See FFmpeg: The ultimate Video and Audio Manipulation Tool for a good and up-to-date usage guide and more information on using presets. Other Junk: I'm not sure what browsers will support Vorbis in the MP4 container format. Libx264 ignores -bt 345k and -threads 0 is now automatically applied so those options are superfluous. Unlike on a Windows computer, FFmpeg is easiest to install as part of the Homebrew package manager, which you can quickly install via Terminal: Go to in your browser. Copy the code below the 'Install Homebrew' heading by selecting it and then pressing ⌘ Command + C.
Releases Approximately every 3 months the FFmpeg project makes a new major release. Between major releases point releases will appear that add important bug fixes but no new features. Note that these releases are intended for distributors and system integrators. Users that wish to compile from source themselves are strongly encouraged to consider using the development branch (see above), this is the only version on which FFmpeg developers actively work.
The release branches only cherry pick selected changes from the development branch, which therefore receives much more and much faster bug fixes such as additional features and security patches. FFmpeg 4.1 'al-Khwarizmi' 4.1 was released on 2018-11-06. It is the latest stable FFmpeg release from the 4.1 release branch, which was cut from master on 2018-11-02. It includes the following library versions: libavutil 56. 22.100 libavcodec 58. 35.100 libavformat 58.
20.100 libavdevice 58. 5.100 libavfilter 7. 40.101 libswscale 5.
3.100 libswresample 3. 3.100 libpostproc 55. FFmpeg 2.8.15 'Feynman' 2.8.15 was released on 2018-07-16. It is the latest stable FFmpeg release from the 2.8 release branch, which was cut from master on 2015-09-05. Amongst lots of other changes, it includes all changes from ffmpeg-mt, libav master of 2015-08-28, libav 11 as of 2015-08-28. It includes the following library versions: libavutil 54.

Introduction to Linux - A Hands on Guide This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter. For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own. To receive this Complete Guide absolutely free.
Code: This program allows one to 'record' your desktop, or even stream it, with the help of VLC. It also includes some helper 'record your screen capture' and setup utilities.
In order to use those you'll want/need the java JRE installed on your system first. It also includes a free, general purpose, open source directshow desktop/screen source capture filter. You can use this with any (directshow compatible) program to capture or stream, like VLC. It also includes a directshow source capture filter device for recording 'what you hear' in windows 7/vista. See and some utilities for it. Installation Download installer and run, from (sorry it's on sourceforge: github limits their disk usage space and I'm hitting up against the limit) NB that you may need need to install the MSVC 2010 runtime distro first, if it's not already installed on your machine (typically, it already is). Usage Use some helper programs provided in Start menu - Programs - Screen Capture Recorder - XXX Or use any 3rd party program that can read from a Directshow Capture Device (ex: VLC).
VLC example: ffmpeg example (requires ffmpeg 32 bit - 64 bit is available upon request): $ ffplay -f dshow -i video='screen-capture-recorder' or $ ffmpeg -f dshow -i video='screen-capture-recorder' -r 20 -t 10 screen-capture.mp4 # -t 10 for 10 seconds recording or combine it with recording 'what you hear' audio vista/windows 7 (using ffmpeg in this example): $ ffplay -f dshow -i audio='virtual-audio-capturer':video='screen-capture-recorder' # this example gives feedback be careful. The audio device name can be other dshow audio devices, as well. Avisynth also works with it. Add it to a filter graph using graphedit, then use DirectShowSource as your input source with that graphedit filename specified. Gstreamer works, as well: $ gst-launch.exe dshowvideosrc device-name=screen-capture-recorder! Directdrawsink I've even had Skype accidentally use it, thinking it was my webcam. Let me know if you want an easier way made for it for anything.
Configuration By default, it captures the 'full screen' of the main desktop monitor (all windows, overlapping, there). To configure it differently, run the provided 'configuration setup utilities' or adjust registry settings before starting a run (advanced users only): HKEYCURRENTUSER Software osscreencapture with DWORD keys respected of: startx, starty, width, height, fps # monitornumber, hwndtouse, showmouse # unimplemented, but can be created if there is any request for them: ex: see incoming.reg (though NB that those values are in hex, so editing that file is a bit tedious). If any value registry value is set to 0, that means 'not set' so it uses the default for that value. Trouble shooting/Feedback/Questions it's too slow!
Run the 'benchmark your capture speed' utility to see how slow it is. A few things that can help: if you're on vista+ turn off aero display manager (esp. If you have dual monitors, this can help).
Disabling or enabling 'hardware acceleration' for the desktop might help, too. Try switching from 32 to 16 bit. It's a tidge faster to capture (90fps compared to 80fps on my box) It captures much more quickly if aero is turned off (as in with aero, capturing a 650x976 window takes 50ms, without aero, 3ms). The rest of a single screenshot capture takes about 7ms (sum 10ms without aero), so you can see the relative cost it adds ! If you have dual core, then theoretically capturing with aero on will just cause the capture thread to probably eat 'an entire core' if you are trying to capture at 20 fps or higher.
So it may be worth it, if you have the extra cpu, to not care. Note that if your output is, say, going to be 10 fps 'used' in the end. Ex: ffmpeg -f dshow -i video=video-capture-recorder yo.mp4 -r 10 # output file is only 10 fps Then to save cpu, the 'good' directshow applications have their own 'source fps' parameter, that they pass on to this filter. Ex: vlc.exe dshow://.:dshow-fps=1.5 vlc then passes this in to SetFormat after negotiation, and the device accepts it. Some 'bad' directshow applications don't pass this in. So there may be a case where it is wasting cpu somehow, by capturing too many or the like. So for those programs, you'll want to set the forcemaxfps parameter, which will limit its capture frequency.
