• openRTSP TCP 100% Cpu

  25 avril 2014, par user1199722

  First thanks for the great work for live media group.
  I am currently facing a problem with OpenRTSP utilizing cpu 100%.
  I am using the following commands to stream from remote ipcamera through internet. It works fine with local cameras.
  But when I try to stream from Internet IP camera (720p), At random times openRTSP start uses 100% cpu and stops output of streaming. The process is not exiting it stay with 100% cpu.

  I have observed that stream stops with a series of "c9c99c999......."
  I am using TCP streaming of rtsp.
  Please find the command that i am using.

  openRTSP -d 60 -v -t -c -b 800000 | /bin/ffmpeg -r 15 -i - -codec copy -hls_list_size 65535 -hls_time 5

  Please provide your suggestions regarding the problem
  Waiting for your valuable pointers.

• Access to folders on Ubuntu-based Rails server (keep getting "No such file..")

  13 avril 2012, par Stpn

  I am setting up Rails+ffmpeg on Ubuntu and I keep getting

   Errno::ENOENT
  
   No such file or directory..

  The setup is as follows :

  /home/username/RailsApp
  /home/username/videos/

  I am trying to run ffmpeg to write to /home/username/videos and I used "/home/username/videos/" and " /videos/" but no luck..

  What am I missing ?

  "www-data" user is included in "username" group..

  Rails app works fine otherwise..

  Any input greatly appreciated !

  Thanks !

• Concatenating on Windows throws "Invalid data found when processing input" while it works on Mac and Linux

  15 février 2020, par miguelmorin

  I need to run a command with a nightly build of FFMPEG to report a bug on the concat protocol. I found it difficult to compile from source with libx264 support on Linux, and I want to spare my Mac computer, so I use the nightly build on Windows from Zeranoe.

  I call this command to concatenate the files :

  ffmpeg -safe 0 concat -i files_to_combine -vcodec libx264 show.mp4

  where files_to_combine is :

  file ./short_DSC_0013.MOV
  
  file ./short_DSC_0014.MOV
  
  file ./short_DSC_0015.MOV
  
  file ./short_DSC_0016.MOV
  
  file ./short_DSC_0017.MOV
  
  file ./short_DSC_0018.MOV
  
  file ./short_DSC_0019.MOV

  I call this command from the directory containing the video files and files_to_combine.

  On Windows with a nightly build, I get the error :

  files_to_combine : Invalid data found when processing input
  

  I changed file ./DSC_0013.MOV to these options, all with the same error :

  file 'short_DSC_0013.MOV'
  
  file '.\short_DSC_0013.MOV'
  
  file 'F:\short_DSC_0013.MOV'

  How can I debug this error, or what is the syntax for concatenating on Windows with a nightly build ?

  Update with log-level 48

  I ran the same command with -v 48 and got :

  Update because of wrong command

  I had mistyped the command. The right command has a -f in front of concat, which I found because the accepted answer was able to make the command work in a similar environment :

  ffmpeg -safe 0 -f concat -i files_to_combine -vcodec libx264 show.mp4
