Getting error while saving the video

[usmanarif]

I am getting following error while saving the video error while running command ffmpeg -i "/tmp/ed48c144522ed8beaba94863c34b0f9d20150423-3314-3r52bx.mp4" -s 640x480 -y "/tmp/ed48c144522ed8beaba94863c34b0f9d20150423-3314-3r52bx20150423-3314-1ok2yh8.flv": Command 'ffmpeg -i "/tmp/ed48c144522ed8beaba94863c34b0f9d20150423-3314-3r52bx.mp4" -s 640x480 -y "/tmp/ed48c144522ed8beaba94863c34b0f9d20150423-3314-3r52bx20150423-3314-1ok2yh8.flv"' returned 1. Expected 0

Error is in this line while updating: if @worker.update(worker_params)

Following is my code:

Gemfile gem 'paperclip-av-transcoder'

worker.rb has_attached_file :video, :styles => {:medium => { :geometry => "640x480", :format => 'flv' },:thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 } }, :processors => [:transcoder]

workers_controller.rb def update respond_to do |format| if @worker.update(worker_params) format.html { redirect_to @worker, notice: 'Worker was successfully updated.' } format.json { render :show, status: :ok, location: @worker } else format.html { render :edit } format.json { render json: @worker.errors, status: :unprocessable_entity } end end end def worker_params params.require(:worker).permit(:video, :user_id, :profile_photo, :worker_spoken_languages_attributes => [:id, :worker_id, :spoken_language, :_destroy]) end

show.haml %p %strong Video: = video_tag @worker.video.url %p

Please tell if I am missing anything

[attenzione]

can you please take your mp4 file and run command from your command line (terminal) directly ffmpeg -i your_mp4.path.mp4 -s 640x480 -y out.flv and write down output

@attenzione I also too had this issue. So given your instructions above I tried your above instructions:

Prerequisite: I executed this command in the same directory as where the video was located.

@attenzione Interestingly though I was able to overcome the above error by commenting out in my model: :medium => { :geometry => "150x85#", :format => 'flv' }. For some particular reason having that line included in the model a per the readme causes an error. FYI this is the version of the gems that I have in my Gemfile.lock

av (0.9.0)
      cocaine (~> 0.5.3)
paperclip-av-transcoder (0.6.4)
     av (~> 0.9.0)
     paperclip (>= 2.5.2)

Although as mentioned once I try to upload another video I encounter:

error while running command if command -v avprobe 2>/dev/null; then echo "true"; else echo "false"; fi: Command 'PATH=/usr/bin:$PATH if command -v avprobe 2>/dev/null; then echo "true"; else echo "false"; fi' returned 2. Expected 0
Here is the command output

The above error touches base with #16 also. I too am running Paperclip 4.2.1

[attenzione]

@davidpatters0n seems, ffmpeg flv1 library is broken?

[davidpatters0n]

@attenzione I see and there is no way around this issue?

[attenzione]

Try to reinstall, recompile ffmpeg or try to use avconv

[davidpatters0n]

@attenzione I uninstalled the av gem and reinstalled it. what do you mean by recompile ffmmpeg? And what do you mean by try and use avconv? Just need clarity. Thanks

[attenzione]

this gem uses external application - ffmpeg or avconv, you need to reinstall it, not gem

@attenzione so I decided to uinstall ffmpeg and install avconv. Having installed avconv i was able to run the avconv command via my terminal: avconv -i some_file.mp4 output.mp4 and this seemed to work. So I know for a fact that aconv is working. However now that installed avconv and try to use paperclip-av-transcoder with the following setup in my model:

has_attached_file :video, :styles => {
  #:medium => { :geometry => "150x85#", :format => 'flv' },
  :thumb => { :geometry => "100x100#", :format => 'jpg', :time => 10 }
  }, :processors => [:transcoder]

Interestingly when i submit my form the first time it uploads the video fine. If i attempt to upload the video again it fails.

I now have this working https://github.com/ruby-av/paperclip-av-transcoder/issues/10#issuecomment-115842644 hopefully it helps others and closes this issue along with #16
