• VPS as video relay server using ffmpeg and ffserver ?

  15 juillet 2016, par Luke E

  I’m working on a project where I need to send a video stream from a laptop through a router I don’t have control of to an Android phone on another network I don’t have control of. The project also involves sending a stream of sensor data the opposite direction, for which I’m using a VPS and TCP hole punching quite successfully.

  So, I thought to myself, why not just stream the video from ffmpeg on my laptop to ffmpeg on the VPS, and then relay that via ffserver to my android phone ? That’s what I’ve been trying to do for a good while now, but haven’t had much luck. The stream is recognized by the server but when putting it out over ffserver I get errors. Here is my ffserver.conf :

  HTTPPort 9000
  
  HTTPBindAddress 
  
  RTSPPort 5454
  
  RTSPBindAddress 
  
  
  
  <feed>
  
  File /tmp/feed1.ffm
  
  FileMaxSize 50M
  
  </feed>
  
  
  
  <stream>
  
  Feed feed1.ffm
  
  Format rtp
  
  VideoSize 960x540
  
  VideoBufferSize 0
  
  VideoFrameRate 30
  
  NoAudio
  
  AVOptionVideo flags +global_header
  
  </stream>

  And here’s the command I’m using to take the received stream on the VPS and transmit it to ffserver :

  ./ffmpeg -protocol_whitelist file,udp,rtp -i foo.sdp  -an -c copy -f rtp rtsp://:5454/feed1.ffm

  When doing this command, I get the error "rtsp ://:5454/feed1.ffm : Protocol not found"

  Any advice ?

  I also thought about doing this with netcat and just and trying to forward all data received on the VPS at a certain port 1234 to any client connected to say port 1235, but this appears to be much more difficult than I thought.

  Thanks again for any help, and hopefully this problem is interesting to others as well.

• Split into equal parts and convert many mp4 videos using ffmpeg

  9 septembre 2015, par bobafetta

  I have a ton of videos I need to convert from mp4 to wmv using ffmpeg and break up each file into 10 minute segments, but I am a total cmd scripting newb (in fact, I am a scripting newb :)

  After spending six hours trying to find an answer, I thought I would bring it to you guys.

  The code I have is working a little bit, but I need to be able to read data coming from the command line and send it back into the script for evaluation. I am not sure what code ffmpeg will spit out when it is done processing a video file (when the timestamp reaches an end), but this FOR loop just keeps on trying to create new file segments even though the video is over. This is what I saw when it tried to create a new file, so I think it might work to search for this :

  frame= 0 fps=0.0 q=0.0 Lsize= 1kB time=00:00:00.00 bitrate=N/A

  This is the code I have come up with so far (Don’t laugh :)

  @echo off
  
  setlocal ENABLEEXTENSIONS
  
  setlocal ENABLEDELAYEDEXPANSION
  
  
  
  for %%a in ("*.mp4") do (
  
  set hour=00
  
  
  
  for /L %%i IN (1,1,10) do (
  
  :Beginning
  
      set /a start=%%i-1
  
          set end=%%i
  
          if !start! lss 10 set start=!start!0
  
          if !end! lss 10 set end=!end!0
  
          ffmpeg -ss !hour!:!start!:00 -i "%%a" -b:v 1500k -vcodec msmpeg4 -acodec wmav2 -t !hour!:!end!:00 "Converted\%%~na-!hour!-!start!-!end!.wmv"
  
          if end==60 CALL :Increment
  
      )   
  
  )
  
  
  
  :Increment
  
      set /a !hour!+1
  
      set %%i=1
  
      GOTO :Beginning
  
  pause

  Based on reading this thread was thinking something like this might go in the code, but not sure what to do with it :

  set "dosstring=%*"
  
  
  
  echo.!dosstring!|findstr /C:"frame=    0 fps=0.0 q=0.0 Lsize=       1kB time=00:00:00.00 bitrate=N/A" >nul 2>&1

  Thanks so much for you help !
