  • vlc runtime frame manipulation

    9 avril 2017, par RonTLV

    Regarding VLC, where is the best place to hook on each video frame ?

    I’ve cloned VLC and compiled successfully, and I understand that VLC has modules that it loads. I also noticed that VLC downloads ffmpeg and compile it.

    Should I write a VLC Module or ffmpeg filter ?

    Help is appreciated

  • Normalize samples with ffmpeg

    5 avril 2017, par Steva

    I am writing application for music analysis. I wrote resampling module relying on ffmpeg. Currently, I have AV_SAMPLE_FMT_S16 but later I have converting to float, which can be time consuming.

    Because I need samples to be in some reasonable interval I need to do some kind of normalization, for AV_SAMPLE_FMT_FLT samples.

    So, how I can normalize samples which I get when I select AV_SAMPLE_FMT_FLT. Ideal interval would be -n to n, where n is greater than equal of 1.f

  • Rails 4.2.8 Using Paperclip With Resque

    27 mars 2017, par AntonioMarquis

    My application uploads training videos to a S3 bucket. I need the transcoding videos to be processed in the background so they don’t tie up the application. I want to use Resque on my dev machine and Heroku. But my jobs continue to fail.
