    16 février 2017, par tiras muturi

    i run this command to be able to stream a udp live stream to a http live stream that is playable using a mobile application that am building.
    its just a stream with audio streams only.

    i really want a way i can be able to map every input stream to have an output stream that can be accessed separately from the other like maybe if i need the first stream maybe i will just

    ffplay http://localhost:8090/feed1.ffm

    and if i need the 7th stream i will just

    ffplay http://localhost:8090/feed7.ffm

    Please can someone help me crack this issue. FFmpeg dont have complex examples for my current situation.

    this is my header information

  • Concat a video with itself, but in reverse, using ffmpeg

    15 février 2017, par Vitam

    I was able to reverse with :

    ffmpeg -i input.mp4 -vf reverse output_reversed.mp4

    And I can concat with :

    ffmpeg -i input.mp4 -i input.mp4 -filter_complex "[0:0] [0:1] [1:0] [1:1] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" output.mp4

    But can I concat with a reverse version of the video, with a single command ?

    What I am trying to achieve is a ping pong effect, where the video plays once, then plays backwards right after.

    Thanks !

  • Demultiplex UDP live stream to multiple single live stream outputs using FFMPEG & FFSERVE

    17 février 2017, par tiras muturi

    i have a problem with ffmpeg. i have an input live stream that has 8 inputs and i want to use ffmpeg to convert it from udp live steram to tcp livestream and then extract each of the 8 input stream differently.

    i have been reading about the ffmpeg documentation at they havent provided a clear way of solving my problem.

    am running
