    Le chemin d’un document audio ou vidéo dans SPIPMotion est divisé en trois étapes distinctes.

  • Show video while saving it

    13 septembre 2022, par Mohamed Adel El-Badry

    I have a folder full of images, I need to save these images into the video while doing so I want to show the user the video being played from these images (frames). I can run two separate processes one for the saving and one for the showing but this is not what I am looking for, I want to do both in one step. If you know a solution please let me know.

    


    My code uses C++ with OpenCV but feel free to share with me any code written with any language, or event a concept.

    


    I use gStreamer, ffmpeg as well for the video generation, so I am not looking how to save a video or how to show the video I am looking for a process that can do both in one operation.

    avcodec/utvideodec/enc : Fix edge case of creating Huffman table

    The Ut Video format stores Huffman tables in its bitstream by coding
    
the length of a given symbol ; it does not code the actual code directly,
    
instead this is to be inferred by the rule that a symbol is to the left
    
of every shorter symbol in the Huffman tree and that for symbols of the
    
same length the symbol is descending from left to right. With one
    
exception, this is also what our de- and encoder did.
    

    The exception only matters when there are codes of length 32, because
    
in this case the first symbol of this length did not get the code 0,
    
but 1 ; this is tantamount to pretending that there is a (nonexistent)
    
leaf of length 32. This is simply false. The reference software agrees
    
with this [1].
