| 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 | |

| 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. |
