Plug-in Search Path When the GStreamer program is running, search for plug-ins in the following order: PATH gst_plugin_path_1_0 or gst_plugin_path gst_plugin_ System_path_1_0 or gst_plugin_system_path Each environment variable contains a list of paths. GST_PLUGIN_PATH_1_0 environment variable if set, the Gst_plugin_path automatically expires. This facilitates the system's simultaneous installation of GStreamer

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 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
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.

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

Goal For a software library, there is no more intuitive first impression than printing a Hello world on the screen. Because we're dealing with a multimedia framework, we're going to play a video instead of Hello World. Don't be intimidated by the code below--it really works on four lines. The rest is the resource management code, C language, is the trouble. Not much to say, prepare your first GStreamer application ... Hello World Copy the following c
Goal The pipeline created by GStreamer does not need to be completely closed. There are several ways to send data to pipeline at any time, or to remove it from the pipeline. This tutorial shows you: How to send external data to pipeline How to get the data out of the pipeline How to manipulate this data Introduced There are several ways to enable an app to interact with the data flow through pipeline. This tutorial covers the simplest of these, becau
The current gstreamer version does not support x265 encoding/decoding. Therefore, you need to compile the code by yourself. This article is based on gstreamer1.3.3. You must first compile gstreamer1.3.3 and the corresponding base, good, bad, and uugly plug-ins.1. Install and compile the x265 Encoder 1. Download the source code. Open source x265 encoder official website is https://bitbucket.org/multicoreware/x265/wiki/Home Source code: Hg clone https:/

Some of the things that have been related to the low-latency transmission of the screen in recent time. Originally wanted to use GStreamer to verify that the RTP over UDP transfer h264 NAL data related, the results found that can not use Playbin to play RTP data! Admittedly, this also has its cause because RTP needs some out-of-band data, which is not simply passed through the streamTo check, however, there is no means to simply pass in the SDP to Pla

Goal Fast forward, rewind and slow down are common tricks of the trick pattern, and they have one thing in common: they all change the speed of playback. This tutorial shows you how to get these effects and how to jump frames by frame. The main contents are: How to change the speed of play, become faster or slower, forward or backward How to play a frame-by-frame video Introduced Fast Forward is a technology that plays media fast
