  • xuggler- ffmpeg

    17 juin 2012, par user1462351

    I am interested in trying out the Live encoding tutorial with Xuggler : http://wiki.xuggle.com/Live_Encoding_Tutorial. However, this tutorial is written for version 3.4. I am using 5.4, which just comes with a jar file for xuggler. I am using WinXP, 32-bit. When I run ffmpeg -i /invalid/file on cygwin, I get "ffmpeg : command not found". I cannot find the ffmpeg binary as part of the xuggler package. So how I can I execute the ffmeg command with xuggler version 5.4 ?

  • Video made from images using ffmpeg is not seekable in some players

    14 avril 2017, par Satya

    I’m trying to make video from images, used the following command

    ffmpeg -framerate 1/5 -i img%03d.png -c:v libx264 -vf fps=25 -pix_fmt yuv420p out.mp4

    as explained in the link https://trac.ffmpeg.org/wiki/Slideshow. But the problem is in some popular players if I try to seek the video, it plays from the beginning(video restarts from 0:00). How can I make a seeklable video ?

  • ffmpeg Decode Hardware Accelerator concept and NVDEC, DXVA

    12 février 2019, par Hun

    I have video player using DX11, FFMPEG but It has so much CPU usage when H.264 4K 60FPS video play.
    So I try to hardware accelerated decode and search about this.
    But All I can get confused.
    According to this page.

    https://trac.ffmpeg.org/wiki/HWAccelIntro

    I can choose between DXVA2, NVENC.
    But I do not know what is different.

    1. Can you explain the advantages and disadvantages of these ? (pros and cons)

    2. Is there a hardware acceleration method other than these ? ex) hardware

    acceleration of ffmpeg itself. Codeccontext->hwaccel//

    Thanks for reply
