I have found that if I want to decode an image, I always get an empty Mat. Then I have found that the picture.jpg is in fact a gif. Is there a way to open a gif that is just an image?
Just like a parenthesis: why it is a gif if the link is ending with .gif, resulting in a jfif header?
the answer is YES if you compile OpenCV with GDAL support.
In the case you set WITH_GDAL flag to true in CMake and IMREAD_LOAD_GDAL to load the image, then GDAL driver will be used in order to decode the image by supporting the following formats: Raster,Vector.
image = imread( inputImage, IMREAD_LOAD_GDAL);
another way ( simplier ) use VideoCapture to open gif image
no, there's no gif decompression built in. (probably still a patent issue)
