• Broadcasting video from the camera to YouTube

  17 octobre 2022, par vernise

  I want to stream video on YouTube. But there are a lot of restrictions. Firstly, I want to do it via an intermediate server. If there is no connection, the broadcast will not complete. Instead, an error will be displayed on the broadcast. This is due to the fact that the camera is close to the battle line. A blackout is not an uncommon occurrence. Also due to the limitations of YouTube (maximum 12 hours of broadcasting time to save), the broadcast has to start twice a day. I tried to implement transmission via FFmpeg and UDP to an intermediary server (I'm using a simple webcam), but the latency at this stage is more than 30 seconds. Any suggestions would be appreciated.

  


• FFMPEG stream MPTS file with all the Metadata to output device (get multiple services at the output)

  24 juillet 2024, par the_man

  The help is needed...

  


  I need to correctly MUX the UDP stream (MPEG Transport Streams) from the dvb app with multiple services (TV Channels) inside and stream it to my modulator device.
All the metadata information should be present in the output file :

  


  

  • Program 10352

  


  • service_name : MDR Sachsen HD

  


  • Stream #0:3[0x67](deu) :... (visual impaired) (descriptions)

  


  • Stream #0:5[0x69](deu) : Subtitle : dvb_teletext

  


  • ...

  


  


  For simplicity, we may write a stream to a file. It should work almost the same way.

  


  Here is an Input :

  At the output, I need to get these two TV services as is to be visible on the TV set, or VLC etc.

  


  My command so far :
case #1

  


  ffmpeg -i udp://192.168.0.20:1234 -buffer_size 5000k -mpegts_flags +resend_headers\
 -metadata service_name="MDR Sachsen HD" -map 0:1 -map 0:2 -metadata language="deu"\
 -metadata service_name="hr-fernsehen HD" -map 0:10 -map 0:12 -metadata language="deu"\
 -c copy -muxrate 31668449 -mpegts_flags +resend_headers -f mpegts - | dd bs=64k of=/dev/dvb/adapter0/mod0


  


  case #2

  


  ffmpeg -i udp://192.168.0.20:1234 -buffer_size 5000k \
-map 0:p:10352 -map 0:p:10355 \
-c copy -muxrate 31668449 -mpegts_service_id 10352 -metadata service_name="MDR Sachsen HD" \

-mpegts_flags +resend_headers -f mpegts - | dd bs=64k of=/dev/dvb/adapter0/mod0


  


  Whatever i try, i get only one TV service at the output :

• FFMpeg - PhantomJS to Youtube Live

  7 février 2021, par Victor P.

  I'm trying to stream a webpage captured with PhantomJS to Youtube using FMMpeg.
This is the command I use :

  



  xvfb-run phantomjs --web-security=no render.js | ffmpeg -threads 0 -y -v verbose -c:v png -r 30 -f image2pipe -i - -f lavfi -i anullsrc -strict -2 -acodec aac -ac 1 -ar 44100 -b:a 128k -c:v libx264 -s 1280x720 -pix_fmt yuv420p -f flv "rtmp://a.rtmp.youtube.com/live2/key";


  



  And the render.js code :
http://pastebin.com/raw/X9gv8iGH

  



  It looks like it's streaming, but no feed is received by YouTube, and I can't see where the problem is.
