enum PixelFormat

Pixel format. Notes:

PIX_FMT_RGBA32 is handled in an endian-specific manner. A RGBA color is put together as: (A << 24) | (R << 16) | (G << 8) | B This is stored as BGRA on little endian CPU architectures and ARGB on big endian CPUs.

When the pixel format is palettized RGB (PIX_FMT_PAL8), the palettized image data is stored in AVFrame.data[0]. The palette is transported in AVFrame.data[1] and, is 1024 bytes long (256 4-byte entries) and is formatted the same as in PIX_FMT_RGBA32 described above (i.e., it is also endian-specific). Note also that the individual RGB palette components stored in AVFrame.data[1] should be in the range 0..255. This is important as many custom PAL8 video codecs that were designed to run on the IBM VGA graphics adapter use 6-bit palette components.

Enumerator:

example: av_resample_compensate(c, 10, 500) here instead of 510 samples only 500 samples would be output

decode a frame.

Parameters:

	buf	bitstream buffer, must be FF_INPUT_BUFFER_PADDING_SIZE larger then the actual read bytes because some optimized bitstream readers read 32 or 64 bit at once and could read over the end
	buf_size	the size of the buffer in bytes
	got_picture_ptr	zero if no frame could be decompressed, Otherwise, it is non zero

Returns:

-1 if error, otherwise return the number of bytes used.
