davinci frames

after - Spring Festival came back, the use of the days before work, the first to write this article, it was written first DAVINCI DM3730 Development Strategy-- linux-2.6.32 transplant, but that article involved the kernel of things too much, not very good to write, and I have not written a new article for a long time, first published this article. Later thought, from the perspective of application usage analysis, and then step by step into the kernel

Compilation of Davinci kernel image uImage 1. copy the directory of the kernel to/root, this prevents other configurations from being damaged. cp/opt/mv_pro_4.0/montavista/pro/devkit/lsp/ti-davinci/root/-rf 2. enter the copied Directory: cd/root/ti-davinci (// or a level-1 Directory, which should contain arch and so on) 3. make menuconfig (A Kernel configuration

This article stipulates: [Host] indicates host PC Linux [Target] indicates the target board LinuxOne of DaVinci development principles-Establishing an arm Development Environment (dvevm) 1. for the DaVinci platform, Ti provides strong hardware support for the dual-core architecture. It uses DSP/BIOS to support the operation of audio and video algorithms on the DSP end, and uses the montavista Linux (MV) on

1. Where can I read the demo source code? The mvl_target_setuplinux_000020_00_10.bin package in the box is only a binary running program, right? 2. Is the CSL Library Supported by 6446 downloaded now? I do not have I have to write the timer module for testing a few days ago. What about DMA and other modules in the future? The head is dead 3. 6446 is a dual-CPU integrated chip of arm and DSP. Is it a separate programming during programming and communication through Ram? I am still developing

Do video playback, involving key frame one said, when the data from the video stream to display the image, what is the correlation between these images? Then it is necessary to understand the concept of I-frame, P-frame, B-frame, PTS, and DTS, the relationship between i,p,b frame and Pts,dts is explained as follows:Basic concepts:　I Frame: Intra-frame encoding frame also known as intra picture,i frame is usually the first frame of each GOP (a video compression technique used by MPEG), which is m
