• How to fix : Frame rate differs from source after encoding certain mp4 videos to wmv

  25 juin 2019, par hpenhp

  I’m having trouble with a usually working ffmpeg script for encoding mp4 and more to wmv. The goal is to keep it like the original, except for the resolution (smaller) and the format (wmv).

  When it usually works for a lot of videos, on some of them it doesn’t... and i would like to understand and avoid that.

  I tried several things, forcing the framerate for the output, using -vsync 2 option, -vsync 0 also.. noone of that fixed the issue.

  An other thing, worth adding, is that the fps value from media info is good (24 fps) on the output like the input, but through the M$ windows explorer, it says 30 frames per sec, and when you play the video you see that the text that was matching the input doesn’t match the output any more (because of the fps mismatching).

  Below the script i use :

  ffmpeg -threads auto -i input.mp4 -s 480*320 -b:v 1000k -vcodec msmpeg4 -acodec wmav2 -f asf output.wmv

  Here is the ffmpeg log :

  EDIT :
  My workaround was to encode to MPEG, doing this, i’m able to read my file and the frame rate is same as source. If someone knows why it couldn’t keep the original framerate in wmv, i’m still interested to know.

• ffmpeg -Video live feed

  22 juin 2019, par Rajeev

  I am using AMCREST security camera at my home. My objective is to get a live feed one of IP camera attached to my NVR to a webportal using rtsp ://My environment is Raspberry pi.

  I am able to successfully start the ffserver but conversion is failing when I am trying pass the input video and stream it to video.ffm

  I have tried various combination of parameters in the command but the below one seems to be very close where I got only one error ( av_interleaved_write_frame() : Connection reset by peer)

  My expectation is that ffmpeg will start writing data to video.ffm located in /tmp directory so that I can read the data from our browser or vlc media player by just entering the following link
  http://localhost:8090/stream

  ****** Update after 2 hr******

  I made slight change to the command parameter and my out changed as well.What it looks like the temporary video file that got generated in /tmp folder is not getting consumes by video.ffm ( I may be wrong in my analysis)

• Laravel Process() with FFMPEG times out for any video that is even kind of large

  16 août 2024, par Hunter

  I am creating an application that lets users upload video files, and once they do it will convert them all to .mp4's (it does some other things, but since this first part of the code is breaking before it gets a chance to reach the other stuff, and the process for each is pretty similar, lets just discuss this issue).

  



  Once a user submits, it gets sent to GameController@store. Below is a code sample (the one that keeps getting sent back to me as problematic) from the controller :

  



  $process = new Process(env('APP_FFMPEG', 'ffmpeg') . ' -i ' . $fileURL . ' -f mp4 -vcodec libx264 -preset medium -profile:v main -c:a aac -movflags +faststart ' . $newFileName . ' -hide_banner');
              $process->setTimeout(360);
              $process->setIdleTimeout(60);
              $process->run();
              if (!$process->isSuccessful()) {
                throw new ProcessFailedException($process);
              }


  



  I am using the Symfony Process() class to run the FFMpeg conversion. The weird thing is, when I run this with a 1 or 2 second video, it goes without a hitch. This, to me, rules out issues like path problems, permission problems, etc. Multiple file types work with this, as long as they are very short. As soon as I put in a video that is even around 1min, it returns with this :

  



  The process "/usr/local/bin/ffmpeg -i http://localhost/storage/team_1_folder/game_26/team_1_game_26_vid_1.mp4 -f mp4 -vcodec libx264 -preset medium -profile:v main -c:a aac -movflags +faststart storage/team_1_folder/game_26/convertedVideo_1.mp4 -hide_banner" exceeded the timeout of 360 seconds.


  



  Now, notice that it says 'timeout of 360 seconds'. That is because I have also edited ALL of the possible timeout constraints, as well as the file size constraints that I can think of. Here is what I have done :
  

  



  -Changed php.ini (in my MAMP installation) values :
  
—max_execution_time = 300 (default was 30)
  
—memory_limit = 1280M (default was 128)
  
—post_max_size = 800M
  
—upload_max_filesize = 3200M
  
-max_input_time=300
  

  



  -In the GameController (code above)
  
—$process->setTimeout(360) ;
  
—$process->setTimeout(360) ;
  

  



  After all that, with a big file, the thing will just stall for the 6 minutes that I have set on the timeout thing, and then send an error. Is FFmpeg just stalling, or is this a process issue ? Who knows. Errors surrounding these things are just beautifully vague.

  



  I have tagged Laravel, PHP, and FFmpeg in hopes that someone will recognize this issue. I know that Process() is sending me the error, but since it is sending me a timeout, I don't know what is at fault.

  



  I'm not ruling anything out, so hit me with ideas, even crazy ones !

  



  Edit
Here is the output of the -report. I cut some of it off because the end part gets repetitive and goes for literally 1000 lines :
