• Stream from MP4 file over RTSP with ffserver

  25 octobre 2019, par sirlion

  I’m trying to stream a mp4 file over RTSP using ffserver with no luck so far. I just want to stream directly from the file, without feeding from ffmpeg (no transcoding involved). But I’ve made it work with mpg video.

  Here is my ffserver config file :

  Port 8090
  
  BindAddress 0.0.0.0
  
  MaxHTTPConnections 2000
  
  MaxClients 1000
  
  MaxBandwidth 500000
  
  CustomLog -
  
  NoDaemon
  
  
  
  RTSPPort 7654
  
  RTSPBindAddress 0.0.0.0
  
  
  
  <stream>
  
      Format rtp
  
      File "/home/g/video_streaming/sample3-mpeg2.mpg"
  
  </stream>
  
  <stream>
  
      Format rtp
  
      File "/home/g/video.mp4"
  
  </stream>

  When I launch ffserver, everything seems fine based on the log output :

  $ ./dev/ffmpeg/ffserver -f ffserver-sample.conf

  Finally, if I run ffplay in order to test the server, everything works fine for the mpg file, but not for the mp4 :

  I don’t really know what I could be missing. I’ve just read in the official doc that streaming from a file is kind of broken. Since I don’t really know if that’s up to date, I decided to give it a try here.

  Any help or suggestions ? Alternatives ?

• Python Send FFMPEG stdout and stderr to Multiple files using for loop

  17 avril 2021, par D0n

  Here is my scripts

  


  csv_location = '/home/scripts/streams.csv'
ffmpeg_location = '/usr/bin/ffmpeg'
ffmpeglogs = '/home/scripts/ffmpeglog/'

# Open the streams list csv file
with open(csv_location) as csv_file:
    csv_reader = csv.reader(csv_file, delimiter=',')
    for row in csv_reader:
        ffmpeg_log = (ffmpeglogs + row[0]) # set the ffmpeg log to be named the stream name
        # Open log file for writing
        with open(ffmpeg_log, 'wb') as ffmpeg_output: 
            # Iterate through streams list
            for row in csv_reader:
                print(row)
                stream_output = (row[0] + ".mpeg") # stream output variable
                # Subprocess record 1 stream at a time & send the output t0 stdout & stdeer
                ffmpeg_instance = subprocess.Popen([ffmpeg_location, '-t', '10', '-i', row[1], stream_output], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
                # sent output to ffmpeg log
                ffmpeg_output.write(ffmpeg_instance.communicate()[1])


  


  Here is my CSV File

  


  Name,RTSP_URL
stream1,rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov
stream3,rtsp://wowz.streamlock.net/vod/mp4:BigBuckBunny_115k.mov
stream4,rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov


  


  So I have a script that reads a CSV file and ffmpeg records the video for 10 seconds. Then spits the output of the FFMPEG to a file. I need each camera to have its own file. Really just to log FFMPEG output for each camera. But my issue is that the FFMPEG output for multiple cameras get written to 1 file.

  


  Here is what I want to see in /home/scripts/ffmpeglog/

  


  stream1 stream3 stream4


  


  Here's what I'm actually what I see in /home/scripts/ffmpeglog/

  


  name stream1


  


• Use build_libstagefright in ffmpeg to build file .so for android

  21 décembre 2014, par OneGuilty

  In order to use ffmpeg in android , I tried to build ffmpeg by using build_libstagefright in

  ffmpeg/tools/lib_stagefright

  but it alwalys appear a error which i coundn’t solve it.

  the message in the bottom of ffmpeg/config.log is

  Anyone have the solution of this ??
