Could not find encoder for codec id 27: Encoder not found

[acodercat]

OpenCV: FFMPEG: tag 0x34363258/'X264' is not supported with codec id 27 and format 'mp4 / MP4 (MPEG-4 Part 14)'
OpenCV: FFMPEG: fallback to use tag 0x31637661/'avc1'
Could not find encoder for codec id 27: Encoder not found

H264 encoding is not supported because it falls under GPL license. See: #100

You must build OpenCV yourself and link it with system FFmpeg.

About licensing:

If I ship GPL'ed components with opencv-python I would have to re-license the whole package under GPL license and any package using opencv-python, respectively, would have to be licensed under GPL. This would also mean that this package or any package which uses opencv-python could not be used for commercial purposes / proprietary applications unless you are willing to publish your software source code.

This helps. Thank you.

But how can I do?

If you are using conda, uninstalling OpenCV through pip and instead using conda install -c conda-forge opencv worked for me! I can run cv2.VideoWriter('out.mp4', cv2.VideoWriter_fourcc(*'avc1'), FPS, (WIDTH, HEIGHT)) without issues.

Thank you so much you saved my day! This IS the SOLUTION!
