OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error

28 septembre 2016, par user2262504

I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.

It seems that OpenCV invoke ffmpeg API using default parameters and ffmpeg invoke x264 using its default parameters. Then these setting is broken for libx264. Thus the "Could not open codec ’libx264’" error.

Anyone has ideas to solve this problem ?

More specifically :

anyone knows where and how OpenCV invoke ffmpeg API ?
how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV ?
will changes of default in ffmpeg be carried to libx264 ?

Errors :

1. Uising CV_FOURCC('H', '2', '6', '4')

[libx264 @ 0x255de40] broken ffmpeg default settings detected

[libx264 @ 0x255de40] use an encoding preset (e.g. -vpre medium)

[libx264 @ 0x255de40] preset usage: -vpre <speed> -vpre <profile>

[libx264 @ 0x255de40] speed presets are listed in x264 --help

[libx264 @ 0x255de40] profile is optional; x264 defaults to high

Could not open codec 'libx264': Unspecified error



2. Using FOURCC = -1 to invoke user customized codec

backend doesn't support this codec acutally.) in CvVideoWriter_GStreamer::open,

The problem is that ffmpeg exits randomly after 5 to 20 minutes. The RTSP is a live stream so stopping every 5 minute is really not acceptable. In the ffmpeg log I can’t see any noticeable error except "No more output streams to write to, finishing." near the end. Can someone shed some light upon this ? How can I make ffmpeg run without stopping ? Thanks

OpenCV VideoWriter using ffmpeg with "Could not open codec 'libx264'" Error

19 avril, par user2262504

I am new to OpenCV, and I want write Mat images into video using VideoWriter on Ubuntu 12.04. But when constructing VideoWriter, errors came out.

Anyone has ideas to solve this problem ?

More specifically :

anyone knows where and how OpenCV invoke ffmpeg API ?

how to change ffmpeg default settings using code, hopefull, can be easily embeded into OpenCV ?

will changes of default in ffmpeg be carried to libx264 ?

FFMPEG

ffmpeg is enable to support OpenCV and libx264 is enabled when compiling ffmpeg.
By using ffmpeg command line, libx264 is running normally.
