Software :: Download Helper Screen Capture With Ffmpeg ?
Jul 3, 2011
The sort of add on for Firefox 'download helper' now has a new screen capture thing, in case it won't download the video from a particular site. You click the red button and a purple boundary appears round the video frame. I assume this is the basic function of the thing; it then provides the geometry of the purple frame to the program you've given it to capture the video.
By default the program it uses is 'recordmydesktop'. I've tried using this but get sound from the laptop's internal microphone, not the video. Tried 'pavucontrol' to remedy this but it says (wrongly) that no program is recording, so can't put things right.
So tried using ffmpeg: [URL]
Assume the stuff in curly brackets is what download helper supplies. Sometimes works perfectly but with B.BC. i-player only get the top left hand corner of the video and it is stretched somewhat horizontally.
As the title says, I'm looking for a command to resize on the fly as I capture. My desktop's 1680x1050, but I want to shrink down to say 1280x720.. or other.
Anybody had any success in getting ffmpeg to work as advertised with video capture from a webcam? I really want to convert the webcam output to VP8 or H264, but apparently ffmpeg can't even capture the webcam with a video4linux device.
I'm looking for configuring a Ubuntu box, we need to capture alsa output into ffmpeg with jack or OSS but not pulseaudio, as that tends to glitch badly. We have things working, but we are sort of hacking around in the dark, we play music, but as we aren't linux audio experts ourselves.
As I cannot use svn to download the latest ffmpeg from trunk.Can anyone explain to me how to use proxychains properly so I can download the latest ffmpeg and compile it?
I am watching streaming video via Firefox and Flash player. The data rates are too slow so I am getting choppy audio and video. How do I download the clip so I can play it back later. The video is coming from a tourism web site.
Hey I'm looking for something to grab a section of the screen ... like to allow me to drag a rectangle around a portion of the screen and when I release, capture only that -- in to the clipboard would be fine or at that point to a image file format which I could save on the file system.
i have ubuntu 9 10 i have been searching in the internet but i have not found a solution, my problem is that i cant capture the screen with screen shot key (ptr sc) my keyboard has it under the key home, so in windows i have to use the
I'm having problems with the screen capture utility in Fedora 11. Everytime i capture a screenshot, it looks like this:[url]
I've tried turning off Compiz, but that doesn't do anything. I suspect it may have something to do with the kms (I have an Intel 82855/855GM, which has had issues in beta).
I wonder if there is the possibility of getting to press any key and the F6 for example, Fedora starts up a screenshot, equal to application "form screen capture image" in the menu acessories .. The problem is that if I want to do this I have to be opening up the application every time .. and I like to do with was fast, just by clicking F6 or printscreen for example ..
On my Mac, when I press F2, I am able to take a screen shot of a selected area. Is it possible to assign a hot key to do the same thing on my Ubuntu 10.04 PC?
I need to take a screen capture while an application is running. The application is a touch screen calibration utility and alt-Prnt Scrn does not work when the calibration utility is active. Is there another way for me to capture the screen while the utility is active?
system - screen/mouse/keyboard/hard drive all freeze. if I am in the middle of video or audio, last second of audio loops. I get a terminal screen (attached).
Also, If there is a step by step overall troubleshooting guide,I would appreciate its location. This did not freeze under 10.10, but I have changed wifi card (changed driver) and loaded VirtualBox from oracle (not Ubuntu - VB not running during freeze)) - no other changes.
My screen capture software, shutter and system's default "take screenshot", do not function normal any more. It can only capture the desktop wallpaper, not any other elements on the desktop, nor any other opened windows. It's just like taking an x-ray picture by passing all the other objects/elements/running programs on top of the desktop wallpaper. Any ideas? I am using Fedora 14 64 bit. The screen capture software were working fine, though.
I do quite allot of screen tutorials, and i am always useing this FMMPEG script.ffmpeg -f alsa -ac 2 -i pulse -f x11grab -r 30 -s $(xwininfo -root | grep 'geometry' | awk '{print $2;}') -i :0.0 -acodec pcm_s16le -vcodec libx264 -vpre lossless_ultrafast -threads 0 -y video2.avi.I was just wondering if someone knows a script that i could put in a text file, make it executable and it would ask me what i wanted to save the file as, and it would put that text where "Video2.avi" goes, and then it would just run the normal FFMPEG script.
I need a bash script that auto captures the screen (every 30 sec) and then realize an archive with those screenshots. The script will allow me to quering by user name and date and time framing and if exists a capture archive, it will display a slideshow that presents the captures of specified time.
I'm trying to capture my desktop screen and audio , before I used xvidcap but after upgrading my system I can not use it and also recordmydesktop anymore these APPs hanged when I try to use them.Now I try to use recorditnow via ffmpeg recorder interface , it work properly in recording the desktop but it does not record the sound , so I tried to add below options to its command -f alsa -ac 2 -i hw:0,0 but it just record sound at the beginning and just for 1 second. Also when I try to capture my desktop with ffmpeg directly from command line with below command I face with same problem!!! ffmpeg -f x11grab -s 1024X768 -r 30 -i :0.0 -f alsa -ac 2 -i hw:0,0 ~/out.mpg
I have installed XVidCap Screen Capture. If I record my screen with XVid Cap Screen Capture there is no sound. But if I record with Desktop Recorder there is sound. What is wrong?
I have video capture device "MSI vox USB 2.0", every thing seem to be fine, but none of tv applications show the device, they just show my webcam "/dev/video0"
It's driver is "em28xx" from "v4l2"
I test it with "mythtv, tvtime, xawtv, kdetv, me-tv, v4l2-tool, vlc, mplayer" none of them work detect the device, expect mplayer open a green window with time out message.
The device work fine under windows I test it with vlc-win
I am looking for an screen capture application which auto runs when ubuntu starts up and work without any instructions or clicking capture or anything, = "Some1" ** Turns on the System --> UBUNTU Loads --> the Screen capture Runs--> it takes screen shots with out "Some1"s knowledge// turns off system.... I get home -->> turn on system -->> screen shots r saved.. n um checking em...!!!
On my Windoze machine, I use Replay Media Catcher 4 which runs silently in the background and captures any videos (FLV, AVI, MPG, WMV, etc) on any websites that I happen to go to, and saves them to a folder on my hard drive. Right now, if I want to save a video that I'm wathing from Ubuntu, I have to go to /temp, guess which file it is, and copy it after it downloads fully but before it finishes playing, otherwise Firefox deletes it from /temp right away. This is a pain.
Yes, there are screen motion capture utilities in the Ubuntu Software Center, but they're just screen scrapers that result in low quality copies without any audio. I want something that will actually capture the video stream and save it as a file. Even if it doesn't save all videos automatically like RMC4, and I have to right click on the video to Save As, that would be better than copying it from /temp at the precise exact moment.
I look and look and it doesn't tell its name and whom made it so one can go there and install it on Firefox or whatever.
Have tested many of the addons for FF but none is as good as the one in Debian Elive 2.0 the unstable Elive don't have it. Ubuntu doesn't either.
Searched Debian and Elive sites and used google but fail to find it.
Could it be Shutter program that doesn't advertise itself?
Shutter is supposed to be a good screen grabber.
This screen grabber is activated by pushing the PrtScr button and not by clicking a symbol as the others are. So maybe it is built into Elive itself but not mentioned anywhere?
