Basic Webcam Recording Commands in FFmpeg

Using FFmpeg to record a webcam or another video input device requires specific commands. You can access the list by typing -h for help or man ffmpeg for the entire manual and hitting Enter.

That's the beauty of CLI tools; you can run these help-related commands anytime to see the available options. Another helpful FFmpeg command is ffmpeg -formats. It lists all supported file formats. The same goes for ffmpeg -codecs.

As you'll see in the manual, specifying such a flag modifies the operation. For instance, flags can tell FFmpeg which video input device to use and in which format to save the file.

FFmpeg has built-in Windows DirectShow (dshow) support for audio and video input devices. It's Microsoft's COM-based multimedia framework for streaming and playback. You'll use it in nearly all commands to capture and process media streams. Check the official FFmpeg's DirectShow input device documentation for more details.

Here's how to record a webcam with FFmpeg:

1. Run the following command in the CMD. You'll see a DirectShow video and audio device list, including your webcam. This example shows one integrated camera and a third-party recorder, but your results will differ. They may also contain your camera's default and alternative name.
   ffmpeg -list_devices true -f dshow -i dummy
2. Run this command to instruct FFmpeg to record a video from a webcam. However, use your webcam's default or alternative name and replace "mp4" with the desired output format.
   ffmpeg -f dshow -i video="Camera" out.mp4
3. Run this command to capture your microphone while recording the webcam. Again, use the correct device names and the wanted format.
   ffmpeg -f dshow -i video="Camera":audio="Microphone" out.mp4
4. You can wrap the video and audio device in a single quote (like in the screenshot below). It's more straightforward.
   ffmpeg -f dshow -i video="Integrated Camera":audio="Microphone name here" out.mp4
5. Type q in the Command Prompt to finish recording.

Advanced Webcam Recording Commands in FFmpeg

FFmpeg supports dozens of commands and various flags. For instance, you can instruct FFmpeg to record your camera at 60 frames per second and use a specific video codec.

Here are some advanced commands for recording your webcam with FFmpeg:

1. Run the following command (replace "Camera" with your webcam's name) to check your webcam's options. You'll see the supported codecs and minimum and maximum size and fps values.
   ffmpeg -f dshow -list_options true -i video="Camera"
2. Here's an example command to capture the webcam in a raw pixel format at 7.5 fps and output it as AVI. Again, use the correct camera name and the desired format.
   ffmpeg -f dshow -video_size 1280x720 -framerate 7.5 -pixel_format yuyv422 -i video="Camera" out.avi
3. This command tells the program to capture your camera using an MJPEG video codec and the minimum supported fps:
   ffmpeg -f dshow -video_size 1280x720 -framerate 15 -vcodec mjpeg -i video="Camera" out.avi.
4. Here's an example command with the -t flag to record a webcam and microphone for ten minutes:
   ffmpeg -f dshow -video_size 1280x720 -framerate 30 -t 00:10:00.00 -vcodec mjpeg -i video="Camera":audio="Microphone" out.avi.

As you can see, FFmpeg has straightforward commands; you can quickly remember them. Review the manual for more information and make test recordings to see FFmpeg in action.
