  16 novembre 2019, par guardian presence

  Looking to use ffmpeg to pull video trsp stream over tcp pass the video feeds to opencv for object recognition and tracking passing the output to ardunio serial control systems like alarm systems drones ardunio controlled lawn mores.

  Lets say some one has a cctv system and a drone laying around if they connect to my cloud the system can pull the stream from the cctv cameras pull the stream from the drone if object moves in on camera zone the cloud can control the drone to move to that zone and take a closer look at a face if face detected send alert return drone to docking . if ptz camera opencv tracking zooming to face

  if ros can turn into a cloud service need to know about hosting and
  building front end user login and device login.

  i’m a cctv installer new to programming and want to setup cloud login for camera iot devises were users can control and monitoring of devices from a central cloud

• How would I make my clips cut by PySceneDetect .03 second longer ? (PySceneDetect)

  12 novembre 2019, par barry b. bensen

  I am cutting clips from a video apart using FFmpeg and PySceneDetect’s detect-content and split-video.
  It spits out the clips from the video in a folder.

  Everything is working, but the clips are ending .03 seconds too early (under a second, not exactly .03). I would either like to make them cut .03 seconds later or add .03 seconds onto the clip’s length to try to include what would have been cut. (whatever way to get that last bit of the clip where it belongs and not on the front of the next clip).

  The ending of the clip that is cut off is being added to the next clip in the folder (the scene that was cut next, from the video).

  I have played around with the sensitivity of the detect-content (what is used to tell if the scene in a video is a new scene or not) and this isn’t affecting the last bit that is cut off of the clips. I think I have to change something in one of these .py’s

  but have not been able to understand them.

  after no progress i gota ask for help

  The start has video (and sound) from the clip that was cut before it

• FFMPEG image to video with kenburns effect

  11 novembre 2019, par Buu

  I am new to FFMPEG and I kinda confused with their commands and options. So I googled some existing commands and found this :

  ffmpeg -y -loop 1 -i bgimage.png -ss 0 -t 5 -r 1 -loop 1 -i front.png -ss 0 -t 5 -filter_complex " [1:v] scale=w=1920:h=1080 [fg]; [0:v] scale=w=-2:h=3*1080 , crop=w=3*1920/1.2:h=3*1080/1.2:y=t*(in_h-out_h)/5, scale=w=1920:h=1080, setsar =1 [bg] ; [bg][fg]overlay=shortest=1[v] " -map "[v]" -c:v h264 -crf 18 -preset v eryfast pan_up.mp4

  The only problem is effects becomes sluggish.

  I am trying to convert image to video with kenburns effects. Can you guys help me out ? Calling ffmpeg masters here in SO. Your help will be greatly appreciated. Thank you so much !
