• RTMP Disconnects quickly when the stream is turned on and No index.m3u8 files are being generated in the assigned directory [closed]

  These are the logs, ffmpeg pushes the stream in a different folder when tried manually.

  


  

  • I tried changing the location of my file outside of oneDrive to avoid any permission conflicts.

  


  • Manually checked if FFmpeg is correct with this command : C:\ffmpeg\bin\ffmpeg.exe -i rtmp://localhost/live/test -c:v copy -c:a aac -f hls -hls_time 2 -hls_list_size 5 -hls_flags delete_segments output/index.m3u8

  


  • Downgraded NMS to a stable version.

  


  


• How to quote a file name with a single quote in ffmpeg movie= filter notation ? [closed]

  21 avril, par PieterV

  I am trying to run ffmpeg using a file that contains a single quote ' in the filename.

  


  I tried to follow the docs that say I should replace a ' with '\''.
  
And a ticket that says I should replace a ' with \\\\\'.

  


  I've tried both, and can't get get it working.

  


  E.g. docs format :

  


  ./ffprobe -loglevel error -read_intervals %00:30 -select_streams s:0 -f lavfi -i "movie='D\:\\Test\\Interlaced - Dragons'\'' Den - S14E02 - Episode 2.mkv'[out0+subcc]" -show_packets -print_format json

{
[Parsed_movie_0 @ 00000222a2f82200] Failed to avformat_open_input 'D:\Test\Interlaced - Dragons Den - S14E02 - Episode 2.mkv'

movie='D\:\\Test\\Interlaced - Dragons'\'' Den - S14E02 - Episode 2.mkv'[out0+subcc]: No such file or directory


  


  E.g. ticket format :

  


  ./ffprobe -loglevel error -read_intervals %00:30 -select_streams s:0 -f lavfi -i "movie='D\:\\Test\\Interlaced - Dragons\\\\\' Den - S14E02 - Episode 2.mkv'[out0+subcc]" -show_packets -print_format json

  This is on Win11 using FFmpeg7.
  
Any ideas ?

  


  [Update]
  
I found a doc on escape filtergraph strings, did not help, I tried 0 to 7 \.

  


  I also found and tried the ffescape utility, the output it produces just uses a single \' and does not work.

  


  > echo "D:\Test\Interlaced - Dragons' Den - S14E02 - Episode 2.mkv" | ./ffescape.exe
=> D:\\Test\\Interlaced - Dragons\' Den - S14E02 - Episode 2.mkv\

> ./ffprobe -loglevel error -read_intervals %00:30 -select_streams s:0 -f lavfi -i "movie='D:\\Test\\Interlaced - Dragons\' Den - S14E02 - Episode 2.mkv\'[out0+subcc]" -show_packets -print_format json

movie='D:\\Test\\Interlaced - Dragons\' Den - S14E02 - Episode 2.mkv\'[out0+subcc]: No such file or directory


  


  [Update]
  
I found docs for ffmpeg filter script where I can place commands in a file.

  


  I tried ./ffprobe -loglevel error -read_intervals %00:01 -select_streams s:0 -f lavfi -/i "d:\filtergraph.txt" -show_packets -print_format json, and it load the script.

  


  Works : movie=test.mkv[out0+subcc]\ if test.mkv is in ffprobe dir.
