    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

  • Android FFMPEG + SDL2 Full screen issue (Video)

    15 janvier 2018, par byungkyu

    I make video player, use ffmpeg, SDL2.
    when I compile ffmpeg, I add —disable-filters, and I scale video using SDL.

    VideoPicture *vp;
    

    
vp = &is->pictq[is->pictq_windex];
    
Uint32 flags(SDL_GetWindowFlags(vp->screen));
    
flags ^= SDL_WINDOW_FULLSCREEN_DESKTOP;
    
SDL_SetWindowFullscreen(vp->screen, flags);
    
int w = 640, h = 480; // TODO: UPDATE ME! ;)
    
if ((flags & SDL_WINDOW_FULLSCREEN_DESKTOP) != 0)
    
{
    
    LOGI("toggleFullscreen 1189");
    
    SDL_SetHint(SDL_HINT_RENDER_LOGICAL_SIZE_MODE, "overscan");
    
    SDL_SetHint(SDL_HINT_RENDER_SCALE_QUALITY, "linear");
    
    SDL_RenderSetLogicalSize(vp->renderer, w, h);
    
}
    
else
    
{
    
    LOGI("toggleFullscreen 1195");
    
    SDL_SetWindowSize(vp->screen, w, h);
    
}

    but this code show black bar, upper side and down side.
    how to make full screen, no black, and expand video height ?

  • How to get rid of errors "jitter buffer full" in ffmpeg ?

    31 janvier 2021, par jidckii

    How to get rid of errors jitter buffer full ?
    
I use ffmpeg from one of the latest snapshots.
    
ffmpeg version N-90078-gf611fef Copyright (c) 2000-2018 the FFmpeg developers

    



    The problem is that from the camera on rtsp there is such a stream :
    
http://ibb.co/fmckCc
    
It is not possible to fix this from the camera side.

    



    I accept it like this :

    



    ffmpeg \
-strict experimental \
-fflags + genpts \
-fflags + latm \
-seek2any 1 \
-avoid_negative_ts + make_zero \
-max_delay 5000000 \
-rtsp_transport udp \
-i rtsp: // admin: @ 192.168.87.21: 554/0? .sdp \
-map 0 \
-r 15 \
-c: v copy \
-an \
-f mpegts udp: //239.0.0.1: 1234? ttl = 1? pkt_size = 1316


    



    I later start to get errors from time to time

    



    [rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 1 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 1 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 2 packets
[rtsp @ 0x154d180] jitter buffer full
[rtsp @ 0x154d180] RTP: missed 4 packets


    



    because of this the picture crumbles.

    



    I increased the udp buffer in the linux kernel settings :

    



    net.core.rmem_max = 16777216
net.core.wmem_max = 16777216
net.ipv4.udp_mem = 8388608 12582912 16777216
net.ipv4.tcp_rmem = 4096 87380 8388608
net.ipv4.tcp_wmem = 4096 65536 8388608


    



    It did not solve my problem.
    
Tell me, how can you deal with such errors ?

    


  • Revision d928b34efe : Allow full RD TX size search for GF/ALT at speed 2 For speed 3 and above, such

    21 avril 2014, par Yaowu Xu

    Changed Paths :
     Modify /vp9/encoder/vp9_speed_features.c



    Allow full RD TX size search for GF/ALT at speed 2

    For speed 3 and above, such search is only allowed at speed 3.
    The change helped cif and stdhd set by 1.2% and .7% in compression,
    but increased the encoding time by around 5%.
