  • YouTube Live not working with FFMPEG

    29 septembre 2020, par Benedikt Neumayr

    EDIT : It already works. My new router seems to block rtmp traffic. I edited the firewall config and now it works !
    
I'm trying to stream to YouTube with ffmpeg with the following command :

    



    ffmpeg -f alsa -ac 2 -i hw:0,0 -f v4l2 -s 1280x720 -r 10 -i /dev/video0 -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -strict experimental -r 25 -g 20 -b:v 2500k -codec:a libmp3lame -ar 44100 -b:a 11025 -bufsize 512k -f flv rtmp://a.rtmp.youtube.com/live2/45ee-qka9-0djm-796z   


    



    My ffmpeg version 2.8.11 on Linux Mint 18.2 then says :

    



    Input #0, alsa, from 'hw:0,0':
  Duration: N/A, start: 1511081240.166016, bitrate: 1536 kb/s
    Stream #0:0: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 kb/s 
[video4linux2,v4l2 @ 0xacba60] The driver changed the time per frame from 1/10 to 2/15
Input #1, video4linux2,v4l2, from '/dev/video0':
  Duration: N/A, start: 5907.755626, bitrate: 110592 kb/s
    Stream #1:0: Video: rawvideo (YUY2 / 0x32595559), yuyv422, 1280x720, 110592 kb/s, 7.50 fps, 7.50 tbr, 1000k tbn, 1000k tbc


    



    After that it does nothing for about 3 minutes,then it finally returns the following error :

    



    RTMP_Connect0, failed to connect socket. 110 (Connection timed out)
rtmp://a.rtmp.youtube.com/live2: Unknown error occurred


    



    I used these instructions :

    



    


  • Livestreaming screencast to Youtube through ffmpeg doesn't show video even though data is received [duplicate]

    15 novembre 2017, par CindyRabbit

    This question already has an answer here :

    I am trying to livestream my Desktop in Ubuntu to Youtube and used this cmd. Youtube livestream showed green bar with "Receiving your data" and Youtube log also showed "Stream healthy", however no video showed up in Youtube player, and after a short while Youtube log said "Stream complete". What’s missing in my cmd ?

    ffmpeg -f x11grab -r 10 -s 1024x720 -i :0.0 -vcodec libx264 -pix_fmt yuv420p -preset ultrafast -g 20 -b:v 2500k -threads 0 -bufsize 512k -f flv rtmp ://a.rtmp.youtube.com/live2/myKey

    BTW, only screencasting doesn’t work for me, streaming a video file works for me.

  • Making youtube-dl download mp3's faster

    12 novembre 2017, par sciencelord

    It takes a long time to download mp3 songs using youtube-dl, and it takes even longer when downloading a bunch of mp3 songs. Is there a way to make it significantly faster ? I don’t mind reducing quality. I’ve been using the command below.

    youtube-dl --extract-audio --audio-format "mp3" --output "%(title)s.%(ext)s" "https://www.youtube.com/watch?v={videoid}

    I also took a look at this post :
    ffmpeg command for faster encoding at a decent bitrate with smaller file size

    But I wasn’t sure how to change the above command using the ffmpeg modifications.

    Thanks !
