• FFMpeg with PHP-7.0 on Ubuntu

  25 octobre 2018, par Gabriel Bueno Lemes da Silva

  I have a NGINX server with PHP-7.0 and I would like to install the ffmpeg-php extension. I’ve been trying for a few days now and in many ways.

  The method that worked so far was compiling ffmpeg (https://ffmpeg.org/releases/ffmpeg-4.0.2.tar.bz2) manually, but when trying to compile ffmpeg-php (https: // sourceforge. net / projects / ffmpeg-php / files / ffmpeg-php / 0.6.0 / ffmpeg-php-0.6.0.tbz2 / download) I am encountering the following error message :

• ffmpeg nvenc_h264 streaming uhd2160 rawvideo. Youtube buffering

  23 janvier 2019, par Alex Deroza

  I use this batch file for starting my stream :

  Stream on YouTube starts fine, and plays with good quality. But stream stops after when "Buffer Health" emptied. And in this situation Youtube says that "Video output low", "YouTube is not receiving enough video to maintain smooth streaming. As such, viewers will experience buffering."

  I can’t understand why it happens. Because I’ve a good ISP, and over 30 mbps inet to YT services within 90ms latency to them.

  YouTube is not receiving enough video to maintain smooth streaming. As
  such, viewers will experience buffering.

  Your encoder is sending data faster than realtime (multipleseconds of
  video each second). You must rate limit your livevideo upload to
  approximately 1 second of video each second.

  The stream’s current bitrate (5730.00 Kbps) is lower than the
  recommended bitrate. We recommend that you use a stream bitrate of
  4500 Kbps.

• How do I correct the ffmpeg to stream my mp4 ?

  16 avril 2019, par Alex Serban

  I’m trying to setup a live stream from my raspberry pi to youtube using ffmpeg, but the stream fails to start

  I’ve tried first streaming an MP4 file I’ve captured using raspivid to figure out how ffmpeg works. I’ve captured a 10 mins video, at 426x240, bitrate 222kbps, 25 frames/sec and tried streaming.

  ffmpeg -re -i "video4-10min.mp4"  -acodec libmp3lame -ar 44100 -b:a 128k -pix_fmt yuv420p -profile:v baseline -s 426x240 -bufsize 2048k -vb 222k -maxrate 800k -deinterlace -vcodec libx264 -preset medium -g 30 -r 30 -f flv "rtmp://a.rtmp.youtube.com/live2/[my-stream-key]"

  Stream looks like it’s starting, the health prompt says : "4:48 PM Good Stream is healthy / Stream health is excellent."
  but in a few secs goes to : "4:48 PM No data No active stream",
  even though the ffmpeg looks like it’s streaming accurately : "frame= 1061 fps= 25 q=-1.0 Lsize=    1205kB time=00:00:42.40 bitrate= 232.9kbits/s speed=0.994x"
