  30 avril 2022, par Taqi Vaheed

  I use a .bat file to batch attach audio tracks to movies. Everything was good but in last days the ffmpeg stopped working correctly. When I restart the pc it work again but after some task the error come back. I tried to reinstall the windows but the problem does not solved.

  


  here is my ffmpeg code :

  


  for %%a in ("*.mp4*") do ffmpeg -y -i "%%a"^
 -itsoffset 0^
 -i %%~na.mp3 -i cover.jpg^
 -map 2 -map 0:v:0 -disposition:0 attached_pic^
 -map 1:a:0 -disposition:a:0 default^
 -map 0:a:0 -disposition:a:1 none -sn^
 -metadata title=""^
 -metadata:s:a:0 handler_name="Persian"^
 -metadata:s:a:1 handler_name="English"^
 -metadata:s:v:0 handler_name="English"^

• fftools/cmdutils : Add function to report error before exit

  fftools/cmdutils : Add function to report error before exit
  This is designed to improve and unify error handling for
  
  allocation failures for the many (often small) allocations that we have
  
  in the fftools. These typically either don't return an error message
  
  or an error message that is not really helpful to the user
  
  and can be replaced by a generic error message without loss of
  
  information.

• How to get FFPLAY to stop/exit after set time of showing streaming ?

  9 octobre 2022, par PiBer2

  I am playing streaming from an IP camera with FFPLAY, using a Raspberry Pi with an HDMI monitor connected to it. Everything goes well (window placing, resizing, etc), except that I need FFPLAY to stop afer N seconds.

  


  I have tried a few things, including

  


  env DISPLAY=:0 ffplay -rtsp_transport tcp -left 0 -top 0 -noborder -t 00:00:10 -i rtsp://user:pass@192.168.4.157:46449/live -vf scale=480:240 -an -autoexit


  


  The issue is that at 10 seconds, the screen image freezes but FFPLAY does not exit. It keeps running and incrementing the time count, even when the image is frozen.

  


  This is for instance 50 seconds after the start :

  


  


  Input #0, rtsp, from 'rtsp ://user:pass@192.168.4.157:46449/live' :
  
Metadata :
title : RTSP Session/2.0 Duration : N/A, start : 0.000000, bitrate : N/A
Stream #0:0 : Video : h264 (Baseline), yuv420p(progressive), 1280x720, 25.08 tbr, 90k tbn, 180k tbc
Stream #0:1 : Audio : pcm_alaw, 8000 Hz, 1 channels, s16, 64 kb/s

  


  


  


  50.93 M-V : -4.542 fd= 0 aq= 0KB vq= 0KB sq= 0B f=0/0

  


  


  I have also tried to pipe from FFMPEG to FFPLAY, with exactly the same result :

  


  ffmpeg -rtsp_transport tcp  -t 00:00:10 -i rtsp://user:pass@192.168.4.157:46449/live -vf scale=480:240 -an -f matroska - | env DISPLAY=:0 ffplay -left 0 -top 0 -noborder -


  


  FFPLAY keeps running ok, as I can stop it with Esc from the GUI.
