  • Could not find com.arthenica:ffmpeg-kit-full:6.0-2

    I started receiving this message when I build my project

    This is my libs.version.toml

    


    ffmpeg = "6.0-2"
arthenica-ffmpeg-full = {  group = "com.arthenica", name = "ffmpeg-kit-full", version.ref = "ffmpeg" }


    


    AFAICS in the project's github page, it will not be maintained anymore
ffmpeg-kit is archived on April 21, 2025

    


    In the short term, do you know any other repository that still servers this dependency ?

    


    On the other hand, do you know any other project to replace Arthenica ffmpeg-kit-full dependency ?

    


    Thank you very much

    


  • ffmpeg Non monotonous DTS, Previous DTS is always the same, audio microphone streaming [closed]

    5 février, par adrien gonzalez

    I'm using ffmpeg to stream audio from a microphone using rtp. I'm on Raspberry and use an external sound card (HifiBerry DAC + ADC Pro).
My goal is to stream audio with the lowest latency possible to others Raspberry reading this audio with ffplay. I try not to compress the audio flux and leave it untouched as wav 48000 Hz.
I encounter often some Non Monotonous DTS errors. When this happens I have a latency of hundred of milliseconds adding itself.
I tried to add the +igndts flag but it is not changing anything. Also tried +genpts flag.

    


    What is weird is that the previous DTS is always the same (201165 is the example below) and does not seems to change.
I looked on forums for answers but I'm unable to find one.

    


    Here is my bash command :

    


    ffmpeg -guess_layout_max 0 -re -f alsa -i hw -acodec pcm_s16le -ac 1 -payload_type 10 -f rtp rtp://192.168.1.152:5003

    


    And the result from the terminal :

    I tried to add the +igndts flag but it is not changing anything. Also tried +genpts flag. I expected the DTS to restore itself but I still have the same issue
