• How to put a video inside a frame and record whole thing as a video ?

  7 octobre 2024, par crysis

  I have a video. I want to create a new video such that the video plays inside a frame similar to this screenshot. Loom recording does this. Most of the screen recorders do this.

  


  

  


  This screenshot is of the video. This is done in most of the screen recorders. Here is what I'm thinking

  


  

  • render video on a canvas with the background.

  


  • Play the video

  


  • Use mediarecorder API to record a new video.

  


  


  I don't have good understanding of frontend development. Is that how it is generally done or I need to use ffmpeg ? I would really appreciate any guidance here.

  


• ffmpeg returned non-zero exit status. Check stdout Coldfusion

  30 mars 2017, par Abdul Rauf

  I have an coldfusion application. I am converting recorded video from mobile through ffmpeg and coldfusion. Here is the ffmpeg command which i am running.

  ffmpegPath -i "inputfile" -vcodec libx264 -acodec aac "OutputFile"

  Output file type is mp4. I want to convert my all videos to mp4 with h.264 and ACC sound. So that it will work on all platforms.

  I am getting the following error :

  java.io.IOException: ffmpeg returned non-zero exit status. Check stdout.

  Here is the CF code that i am running.

• C# FFmpeg Cannot process request because the process (11536) has exited

  30 avril 2016, par Martin Mazza Dawson

  I’m trying to convert an .ogg file to .mp3. I am following this link to do so : How to call ffmpeg.exe to convert audio files on Windows Azure ?

  I get the error message :

  Cannot process request because the process (11536) has exited.

  The ffmpeg.exe is in my root dir and it works when I convert the .ogg file to .mp3 in the command prompt, the ogg_path also has the correct bytes written to it when I check using debugging.
  Can anyone tell me what I am doing wrong please ?
