  • FFmpeg RTSP stream to remote MediaMTX server disconnects after a few seconds [closed]

    13 juin, par Rorschy

    I'm new to RTSP and MediaMTX, and I'm trying to live stream my screen using FFmpeg and MediaMTX for a specific use case.

    


    Everything works perfectly when both FFmpeg and MediaMTX run on the same machine.
However, when I move MediaMTX to a remote server, the stream becomes unstable — I can't maintain a connection or view the stream reliably.

    


    Here is the FFmpeg command I'm using from the client machine :

    


    ffmpeg -f gdigrab -framerate 10 -offset_x 0 -offset_y 0 -video_size 1920x1080 -i desktop -f lavfi -i anullsrc -vcodec libx264 -tune zerolatency -g 30 -sc_threshold 0 -preset ultrafast -tune zerolatency -f rtsp rtsp:///live/stream


    


    And here’s the relevant MediaMTX log output on the remote server :

2025/06/12 14:28:54 INF [WebRTC] [session 5f853024] closed: terminated


    


    My questions :

    


      

    1. What could be causing the RTSP stream to disconnect when streaming to a remote MediaMTX server ?

      2. 


    2. Are there any recommended network settings or MediaMTX configuration tweaks to ensure a stable stream over the internet ?

      3. 


    


    Any help or guidance would be greatly appreciated. Thanks !

    


  • Scrolling Effect of an Image using FFmpeg [closed]

    5 juin, par neeebzz

    I want to create an mp4 video of 40 seconds where an image just floats from top to bottom and vice versa.

    


    I am using the following ffmpeg command :

    


    ffmpeg 
    -loop 1 
    -t 40 
    -i ./input.jpg 
    -filter_complex [0]scale=800:-1[s0];[s0]crop=h=450:w=800:x=0:y=(ih-450)*(3*pow(t/40.241\,2) - 2*pow(t/40\,3))[s1];[s1]scale=800:400[s2] 
    -map [s2] 
    -pix_fmt yuv420p 
    -preset medium 
    -r 30 
    -vcodec libx264 
    ./output.mp4 -y


    


    The animation is working as expected however the motion is very jerky. How can I smooth it out ?

    


    Ffmpeg version :

  • avutil : Fix linking x86 asm constants with Clang in MSVC mode

    12 juin, par Martin Storsjö
    avutil : Fix linking x86 asm constants with Clang in MSVC mode

    This fixes building with Clang in MSVC mode, for x86, which was
    
broken in 6e49b8699657b808b7dc80033f2c3f2d0e029fa3 (in Nov 2024) ;
    
previously it failed with undefined symbols for the constants
    
defined with DECLARE_ASM_CONST, accessed via inline assembly.
    

    Before 57861911a34e1c33796be97f2b2f44e05fffd647, there was an
    
    #elif defined(__GNUC__) || defined(__clang__)
    
case before the
    
    #elif defined(_MSC_VER)
    
case for defining DECLARE_ASM_CONST, which included av_used.
    
(This case included the explicit "defined(__clang__)" since
    
f637046d3134a331e4b5a7243ac3dfb92735b8a5.)
    

    After 57861911a34e1c33796be97f2b2f44e05fffd647, it used the
    
generic definition of DECLARE_ASM_CONST that also included
    
av_used - which also worked for Clang in MSVC mode. But after
    
6e49b8699657b808b7dc80033f2c3f2d0e029fa3, Clang in MSVC mode
    
ended up using the MSVC specific variant which lacked the
    
av_used declaration, causing linker errors due to undefined
    
symbols.
