• Two character glob pattern

  18 octobre 2022, par eSlavko

  I have camera capturing image every 10 seconds and store in folder with image name as timestamp like
/2022-05-10_19:11:50.jpg
Each week is stored in separate folder.
Now I want to make video from that images using ffmpeg.
It works with images declared as -pattern_type glob -i "*.jpg" Now I want to make video from images captured only in daytime. For example from images /2022-05-10_XX:11:50.jpg where XX is in range from 05, 06, 07 .. 20, 21. I try with glob patterns but seems that it can work only over single digit.

  


• Download M3U8 That Is Playable

  15 octobre 2022, par Devin Dixon

  I am trying to download a livestream from this traffic camera source : https://vss1live.dot.ga.gov/lo/alph-cam-002.stream/playlist.m3u8

  


  The ffmpeg I am using is :

  


  ffmpeg -i https://vss1live.dot.ga.gov/lo/alph-cam-002.stream/playlist.m3u8 -preset slow -codec:a libfdk_aac -b:a 128k -codec:v libx264 -pix_fmt yuv420p -b:v 4500k -minrate 4500k -maxrate 9000k -bufsize 9000k -vf scale=-1:720 test.mp4


  


  And here are the logs when I quit the recording :

  Except the video doesn't seem to be playable by VLC or Quicktime. Given that the stream can end at any moment thus ending the file, how do I make the file actually playable ?
