Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

avutil : add ROI (Region Of Interest) data struct and bump version
10 janvier 2019, par Guo, Yejunavutil : add ROI (Region Of Interest) data struct and bump version
The encoders such as libx264 support different QPs offset for different MBs,
it makes possible for ROI-based encoding. It makes sense to add support
within ffmpeg to generate/accept ROI infos and pass into encoders.Typical usage : After AVFrame is decoded, a ffmpeg filter or user's code
generates ROI info for that frame, and the encoder finally does the
ROI-based encoding.The ROI info is maintained as side data of AVFrame.

and this 2 person can run code without any problem
but i have.

Error i got after run the code


= RESTART: D:\Bots\2vidpod.py
Traceback (most recent call last):
 File "D:\Bots\2vidpod.py", line 71, in <module>
 os.remove(os.path.join(output_folder, 'temp.mp4'))
FileNotFoundError: [WinError 2] Не удается найти указанный файл: 'D:\\bots\\ttvidads\\VID\\ZAGOTOVKI\\Videopod1\\temp.mp4'
</module>


so things i checked is
path is right
programs is installed FFMPEG and PYTHON all additional libraries downloaded
i pretty sure error caused by regular path and i wanna know if absolute path can do the thing
