  Before it was that there was no ffmpeg buildpack on heroku, I added it with
https://elements.heroku.com/buildpacks/jonathanong/heroku-buildpack-ffmpeg-latest

  


  But now I just get state changed and see no errors. Any help would be greatly appreciated !

  


• gst-inspect-1.0 do not see avdec_h264

  16 octobre 2020, par Marat Zakirov

  Previously I installed gstreamer via conda and its (good) plugins
next I installed gst-libav via sudo apt-get install gstreamer1.0-libav next I used apt-file list gstreamer1.0-libav to see installation path and found it to be /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ next I read running gstream manual and then

  


  GST_PLUGIN_PATH=/usr/lib/x86_64-linux-gnu/gstreamer-1.0/ gst-inspect-1.0 avdec_h264

(base) marat@user-System-Product-Name:~$ ls -lh /usr/lib/x86_64-linux-gnu/gstreamer-1.0/ | grep av

  It found many new modules but didn't found avdec_h264. What I am missing ?

  


  UPDATE :

  


  I just want way to use gstreamer via conda virtenv python appliation. If you know valid way to do so I will consider your reply as answer.

  


• Mac terminal command to list files and sort by date to use in ffmpeg

  22 septembre 2020, par Jeff

  I am using a gopro to film a bunch of videos. I want to then take those videos directly from the SD card folder and concatenate them into a single video (bypass an editor) by using FFMPEG.

  


  I'm currently able to stitch together "chaptered" videos with the following example command on my Mac (10.13) :

  


  ffmpeg -f concat -safe 0 -i <(for f in /sdcardfolder/100GOPRO/GH*488.MP4; do echo "file '$f'"; done) -c copy /folder/video.mp4

  


  The reason for this is that the ffmpeg command requires a text file that looks like this :

  


  


  file '/folder/GH016992.MP4'

  
file '/folder/GH036990.MP4'

  
...

  


  


  The real command is this, which generates the list of files in the right format with file in front of each one and can be embedded into the ffmpeg command :

  


  for f in /Volumes/GoPro8/DCIM/100GOPRO/GH0*71*.MP4; do echo "file '$f'"; done

  


  I want to add 2 changes to this :

  


  


  1. List the files in date order (ascending) : I want the list of files to be in date order. But I can't figure out how to add a -sort or something to the for f in command.

     


  


  2. Allow a more robust set of file matching/filtering : Right now I can add basic regex like GH*488.MP4 or, with chapters which increments the first number, something like GH0[123]488.MP4 would work to just get the first few. But when I change it to be more flexible like GH0[0-9]71[0-9][0-9].MP4 - which would be necessary to match all files that were recorded yesterday, but nothing before then, the command doesn't like this regex. It seems to only accept a *.

     


  


  


  I looked at a few examples like https://opensource.com/article/19/6/how-write-loop-bash but there wasn't much more than just listing files.

  


  This boils down to a terminal command and isn't really related to FFMPEG but I hope it's helpful context.

  


  I imagined it would be something like this, but this definitely doesn't work :

  


  for f in (find /Volumes/GoPro8/DCIM/100GOPRO/GH0[0-9]71[0-9][0-9].MP4 -type f | sort); do echo "file '$f'"; done

  


  I'd appreciate any help ! Thanks !

  


  Update

  


  It looks like sorting isn't easy with Mac tools so I gave up and wrote a much simpler Ruby script that could execute everything for me. This is not really an answer to my question above but it is a solution.

  


  Here I can easily write the text file necessary for ffmpeg and I can also filter files with a regex on the name, filter for a particular date, and size. Then, via the script, simply execute the ffmpeg command with args to concat files. I can also have it immediately resample the file to compress it (gopro videos are giant and I'm ok with a much lower bitrate if I want to save raw footage).

  


  I got lucky with this Dir.entries in Ruby - it seems to automatically sort by date ? I don't know how to sort it otherwise.

  


  PATH = '/Volumes/GoPro8/DCIM/100GOPRO/'
NEW_FILENAME = '/folder/new-file.mp4'
video_list = '/folder/ffmpeg-list.txt'

# create the text file
File.delete(video_list) if File.exist?(video_list)
i = 1
Dir.entries(PATH).each do |f|
    d = File.mtime(PATH + f)
    size = File.size(PATH + f)
    if f.match(/GH0.*.MP4/) && d.to_s.match(/2020-07-30/) && size.to_i < 1000000000
        puts "#{i}\t#{f}\t#{d}\t#{size}"
        File.write(video_list, "file #{PATH + f}\n", mode: "a")
        i= i+1
    end
end

command = "ffmpeg -f concat -safe 0 -i #{video_list} -c copy #{NEW_FILENAME}"

puts "executing concatenate..."
puts command
system(command)
