Hello, I am currently developing a program for the distribution of video (or others) on giant LED screens. Some video exceeds 4096px and I can't open them via the "cv::cudacodec::createVideoReader" function

Do you have an idea to solve my problem? I thank you in advance

ps : Here is the error :

Assertion failed (videoFormat.width >= decodeCaps.nMinWidth && videoFormat.height >= decodeCaps.nMinHeight && videoFormat.width <= decodeCaps.nMaxWidth && videoFormat.height <= decodeCaps.nMaxHeight) in cv::cudacodec::detail::VideoDecoder::create

I guess there are 2 alternatives: 1) modifying the software and hoping it works... 2) as only some videos are too large, the resolution may not be a critical requurement, so a workaround would be pre-rescaling them with FFMPEG
