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.
So far my command is code...
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.
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.
Code:
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.

I'm looking for the option that will let you resize the width of a video during conversion.
In ffmpeg2theora it's
ffmpeg2theora -x ###
that option will let you change the width (or the height), and the program will properly scale the height (or width) automatically.
Is this possible in ffmpeg or do you have to figure out the scale manually?
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?
View 9 Replies View RelatedI 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.
View 3 Replies View RelatedOn 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'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

View 1 Replies View RelatedJust got Studio 9.10 running and the RT kernel installed. I have a Prescott P4 3.2ghz (hyperthreading) and i encountered what looks like a common freeze problem. I am guessing my cpu will not be supported in the RT kernel since it is pretty old now.I added nosmp acpi=off during boot at the Grub2 menu and it booted fine and I was able to capture some video great.
My questions is, if I remove the smp support by using the nosmp option, do I still benefit from the RT kernel or would I do just as well with the generic kernel I have installed?Eventually I will upgrade do a new system board and processor but for now I just got some life back in this one by switching to Linux
I have investigated loads and loads of options and haven't really yet come across what I need.
I wish to stream the microphone input from a PC using Lucid to another PC also using Lucid on the same network. I don't care about the quality, however, latency is really important. I hope to use it to monitor the cries of my baby daughter, so the lower the latency the better.
I have tired various options:
- FFserver and FFmpeg - latency of over 30 seconds
- VLC - couldn't get it to work with my mic and maxes out the CPU
- ssh server 'cat /dev/dsp > /dev/dsp' - latency of around 5 seconds by audio keeps breaking up with huge delays
- icecast2 and darkice - latency of around 7 seconds but no audio breakups
I've been reading on maybe using PulseAudio to stream the input, but I am not sure if it will work or not...
how to get near real-time streaming audio? As I said, it is the realtime, not the quality that is important...
I am not able to start JACK in realtime mode. This is a bummer. here is the error message I get:
p, li { white-space: pre-wrap; } 11:58:20.745 Patchbay deactivated.
11:58:20.746 Statistics reset.
11:58:20.812 ALSA connection graph change.

is there a realtime or low-latency kernel in a repository somewhere for OpenSUSE 11.4? I know I can just compile a rt kernel, but that's a bit tedious and I'd like to avoid it if possible.

What Ubuntu Sees:
I'm still rather new to Linux. I'm running a computer on a 1080p television, using HDMI as the connection cable. On a fresh boot of Ubuntu (and Puppy), the screen fits perfectly, without any black areas or cropping of the edges. But, without the Nividia driver, it also has no sound, as the sound is routed through the video card via the HDMI. When I do install the drivers, the screen depth suddenly stops working. It either has major areas that are black and not used, or the edges are so heavily cropped off that it's close to impossible to use it. I remember the older Nvidia drivers used to have a function that I could use a GUI to resize the screen manually, but I can't find that feature in the current drivers.
