• ffmpeg how to crop and scale at the same time ?

  13 décembre 2018, par Mitchell Faas

  I’m trying to convert a video with black bars, to one without and if the source is 4k, I want the video to be converted to 1080p

  Now to do this, I’m using the following command :*

  ffmpeg -i input ... -filter:v "crop=..." -filter:V "scale=1920:-1" ouput

  But running this, I found that the end product still has said black bars and is 1920x1080 as opposed to the 1920x800 I’d expect.

  What gives, why does this not work ?

• ffmpeg non-continuous live streaming

  2 août 2022, par xrfang

  I have an IP camera which is normally power off, and is triggered by Infra-Red signal. I plan to use ffmpeg to pull RTSP stream from it, and convert to HLS video segments.

  


  My question is, can ffmpeg work continuously and output blank MPEGTS chunks while it is not able to connect to the camera, i.e. works 7x24, waiting for video data, instead of crash/exit if it cannot connect to the camera.
