• Hikvision NVR video conversion ffmpeg

  6 août 2024, par astralmaster

  I have a Hikvision NVR that stores security camera footage that I need to display on a website. I know that Hikvision uses proprietary H.264 codec that makes it impossible to play (coherently) in popular video players, like VLC, unless you install that codec everywhere you play it.

  



  My plan was to transcode the video using ffmpeg to regular H.264 codec and AAC for audio but the produced file has the same issues as the original - no audio when playing and very disruptive video. 
So the question is, does ffmpeg support encoding from Hikvision video/audio codecs ? Or perhaps should try to convert to different web-capable codecs using ffmpeg ?
My ffmpeg command looks like this :

  



  ffmpeg -i C:\1.mp4  -c:v libx264 -preset fast -crf 30 -b:v 200k -c:a aac -strict experimental -movflags faststart -threads 0 C:\2.mp4


  



  EDIT : What's interesting is that ffplay.exe opens and plays the original video files with no problem whatsoever, even on a computer where Hikvision codecs are not isntalled, therefore I figured conversion should be possible as well ?

  



  Mediainfo output of the video file in question :

• Android : Pass video path to FFmpeg

  7 janvier 2016, par marian

  I have developed an app that play video from gallery. I would like to add watermark using FFmpeg command in the video selected. But I do not know how to pass the path to the FFmpeg command. I could not find proper tutorials or reference regarding this. My coding are as follows :

  ffmpeg command :

  String[] complexCommand = {"ffmpeg","-y" ,"-i",  "/sdcard/videokit/in.mp4","-strict","experimental",
  
              "-vf", "movie=/sdcard/videokit/watermark.png [watermark];" +
  
              " [in][watermark] overlay=main_w-overlay_w-10:10 [out]","-s",
  
              "320x240","-r", "30", "-b", "15496k", "-vcodec", "mpeg4","-ab",
  
              "48000", "-ac", "2", "-ar", "22050", "/sdcard/videokit/out1.mp4"};

  Tis command is from a sample project. How do i pass the video path to this command ? I do not know how to edit the command to support my requirement. Can someone guide me through this. Any help will be really helpful. Thank you.

• FFMPEG FFBROBE Get Frame Count On Powershell [duplicate]

  27 avril 2020, par ilham zacky

  I am new to FFmpeg, I have some audio and video files, I need to get the duration with frames, I need it in this format H:M:S:F - "00:00:00:00", I am using Powershell

  



  currently, my duration works, but instead of frames, it prints a decimal value.
note : in my output maximum number of frames should be 30

  



  This is my code

  



  $audioId = "$id.m4a"
$videoId = "$id.mp4"

$duration1 = if ((ffprobe -i $audioId 2>&1 | Out-String) -match 'Duration:\s+([\d:"."]+)') { $matches[1] };

$duration = if ((ffmpeg -i $videoId 2>&1 | Out-String) -match 'Duration:\s+([\d:"."]+)') { $matches[1] };

$newduration1 = ("$duration1").Replace(".",":")
$newduration = ("$duration").Replace(".",":")

echo $duration1 
echo $duration



  



  my output be like

  



  00:00:03.48
00:00:03.46
