  • Background Video Processing with Rails

    23 octobre 2013, par Matthew Snyder

    I am trying to get uploaded videos to be converted in the background, running windows. Some of what I am using :

    gem 'paperclip'
    
gem 'delayed_job_active_record'
    
gem 'ffmpeg'

    I have edited the registry to allow the ffmpeg command to be ran from anywhere, I get a popup that I assume is ffmpeg because it goes away too quickly, guess the command is wrong so if anyone knows what's wrong with it please let me know. But the real problem is that it just hangs there, it says :

    [2012-12-09 22:47:03] ERROR invalid body size.

  • FFmpeg - Extracting video and audio from transport stream file (.ts)

    25 juillet 2015, par Passepartout

    I wish to extract the audio and video of a certain program in a transport stream file (.ts) by specifying its PID without losing quality and using the same codec in the resulting file (the output file is a MPEG).

    Is that even possible with FFmpeg ? If so, how can I do it ?

    So far, I’ve come to this command :

     ffmpeg -i tsfile.ts -vcodec copy -acodec copy -q:v 1 output.mpg

    Edit : Note that the file output.mpg is created. The file contains the video but the audio isn’t attached (no sound). Also, I am unable to specify the program PID to extract.

    Edit 2 : Here’s the output of ffmpeg -i tsfile.ts

  • ffmpeg transcode video with dts-ma to ac3

    12 juin 2015, par John Galt

    I’m trying to take a video that has an h264 video track and a dts-ma audio track and and get out an .m4v file with :

    h264 video track
    DTS-ma audio track
    AC-3 5.1 Audio track

    I’m attempting to just copy the video and the dts-ma audio track and then have it convert the AC-3 audio track

    I’m getting an error Unable to find a suitable output format for 'ac3' from this command :

    ffmpeg -i "input.mkv" -map 0:0 -map 0:1 -map 0:1 -map 0:1 -c:v copy -c:a:0 copy -c:a:1 -acodec ac3 -ac 6 -ab 448k -c:a:2 -acodec ac3 -ac 6 -ab 256 -ar 48000 "output.m4v"

    (this is generated by my C# app)

    this for a different file that has h264 and ac3 already in it works fine :

    ffmpeg -i "input.mkv" -map 0:0 -map 0:1 -c:v copy -c:a:0 copy "output.m4v"

    Obviously it’s not doing a conversion.

    Here’s the full results of the first command :
