• ffserver — live streaming to iOS, Android, Flash

  12 juillet 2013, par Stanislav Saranchin

  I'm creating live streaming transcoding from IPTV to Web into several formats like WebM, Flash, HLS using FFServer and FFMpeg at once.

  ffserver.conf located at http://pastebin.com/hUky5Jsh

  Translating of source-stream to FFServer :

  ffmpeg -i udp://239.192.192.1:1234 -s 560x320 http://localhost:8090/feed.ffm

  FFServer's logs showing next :

  Fri Jul 12 11:39:50 2013 127.0.0.1 - - New connection: GET /feed.ffm
  
  Fri Jul 12 11:39:50 2013 127.0.0.1 - - [GET] "/feed.ffm HTTP/1.1" 200 4175
  
  Fri Jul 12 11:39:50 2013 127.0.0.1 - - New connection: POST /feed.ffm
  
  Fri Jul 12 11:39:50 2013 Feed '/tmp/feed.ffm' stream number does not match registered feed
  
  Fri Jul 12 11:39:50 2013 127.0.0.1 - - [POST] "/feed.ffm HTTP/1.1" 200 4096

  My brain is very hot after googling solution on the Internet.

• Softwares for adding real time text to a video [on hold]

  30 juillet 2013, par user763410

  I am trying to add real time text (like weather information, stock quotes) to a video and broadcast it. My videos are going to be 2 hours long. I have been searching for decent softwares which can do the work for me. FFmpeg can do overlays only if text to be added is available fully before running ffmpeg code, so its not real time. I have not been able to able to get gstreamer to work on my hardware.

  So, My question is :
  Please suggest some softwares which can add (text)data to a video in real time.
  Please don't post comparisons as that will trigger moderator's anger ! I don't want to start a flame war. Purpose of the question is to make a list. Btw, this should work from command line rather than a GUI.

  (Ps : If the question is closed because of being "not cnonstructive, please answer it on my google docs page here.

  Thanks very much in advance.

  1 - Keep the collection of videos I have on HD in MP4 format playable online

  3 - If possible to maintain the same quality, make the MP4 file have the same size or very close to the original file in AVI
