  • avformat.lib and VS2013

    27 février 2016, par KevinA

    I’m compiling FFmpeg statically against VS2013 update 5 using —toolchain=msvc

    If I link against avformat.lib i get a bunch of LNK2019 errors.
    I can link make calls against the other libraries(avcodec, swscale, avutil).

    Looking at the errors, it seems to be against all the networking .o’s (tls_schannel.o, networking.o, tcp.o, etc....)

    Here is the output

  • Running Live streaming of local user using ffmpeg at Web plateform

    23 décembre 2019, par Sneha Makwana

    I am using below command to stream my live desktop screen.

    ffmpeg -f x11grab -r 1 -loglevel panic -s `xdpyinfo | grep 'dimensions:'|awk '{print $2}'` -i $DISPLAY -qscale 0 -f mpegts udp://192.168.3.151:1111

    udp ://192.168.3.151:1111 - this is my streaming URL

    I can see live streaming in the parole media player (in Linux platform), but I can’t see this in a cross-network (i.e from windows PC - in the same network)

    Is there any web platform so I can see my streaming from anywhere (either windows or linux) just using unique streaming URL or do I need to change my streaming command or method ?

    Any help is much appreciated

  • Streaming UVC capture device with FFMPEG

    28 février 2021, par raymater

    I would like to stream the audio and video signal from my HDMI UVC Capture device (AVerMedia ExtremeCap UVC) connected to my RPi 4 (its IP is : 192.168.1.15).

    


    So I'm using ffmpeg, my command works but in my other PC, VLC can't play the stream. I see the progress bar searching but nothing, it goes around in circles.

    


    My FFMPEG command (works) : ffmpeg -f v4l2 -i /dev/video0 -f alsa -i hw:1 -c:v h264_omx -profile:v baseline -b:v 16000k -flags:v +global_header -bsf:v dump_extra -acodec aac -b:a 384k -ac 2 -ar 44100 -f rawvideo udp://192.168.1.15:8888

    


    In VLC (network stream) on an other PC in the same network, I'm using this address : udp://192.168.1.15:8888. Doesn't work.

    


    What should be done ?
