• Running list of cmd.exe commands from maya in Python

  17 décembre 2015, par user3541686

  I am writing a maya python script to batch render a scene into jpgs then use ffmpeg to turn them into a mov. Currently the script saves a string of commands as a bat file which works fine but I’d prefer to just run cmd.exe from maya and execute the list of commands without creating that bat first.

  I’ve been reading about "subprocess.popen()" but I can’t figure out how to get it to iterate through each line, run that command, then move onto the next one when done ie :

  1) Run maya render.exe & save scene as jpegs

  2) ffmpeg jpgs to mov

  I’ve shortened the directories but its essentially this :

  `C:\PROGRA~1\Autodesk\Maya2015\bin\Render.exe -r hw2 -s 100 -e 200 -of jpg -fnc 7 -x 1920 -y 1080 -rd 
  
  "C:\RENDER" 
  
  "C:\SCENE.ma" ffmpeg -y -r 25 -start_number 0100 -i C:\SCENE_%%04d.jpg C:\SCENE.mov

  How would I be able to do this ?

  Thanks !

• FPV-Camera Input in Black and White / losses Color on conversion with FFMPEG [closed]

  22 décembre 2023, par LyffLyff

  so we're working on our end-of-school project and it's an FPV-Drone with an Analogue Camera on it. Plan is to send the video feed to a Raspberry Pi running an RTMP-Server from where a Phone-Application can view the live Video of the camera.

  


  To convert this analogue Data from the camera we use a USB2.0 Grabber (this one).

  


  To create the RTMP Stream from the converted USB-Input we use FFMPEG with the following command :

  


  


  fmpeg -f v4l2 -input_format yuyv422 -i /dev/video0 -c:v libx264 -crf 20 -preset ultrafast -b:v 2000k -fflags nobuffer -rtmp_live live -f flv rtmp ://192.168.8.107:554/live/stream

  


  


  It works fine, but the main problems at the moment are :

  


  

  • the video is in Black and White
B&W Image Stream

  


  • the stream has a delay of 10-20s depending on the network

  


  


  When I'm using the official Software provided by the Reseller I had the same problem, but as soon as it set PAL/BDGHI in the Settings the colour was shown correctly :

  


  Settings and Color Image in official software

  


  the video is in Black and White

  


  Does anyone know what settings there are to correctly decode the feed from the Camera and send the video with the colour over RTMP ? I don't know if this is the right place to ask this question, but I'm running out of ideas and every single decoder I have tried apart from the ones I'm currently using does not work.

  


  Any help is greatly appreciated :)
