  • FFmpeg with libx264 skipped many frames during re-encoding

    18 mai 2019, par Igor

    I found a strange problem with FFmpeg 4.1.3 when I re-encode this video file with libx264 and I use bitrate 8000k mode.

    



    ffmpeg -y -i src.mp4 -c:v libx264 -preset slow -b:v 8000k dst.mp4


    



    Source video (28 seconds) shows 3 images.

    



    After re-encoding I see only 2 images and 3rd image is missing. I tested in latest VLC player 3.0.6, MPC-HC, Media player in Windows 10.

    



    If I use crf video encoding instead of bitrate everything is fine.

  • Ghosts after converting video from .mp4 mpeg4 codec to webm

    15 avril 2014, par Kotkot

    I've got problem converting from mp4 to webm.
    I use this ffmpeg command to convert from mp4 to webm

    ffmpeg -i output.mp4 -acodec libvorbis -vcodec libvpx -b:v 3M  -qmax 63 -crf 0 -ac 2 -ar 44100 -r 30  -s 640x640 output.webm

    Result as you can see it on output.webm in some frames contains ghost images of previous frames. How to fix it ?

    I do generate the original movie manually using xuggler and perhaps I can change something
    in the original movie to make conversion work properly.

  • Reduce the latency in live streaming from Android to red5

    5 mars 2014, par user1709752

    I'm trying to find a way to reduce the latency while live streaming from android device to red5 media server.

    I've used this, this and this(Only audio) library to create my own test applications.
    and I've used also an app found on play store.

    The latency is always not less than 2-3 seconds.
    Any suggestions how to reduce it ?
    Has anybody succeed in this ?

    I'm streaming within a LAN to the "oflaDemo" red5 demo app and viewing the stream with the "Publisher" red5 demo app.
