• FFMPEG on MACOSX is complaining "no matches found"

  15 juin 2022, par Byte Player

  I have a FFMPEG command line function that works perfectly on Windows but on Mac produces the following error :

  


  "no matches found [1:a]adelay=15000:all=1[aud2]"
  
"no matches found [2:a]adelay=5000:all=1[aud3]"

  


  Here is the command (less the full paths which just made it very hard to read). I've verified that the files exist at the paths specified by copying the file path from the command line and going into terminal, typing "open" then pasting in the copied path and pressing enter. In all cases they played.

  


  ffmpeg -loglevel warning -hide_banner -y -i "file1.mp3" -t 5 -i "file2.mp3" -i "file3.mp3" -i "file4.mp3" -ss 25 -t 15 -i "file5.mp3" -ss 15 -t 5 -i "file6.mp3" -filter_complex [1:a]adelay=15000:all=1[aud1];[2:a]adelay=5000:all=1[aud2];[4:a]adelay=25000:all=1[aud4];[5:a]adelay=5000:all=1[aud5];[aud1][aud2][aud4][aud5]amix=inputs=6:duration=longest:dropout_transition=0:normalize=0 "output.mp3"


  


  I know the immediate response (as it should be), is update your FFMPEG but I got the latest build (built on 2022-06-12) and here's what it reports...

• Stream PNG file to youtube with ffmpeg

  3 avril 2022, par codingmaster398

  What I'm trying to do :
I have a PNG file that is constantly getting written to. I want to pipe it (while it changes) to YouTube's RTMP server.

  


  What I've attempted :

  


  runCommand(
      'ffmpeg',
      `-threads:v 2 -threads:a 8 -filter_threads 2 -thread_queue_size 512 \
-loop 1 -re -i place.png \

    () => {},
    () => console.log('finished')
)

setInterval(()=>{
  image.write('./place.png') // Jimp },5000)

• av_interleaved_write_frame() : Cannot allocate memory, Error writing trailer of udp

  30 août 2022, par Technical_Union7716

  I'm transcoding from udp input to mpegts udp output. After several hours ffmpeg used all ram memory. I don't know where the problem is.
