allwinner 全志 a10 Video Decode Source code

LIBVECORE DEMO README ------------- 1) Documentation ---------------- * Read the documentation in ./doc directory. * * 1. "PMP file format.doc": introduce the file format of PMP file, helpful when * you are reading the pmp_file_parser source code. * * 2. "Libve User Guide.pkf": a guide for using the libve.a library. * 2) Directory ------------ * * 'libvecore_demo' * | * |---- 'pmp_file_parser': source code of parsing video data from a PMP file. * | * | * |---- 'vdecoder': source code of bitstream/picture frame buffer management and decoding using libvecore.a. * | * | * |---- 'vbv': source code of VBV module, responsible of bitstream frame management. * | * |---- 'fbm': source code of FBM module, responsible of frame buffer management. * | * |---- 'libvecore': libvecore.a library(It is libve). * | * |---- 'libcedarv': the controlling logic of using VBV, FBM and libvecore.a. * | * |---- 'adapter': the implement of interfacies(IVBV/IFBM/IOS/IVE) for libvecore.a. * | * |---- cdxalloc: libcedarxalloc.a, I use this library to manage the memory allocation and free. * 2) Note ------------ * 1. As the memory for VE is provided and mapped by the cedar_dev.ko driver, we implement a library named * 'libcedarxalloc.a' to manage the allocation and free operation on this memory space. The 'palloc' and * 'pfree' method used by libvecore.a are mapped to relative methods in this library. For details, see * libve_adapter.c. * * 2. Test files for this demo are in the outside directory 'libvecore_demo_test_files'. Currently this demo * supports PMP files only. * * 3. Compile this demo under folder "android2.3.4\frameworks\base\". * *
