• What would be the correct way to use Exec or Transcode ffmpeg in SRS version of Windows 5.0.128

  29 janvier 2023, par diegosn79

  i was doing tests in different ways, and i can't use the Exec or Transcode option, i highlight that I have copied the ffmpeg.exe in the objs folder.
These are the codes I tried, and I attach the log errors.

  


  exec {

enabled on;

publish ./objs/ffmpeg.exe -rtbufsize 10M -i rtmp://10.1.9.240/live/encoder  -vf scale=1080:720 -c:v libx264 -profile:v high -level 4.2 -preset fast -b:v 1500k -c:a aac -ac 2 -b:a 96k -f flv -y rtmp://10.1.9.240:1935/live/encoderlow/;

}

• FFMPEG split mp3 and add metatag [closed]

  4 mai 2023, par Ghile

  I have a 2 hour mp3 that I automatically split with python3 and ffmpeg into many mp3 files. I would also like to add metadata to mp3 files, in order to have title, artist, year and album.

  


  In a csv file I have the cutting times and the name of the mp3 file, but I can't add meta data. The function I use is this :

  


  ffmpeg -loglevel panic -i 1.mp3 -ss 02:29:11 -to 02:34:43 -c copy -metadata 'title=My Title', 'artist=ME', 'date=2023' temp/myfile1.mp3


  


  Not work, It only works if I set the title only. Can you help me, please ?
Thank you,
