• Annual Release of External-Videos plugin – we’ve hit v1.0

  13 janvier 2017, par silvia

  This is the annual release of my external-videos wordpress plugin and with the help of Andrew Nimmolo I’m proud to annouce we’ve reached version 1.0 !

  So yes, my external-videos wordpress plugin is now roughly 7 years old, who would have thought ! During the year, I don’t get the luxury of spending time on maintaining this open source love child of mine, but at Christmas, my bad conscience catches up with me – every year ! I then spend some time going through bug reports, upgrading the plugin to the latest wordpress version, upgrading to the latest video site APIs, testing functionality and of course making a new release.

  This year has been quite special. The power of open source has kicked in and a new developer took an interest in external-videos. Andrew Nimmolo submitted patches over all of 2016. He decided to bring the external-videos plugin into the new decade with a huge update to the layout of the settings pages, general improvements, and an all-round update of all the video site APIs which included removing their overly complex SDKs and going straight for the REST APIs.

  Therefore, I’m very proud to be able to release version 1.0 today. Thanks, Andrew !

  Enjoy – and I look forward to many more contributions – have a Happy 2017 !

  NOTE : If you’re upgrading from an older version, you might need to remove and re-add your social video sites because the API details have changed a bit. Also, we noticed that there were layout issues on WordPress 4.3.7, so try and make sure your WordPress version is up to date.

• avcodec/hevc_sei : fix amount of bits skipped when reading picture timing SEI message

  avcodec/hevc_sei : fix amount of bits skipped when reading picture timing SEI message
  The code was skipping the entire reported SEI message size regardless of
  
  the amount of bits read.
  
  While in theory safe for NALU where the picture timing SEI message is alone
  
  or at the end as we're using the checked bitstream reader, it isn't in any
  
  other situation, where every SEI message in the NALU after the picture
  
  timing one would potentially fail to parse.
  Change the function name to one more in line with the rest of file, and
  
  remove the bogus "Skipped SEI" debug message while at it.

• h264 segments timeline for live http

  18 mai 2017, par Manuel

  I want to stream h264 from IP camera through http range requests.
  Recording 10min video to file with :

  ffmpeg -i rtsp://192.168.1.128:554/ch0_0.h264 -vcodec copy -an -f mp4 -reset_timestamps 1  -segment_time 1 -t 600 -movflags empty_moov+default_base_moof+frag_keyframe video.mp4

  During the recording every second I capture the video structure with (python lib) :

  qtfaststart -l video.mp4

  I can capture the init header without any problem and also the rest of the processing video. The thing is that I don’t know how to make the timeline for each segment :

  moof 104

  mdat 41899 ---- > segment 1 104+41899

  moof 432

  mdat 831469 -----> segment 2 432+831469

  How I can capture the timeline for each segment ?

  eg :

  segment1 = from 0 to 2 sec

  segment2 = from 2 to 4 sec ...and so on
