2009-03-10 OpenCORE 2.02
********
There is minor version number nomenclature change where the
minor version is now two digits. So the previous releases
in the new nomenclature are 2.00 (2.0) and 2.01 (2.1). The
new release is 2.02, which is a minor version increment beyond
the previous release.
********
New Features
- AMR-WB support added to the OMX encoder node so that it can utilize
an OMX AMR-WB encoder component if it is part of the OMX core.
- Buffer allocator mechanism allowing the Media I/O components to
supply buffers to the OMX decoders. This method is especially useful
as an alternative way to allocate video buffers. Details can be
found in the new document "Guide to Supplying Decoder Buffers from
the MIO Component" in the file mio_decoder_buffer_allocation_guide.pdf
in the top-level doc directory.
Improvements
- Resolution of Valgrind and static analysis warnings in player and author
- Improvements in support for .mov files in MP4 FF Parser(relaxed some checks).
- Modified OMX encoder node to allow setting the AMR bitrate
based on an extension interface value.
- Fix inconsistencies in OSCL find method related to inclusion of the
directory name with the filename.
- Improvement in PVMFInfoErrorHandlingComplete in the player datapath
- Refactor of the Protocol Engine node to support a plugin architecture.
This improves extensibility of the module for new features in the future.
- Introduce QueryInterfaceSync in PVMFNodeInterface and "all" metadata key
- AMR NB and WB have conflicting meaning for frame_type and mode elements
- Change the default settings related to caching for Oscl_File when
using PVFile within the fileformat parsers.
- Replace test.mp4 with interop clip
- Update of tests for support for progressive download of AMR
- OMX Khronos header files (Omx_Core.h, Omx_Component.h) capitalization
changed to match that from the Khronos (previously they were all lowercase).
- Updated MIO Developer's Guide in the top-level doc directory.
Bugs Fixed
- Memory leak when running GCF TC212 (2way-related)
- MediaClockConverter divided by zero caused by timescale 0
- MP4 composer node destructor memory corruption fixed.
- Fix for intermittent crash in player engine TC 105
- OMX dec node did not reset all the internal state during
Reset processing.

2009-02-26 OpenCORE 2.1 (2.01)
New Features
* OpenMAX Codec-related:
- Introduced the OMXConfigParser API to help in determining
which OpenMAX components can support the input bitstream.
It is used to narrow the list of candidate OpenMAX components
to be used for playback. See the OpenMAX Core Integration Guide
document in the doc directory for more information.
- Added OMX AAC encoder support in the OMX encoder.
- Modified to use separate component roles for AMR-NB and AMR-WB as
described in the OpenMAX IL spec version 1.1.2.
- Added support for a new buffer format for H.264/AVC decode and
encode to allow passing multiple NALs in a single buffer.
The format uses OMX_OTHER_EXTRADATA structure defined in
section 4.2.33 of the OpenMAX IL spec version 1.1.2 to pass
NAL lengths. See the OpenMAX Core Integration Guide document
in the doc directory for more information.
* Author-related:
- Added support for authoring files with AAC audio.
- Added support for authoring AMR-WB audio to MP4/3GP files and
IETF storage format.
- Added support for writing to an open file descriptor as an option
instead of simply providing a filename. The file descriptor
option is useful for cases where another process needs to open
the file because of permissions.
* Added large file support in OSCL (i.e., 64-bit file size/offset
support) to handle files greater than 2 GiB on filesystems that
support it.
* Added rotation support in the 32-bit color-conversion class.
Improvements
* Removed dynamically loaded modules from the prelink map to avoid
clutter and to make both the prelink map and loadable modules
easier to manage. There may be an issue if a single instance of
a process tries to load libraries not in the prelink map more than
256 times
(See http://code.google.com/p/android/issues/detail?id=2042).
* Update to the MP3 Decoder to fix security issue (oCERT_2009-002,
CVE-2009-0475)
* Renamed the OSCL config directory linux_nj to android to match the
platform name. Replaced all references of nj with android in the
codebase.
* General security improvements found from static analysis in the
following areas:
- Buffer and type overruns and underruns
- Null pointer references
* Refactored the jitter buffer node into a more modular architecture
for better support of different streaming use-cases and protocols.
* Fixed an issue in the MP3 decoder when decoding for very of long
durations (over 2 GiB of data).
* General improvements found during 3GPP packet-switched streaming
interoperability testing.
* General improvements and resolution of issues found from module
level and engine (player, author, 2-way) level unit testing.
New APIs / Behaviors
* Added support in the player engine to cancel a single pending
command using the CancelCommand API. See the player engine API
document for details.
* Renumbered the author test cases to avoid issues with
preprocessor conditionals changing the test numbers based on
settings. Now the test numbers shouldn't change.
* In the case of 3rd party OMX components that support multiple roles,
returns an error if the component cannot set the role parameter
* OMX components need to explicitly set nPortIndex parameter for
all appropriate parameters
* Added fix for buffering percentage notification in streaming
scenario (see https://review.source.android.com/Gerrit#change,8699)
* Updated omx shared library build configuration to separate component
registration from component build
* Added methods in baselibs to serialize and deserialize the UTF-16,
UTF-16LE, UTF-16BE strings
* Removed the iUseCPMPluginRegistry flag from the source data that was
previously used to enable the content policy manager.
Since the CPM pluginsare dynamically loaded, the flag is not
needed and was removed. See the playerdriver.cpp for details
of the change.
