• FFmpeg for marking time video based on a reference date

  29 décembre 2018, par Denio Mariz

  I am trying to mark a timestamp in a video using drawtext filter.
  FFmpeg easily marks timestamps based on localtime, gmtime or even PTS. However, I want to assign a reference time (start time) for the timestamp in order to represent the time the video was recorded (not encoded).

  Reading the documentation, I found that option basetime can be used for this purpose. However it seems that is not working or I am missing something.

  The command line I am using is :

  ffmpeg -y -i input.mp4 -filter_complex drawtext="fontfile=/tmp/UbuntuMono-B.ttf: fontsize=36: fontcolor=yellow: box=1: boxcolor=black@0.4: text='Wall Clock Time\: %{gmtime\:%Y-%m-%d %T}': basetime=1456007118" output.mp4

  By using basetime=1456007118, it was expected the start time was set to ’02/20/2016 20:25:18’ since 1456007118 is the UTC time for that time and date :

  date -d '02/20/2016 20:25:18' +"%s" # format MM/DD/AAAA hh:mm:ss
  
  1456007118

  However, no error is issued by FFmpeg and the video is marked with current GMT, ignoring basetime option.

  Any hint ?
  Thanks.

• Customizing HomeKit (using HomeBridge plug-in or building custom app ?)

  5 mai 2019, par Fréderic Cox

  I am running HomeBridge on a RBPi3 and displaying my home accessories through an iPad hub running the Home app.

  I really like it but I’m missing some things like a big clock (The iPad is hanging on my kitchen wall with screen-on display most of the day), a summary of my Google Calendar and some other nice widgets. It is not possible to add those widgets to the Home app (typically so with Apple software .. :-)) but I’m looking for a solution to achieve this.

  I have two options (at least that’s what I think) :

  1) Build my own iPad using the HomeKit API where I can then customize the app appearance and add the widgets the way I want.

  2) Using HomeBridge FFMpeg camera plugin and creating a video stream containing a big clock and some calendar item titles.

  Option 1 is the most work but also provides the flexibility. Option 2 is easier but limited in functionality. Option 2 might also be a performance overkill to have a video stream ? The video stream would provide me with the advantage that the camera widget in HomeKit is pretty big and clearly visible from distance (the clock at least).

  What do you think is the best option and how would option 2 be achieved ? How can I set up a video stream from for example a SWF file created in Adobe Animate ? Or how to achieve this dynamic info inside a video stream ?

  Any tips are most welcome ! Thanks
