  • Monitoring ffmpeg two-passes encoding

    31 décembre 2024, par Hodol

    I'm new in FFMPEG.

    


    According to the official guide, https://trac.ffmpeg.org/wiki/Encode/VP9 I use the following command to convert a large h.264 file :

    


    ffmpeg -i input.mp4 -c:v libvpx-vp9 -b:v 0 -crf 30 -pass 1 -an -f null /dev/null
ffmpeg -i input.mp4 -c:v libvpx-vp9 -b:v 0 -crf 30 -pass 2 -c:a libopus output.webm


    


    However, the pass-1 takes too long time and it does not log progress. With -report option I can see something is in progress but I don't know how long I should wait.

    


    Here's questions :

    


      

    1. Is there any way to see the progress of 1-pass ?

      2. 


    2. Is there any way to speed up the process ?

      3. 


    


    Thank you,

    


  • Displaying javacv Frame class

    3 avril 2018, par shubham jaiswal

    I want to display a javacv Frame object directly into a gui container without converting into a buffered image or any of the jpeg/bmp as mentioned in https://docs.oracle.com/javase/8/javafx/api/javafx/scene/image/Image.html. Is there any way in which it can be achieved ?

    I want to do this as I have multiple video streams to be displayed.Currently the best performance that could be achieved is using JFrame and pixelwriter.It consumes around 8% CPU. I want to bring it to below 4% and so need a method to display the Frame object directly.

    If anyone could suggest an alternative GUI or language, it still helps.

    Regards & Thanks.

  • How to encrypt webm file using Clear Key to play with Google's Shaka Player ?

    23 janvier 2017, par Nam Pham

    I’m developing a small system which will be used to streaming protected content over the web with MSE/EME API.

    This is some tools I’m using :

    I can create .webm file and package them using shaka-packager into mpd file in order to feed to shaka-player. But following by the Clear Key section in the Shaka docs I have to encrypt webm file require pair of KeyId and Key.
    By using webm_crypt, I can created encrypted content by follow this document on 2.2.7 but I have no idea how to get the key pairs for the shaka-player DRM system.
