Abstract

The invention discloses an OMAP (open multimedia application platform) hardware decoding acceleration based embedded high-definition media player and operation method thereof. The player comprises an ARM+DSP (digital signal processor) dual heterogeneous processing chip, open-source application software is carried on the ARM+DSP dual heterogeneous processing chip, the open-source application software is an MPlayer or a GSstreamer, and hardware decoding, software decoding, frame zooming and rotating of a video format are realized. High-definition hardware decoding playing of the common video format is realized by the aid of hardware, and decoding playing of an uncommon video format is achieved by the aid of software. Screen turning is achieved by the aid of DSP according to the characteristics of a screen media system, and self-adaptive playing on a horizontal screen and a vertical screen is realized.

Description

technical field [0001] The invention relates to an embedded media player, in particular to an embedded high-definition media player based on OMAP hard decoding acceleration, and also relates to an operation method of the embedded high-definition media player based on OMAP hard decoding acceleration. Background technique [0002] With the advent of the 21st century, mankind has entered the post-PC era, and some multimedia applications on the desktop have been gradually transferred to the embedded platform, and the embedded technology has been developed rapidly and widely used. Applying embedded systems to multimedia mobile terminals gives full play to the characteristics of embedded systems such as low power consumption, high integration, and strong expandability, and can achieve the effect of integrating various functions such as mobile, voice, and image. [0003] In the embedded environment, digital video is a relatively complex field in multimedia technology. How to achiev...
