I have gotten the avc1 codec working for MP4 files, in order to use x264 or h264 I had to change the file extension to .mkv (If you know how to fix this let me know in the comments). opencv-python is already installed on this image, if you re-install opencv-python using pip, it will break. The following are code examples for showing how to use cv2.VideoWriter().They are from open source Python projects. These are the FOURCCs I know about that refer to compressed formats (the ones that you see displayed when you don't have the right codec installed to play a given AVI file). filename: Name of the output video file. FFMPEG backend with MP4 container natively uses other values as fourcc code: see ObjectType , so you may receive a warning message from OpenCV about fourcc …

fourcc = cv2.cv.CV_FOURCC(*'XVID') The above line is used for avi video.

List of codes can be obtained at Video Codecs by FOURCC page. Python OpenCV Writing To A Video – In this Python OpenCV article i want to show you how you can do Writing in To A Video so for this you can watch my previous post on How To Read Mp4 Videos In Python OpenCV.. so now let me first write the complete code for this article. fourcc: 4-character code of codec used to compress the frames.

Video Codecs by FOURCC. 编译安装后import cv2正常引入即可，代码就不放了，原文和网上都有，只是改个fourcc。 至此在Python中调用OpenCV录制H264编码的MP4视频已经可以实现，没有特殊需求的同学看到这里就可以了~撒花！ 使用vidgear库录制视频

MJPG is a safe choice.

In the same fashion, which codec do we use for mp4 videos in Ubuntu? ビデオが保存されていない時には、FourCCコードをいろいろ試してみよ。私のあるマシン(Linux, Anaconda Python 3.5.2)ではXVIDでは保存されず、MJPGなら保存できた。 I'm trying to record a video with the X264 codec and MP4 format. Hi, I asked this question last week about the video writer in OpenCV-3.0.0 with Python 2.7 not working properly, but didn't get any answers.

For example, VideoWriter::fourcc('P','I','M','1') is a MPEG-1 codec, VideoWriter::fourcc('M','J','P','G') is a motion-jpeg codec etc. I am not able to create video from image arrays, using the cv2.VideoWriter().

List of codes can be obtained at Video Codecs by FOURCC page. I am using Opencv-3.0.0 through Python 2.7.

I am surprised nobody else is facing similar problems. OpenCV: FFMPEG: tag 0x34363258/'X264' is not supported with codec id 28 and format 'mp4 / MP4 (MPEG-4 Part 14)' OpenCV: FFMPEG: fallback to use tag 0x00000021/'!???'

The resulting video recording works, and can be played with a videoplayer, however I receive following warning. OpenCVで作成した動画をサイトで表示する場合、ローカルで再生できていても、ブラウザ上では突然プレビューがでなり、ハマることがあります。原因の特定が難しい現象ですが、動画を作成する際にH.264形式でエンコードするとうまくいきました。 Sometimes, even when the specific codec is available, OpenCV may not be able to use it. You can vote up the examples you like or vote down the ones you don't like.

Note: Only a few of the FourCC codes listed above will work on your system based on the availability of the codecs on your system. For example, VideoWriter::fourcc('P','I','M','1') is a MPEG-1 codec, VideoWriter::fourcc('M','J','P','G') is a motion-jpeg codec etc.
