  • Embed a Youtube with a MP4 File as poster

    29 août 2021, par adampl

    I want to embed a youtube video with a 10 second silent looping MP4 file as the poster.

    


    Currently, I am using the Wordpress video shortcode with my MP4 as the poster source, it works on some browsers but not all. Can anyone help ? I would prefer to find a pure HTML solution separate to the wordpress shortcode as I will need to get this to work on other CMSs.

    


    [video src="https://www.youtube.com/watch?v=[videoID]" poster=<video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">&#xA;  <source src="/wp-content-directory/intro.mp4" type="video/mp4">&#xA;</source></video>]&#xA;

    &#xA;

    What i have found is to get a looping MP4 work on all browsers, I have to use this tag with the autoplay loop muted and playsinline

    &#xA;

    <video autoplay="autoplay" loop="loop" muted="muted" playsinline="playsinline">&#xA;<source src="/directory/intro.mp4" type="video/mp4">&#xA;</source></video>&#xA;

  • Stream to youtube using Hardware Encoding

    28 août 2021, par Renan F.

    I'm currently streaming to youtube using NVIDIA hardware encoding to reduce the load on the CPU, with this code :

    &#xA;

    ffmpeg -framerate 30 -f gdigrab -i desktop -f lavfi -i anullsrc -c:v h264_nvenc -f flv "rtmp://a.rtmp.youtube.com/live2/KEY"&#xA;

    &#xA;

    My screen resolution is 2560x1080, but this is the result i get in youtube :&#xA;enter image description here

    &#xA;

    There are huge empty spaces on both sides, and the resolution is not so good, even selecting "HD" on youtube.

    &#xA;

    I tried to specify in the last parameter before flv,&#xA;-s 2560x1080 but I could not see any difference.

    &#xA;

    Also would like to ask if someone knows what -qp 0 does, I could not find it in the documentation, it does appear here :

    &#xA;

    https://trac.ffmpeg.org/wiki/Capture/Desktop

    &#xA;

    Under hardware encoding.

    &#xA;

    Looking for any advice, taking in mind I'm trying to reduce the CPU usage and keep a normal/good resolution.

  • How can I improve the frame rate of my Raspberry Pi to YouTube stream ?

    2 août 2021, par RDowns

    I am using a Raspberry Pi 4 2GB to live stream to YouTube.

    &#xA;

    The performance is pretty poor at the moment as I am trying to go through terminal and I feel the setting's are not correct. Performance is OK however if I go directly through YouTube studio and use the 'Webcam' option instead of 'Stream'.

    &#xA;

    These are the settings that I am currently using :

    &#xA;

    raspivid -o - -t 0 -vf -hf -fps 30 -b 6000000 | ffmpeg -threads 0 -f v4l2 -i /dev/video0 -ar 44100 -ac 2 -acodec pcm_s16le -f s16le -ac 2 -i /dev/zero -acodec aac -ab 128k -strict experimental -s 640x480 -b 6000000 -aspect 16:9 -vcodec h264_omx -vb 820k -pix_fmt yuv420p -g 60 -r 30 -f

    &#xA;

    What options can I change in this command to improve the frame rate and give better performance ?

    &#xA;
