  • FFmpeg : How to generate a .mp4 with h.265 Codec ?

    5 mai 2014, par skull3r7

    I want to encode a video file to H.265. The last version of ffmpeg should be support H.265 (Source).

    However, I could not find any information about the exact command.

    I do not know, which library I should indicate after -vcodec.

    EDIT : I use the lastest Zeranoe FFmpeg Build (git-c78a416 (2013-10-26)).

  • FFMPEG enocde flv with alpha channel

    25 octobre 2013, par tree

    I'm trying to encode a video (mov) to an flv with alpha channel in FFMPEG but I can't seem to either

    1. find a codec that is supported
    2. find one that actually maintains the alpha

    Does anyone know how to set that up ?

    Thanks,

    ffmpeg -i abc_btr_1280x800_Takeover.mov -vcodec flv -pix_fmt yuv444p -s 1280x800 test4.flv

    here is the report...
