  • ffmpeg convert rtmp audio/video stream to icecast2 audio/video stream

    17 avril 2023, par Solomon Thatcher

    I've been using this command to convert my public rtmp audio/video stream to a local mp3 audio icecast2 stream, but I have been unable to do the same for both video and audio.

    


    [Audio Only] (This works fine)
    
ffmpeg -re -i rtmp://162.142.xx.xxx:xxx/stream -vn -codec:a libmp3lame -b:a 128k -f mp3 -content_type audio/mpeg icecast://source:password@192.168.1.xxx:80/live

    


    I've tried to re-write in order to support video, but I keep hitting dead ends

    


    [Audio & Video Attempt] (this does not work)
    
ffmpeg -re -i rtmp://162.142.xx.xxx:xxx/stream -codec:v -f mpeg4 -b:v -f mpeg4 -content_type video/mpeg4 icecast://source:password@192.168.1.xxx:80/live

    


    When I run this command, it gives me the error below asking for a suitable format.

    


    $ ffmpeg -re -i rtmp://162.142.xx.xxx:xxx/stream -codec:v -f mpeg4 -b:v -f mpeg4 -content_type video/mpeg4 icecast://source:password@192.168.1.xxx:80/live

    I am positive that icecast2 can support video streams, however on the few occasions that I was able to actively stream successfully to it, it only showed an empty video embed.

    


    I've re-written the command for AV multiple times while referencing ffmpeg documentation, however my above attempt seems to be the closest (concept-wise) that I have gotten.

    


    What flags/formatting might I be missing which are causing the stream not to work ?

    


  • FFMpeg mixing audio to video creates silent video after audio is added,

    25 mars 2018, par 1234567

    mixing audio to video creates silent video after audio is added, using FFMpeg

    this is the command I am using

    "-y","-i",j,"-filter_complex","amovie="+audio+":loop=999,asetpts=N/SR/TB,atrim=0:18,adelay=50000|50000,aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=1.5[a1];[0:a]aformat=sample_fmts=fltp:sample_rates=44100:channel_layouts=stereo,volume=2.0[a2];[a1][a2]amerge,pan=stereo:c0code>

    I have a video which is 2 mins 7 seconds ling, I want to ’mix’ audio to a part starting from 50 seconds to 68 seconds

    What i want is to keep original sound from video and mix audio to existing sound of video(not over write) it, (keep old video sound and new audio in video)

    what happens is till 50 seconds video has its own sound, from 50 -68 the audio over writes the video sound and from then till end it is silent

    what i want is video to have its sound through out the video and mix from 50 -68 seconds the audio to it

    this graphic can explain a bit of what i want and what i am getting

    What i want enter image description here
    what i am gettingenter image description here
    another problem that I am facing is
    if i try this on a silent video (video with no sound at all) this code fails this is the error that I am getting
