I when using form to upload files sizes (avchd,mp4,mkv,mpeg,mpg,mpe,avi,mov,flv) up to 12GB. When conducting a test with file size of 400mb upload freezes around 30 to 40%.
Files with size of few MB can be uploaded without any problems.
Ok, I have managed to solve this by setting max_input_time = -1 in my php.ini file.
However, now additional problem came up. I am getting error “This field is required” although the file is fully uploaded. Screen shot is in attachment!