It may be the only way to pull in some rogue applications (ffmpeg ). Setting forcemaxfps to greater than 30 also allows you to get fps greater than 30. It 'enables' them, by giving it a higher max default. I didn't think people would normally care/want them so there you have. Other feedback/problems/questions ping me [email protected] or mailing list: Redistribution You can use this/redistribute it with your own software if you wish by just redistributing the DLL (PushDesktop.ax) alongside with your app (see installerjustdevice.iss). You'd have to register it manually (regsvr32 PushDesktop.ax, may need administrator rights) as part of your install. Also note that end users also need the MSVC 2010 redistributable previously installed (or you have to make it available in the same dir as your exe) for the dll to work/install, in case end users don't have it installed, in that case).
Or you may be able to recompile it to work around that, etc. Code/Future work/Attributions The code is gently lifted from ('inspired by'). Microsoft SDKs Windows v7.1 Samples multimedia directshow filters pushsource as well as some other dshow demos around. So you'll probably want to install the Windows SDK before messing around with the source code. I can add features upon reasonable demand. Basically you want a feature, ping me, you got it. To build it locally, install VS Express 2010, install Microsoft SDK, open up your equivalent of Program Files Microsoft SDKs Windows v7.1 Samples multimedia directshow baseclasses baseclasses.sln build it (debug) now add to your local build (project properties, from the sourcecode pushdesktop.sln) adjust the VC Directories (Include/Library) to point to your baseclasses.
Attributions the included speed test utility was originally from (bitblt is quite hardware dependent, or so I'm told). FFMpeg also included, see their site for licensing details/source: ffmpeg.org - Post added 12-10-11 at 04:57 PM - I am trying to record a part of desktop now.
Code: This is an audio capture device allowing you to capture all the 'wave out sound' that is playing on your speakers (i.e. Record what you hear) for Windows 7/Vista. Windows XP users please read the 'history' section for something else you can try in its place. NB THAT IT IS USED WITHIN THE MORE FULL FEATURED Installation To use, download+install here: then use it via its included 'record for x seconds' utility, or via any other program that can take directshow devices as an input.
If you want other options for its use, like broadcasting, or saving from it or any specific audio device input (ex: waveout with Windows XP) then download this utility: which has has more options and a different/better UI for broadcast/recording. NB that you may need need to install the MSVC 2010 runtime distro first, if it's not already installed on your machine (typically, it already is).
Usage Example: VLC media player: media menu - open capture device - select capture audio device 'virtual-audio-capturer' Example: ffmpeg (to save audio to file yo.mp3 from what is currently playing, requires 32 bit ffmpeg, 64 bit DLL available upon demand): $ ffmpeg -f dshow -i audio='virtual-audio-capturer' yo.mp3 (also see if you want to stream your desktop with audio as well or capture it or the like) NB that you'll need java JRE installed to use the bundled utility apps. History/XP users: Basically, with windows XP, you can typically already 'record what you hear' Run sndvol32 (Start menu - Accessories - Volume/Audio), choose options menu - properties - recording radio button, click ok, now click the 'select' checkbox underneath 'Wave Out Mix' Now with for example VLC choose 'Open Capture Device' - Audio Device Name - select 'your soundcard's name' (other programs just select your soundcard's name).
With Windows Vista/7, for some reason many sound card drivers do not include this as an option. Some do though. You can check if yours already does by following instructions here: You may want to download and install new audio drivers first before looking for it, sometimes that helps. If you're in Vista/Windows 7 and see a 'Wave Out Mix' following the above instructions then you're good to go: enable it, and you can use it (you thus don't need virtual-audio-capture-grabber-device at all). If you don't see it then you're in luck this, device is for you. Windows Vista/7 offer a new interface called a 'loopback' adapter that captures the outgoing audio just as it is sent to your speakers 1.
This little utility captures the loopback audio and offers it to you as an input device that you can then record (it's captured as a directshow audio capture device, if that means anything to you). VLC can use this to record, for example. There are some example apps included with this package. Basically I programmed this as an open source (free) competitor to virtual audio cable. Ping me if you want me to convert it into a 'real' kernel level audio device so that any program can use it, not just directshow compatible ones. Ping me if you want an easier 'start/stop' recorder, too.
Another option is 'If your sound card doesn't have the option to record what you hear, use a cable (with 3.5mm headphone jacks on both ends) to connect the line out of your sound card to the line in (using a splitter if you need to be able to hear what you're doing, and disabling mic boost if you use a microphone input).' But that's hardware and this is a software answer:) Troubleshooting/feedback If you use it in VLC you'll need a directshow cache of at least 40ms, for whatever reason. Also note that it's tuned set to work best for recording 'what you hear' if this doesn't work for you then ping me I maybe could add a more 'realtime' option or something. Basically any feedback welcome, if it doesn't work. Also note that if you turn down your system volume within windows, it will still continue recording or playing, as apparently it captures it at 'normal volume' regardless of how high your speaker output is.
Any feedback welcome, including feature requests like 'support more audio channels than 2'. If you want a smaller download you can just download the file sourcecode Release audiosniffer.ax then run regsvr32 audiosniffer.ax as an admin user. [email protected] or mailing list attribution Some source code originally from the windows SDK samples, some taken from 1 So you'll probably need to install the Windows SDK before playing around with the source code, legally. Also you may find this project, a directshow screen capture device, similarly useful: Enjoy!
1 In my case of XP. Quote: Configuration By default, it captures the 'full screen' of the main desktop monitor (all windows, overlapping, there).

If any value registry value is set to 0, that means 'not set' so it uses the default for that value. I did bother software developer 'rogerdpack' for that. Now this thread is solved.
