• FFMPEG -ss 00:22:58 -to 01:37:45 -i input.mkv -c copy output2.mp4 first 2 seconds image is frozen

  15 août 2022, par g3443tdfgdfgdfg

  i'm making clips from an .mkv file using ffmpeg. First i used

  


  ffmpeg -i input.mkv -ss 00:22:58 -to 01:37:45 -c:v copy -c:a copy output.mp4 


  


  but the first 1-2 seconds were only sound without image. Now i'm using the command

  


  ffmpeg -ss 00:22:58 -to 01:37:45  -i 2022_05_26-ABCNews.mkv -c copy output2.mp4 


  


  But even tho the first seconds now have image they still look kind of patchy and frozen, i understand that this might be due to the nature of the .mkv file itself, but i wanted to know if anyone have any command that better perform this function and allow to save those first 1-2 seconds.

  


• How to to add additional metadata to individual frames, DDB's, when creating an AVI file with ffmpeg

  6 décembre 2019, par Totte Karlsson

  I’m creating avi videos from device dependent bitmaps, DDB’s.

  The pipeline is quite simple, a GigE camera provides frame by frame, and each frame, a DDB, is piped to a ffmpeg process creating a final AVI file, using h264 compression.

  These videos are scientific in nature, and we would like to store/embed experimental hardware information, such as the states of a few digital lines, with each frame.
  This information need to be available in the final avi video

  Question is, is this possible ?

  Looking at this : https://docs.microsoft.com/en-us/windows/win32/api/wingdi/ns-wingdi-bitmap it does not seem that adding additional data to the DDB themselves is possible, but I’m not sure.

• Evolution #2822 : HTML des modèles de pagination

  30 mars 2021, par cedric -

  et voici la PR https://git.spip.net/spip/spip/pulls/147

  A noter que sur le core et les plugins le markup conteneur a été changé partout déjà https://git.spip.net/spip/spip/commit/e3d7c4bb8cea7ba3c70636f25a7275ed8454aacb
  mais ça va aussi impacter tous les plugins dans la nature, Fabrique, et donc tous les plugins générés par Fabrique.

  Bonne nouvelle : ils peuvent changer leur markup sans casser la compat 3.2 et sans attendre la sortie de SPIP 3.3
