Webcam streaming from Mac using FFmpeg

Question

I want to stream my webcam from Mac using FFmpeg.

First I checked the supported devices using ffmpeg -f avfoundation -list_devices true -i \"\"

Answer 1

I experienced the same problem trying to stream a Logitech C920 webcam where streaming of the built in FaceTime camera works fine.

I found that reducing the frame rate stopped the error message you reported from being displayed. Here is the command I used to get my webcam working (where the same command with a frame rate of 30 did not work).

ffmpeg -f avfoundation -framerate 10 -pixel_format yuyv422 -i "0" out.avi

From the video formats your webcam supports it looks like the following command could work. Though as I do not have the same webcam this may not resolve your issue.

ffmpeg -f avfoundation -framerate 6 -i "0" -target pal-vcd test.mpg

I hope this helps you find a solution.

Answer 2

'-framerate' is needed

you can have a try

ffmpeg -f avfoundation -framerate 30 -i "0" -target pal-vcd ./test.mpg
