  • Audio Video Editing in Python : How to do it ? [on hold]

    12 mai 2019, par DoakCode

    Does anyone know how to do it ? It’s a bit more complex then then the usual docs I’ve read, so I don’t know where to start and I’d appreciate someone leading me to the right docs or the right path.

    The software should be doing following :

    1. Taking a background picture and making it blurred -> The background
    2. In the front should be :
      1. A picture
      2. Text
      3. A progressing timer (which displays the current status of the video)
    3. Last, but not least, audio should be added to the video or vice versa as the video is supposed to end when the audio ends to round things up.

    As this all is pretty complex editing for a python programme, I don’t know which library(ies) to use.. If someone has a solution / idea please reply !

    x86/vvc_alf : avoid overwriting for non-16 aligned widths

    Previously, the code allowed overwriting on 16-aligned blocks, which was suitable when there were
    
no picture's virtual boundaries because both CTU sizes and strides were 16-aligned. However, with
    
picture's virtual boundaries, each CTU is divided into four ALF blocks, leading to potential issues
    
with overwriting later CTUs.
    

    In cases involving picture virtual boundaries, each ALF block is 8-pixel aligned.
    
For luma, we consistently ensure an 8-aligned width. For chroma in 4:2:0 format,
    
we need to account for a 4-aligned width.
