• FFMPEG Drag and Drop sh file

  29 avril 2021, par WFCDefi

  On Windows I have a simple batch file which I drop video files onto to convert to webms, it saves a lot of time as I prefer to just use the same configuration and don't care much about the names.

  


  @echo off 
echo. 
ffmpeg -i %1 -c:v libvpx-vp9 -quality good -cpu-used 2 -b:v 5000k -qmin 15 -qmax 45 -maxrate 500k -bufsize 1500k -framerate 60 -threads 8 -vf scale=-1:1080 -c:a libvorbis -b:a 192k -f webm %1.webm 
pause


  


  I know the .bat file won't really work in Linux (I'm on pop os so pretty much Ubuntu) so with the other lines removed and the %1 changed to $1 it works. It won't do anything if I try dragging and dropping a video file onto it though.

  


  I can type sudo then drag and drop the .sh file followed by a video into a terminal and press enter and it will have the same effect as dragging a video file onto a bat file in Windows.

  


  Is there a way to recreate dragging and dropping a file directly onto another and it executing in Linux or is the terminal the only way ?

  


• Re-creating/matching ffmpeg settings

  8 novembre 2013, par Pete Helgren

  I have an MP4 file that plays pretty much on every browser using either HTML5 or flash fallback (using mediaelement.js). I also have a series of additional video files that I would like to have "match" the one file that does play consistently but I haven't been able to match the ffmpeg settings so it produces a like file. I used ffprobe and got the following results on the file that plays successfully :

  Following a few guides I found online, I am using the following ffmpeg settings :

  ffmpeg -i {input file name} -y -acodec aac -ac 2 -strict experimental -ab 64k -s 320x240 -vcodec libx264 -pix_fmt yuv420p -preset slow -profile:v baseline -level 30 -maxrate 300k -bufsize 600k -b:v 300k -f mp4 -threads 0 -movflags +faststart {output file name}

  That command produces the following output :

  ffmpeg -i "testin.mp4" -y -acodec aac -ac 2 -strict experimental -ab 64k -s 320x240 -vcodec libx264 -pix_fmt yuv420p -preset slow-profile:v baseline -level 30 -maxrate 300k -bufsize 600k -b:v 300k -f mp4 -threads 0 -movflags +faststart testout.mp4

  The one problem with the incantation above is that on iPad's and iPhones and some Android tablets all you hear is the audio with no video. But the file listed above (contents of the ffprobe) does not have that problem, it WILL play on an iPad, iPhone, Android tablet. I researched causes for "audio, no video" and the recommendations were all over the deck. But, the file listed in the ffprobe DOES play, so if I can match those settings described by the ffprobe for all of the other videos, they should play consistently as well. My challenge is to match the ffprobe settings using ffmpeg and there doesn't seem to be a 1 to 1 match between what I see in ffprobe and the corresponding settings in ffmpeg (a nice utility would be to have ffprobe output the ffmpeg settings that could be used to create a file of similar format).

  I walked through the ffprobe documentation but couldn't find anything that would produce a format that could be used as input to ffmpeg. Suggestions ?

• nginx RTMP to HLS : FFMPG error when trying multiple bitrate output [closed]

  28 mai 2014, par user3685074

  I’m currently trying to convert my RTMP Livestream into a HLS with 3 quality-settings.

  I followed this guide

  I’ve compiled my own FFMPEG and it’s working if I just convert 1 file.
  It seems libx264 isn’t able to do multiple encodings at the same time ?

  I’m using these command :

          exec /usr/local/bin/ffmpeg -i rtmp://localhost/src/$name 
  
          -c:a libfdk_aac -b:a 32k   -c:v libx264 -b:v 128K -f flv rtmp://localhost/hls/$name_low 
  
          -c:a libfdk_aac -b:a 64k   -c:v libx264 -b:v 256K -f flv rtmp://localhost/hls/$name_mid 
  
          -c:a libfdk_aac -b:a 128k  -c:v libx264 -b:v 512K -f flv rtmp://localhost/hls/$name_hi  2>>/tmp/ffmpeg.log;

  this is the output :
