Error building MLT framework on Windows

问题 I've been following the official building guide provided here. I need MLT to create a video player and I opted to only install the first 4 libraries, as stated on the guide (FFmpeg, SDL, dlfcn-win32, and libXML). I'm also using QT as my main framework for my application. I'm a bit confused as far as this guide goes because I find the instructions for where the libraries should go a bit confusing. This is my current folder structure: $HOME = C:\MinGW\msys\1.0\home\TKB (TKB is my user) $HOME

Understanding MLT melt mixer luma mix (fade) duration?

问题 Related to Understanding/controlling MLT melt slideshow?, I am trying to understand how does melt's luma mixer work, especially in context of short (small frame number) durations. For instance, if I use something like this specification tmppics/pic_01.jpg length=6 -mix 2 -mixer luma I would have expected 2 frames of fade of pic_01, then 2 frames full pic_01, then 2 frames of fade again - however, I've both experienced results that are like this, and those that are not. To clarify this, I've

MLT (Media Lovin' Toolkit) Photo Slide Video

问题 I'm using MLT from the command line on a series of images. When I run: melt 0.jpg 1.jpg 2.jpg 3.jpg It generates a video where each photo occupies one frame (4 frame long video). I want each photo to occupy 100 frames. I've tried every combination of properties I can think of, such as: melt 0.jpg out=100 1.jpg in=100 out=200 2.jpg in=200 out=300 etc. But the results are not as intended. I've also tried organizing into tracks, and melting from an XML file. At best, I've been able to get the

问题 Consider the following bash script (on Ubuntu 18.04, melt 6.6.0), which uses melt to make a slideshow and play it locally in a window (SDL consumer), mostly copied from https://mltframework.org/blog/making_nice_slideshows/ ( edit: I'm aware that's its possible to specify files individually as in https://superuser.com/questions/833232/create-video-with-5-images-with-fadein-out-effect-in-ffmpeg/834035#834035 - but that approach seems to scale images during transition, and takes quite a while to
