This folder contains development snapshots of the bmx source code and binaries.


Snapshot 2016-07-05
-------------------

Features:
* raw2bmx supports same AS-11 functionality as bmxtranswrap
* add option to set / override various AVC MXF descriptor properties
* merged-in the AVC branch
* add embedded XML support to RDD-9/D-10
* add MCA label support to RDD-9
* add AS-11 X7 and X8 labels
* changed the meaning of the 'repeat' option in MCA labels definition file
* add audio channel assignment label support to RDD-9
* support track mapping to all clip types
* support silence channels and tracks in track mapping
* support drop frame timecode in AS-11 segmentation definition file
* add option to set MXF header metadata filler size
* added the bmxtimecode utility

Bug fixes:
* fix RP2057 scheme label version byte
* apps: remove bogus AS-10 "Unknown framework..." warning
* h264dump: fix dpb_output_delay property name



Snapshot 2016-03-30
-------------------

The avc_branch_bmx-win32-exe-snapshot-20160330 package contains 32-bit Windows
binaries for the bmx applications in the 'avc' branch. The 'avc' branch
contains experimental code to support general (e.g. Long GOP) AVC / H264 in MXF.


Features:
* preliminary support for AMWA AS-11 X1 to X4. The variants that don't use
  RP 2057 AVC-Intra, e.g. Long GOP, require the 'avc' branch.
* support for AMWA AS-10
* support for embedding XML / text objects (SMPTE RP 2057)
* support for multi-channel audio tracks and labels (SMPTE ST 377-4)
* support for reading non-seekable MXF streams containing AVC-Intra or D-10
* support for memory-mapped MXF file access in Visual C++ builds only
* bmxparse application showing raw essence properties extracted by the essence
  parser classes
* default Material Package Track Number is now 0. The AMWA AS-02 and AS-11 UK
  DPP flavours set it to a non-zero value
* removed frame rate restrictions from VC-3 (Avid DNxHD)
* apps: add options to disable tracks by type
* avid: always output display and sampled x/y offset properties
* mxf2raw: show display x/y offset if present in file

Bug fixes:
* mxf2raw: fix UL/UUID detection for the URN text representation
* h264dump: fix buffering period SEI parsing
* avid: include pre-charge in physical source package timecode calculation

Notes:
* raw2bmx is currently missing some of the AS-11 X1 to X4 functionality,
  including MCA labelling. The workaround it to wrap the raw essence first using
  raw2bmx and then re-wrap using bmxtranswrap.



Snapshot 2015-06-03
-------------------

Features:
* support AVC-Intra Class 200
* add RIP to D-10 flavour
* RDD-9 flavour supports ANC and VBI data, SMPTE ST 436
* add basic (not optimised) file access over HTTP (Linux only)
* RDD-6 XML: change linear level to dB levels and change dialnorm to a signed value
* add support for VC-3 1244, 1258, 1259 and 1260 compression schemes
* apps: add option to set Material Package Track Number to 0
* apps: change default flavour to OP-1A
* bmxtranswrap: option to copy across AS-11 descriptive metadata
* bmxtranswrap: support stdin as input
* raw2bmx: assume variable D-10 input frame sizes and add option to override
* raw2bmx: support multi-channel raw PCM inputs
* mxf2raw: default to showing information if no options are provided
* h264dump: show rbsp_stop_one_bit info
* movdump: add stbl soun output

Bug fixes:
* AS-11: fix Track ID clash between data track (e.g. ST 436) and DM tracks
* mxf2raw: fixed display x/y offset to be a 32-bit signed integer
* mxf2raw: fix --file-chksum-only output
* avoid recursive Source Clips references and check for duplicate Package identifiers
* MSVC: updates to support msbuild usage
* movdump: use _stati64 to fix large file support on Windows
