| 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. |
