Using NReco.VideoConverter commercially [closed]
1er octobre 2020, par BillyDayHi I am looking at using NReco.VideoConverter commercially for a product were looking at building, it will be used to generate videos but I'm a bit unsure on the licensing terms.


If we have an NReco enterprise license according to the terms we can use it. However when you run NReco.VideoConverter for the first time it generates FFMpeg.exe.


The terms of FFMpeg.exe is a little confusing and if NReco are not following the "License Compliance Checklist" it would fall under GNU General Public License (GPL) version 2 which can not be distributed commercially does anyone know if NReco is ok to use commercially or any guidance would be much apricated


Thanks all.

How to embed an MP4 inside a PDF ?
19 août 2020, par malatI am a happy user of img2pdf. This tool does the minimal amount of work to put a series of JPEG 2000/JPEG/PNG images into a PDF "enveloppe". However I am now faced with a new challenge : embed a MP4 file into a PDF "enveloppe".


I see that commercial tool can do it, as seen at :




Here is one such sample PDF file (no Flash required on windows in this sample) :

** https://gitlab.com/agrahn/media9/uploads/90fddd777e0ec514c39c924cd8d3b688/video_test.pdf




It seems to have been introduced in ISO 32000-1 (PDF 1.7 Extension Level 5)


I am looking for a solution which will use the Rich Media annotation inside the PDF stream.


There are dozen of duplicated questions on superuser/stackoverflow, which all pretty much refer to imagemagick/convert command line tool. But in my case,
convertexpand the images into a multi-page PDF (which is not my desired behavior) :

Getting error "DLL load failed while importing rect : %1 is not a valid Win32 application" while importing package
17 août 2020, par Sagar DonadkarI am using cython package to call Cpp API and in my cpp code i am using ffmpeg library and able to build my code successfully using bellow command


python setup.py build_ext --inplace --compiler=msvc


but when i try to import generated pyd file then i get error
