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. 129 130 =============================================================================== 131 2009-01-26 OpenCORE 2.0 (2.00) 132 133 New Features 134 - Consolidation of the clock logic into a common clock object 135 (PVMFMediaClock).
