• muxing DVB subtitles into transport stream with ffmpeg

  28 novembre 2019, par user3439130

  So i have H264 video + AAC audio muxed inside transport stream (*.ts). To achive evenly spread PCR values i added muxrate tag to my command.

  ffmpeg -analyzeduration 20000000 -probesize 20M -loglevel verbose -i 1135084.m4v -i 1135084.m4a -c copy -muxrate 7982K -map 0:v:0 -map 1:a:0 -metadata:s:a:0 language=eng -metadata:s:a:0 tms_track_id=169451954 TEMP0.ts

  Since our client need DVB substitles we convert SRT to DVD with subtitle edit and then encode them to DVB with ffmpeg with this command :

  ffmpeg -analyzeduration 20000000 -probesize 20M -loglevel verbose -i TEMP0.ts -i out.da.idx -map 0 -c copy -muxrate 7992K -map 1:s -c:s:0 dvbsub -metadata:s:s:0 language=dan TEMP1.ts

  here is output from ffmpeg command :

  So i have video/audio and two dvb tracks inside one TS.

  Now im adding third subtitle and i get this warning :

  frame=32351 fps=869 q=-1.0 size= 1255936kB time=00:21:33.99 bitrate=7951.1kbits/s speed=34.8x

  frame=33416 fps=886 q=-1.0 size= 1297408kB time=00:22:16.56 bitrate=7952.0kbits/s speed=35.4x

  By this warning it seems that something is not right with DVB (0:3) Finish track.
  Playing back the file with VLC i can see that Finish subtitles (between 21:33 and 22:16) are not showing up.

  Dumping packets from 0:3 track i see that 4 packets have the same DTS/PTS values.

  Sometimes muxing subtitles in different order (for example Finish before Danish and then Swedish) would solve this problem, but i would like to know why such things are happening.

• FFMPEG recording get an error when camera is turned off

  29 novembre 2019, par Bogdan Rudnytskyi

  I have a video recording service using ffmpeg.
  When the camera is turned off, I don’t get an error and the service freezes.
  Please help me how I can configure recording so that this service crashes with an error ? (and I will use Supervisor).
  Maybe I need to insert some flag ?

• Best and latest live video streaming soloution [on hold]

  3 avril 2015, par Ford

  I have read a few old posts on StackOverflow about live video streamins, but as they are from around 2008, i assume things have moved on from then... and wonder if a current thread will be useful to me and others.
  Also looking on google gives lots of stuff, but again i dont know who is best to listen to and who is trying to sell their stuff (not that i am against paying).

  Basically what are the main points i need to know in order to add/develope a feature to a website in order to offer "1 on 1" and "1 to many" MULTIPLE live streaming webcam, with voice and text chat.

  I am quiet competent with PHP, OK with basic JavaScript (of course fine with HTMLL/css), but do not know what code i would need for client side software, or if any "off the shelf" software is suitable.
  I have played with ffmpeg and noticed this offers streaming, but i dont know if it would be suitable or the best available option.?
  I have a dedicated server with virtualization so can add a dedicated box for streaming if needed/better.

  Any info that can point me off in the right direction of how to add a live streaming service to a website would be much appreciated !
