+ o Modified PCMParser and PCMParserList to return partial frame buffers at the
+ end of a WAV input file. This was needed to allow wrapping all samples into
+ an AS-02 audio file (which is clip-wrapped) in the case where the input file
+ has an odd number of samples with respect to the frame buffer size being
+ used. If there is more than one input file the length of the last buffer
+ will be determined by PCMParserList to be the shortest of the input files.
+ Prior to this change, partial samples in an input WAV file have been
+ abandoned (i.e., not written out to the MXF file). As a result, AS-DCP
+ applications will have to decide whether to abandon the partial last frame
+ (usually detected by testing frame_buffer.Size() != frame_buffer.Capacity())
+ or write it to the MXF file. Programs written to the old API will write the
+ partial frame (i.e., new behavior.) This should not be harmful since the
+ remainder of the buffer is zeroed and the output file will contain one
+ additional edit unit compared to the previous version.
+ o asdcp-wrap has been modified to test for the partial buffer and by default
+ will complain and abandon the buffer (i.e., same behavior but with a warning
+ message.) A new command line switch (-g) alters this behavior and writes
+ the buffer to the MXF file (it still warns the user that this condition is
+ present.)
+ o as-02-wrap now wraps all samples from the input file to the MXF file. There
+ is no padding, the clip is exactly the set of samples from the input.
+ o as-02 unwrap is temporarily restricted to creating wav files that are
+ aligned with the frame buffer size. This means that the output file will
+ be longer than the original WAV input in the case where the input file has
+ an odd number of samples with respect to the frame buffer size being used.
+ The pad samples are zero (silence).
+ o Modified CalcFramesFromDurationInSamples() to increment the count by one for
+ the case where the input file has an odd number of samples with respect to
+ the frame buffer size being used (previously it truncated the odd samples.)
+ o Fixed ST 429-5 / ST 2067-5 wrapping to increase header space when ancillary
+ resources are present (fixes a bug that cause the header to overflow the
+ allotted space when large numbers of PNG files were present.)
+ o Refactored GetXMLDocType() to use the XML parser.
+ o Added ParseFirstFromString() method to Kumu::XMLElement
+ o Removed Kumu::StringIsXML from the API.
+ o Added ASDCP::MXF::RGBALayout type
+ o Added J2CLayout property to JPEG2000PictureSubDescriptor
+ o Changed km_token_split() to retain empty elements in the output list
o Added PHDR wrapping for AS-02.
o Added J2CLayout property to the JPEG2000PictureSubDescriptor. This
support is preliminary: the Raw data type is being used instead of
projects / asdcplib.git / blobdiff
