    25 juillet 2022, par kuldeep chopra

    I am streaming to YouTube and Facebook using ffmpeg , also writing data into disk (recording).

    


    it's working fine on Facebook and recording but on YouTube it's giving warning that is

    


    Please check the video resolution. The current resolution is (65535x65535), which is not optimal.

    


    and output on YouTube is also 1:1 aspect ratio due to the above resolution.

    


    I am using tee mux in ffmpeg Command.

    


    ffmpeg -f dshow -framerate 30 -i video="Integrated Webcam":audio="Microphone Array (Intel® Smart Sound Technology (Intel® SST))" -s 1920x1080 -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -crf 28 -pix_fmt yuv420p -c:a aac -strict -2 -ac 2 -b:a 128k -t 4 -map 0 -f tee "[f=ismv]pipe:1 | [f=flv]rtmps ://youtube | [f=flv]facebook"

    


  • Live stream videos on YouTube with ffmpeg ?

    30 janvier 2021, par Manuservus

    What the program should do :

    


    It should download a video from an URL.

    


    Then put the video into a streaming interface (on the right side there should be the live chat from YouTube, in the middle, there should be the downloaded video).

    


    Next stream it live to YouTube.

    


    The process should repeat endless times.

    


    Download video from URL —> Stream it live to YouTube in a streaming interface -> repeat the whole process.

    


    Is this even possible in Python ? If yes how ?

    


    I would appreciate any help !

    


    PS : The stream should run smoothly without a break. That means : As soon as a video is finished, the next comes straight away.

    


  • Which library does Youtube use to process videos on their server ?

    25 janvier 2020, par Ali Raza

    I want to know which library/component does Youtube use to process videos amazingly fast on their server ? I am using FFMpeg to process my video right now but it takes much time to process and create different qualities using bitrate.

    Are there any better alternatives to FFMpeg that can process videos faster like youtube ?
