• How to specify video resolution when saving stream with ffmpeg

  30 septembre 2022, par Vitaly579

  Now, to save the video stream to a file, I use the command :

  


  ffmpeg -rtsp_transport tcp -i 'rtsp ://ADMIN:PASS@192.168.100.53/cam/realmonitor ?channel=1&subtype=0&unicast=true&proto=Onvif' -t 5 -vcodec copy C :\Video\test.mp4

  


  and I receive a video file with a resolution of 2304 x 1296, which is redundant for me, I would like to receive a file with a resolution of 1280 × 720, is it possible to do this immediately by saving the stream ?

  


  I will be very grateful for your comments

• write_gif is automatically changing the resolution of the resultant gif as compared to the supplied video(mp4) file ? How to avoid that ?

  14 septembre 2022, par Mohammed Hussain

  Please see the code below and the result. How can we get the gif in the original dimensions. The moviepy documentation doesn't seem to say much.

  


  from moviepy.editor import *  import os  os.chdir(r'G:\')  clip = VideoFileClip("VID.mp4").subclip(6*60, 6.1*60) clip.write_gif("vidgif.gif",program = 'ffmpeg')
