• I need the script to work on all dav files

  4 décembre 2019, par audicom

  Script should run in recursive mode, find DAV files and start DAV to JPG conversions using FFMPEG. The script is working, identifying files in folders and starting conversions when DAV files exist, but is ignoring some DAV files.
  When I put these DAV files back in the folder it converts correctly.
  What could be wrong ?
  I thought it might be the speed of the process, since the files are being generated in the folder, the script must wait for the file to be closed and complete to act. I tried to delay the conversion process by 15 seconds using a PING, but it still skips some files.

  cd E:\VM01\1002
  
  MD "E:\COLETA SNAPSHOT\SNAPSHOT 1002"
  
  MD  "E:\COLETA SNAPSHOT\PROCESSED 1002" 
  
  
  
  :LOOP01  
  
  PING 1.1.1.1 -n 10 -w 6000 >NUL     
  
  For /R %%G in (*.Dav) do IF NOT EXIST "%%G" GOTO SKIP01
  
  
  
  :LOOP02
  
  PING 1.1.1.1 -n 10 -w 6000 >NUL    
  
  For /R %%G in (*.Dav) do IF EXIST "%%G" GOTO SKIP02
  
  REM ALL THIS WILL BE DONE IF THE DAV FILE EXISTS
  
  :
  
  :
  
  :SKIP01
  
  REM 6 SECONDS OF DELAY ...
  
  PING 1.1.1.1 -n 10 -w 6000 >NUL
  
  GOTO LOOP01
  
  :
  
  :
  
  :SKIP02
  
  REM START CONVERSION
  
  PING 1.1.1.1  -n 10 -w 15000 >NUL
  
  For /R %%G in (*.Dav) do IF EXIST "%%G" ffmpeg -i "%%G" -r 0.2 -bt 20M -s 480x300 "%%~nG"%%06d.jpg
  
  for /r %%G in (*.Dav) do Move "%%G" "E:\COLETA SNAPSHOT\PROCESSED 1002"
  
  Move "*.jpg" "E:\COLETA SNAPSHOT\SNAPSHOT 1002" 
  
  PING 1.1.1.1  -n 10 -w 3000 >NUL

• ffmpeg -stream_loop doesnt work on hls file

  7 décembre 2022, par Enrique Corpus

  Can someone pls help me figure out my problem with ffmpeg. When I try to add -stream_loop option on the command, I got an error

  


  [AVIOContext @ 0x7f8c42705080] Statistics: 362088 bytes read, 0 seeks296.7kbits/s speed=1.01x Seek to start failed. playlist_main2.m3u8: Operation not permitted

  


  And here is my ffmpeg command
ffmpeg -stream_loop -1 -i playlist_main2.m3u8 -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 file.mp4

  


  Im thinking the problem might be on the .ts file, since I dont encounter this error when testing differet hls files, but I want to have a proof that the source is the proble. Pls help me. Attached is the m3u8 file and the .ts file.
HLS FILE

  


  Tried different hls file and the command works. Now im suspecting the problem is on the video (.ts) file itself but i cant prove it.
