  • FFmpeg - How should I do to convince YouTube that it is receiving "endless" video stream ?

    16 octobre 2017, par K._

    I’m using FFmpeg and Youtube Live Streaming API to live-stream videos to YouTube.

    I made something generates video files continuously,
    and I want to live-stream them to YouTube without any delay.

    To feed them to YouTube’s RTMPT(rtmp ://a.../live2/...) server,
    I tried several things :

    1. Just while:; do ./ffmpeg ... rtmp://...; done.
    2. Piping

    YouTube streamed them continuously, but not seamlessly.
    It showed Buffering icon for about 20 seconds (as if a new YouTube stream gets created and starts to be fed), about 5 seconds before the currently showing video ends and the next video get showed.

    | ...===============(BUFFERING)===== | ...===============(BUFFERING)===== | ...

    It seems that YouTube just stops the stream when it detects the end of a video.
    How should I do to convince YouTube that it is receiving "endless" video stream ?

  • Crackling noise and other audio defects when live streaming (only) on YouTube

    7 août 2020, par almosnow

    I am using ffmpeg to transcode and stream a live video, using rtmp. Everything works fine BUT the audio that comes out on the YouTube end has cracks and pops, like what you would expect to hear when your sound card's buffer is saturated.

    


    What's weird is that I am sending the exact same information to different services, and only YouTube seems to have a problem with it. For this I am using ffmpeg's tee, like this :

    


    ffmpeg -i - -deinterlace -map 0 -flags +global_header 
       -f tee "[f=flv:onfail=ignore]rtmp://twitch/key|[f=flv:onfail=ignore]rtmp://youtube/key|out.flv"'


    


    So, the twitch end sounds great, the output file that I'm rendering also sounds good. Only on YouTube it sounds really bad.

    


    I thought it may be the audio codec, the audio settings I'm using are -c:a aac -b:a 128k -ar 44100 ; but I've tried different things (using an mp3 codec, different bitrates) and it always sounds like that. Also AAC seems to be supported according to their own (YT) guidelines.

    


    What could it be ?
