• Why A .FLAC File Converted by FFMPEG Cause File Explorer Unresponse on Windows 10 [closed]

  20 juillet 2022, par Alex King

  My File Explorer Always showing "Working on it."
I've tried many resolutions.
First,I disconnect my NAS drive. seems fine.
I test many times on diffirient windows 10/11 versions.
I thought it was SMB problem on windows. But i was wrong.

  


  Today I'm using FFMPEG convert .wav to .flac.

  


  .\ffmpeg.exe -i $Source -c:a flac $Dest 


  


  Just simple like this. Blow my computer up.

  


  Even worse, explorer.exe crash after I'm trying to open FF output folder.

  


  It's not the poblem from "Quick access" or "Search Index".

  


  I'm now 100% percent confirm the flac files that ffmpeg made will cause file explorer crash.

  


  I can't solve it without knowing the reason.

  


  Might related to audio file tag vorbis ?

  


  This is my FFMPEG info

• avformat/mov : discard data streams with all zero sample_delta

  6 juillet 2022, par Zhao Zhili

  avformat/mov : discard data streams with all zero sample_delta
  Streams with all zero sample_delta in 'stts' have all zero dts.
  
  They have higher chance be chose by mov_find_next_sample(), which
  
  leads to seek again and again.
  For example, GoPro created a 'GoPro SOS' stream :
  
    Stream #0:4[0x5](eng) : Data : none (fdsc / 0x63736466), 13 kb/s (default)
  
      Metadata :
  
        creation_time : 2022-06-21T08:49:19.000000Z
  
        handler_name : GoPro SOS
  With 'ffprobe -show_frames http://example.com/gopro.mp4', ffprobe
  
  blocks until all samples in 'GoPro SOS' stream are consumed first.

• FFmpeg command to draw text hindi font is working fine in windows command prompt but Batch script and simple CPP program in NOT working

  1er juillet 2022, par Abdullah Farweez

  Below ffmpeg command in working fine in command prompt

  


  ffmpeg -i video.mp4 -filter_complex "drawtext=fontfile=Khula-regular.ttf:fontsize=60:fontcolor=blue:text=अगला एपिसोड देखने के लिए जल्दी से फॉलो करें:x=30:y=200" output.mp4


  


  giving expected result


  


  But if we run it as a bat file, it is not giving the expected output

  


      ::bat script start 
    @echo off
    ffmpeg -i video.mp4 -filter_complex "drawtext=fontfile=Khula-Regular.ttf:fontsize=60:fontcolor=blue:text=अगला एपिसोड देखने के लिए जल्दी से फॉलो करें:x=30:y=200" output.mp4
:: bat script end


  


  This the CPP program which calling the ffmpeg command via system method

  


  #include <iostream>&#xA;#include <cstring>&#xA;#include &#xA;&#xA;using namespace std;&#xA;&#xA;int main()&#xA;{&#xA;  string command = "ffmpeg.exe -i video.mp4 -filter_complex \"drawtext=fontfile=Khula-Regular.ttf:fontsize=60:fontcolor=yellow:text=अगला एपिसोड देखने के लिए जल्दी से फॉलो करें:x=30:y=200\" output.mp4";&#xA;  system(command.c_str());&#xA;  return 0;&#xA;}&#xA;</cstring></iostream>

  


  same behavior as bat script.
