• Anomalie #4549 (En cours) : Accessibilité du date picker

  13 septembre 2020, par nicod _

  Je ré-ouvre le ticket pour la notion de format attendu.

  On peut utiliser cette syntaxe pour préciser aux lecteurs d’écran le format de la date, sans qu’il n’apparaisse sur écran :

  <span class="CodeRay"><span class="tag">span> <span class="attribute-name">for</span>=<span class="string"><span class="delimiter">"</span><span class="content">champ_date</span><span class="delimiter">"</span></span><span class="tag">></span>Date<span class="tag"></span>
  
  <span class="tag">span> <span class="attribute-name">hidden</span> <span class="attribute-name">id</span>=<span class="string"><span class="delimiter">"</span><span class="content">date_desc</span><span class="delimiter">"</span></span><span class="tag">></span>Saisir une date sous la forme jj/mm/aaaa<span class="tag"></span>
  
  <span class="tag">span> <span class="attribute-name">type</span>=<span class="string"><span class="delimiter">"</span><span class="content">text</span><span class="delimiter">"</span></span> <span class="attribute-name">id</span>=<span class="string"><span class="delimiter">"</span><span class="content">champ_date</span><span class="delimiter">"</span></span> <span class="attribute-name">name</span>=<span class="string"><span class="delimiter">"</span><span class="content">date</span><span class="delimiter">"</span></span> <span class="attribute-name">aria-describedby</span>=<span class="string"><span class="delimiter">"</span><span class="content">date_desc</span><span class="delimiter">"</span></span><span class="tag">></span>
  
  </span></span></span></span>

• Display formatted date and time over frames using ffmpeg

  28 août 2020, par marcman

  I've gone through a handful of questions on here (this, this, this, etc) concerning overlaying the date and time on videos using ffmpeg, but I haven't been able to figure out the solution.

  


  I personally have found the ffmpeg documentation difficult to parse as well regarding drawing text that updates every (N) frame(s).

  


  I have the exif data from a movie specifying when it was created. I'd like to be able to emblazen that over the movie (as though it were a home video from some old VHS tape). For example, let's say I have a video from January 2, 2012 at 10:33:53. I'd like to be able to show "Jan 2, 2012 10:33:53am" on the lower right in white text. The spatial positioning and color are clear to me, but just how to go from the timestamp information I have to the formatted expansion is proving to be quite difficult for me. I have succeeded in getting a clock starting from 00:00:00.00 and counting up (using timecode and timecode_rate), but unfortunately I can't get much more than that.

  


  My question is : what is the proper datetext command that will allow me to both (a) provide the start time, and (b) format it with the proper expansion.

  As a bonus, if you can also point me to how to do this using the wonderful ffmpeg-python library, it would be even better. That library is quite good, but it does not appear to be actively maintained anymore.

  


• avformat/hlsenc : increase initial program date time precision

  18 juillet 2020, par Marton Balint

  avformat/hlsenc : increase initial program date time precision
  Also query time only once, not for every variant stream, otherwise variant
  
  streams might get a slightly different initial program date time. And we can
  
  set this unconditionally because HLS_PROGRAM_DATE_TIME flag is checked
  
  elsewhere.
