x86.ipk
http://downloads.openwrt.org/snapshots/trunk/x86/packages/libbz2_1.0.6-1_x86.ipkostatni si opewrt dotahlo samo z verze backfire.
Instalace probehla dobre:

Mate nejaky napad? OpenWrt aktulizovat nemuzu, k zarizeni nemam ted fyzicky pristup. Jeste zkusim ffmpeg z 12.09.
-
Tak ffmpeg z 12.09 ma uplne stejny problem :'(
-
Ahoj mám úplně stejný problém povedlo se ti to nějak vyřešit? diky
-
Zatim jsem to testoval jen na x86 s Ubuntu, tam uz mi ukladani videa a deleni na soubory funguje.
Na OpenWRT se porad chystam.
