• 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

• When Kxmovie plays .rm format file, the audio does not work fine

  6 septembre 2016, par Bruce Jordan Wang

  I used third party video player KxMovie to play video in my app, the video streams fluently but the audio keeps on-and-off in a regular way, how to solve it ? What’s the possible reason for this problem ?

  Parameters about the .rm format video :

  

• ffmpeg encoded video don't work on mplayer

  15 septembre 2022, par Turgut

  I've made a C/C++ program that encodes a video. It takes several input videos with presumably different fpses, then encodes them as a single video with a different single fps. For example you can give 2 videos with fpses 30 and 60 respectively then set output fps to 120. This works fine under normal circumstances.

  


  However when ran through mplayer on a different pc then mine, it says the following :

  


  

  

As seen here it says that audio is at 30 while video is at 15. Normally I would just shrug this off however it works on any other video player on the same computer. So I would assume that mplayer is at fault and shrug it off, but it works on my computer's mplayer.


  


  Is this about my video encoding ? Do I need to change the header of the video ? Here is how I set the time :

  


  AVStream* st;&#xA;st->time_base =  av_d2q(1 / fps, std::numeric_limits<int>::max());&#xA;&#xA;</int>

  


  What could be the problem ?
