• Setting up a server to redistribute a webcam stream

  22 janvier 2013, par Martin Taleski

  I am trying to set up a streaming server that will receive a RTP stream and redistribute it.

  I am able to create the stream with :

  ffmpeg -f video4linux2 -i /dev/video0 -vcodec mpeg2video -r 25 -pix_fmt yuv420p -me_method epzs -b 2600k -bt 256k -f rtp rtp://myserver:8090/

  I see the UDP packets coming to my server, but I was not able to set up a feed and a stream with ffserver. I can also view the stream though VLC if I change the destination IP of the server with my local IP.

  I am now considering writing a daemon in python or perl or C, that will read the UDP packets coming on port 8090 on the server, and distribute them on another port. Not sure if this is a great idea, but can not find any other clues...

  Any clues how to make this happen ?

• How do I install stream-m on my vps server using putty for windows

  19 décembre 2014, par They Went Viral

  when i logged into my vps server using the plesk control panel i see httpdocs in the root when using putty i entered an ls command and i only see

  @vps : # ls
  ffmpeg parallels parallels_installer plesk-installer.sh univac.webm

  wonder why this is why dont i see the same files as in te control panel ??!

  the problem is i am trying to run this https://github.com/vbence/stream-m on the server
  the read me says

  RUNNING THE SERVER

  java -jar stream-m.jar

  Before running the server you should edit the sample config file (change password and choose a stream name). So you will end up with something like :

  java -jar stream-m.jar server.properties

  but im getting an error that says

  @vps : # java -jar stream-m.jar server.properties
  Error : Unable to access jarfile stream-m.jar

  Now i do have ffmpeg installed as per putty but when logged into the control panel i don’t see that either what am i doing wrong ?

• Muxing files with different run times

  16 novembre 2019, par Dhruv Kanojia

  I’ve got a few files I want to mux.
  File 1 : MP4 File with runtime of 23 Minutes 45 Seconds
  File 2 : MP4 File with runtime of 23 Minutes 39 Seconds
  File 3 : Subtitle File
  File 4 : Subtitle File
  File 5 : Subtitle File
  File 6 : Subtitle File
  File 7 : Subtitle File
  File 8 : Subtitle File
  File 9 : Subtitle File

  I’m trying to mux these files. Now, since there’s a runtime difference, I’m getting weird errors like :

  [matroska @ 0x55e029fbd1a0] Only audio, video, and subtitles are supported for Matroska.
  
  av_interleaved_write_frame(): Invalid argument
  
  Error writing trailer of /root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [Dual Audio].mkv: Invalid argument

  I can mux files with same run time just fine... but, I’m stuck on this one. Can someone help me out here.

  The command I’m using :

  ffmpeg -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [enUS].mp4" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [jaJP].mp4" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [enUS] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [itIT] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [esLA] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [frFR] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [esES] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [deDE] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [ruRU] .ass" -i "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [ptBR] .ass" -map 1 -map 2 -map 3 -map 4 -map 5 -map 6 -map 7 -map 8  -map 0:v -map 0:a -map 1:a -c copy -metadata:s:a:0 title="English Audio" -metadata:s:a:1 title="Japanese Audio" -metadata:s:a:0 language=eng -metadata:s:a:1 language=jpn -metadata:s:s:0 title="English (US) Subtitle" -metadata:s:s:1 title="Italian Subtitle" -metadata:s:s:2 title="Spanish (Latin America) Subtitle" -metadata:s:s:3 title="French Subtitle" -metadata:s:s:4 title="Spanish Subtitle" -metadata:s:s:5 title="Deutsch Subtitle" -metadata:s:s:6 title="Russian Subtitle" -metadata:s:s:7 title="Portuguese Subtitle"  "/root/my_dls/Output/My Vid/1/en-us/1080p/My Video - 1 [Dual Audio].mkv"
