| adler32.h |
@ingroup lavu_crypto
Calculate the Adler32 checksum of a buffer.
Passing the return value to a subsequent av_adler32_update() call
allows the checksum of multiple buffers to be calculated as though
they were concatenated.
@param adler initial checksum value
@param buf pointer to input buffer
@param len size of input buffer
@return updated checksum

Audio Sample Formats
@par
The data described by the sample format is always in native-endian order.
Sample values can be expressed by native C types, hence the lack of a signed
24-bit sample format even though it is a common raw audio data format.
@par
The floating-point formats are based on full volume being in the range
[-1.0, 1.0]. Any values outside this range are beyond full volume level.
@par
The data layout as used in av_samples_fill_arrays() and elsewhere in Libav
(such as AVFrame in libavcodec) is as follows:
For planar sample formats, each audio channel is in a separate data plane,
and linesize is the buffer size, in bytes, for a single plane. All data
planes must be the same size. For packed sample formats, only the first data
plane is used, and samples for each channel are interleaved. In this case,
linesize is the buffer size, in bytes, for the 1 plane.
