broken ffmpeg default settings detected

Question

I am getting broken ffmpeg error while VideoWrite using X264 Fourcc codec.I have install all the dependencies.How can I rectify this problem.The sample code that I have been using is as follows.

VideoWriter oVideoWriter ("path.mp4", CV_FOURCC('X','2','6','4'), 15, frameSize, false);

Operating system : Ubuntu 14.04 64-bit

Console Error:

Suggest me any solution for this.

What is the actual `ffmpeg` command (if using the cli tools and not the API)? What is the actual, complete `ffmpeg` console/log output? — llogan, Sep 03 '14 at 16:45
@LordNeckbeard I have updated my question with console log,Please look into this — Ramakrishna, Sep 04 '14 at 06:26
Please show the **complete** console output and the command too if possible. — llogan, Sep 04 '14 at 16:33
ffmpeg -i input_file -acodec libmp3lame -vcodec libx264 -y output.mp4 i am using this command , getting same error — Satishakumar Awati, Jan 29 '15 at 15:15
Are you insisting on h264? You could try using some other codec, such as MJPG for example. — mirosval, Apr 23 '15 at 11:10
Is the video playable? If your settings are wrong in OpenCV, it will create an ill-formatted video. — Oliver Tale-Yazdi, Dec 18 '21 at 14:59

for the error:

[libx264 @ 0x8d6220] broken ffmpeg default settings detected
[libx264 @ 0x8d6220] use an encoding preset (e.g. -vpre medium)
[libx264 @ 0x8d6220] preset usage: -vpre <speed> -vpre <profile>
[libx264 @ 0x8d6220] speed presets are listed in x264 --help
[libx264 @ 0x8d6220] profile is optional; x264 defaults to high

you may need the command -vpre perset (e.g. -vpre fast). maybe you libx264 is too old. I meet the same error while using a ffmpeg built in 2014.

Since libx264 is called indirectly, there is no way to give additional ffmpeg switches on any command line. — micha137, Apr 09 '18 at 09:06

I don't remember if you need to re build opencv with open h264 support, but for sure, standart opencv doesn't provide h264 codec. Here is a hint:

The question is about OpenCv on Linux. – micha137 Apr 09 '18 at 09:05

please install libx264-dev and try compiling openvc3.0 with that. follow this link
