• avfilter/avfilter : Add numbers of (in|out)pads directly to AVFilter

  12 août 2021, par Andreas Rheinhardt

  avfilter/avfilter : Add numbers of (in|out)pads directly to AVFilter
  Up until now, an AVFilter's lists of input and output AVFilterPads
  
  were terminated by a sentinel and the only way to get the length
  
  of these lists was by using avfilter_pad_count(). This has two
  
  drawbacks : first, sizeof(AVFilterPad) is not negligible
  
  (i.e. 64B on 64bit systems) ; second, getting the size involves
  
  a function call instead of just reading the data.
  This commit therefore changes this. The sentinels are removed and new
  
  private fields nb_inputs and nb_outputs are added to AVFilter that
  
  contain the number of elements of the respective AVFilterPad array.
  Given that AVFilter.(in|out)puts are the only arrays of zero-terminated
  
  AVFilterPads an API user has access to (AVFilterContext.(in|out)put_pads
  
  are not zero-terminated and they already have a size field) the argument
  
  to avfilter_pad_count() is always one of these lists, so it just has to
  
  find the filter the list belongs to and read said number. This is slower
  
  than before, but a replacement function that just reads the internal numbers
  
  that users are expected to switch to will be added soon ; and furthermore,
  
  avfilter_pad_count() is probably never called in hot loops anyway.
  This saves about 49KiB from the binary ; notice that these sentinels are
  
  not in .bss despite being zeroed : they are in .data.rel.ro due to the
  
  non-sentinels.

• decklink : support all valid numbers of audio channels

  20 décembre 2015, par Matthias Hunstock

  decklink : support all valid numbers of audio channels
  As it is already written in the documentation, BMD DeckLink cards
  
  are capable of capturing 2, 8 or 16 audio channels (for SDI Inputs).
  
  Currently the value is hardcoded to 2. Introduces new option.
