  • FFMPEG & YouTube Live - "Bad Video Settings" - Please use a keyframe frequency of four seconds or less

    28 janvier 2020, par John Doe

    Trying to live stream to YouTube and from my perspective, everything seems to be working fine. However YouTube keeps giving me the following message :

    Bad Video Settings

    Please use a keyframe frequency of four seconds or less. Currently, keyframes are not being sent often enough, which will cause buffering. The current keyframe frequency is 8.4 seconds. Note that ingestion errors can cause incorrect GOP (group of pictures) sizes.

    I’ve dug around for hours and so far nothing seems to be making any difference. I added -g 60 and as I didn’t fully understand I also tried adding -g 2 but neither worked. Here is the command I’m currently using :

    ffmpeg -re -f concat -safe 0 -i "concat.txt" -c copy -preset veryfast -maxrate 1200k -bufsize 2400k -framerate 30 -g 60 -f flv rtmp://a.rtmp.youtube.com/live2/XXXX-XXXX-XXXX-XXXX

  • Why my youtube video made with ffmpeg only shows 360P and 1080P on mobile devices but works fine on desktop ?

    1er janvier 2020, par CheeseWithMe

    I am trying to create a video from an image and sound file with ffmpeg.

    This is what I use :

    ffmpeg -y -loop 1 -r 6  -i current_image.png -i current_audio.wav -shortest -c:v libx264 -preset ultrafast -tune stillimage -pix_fmt yuv420p -c:a aac out.mp4

    But uploading this on youtube will display only in 360P and 1080P on mobile devices while on Desktop I have all the resolutions up to 1080P.

    It has the same effect with the command from FFmpeg wiki on enconding from youtube

    ffmpeg -loop 1 -framerate 2 -i input.png -i audio.m4a -c:v libx264 -preset medium -tune stillimage -crf 18 -c:a copy -shortest -pix_fmt yuv420p output.mkv

    I have no idea why is this happening, I could use some guidance.

  • How can I stream video in swift using FFmpeg in real time ?

    13 novembre 2019, par rIn

    I want to make a real time video streaming app but I’m new to Swift and live streaming..

    Video input captured by AVCaptureSession is from iPhone and I want to encode the input from MPEG-4 to MPEG-2.
    I will use FFmpeg library to encode the video input in swift.

    Here’s my questions.

    1. I don’t know how to deliver video data to FFmpeg functions. Actually I’m not certain that I have to use FFmpeg library to encode video data from MPEG-4 to MPEG-2 transport stream. Is there any API that can encode video data in Swift by Apple ?

    2. How can I deal with video data from AVCaptureSession ? Are there frames or h.264 video in CMSampleBuffer ? I want to know what type of data is in CMSampleBuffer.

    I’m struggling to solve this problem. Please let me know anything if you have some experiences about this kind of project. Any ideas or advice for a better approach are welcome.
