Video codec for H264 with opencv

Question

I am trying to create a movie using opencv and I need that output file be in H264 format.

I used the following fourcc in opencv, but I am getting error that suitable codec is not installed.

fourcc=CV_FOURCC('H','2','6','4') ;

When I run my application I get the following error message:

Could not find encoder for codec id 28: Encoder not found

What do I need to be able to use this codec in OpenCV?

What operating system are you using? – sietschie Jun 10 '13 at 14:16 — sietschie, Jun 10 '13 at 14:16
You can also try CV_FOURCC('A', 'V', 'C', '1') – Paul Gregoire Jan 29 '15 at 17:13 — Paul Gregoire, Jan 29 '15 at 17:13

H264 is not a codec, but rather a standard, while for example x264 is an encoder that implements the H264 standard (CV_FOURCC('X','2','6','4') ;).

OpenCV can write videos using FFMPEG or VFW. You need to compile FFPMEG with x264-support (instructions can be found on FFMPEG's website)

do you know the fourcc or id for the VFW x264 codec? If I use `fourcc=CV_FOURCC('X','2','6','4') ;` I get a warning in the terminal and a vfw log window which I would like to omit. But the video is successfully recorded... so I just want to remove the warning messages and windows, I guess I would achieve this by providing the right id or fourcc code... – Micka Oct 14 '16 at 09:16
