• ffmpeg streaming to rtmp at 30fps

  19 janvier 2018, par user6326558

  I am trying to stream my desktop to facebook rtmp server using screen-capture-recorder :

   -re  -rtbufsize 256M -f dshow -i audio="Mikrofon (Realtek Audio)" 
  
  -rtbufsize 256M -f dshow -i audio="virtual-audio-capturer"  
  
  -rtbufsize 1024M -f dshow -i video=screen-capture-recorder -r 30  
  
  -filter:v scale=1280:720 -c:v  h264_nvenc -pix_fmt yuv420p -preset fast 
  
  -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k -ar 44100 
  
  -f flv rtmp://live-api.facebook.com:80/rtmp/..............

  I am using h264_nvenc codec for gpu acceleration, but I can stream at only 12-18 fps. However, when I stream into a file :

   -re  -rtbufsize 256M -f dshow -i audio="Mikrofon (Realtek Audio)" 
  
  -rtbufsize 256M -f dshow -i audio="virtual-audio-capturer"  
  
  -rtbufsize 1024M -f dshow -i video=screen-capture-recorder -r 30  
  
  -filter:v scale=1280:720 -c:v  h264_nvenc -pix_fmt yuv420p -preset fast 
  
  -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k -ar 44100 
  
  D:\test.mp4 -y

  I get 30 fps without problem, even when playing game (eg. Call of duty 6, pretty HW draining). Is it also possible to stream to rtmp at 30 fps with my command configuration ? Thank you

  If needed, my ffmpeg build config is :

• ffmpeg rtmp streaming at 30fps

  19 janvier 2018, par user6326558

  I am trying to stream my desktop to facebook rtmp server using screen-capture-recorder :

  ffmpeg -re  -f dshow -i audio="virtual-audio-capturer" -hwaccel cuvid 
  
  -f dshow -i video=screen-capture-recorder  -r 30 -rtbufsize 1024M 
  
  -filter:v scale=480:360 -vcodec libx264 
  
  -pix_fmt yuv420p -preset fast -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k 
  
  -ar 44100 -f flv rtmp://live-api.facebook.com:80/rtmp/..............

  But when I start streaming, it says that fps is only 10 and sometimes it immediatelly on start-up yells following error. Then, when I start to do something on my computer, for example I run a game, I keep getting that warning 20 times per second, and streamed video is 0.5 fps.

  real-time buffer [screen-capture-recorder] [video input] too full or near
  too full (545% of size : 3041280 [rtbufsize parameter]) ! frame dropped !

  When I stream it into file,

  ffmpeg -re  -f dshow -i audio="virtual-audio-capturer" -hwaccel cuvid 
  
  -f dshow -i video=screen-capture-recorder  -r 30 -rtbufsize 1024M 
  
  -filter:v scale=480:360 -vcodec libx264 
  
  -pix_fmt yuv420p -preset fast -b:v 8M -maxrate:v 10M  -c:a aac -b:a 128k 
  
  -ar 44100 D:\test.mp4 -y

  it says streaming is 30 fps, but as soon as I start doing something, for example game, the metioned situation repeats, tens of errors, and 0,5 fps video.

  I tried chanching -rtbufsize from 8 to 2048 megabytes, nothing changed. I tried adding and disablinh hw acceleration, nothing changed. Can anyone tell me, what am I doing wrong ? Thank you

  Solved -rtbufsize 1024M must be before -i. Another thing, I rather used codec h264_nvenc from nvidia for cuda acceleration, now I can stream into file at 30 fps without problems and warnings, even while playing game (Call of duty 6, HW draining). However, when I try to stream to rtmp, I also get no warnings, but I can stream at only 15 fps. Is it also possible to stream to rtmp at 30 fps with my command configuration ?

• Piwik Analytics becomes Matomo to reflect Users’ Privacy Focus

  10 janvier 2018, par Matomo Core Team

  One of the world’s leading analytics software platforms is changing its name. Piwik is the sixth most-used web and mobile analytics computer solution worldwide. It is now changing its name to Matomo.

  The name change comes after 10 years of Piwik building its top analytics software, with great success. It is already used on over one million websites in more than 170 countries. Matomo will build on that success, and focus even more on privacy.

  ‘Privacy has become a huge concern worldwide’, says Matomo’s creator, Matthieu Aubry. ‘Privacy legislation is being developed in Europe, and we will be ahead of the game in being ready for those changes. We’ll grow in line with the law and regulation changes.’

  Matomo will lead the way in openness and transparency for its users. Its new name means honesty in Japanese.
  ‘Matomo will always be free and community-driven, just as Piwik was’, says Matthieu Aubry. ‘We have worked with hundreds of people to create the best open digital analytics solution in the world. We’re committed to giving every user full control of their data.’

  The change of name is appropriate as the Matomo platform moves into a new stage of growth. But for its community, little will obviously change. The same people will still be involved, and users will still get useful data to improve their own website. That data includes who visits their site, what they do there, how long they stay, and what they buy.
  Matomo is an all-in-one analytics solution that gives companies a 360 degree view of their users.

  ‘They can grow their business while still keeping 100% ownership of their data, and being fully compliant with privacy laws’, says Matthieu Aubry. ‘We’re more motivated than ever to building on that, so that Matomo stays ahead of the pack.’

  The platform can be fully customised with hundreds of plug-ins, integrations and configurations.

  Matomo’s updated website and new logo is now available on https://matomo.org.
