  541. argument instead of a const uint8_t *buf / int buf_size pair.
  542. 2009-04-03 - r18321 - lavu 50.3.0 - av_fifo_space()

  548. Convert the pixel formats PIX_FMT_ARGB, PIX_FMT_RGBA, PIX_FMT_ABGR,
  549. PIX_FMT_BGRA, which were defined as macros, into enum PixelFormat values.
  550. Conversely PIX_FMT_RGB32, PIX_FMT_RGB32_1, PIX_FMT_BGR32 and
  551. PIX_FMT_BGR32_1 are now macros.
  552. avcodec_get_pix_fmt() now recognizes the "rgb32" and "bgr32" aliases.
  553. Re-sort the enum PixelFormat list accordingly.
  554. This change breaks API/ABI backward compatibility.
  555. 2009-03-22 - r18133 - lavu 50.1.0 - PIX_FMT_RGB5X5 endian variants

  558. PIX_FMT_BGR565BE, PIX_FMT_BGR565LE, PIX_FMT_BGR555BE, PIX_FMT_BGR555LE.
  559. 2009-03-21 - r18116 - lavu 50.0.0 - av_random*

  566. and av_fifo_realloc2.
  567. In addition, the order of the function arguments of av_fifo_generic_read
  568. was changed to match av_fifo_generic_write.
  569. The AVFifoBuffer/struct AVFifoBuffer may only be used in an opaque way by
  570. applications, they may not use sizeof() or directly access members.
  571. 2009-03-01 - r17682 - lavf 52.31.0 - Generic metadata API
  572. Introduce a new metadata API (see av_metadata_get() and friends).
  573. The old API is now deprecated and should not be used anymore. This especially
  574. includes the following structure fields:
