| 1 | +=============================================================================== |
| 2 | +2009-03-10 OpenCORE 2.02 |
| 3 | + |
| 4 | +******** |
| 5 | + There is minor version number nomenclature change where the |
| 6 | + minor version is now two digits. So the previous releases |
| 7 | + in the new nomenclature are 2.00 (2.0) and 2.01 (2.1). The |
| 8 | + new release is 2.02, which is a minor version increment beyond |
| 9 | + the previous release. |
| 10 | +******** |
| 11 | + |
| 12 | +New Features |
| 13 | +- AMR-WB support added to the OMX encoder node so that it can utilize |
| 14 | + an OMX AMR-WB encoder component if it is part of the OMX core. |
| 15 | +- Buffer allocator mechanism allowing the Media I/O components to |
| 16 | + supply buffers to the OMX decoders. This method is especially useful |
| 17 | + as an alternative way to allocate video buffers. Details can be |
| 18 | + found in the new document "Guide to Supplying Decoder Buffers from |
| 19 | + the MIO Component" in the file mio_decoder_buffer_allocation_guide.pdf |
| 20 | + in the top-level doc directory. |
| 21 | + |
| 22 | +Improvements |
| 23 | +- Resolution of Valgrind and static analysis warnings in player and author |
| 24 | +- Improvements in support for .mov files in MP4 FF Parser(relaxed some checks). |
| 25 | +- Modified OMX encoder node to allow setting the AMR bitrate |
| 26 | + based on an extension interface value. |
| 27 | +- Fix inconsistencies in OSCL find method related to inclusion of the |
| 28 | + directory name with the filename. |
| 29 | +- Improvement in PVMFInfoErrorHandlingComplete in the player datapath |
| 30 | +- Refactor of the Protocol Engine node to support a plugin architecture. |
| 31 | + This improves extensibility of the module for new features in the future. |
| 32 | +- Introduce QueryInterfaceSync in PVMFNodeInterface and "all" metadata key |
| 33 | +- AMR NB and WB have conflicting meaning for frame_type and mode elements |
| 34 | +- Change the default settings related to caching for Oscl_File when |
| 35 | + using PVFile within the fileformat parsers. |
| 36 | +- Replace test.mp4 with interop clip |
| 37 | +- Update of tests for support for progressive download of AMR |
| 38 | +- OMX Khronos header files (Omx_Core.h, Omx_Component.h) capitalization |
| 39 | + changed to match that from the Khronos (previously they were all lowercase). |
| 40 | +- Updated MIO Developer's Guide in the top-level doc directory. |
| 41 | + |
| 42 | +Bugs Fixed |
| 43 | +- Memory leak when running GCF TC212 (2way-related) |
| 44 | +- MediaClockConverter divided by zero caused by timescale 0 |
| 45 | +- MP4 composer node destructor memory corruption fixed. |
| 46 | +- Fix for intermittent crash in player engine TC 105 |
| 47 | +- OMX dec node did not reset all the internal state during |
| 48 | + Reset processing. |
| 49 | + |
| 50 | +=============================================================================== |
| 51 | +2009-02-26 OpenCORE 2.1 (2.01) |
| 52 | + |
| 53 | +New Features |
| 54 | +* OpenMAX Codec-related: |
| 55 | + - Introduced the OMXConfigParser API to help in determining |
| 56 | + which OpenMAX components can support the input bitstream. |
| 57 | + It is used to narrow the list of candidate OpenMAX components |
| 58 | + to be used for playback. See the OpenMAX Core Integration Guide |
| 59 | + document in the doc directory for more information. |
| 60 | + - Added OMX AAC encoder support in the OMX encoder. |
| 61 | + - Modified to use separate component roles for AMR-NB and AMR-WB as |
| 62 | + described in the OpenMAX IL spec version 1.1.2. |
| 63 | + - Added support for a new buffer format for H.264/AVC decode and |
| 64 | + encode to allow passing multiple NALs in a single buffer. |
| 65 | + The format uses OMX_OTHER_EXTRADATA structure defined in |
