    9 mars 2015, par Alex Converse

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c



    Don’t waste time partitioning skip superblocks.

    Force 64x64 partitioning when a whole superblock is SEGMENT_LVL_SKIP. This
    drops encode times of screens mostly at rest by 20%.

  • converting audio from mp4 to wav and croping in the process using python

    7 mars 2019, par fastali

    I am looking for a package where I can use to convert the audio file from mp4 to wav simultaneously while also cropping the file using python.

    I have seen some posts about using ffmpeg to do the conversion but I dont seem to be able to run ffmpeg within python, and when converted to wav the files become around 10 times bigger which is kind of a storage issue.

    Does anyone have any suggestions except for pipelining it ?
