FFMPEG x264 (fourcc=0x21) codec is not working with OpenCV
6 mars 2020, par dkacI'm trying to use mp4 format coding (fourcc=0x21) on OpenCV 3.2 without success. Probably I have a problem with my Ubuntu 18.04 setup but currently I'm running out of ideas how to fix it. First, I recompiled FFMPEG with x264 support. Than, recompiled OpenCV (with contrib and OPENCV_ENABLE_NONFREE=ON, WITH_FFMPEG=ON). It is still not working.



I cannot use fourcc different than 0x21. I mean.. I cannot use another codec.



Example :



>>> import cv2
>>> out = cv2.VideoWriter('output.mp4', 0x21, 20.0, (640,480))
OpenCV: FFMPEG: tag 0x00000021/'!???' is not found (format 'mp4 / (null)')'




However, this is working fine (other fourcc, codec) :



>>> out = cv2.VideoWriter('output.mp4',0x31637661 , 20.0, (640,480))




OpenCV compiled with FFMPEG support (version 3.2), cmake config :

configure : Avoid requiring c99wrap for working around msys path issues
14 novembre 2013, par Martin Storsjöconfigure : Avoid requiring c99wrap for working around msys path issues
Msys is unable to convert unix style absolute paths to windows style
paths when combined with certain multichar MSVC options such asFo<file>. We used to work around this issue by passing them as two
separate parameters separated by a space to c99wrap, which then mapped
them back to the actual parameter format that MSVC uses.The only paths that actually are an issue are absolute unix style
paths, and the only place such absolute paths are used with the output
arguments (-Fo, -Fe, -Fi, -out :) are for the temp files within configure.By setting TMPDIR to . for msvc/icl builds, we never need to use
absolute unix style paths for the file output, and we can use the
actual proper form of the file output parameters. This avoids requiring
the c99wrap wrapper for remapping the parameters for cases where the
c99 converter isn’t invoked at all (MSVC2013 and ICL).Signed-off-by : Martin Storsjö <martin@martin.st>