| 66 | + section 4.2.33 of the OpenMAX IL spec version 1.1.2 to pass |
| 67 | + NAL lengths. See the OpenMAX Core Integration Guide document |
| 68 | + in the doc directory for more information. |
| 69 | +* Author-related: |
| 70 | + - Added support for authoring files with AAC audio. |
| 71 | + - Added support for authoring AMR-WB audio to MP4/3GP files and |
| 72 | + IETF storage format. |
| 73 | + - Added support for writing to an open file descriptor as an option |
| 74 | + instead of simply providing a filename. The file descriptor |
| 75 | + option is useful for cases where another process needs to open |
| 76 | + the file because of permissions. |
| 77 | +* Added large file support in OSCL (i.e., 64-bit file size/offset |
| 78 | + support) to handle files greater than 2 GiB on filesystems that |
| 79 | + support it. |
| 80 | +* Added rotation support in the 32-bit color-conversion class. |
| 81 | + |
| 82 | +Improvements |
| 83 | +* Removed dynamically loaded modules from the prelink map to avoid |
| 84 | + clutter and to make both the prelink map and loadable modules |
| 85 | + easier to manage. There may be an issue if a single instance of |
| 86 | + a process tries to load libraries not in the prelink map more than |
| 87 | + 256 times |
| 88 | + (See http://code.google.com/p/android/issues/detail?id=2042). |
| 89 | +* Update to the MP3 Decoder to fix security issue (oCERT_2009-002, |
| 90 | + CVE-2009-0475) |
| 91 | +* Renamed the OSCL config directory linux_nj to android to match the |
| 92 | + platform name. Replaced all references of nj with android in the |
| 93 | + codebase. |
| 94 | +* General security improvements found from static analysis in the |
| 95 | + following areas: |
| 96 | + - Buffer and type overruns and underruns |
| 97 | + - Null pointer references |
| 98 | +* Refactored the jitter buffer node into a more modular architecture |
| 99 | + for better support of different streaming use-cases and protocols. |
| 100 | +* Fixed an issue in the MP3 decoder when decoding for very of long |
| 101 | + durations (over 2 GiB of data). |
| 102 | +* General improvements found during 3GPP packet-switched streaming |
| 103 | + interoperability testing. |
| 104 | +* General improvements and resolution of issues found from module |
| 105 | + level and engine (player, author, 2-way) level unit testing. |
| 106 | + |
| 107 | +New APIs / Behaviors |
| 108 | +* Added support in the player engine to cancel a single pending |
| 109 | + command using the CancelCommand API. See the player engine API |
| 110 | + document for details. |
| 111 | +* Renumbered the author test cases to avoid issues with |
| 112 | + preprocessor conditionals changing the test numbers based on |
| 113 | + settings. Now the test numbers shouldn't change. |
| 114 | +* In the case of 3rd party OMX components that support multiple roles, |
| 115 | + returns an error if the component cannot set the role parameter |
| 116 | +* OMX components need to explicitly set nPortIndex parameter for |
| 117 | + all appropriate parameters |
| 118 | +* Added fix for buffering percentage notification in streaming |
| 119 | + scenario (see https://review.source.android.com/Gerrit#change,8699) |
| 120 | +* Updated omx shared library build configuration to separate component |
| 121 | + registration from component build |
| 122 | +* Added methods in baselibs to serialize and deserialize the UTF-16, |
| 123 | + UTF-16LE, UTF-16BE strings |
| 124 | +* Removed the iUseCPMPluginRegistry flag from the source data that was |
| 125 | + previously used to enable the content policy manager. |
| 126 | + Since the CPM pluginsare dynamically loaded, the flag is not |
| 127 | + needed and was removed. See the playerdriver.cpp for details |
| 128 | + of the change. |
