Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Use FFMPEG driver in opencv
9 janvier 2021, par user3313834I have a camera on my linuxbox it is working well :


# $ ls -al /dev/video*
# crw-rw----+ 1 root video 81, 0 janv. 8 16:13 /dev/video0
# crw-rw----+ 1 root video 81, 1 janv. 8 16:13 /dev/video1
# $ groups
# adm cdrom sudo dip video plugdev lpadmin lxd sambashare docker libvirt



From python with cv2 it work well with the default driver
CAP_V4L2


>>> from pathlib import Path
>>> import cv2
>>> print(cv2.VideoCapture(0, apiPreference=cv2.cv2.CAP_V4L2).isOpened())
True
>>>



I would like to access it with the FFMPEG driver (no success) :


>>> print(cv2.VideoCapture(0, apiPreference=cv2.CAP_FFMPEG).isOpened())
False
>>>



From Python side the opencv look like to have the FFMPEG Driver :


>>> cv2.__version__
 '4.4.0'
 >>> info = cv2.getBuildInformation()
 >>> video, parallel = info.index('Video'), info.index('Parallel')
 >>> print(info[video:parallel])
 Video I/O:
 DC1394: NO
 FFMPEG: YES
 avcodec: YES (58.109.100)
 avformat: YES (58.61.100)
 avutil: YES (56.60.100)
 swscale: YES (5.8.100)
 avresample: NO
 GStreamer: NO
 v4l/v4l2: YES (linux/videodev2.h)
 >>>



From Linux side look ok too :
