vapoursynth VS ffmpeg-python

Since ffmpeg CLI still makes me pull ny hair out, I am going to plug vapoursynth:

https://www.vapoursynth.com/

Its Pythonic video filters... But also so much more: https://vsdb.top/

And Staxrip, which makes such good use of ffmpeg, vapoursynth, and dozens of other encoders and tools that I reboot from linux to Windows just to use it: https://github.com/staxrip/staxrip

git clone https://github.com/vapoursynth/vapoursynth cd vapoursynth ./configure make sudo make install

Are you aware of Vapoursynth? https://www.vapoursynth.com/

I have a few options here to process the individual frames for example using ImageData, which exposes the data as an array of pixels, so you could easily 'borrow' some VapourSynth filters for this:

Does the name AviSynth mean anything to you? If so and you want a similar Linux native tool "inspired" by AviSynth, to quote the website, check out http://www.vapoursynth.com/ Just bear in mind that the scripting language is different.

I'm a total newbie to CUDA. I'm trying to implement NVOF in VapourSynth video processing framework. I got the NVOF context initialized. Next step is the buffers!

Download vapoursynth r57 portable from https://github.com/vapoursynth/vapoursynth/releases it's a 7z file so you should have 7-zip installed

Download and compile vapoursynth 1) Go to vapoursynth’s gihub (https://github.com/vapoursynth/vapoursynth/releases) download/wget the tar.gz 2) extract it with tar -xf 3) cd into the folder 4) sudo ./autogen.sh 5) sudo ./configure 6) sudo make install

Even given an option it can be difficult to find the corresponding documentation, if only because of the many different submodules and encoders and decoders and filters that have o-so-slightly different options. That said, I've just switched from pydub to ffmpeg-python (due to memory issues of the former[1]) and judging from the Jupiter notebook[2] it seems a much more intuitive method of constructing ffmpeg pipelines.

You might want to look into ffmpeg-python as well

This bug on github sounds like the same issue you have

take a look at https://github.com/kkroening/ffmpeg-python

The ffmpeg-python python package still makes use of the “future” python package (search for “past” in the code base). These should be removed and updated as necessary.

I've had a look through these examples, but I can't get the numpy conversion to work (I get broken pipe errors, but if any of you can get it working this solution would be ideal)

Your going to be wanting to enumerate all the files in a folder, shuffle them, and then use a library for splicing them together. A quick google search brought me to moviePy, which seems pretty solid. ffmpeg is the industry standard for programmatically working with video, but it's...complicated to say the least. Looks like there are some good python bindings for it, but it may be overkill for this project. I'm sure there are others out there too.

I've been using ffmpeg-python recently, and it will do a lot of the crazy complex transforms for you, and you can write sane python code vs. trying to deal with the crazy default ffmpeg syntax.

ffmpeg is the traditional Swiss Army knife for video stuff. there's a Python library out there. might not be appropriate in an embedded environment though, it's a bit of a beast.
