  • ffmpeg : simple RTMP streaming over LAN

    30 mars 2013, par sajad

    I am trying to launch up a rtmp transcoder server using ffmpeg ; that receives udp MPEG-TS streams as input, transcodes it ; and generates an rtmp output to a URL, that can be accessed by users to receive and play the rtmp stream. All these are expected to be performed in a LAN and the output be accessed by all users.

    1) First I don't know where the URL should point to. Is it enought to specify the IP of the system and some optional port ? Is it neccessary that a program should be listening on that port ?

    2) How I can play the stream on the URL ?

    I use a linux ubuntu machine whith IP=10.1.1.229 and I want to transcode multicast stream on this URL : udp://@224.10.1.1:2001.

    here is the command used to transcode input stream and generate rtmp url "rtmp ://10.1.1.229:2020".

    ffmpeg -y -f mpegts -i "udp://@224.10.1.1:2001" -re -vcodec libx264 -maxrate 700k -r 25 -s 640x360 -deinterlace -acodec libfaac -ab 64k -ac 1 -ar 44100 -f flv "rtmp://10.1.1.229:2020"

    and here is the command by which I am trying to play rtmp stream :

    ffplay rtmp://10.1.1.229:2020

    Any guidance would be helpfull. Thank you.

  • What encoders/decoders/muxers/demuxers/parsers/filters do I need to enable in FFMpeg for converting an mp4 video to a gif ?

    21 juin 2020, par kostik

    I am building FFmpeg with custom options to reduce the final size of apk file on android. I want just convert a mp4 file to a gif.
Following is my options specified

    


     --disable-everything
 --enable-decoder=mpeg4,mpegvideo,aac,gif,h264
 --enable-parser=aac,mpeg4video,mpegaudio,mpegvideo,gif,h264
 --enable-demuxer=mpegvideo,aac,mov,gif,h264
 --enable-muxer=mp4,gif,mov,h264
 --enable-protocol=file
 --enable-encoder=mpeg4,mov,gif,h264
 --enable-filter=scale,fps,copy,palettegen,vflip,paletteuse,crop


    


    What other options do i need to add to successfully run this command ?

    


    ffmpeg -y -i input.mp4 -vf "fps=15,scale=320:-1:flags=lanczos" -pix_fmt rgb24 output.gif


    


    or this command

    


    ffmpeg -y -i input.mp4 output.gif


    


    After I added module into Android Studio I run FFmpeg command.
Iam getting this error :
