Problems solved by technology

Due to the complex structure of DirectShow, the source code resources are not rich enough, the cost of purchasing commercial software is high, and because commercial software does not have open source code, if there is any problem, it needs to be solved by a cooperative company, and the workload of writing an encoder by yourself is very heavy. It is large and needs to have very rich experience in DirectShow development. If you need to expand functions, you need to write DirectShow plug-ins, so it is very cumbersome

Abstract

The invention discloses a multimedia data out-of-process processing system which comprises a DirectShow component, a data export module and a data processing module; wherein, the DirectShow component is used for acquiring and outputting multimedia data, the data export module is used for exporting the multimedia data of the DirectShow component, and the data processing module is used for processing the multimedia data output by the data export module. The system of the invention can export the multimedia data of the DirectShow component to open source coded programs such as an ffmpeg coder, so as to develop multimedia applications; the system of the invention not only reduces the developing difficulty and developing cost, but also increases rich editing and expanding functions, therefore the development process of multimedia applications is more effective.

Description

technical field [0001] The invention relates to a multimedia data processing technology, in particular to a multimedia data cross-process processing system. Background technique [0002] DirectShow is a set of development kits provided by Microsoft for streaming media processing on the Windows platform, and it is released together with the DirectX development kit. DirectShow provides strong support for the capture and playback of multimedia streams. Using DirectShow, we can easily capture data from the capture card that supports the WDM driver model, and perform corresponding post-processing and even store it in a file. It supports a variety of media file formats, including ASF, MPEG, AVI, MP3 and WAV, etc. DirectShow provides an open development environment, and we can customize our own components according to our needs. [0003] In the existing DirectShow compression encoders, most of the video acquisition and compression is applied to the H.264 video compression standar...
