• Write, with ffmpeg, every 30 seconds wav file from ip stream to file.temp and change the name to timestamp.wav after

  18 juillet 2018, par Eliya

  I’m using ffmpeg to record IP stream and write every 30 seconds to wav file.

  Here is my bash script code :

  #!/bin/bash
  
  function start_ffmpeg_stream ()
  
  {
  
      address=$1 #This is IP stream address
  
      ffmpeg_option=$2 # "?overrun_nonfatal=1&fifo_size=250000"
  
      folder_name=$3 #folderName
  
      channel_number=$4 #i
  
      #local pid      
  
      ffmpeg  -loglevel 8 -thread_queue_size 1500 -i "$address$ffmpeg_option" -c copy\
  
          -vn -f segment -segment_time 30 -ar 8000 -acodec pcm_s32le -ac 1 -strftime 1 /"$folder_name"/"X$channel_number""_""%s.wav"&     
  
      pid=$!
  
      echo "$Start ffmpeg, pid is - $pid" 
  
      __="$pid"
  
  }
  
  ffmpegOptions="?overrun_nonfatal=1&fifo_size=250000"
  
  folderName="/wav_files"
  
  start_ffmpeg_stream "udp://224.10.0.1"  "$ffmpegOptions" "$folderName" "1"

  Now the wav file name is like "X000001_unix_time_stamp.wav".

  I want to write the file name in writeing time something like "X000001_unix_time_stamp.temp"

  And when the 30 seconds done and the FFmpeg finish to write this 30 seconds, I want that FFmpeg changes the name to "X000001_unix_time_stamp.wav"

  And keep writing next 30 seconds.

  The only change that i want is, when FFmpeg writing it write in temp name and after FFmpeg finish to write it change the name.

  It’s seem to case when i donloaded a file so until the donload not finish the file has a temp name and when it done the name change to const name.

• ffmpeg batch process issue mac

  22 octobre 2023, par e e

  I'm using ffmpeg to batch process all files(with names containing spaces) in a directory. The script is like :

  


  echo my converter
read -p "Enter give folder: " folder
echo '//////////////////////START CONVERTING FROM FOLDER///////////////////////'

find $folder -type f -name "*[[:space:]]*" | while read file; do
    release="${file%%.*}"'_t.mp4';
    echo "$file";
    ffmpeg -i "$file" -c copy "$release" -loglevel error -stats
    echo $release;
done


  


  the script searches all the files in the address and ffmpeg one by one. However the first file will always fail due to some unknown issues :

  


  [mpegts @ 0x7fb8e9904a40] Continuity check failed for pid 17 expected 2 got 3
[mpegts @ 0x7fb8e9904a40] Continuity check failed for pid 0 expected 0 got 2
[mpegts @ 0x7fb8e9904a40] Continuity check failed for pid 4096 expected 0 got 2
[mpegts @ 0x7fb8e9904a40] Continuity check failed for pid 256 expected 2 got 7
[mpegts @ 0x7fb8e9904a40] Packet corrupt (stream = 0, dts = 203523000).
/Users/xy/Downloads/aaa/aa vv.ts: corrupt input packet in stream 0
[NULL @ 0x7fb8e9905a40] Decoding VUI



  


  If there is only one file, the process works fine.
If comment out the ffmpeg command, it echoes as expected :

  


  /Users/xy/Downloads/aaa/aa vv_t.mp4
/Users/xy/Downloads/aaa/aa vv_t_t.mp4
/Users/xy/Downloads/aaa/aa vv.ts
/Users/xy/Downloads/aaa/aa vv_t.mp4
/Users/xy/Downloads/aaa/cc ee.ts
/Users/xy/Downloads/aaa/cc ee_t.mp4


  


  it first find the target files and then converts into another with different file names.
Any suggestions, thank you !!
