gstreamer tutorial

This article describes how to use gstreamer to compile a simple MP3 player. 1. You need to use the mad decoding plug-in. Therefore, you need to install gstreamer0.10-plugins-uugly first. 2. Compile an MP3 player The following describes how to use the components provided by the gstreamer framework to implement a simple MP3 player. The data source component reads data from the disk, the filter component decod

Use activatepush_function in gstrtpjitterbuffer. C to check the activation mechanism in gstreamer. Related functions: ststst_pad_set_activatepush_function. You can refer to the document part-activation.txt under the DOC/designdirectory in the gstreamer package. This document makes the logic of pad active clearer. First, gstreamer core will call the activate meth

Recently, the boss spoke about installing gstreamer on the armv6 platform to prepare for the development of multimedia applications on ARM Linux. I encountered a lot of problems during the installation process. Take notes and give you a reference. My PC Linux is ubuntu8.10. (1) Of course, the cross-compilation environment is installed. I use codesourcery (my colleagues copy it here and you can download it for free ). After decompression is a arm-2008

Taking MP3 files as an example, there are many advantages for practicing in a common and widely used format. If there is no image, the synchronization problem will be eliminated first, and there will be no CPU/bandwidth.Not enough (becauseBitrate ratio of videoAudio is much higher). Second, we can test the full crawling of files and the compression formats that span a variety of different parameters. What's better is that the player that can be referenced by each other is also full crawling (the

Recently, gstreamer is used, so take some notes. Gstreamer is an extremely powerful and versatile framework for creating streaming media applications. /////// It use gobject, glib, etc. • Gobject instentiation• Gobject properties (Set/get)• Gobject Casting• Gobject referecing/dereferencing• Glib Memory Management• Glib signals and callbacks• Glib Main Loop //////////// It's feature contain: plugin.

Recently, gstreamer is used on the arm platform, so cross-Compilation of gstreamer is started. There are two ways to implement cross-Compilation: 1. compile on the pc platform and use the arm-linux-series tools on the Ubuntu platform for compilation. This method is fast, but the cross configuration item settings of configure are troublesome. compile on the target platform and use the target gcc tool directl

The general player structure diagram shown in Figure 1, to be able to port a full-featured open source playback, combined with my successful porting GStreamer and VLC to Novatek 667 platform experience, must consider all the modules in Figure 1 migration. The figure of vendor represents the equipment manufacturers, SOC represents the chip manufacturers. Figure 1 general structure of the player The following is a combination of Linu

1. Components (Elements)Elements (Element) are the most important concepts in GStreamer.You can transfer the data flow between the connected components (Elements) by creating a series of components (Elements) and connecting them together.Each component (Elements) has a special function interface, and for some component (Elements) function interfaces They are used to read the file data and decode the file data.Some component (Elements) function interfaces simply output the corresponding data to a

GStreamer is the equivalent of Windows DirectShow, a framework for creating media applications under Linux. Its main purpose is to build a media player. GStreamer is based on Plug-ins, with any compliant plug-ins can be conveniently inserted into the defined data flow pipeline, so you can simplify the development of media player process, improve portability. The GStream
