Today let me find a gstreamer of a bull fork of the killer, the mind immediately thought of a general framework and plan, with Gst-inspector first object introspection property detection, and then sacrificed Gst-launcher Broadsword for pipeline test, and finally use C to achieve the pipeline logic source code , you can implement WEBRTC-based video surveillance and live streaming services.

After two weeks of efforts, gstreamer has finally completed remote camera acquisition, UDP transmission, local display and storage as AVI files, and now I will share with you the C language program. Thank you for your comments. This program has the problem of short recording time but long playback length saved as a file. I hope you can learn how to solve it. Thank you !!!!

give the application a chance to wait for the asynchronous operation to complete.A progress update is similar to a cached message. In the same way, the application can decide to wait for the completion of the cache processing before the next state change, in the future, it may be meaningful to use progress messages for caching. Asynchronous status change~~~~~~~~~~~~~~~~~~~Gstreamer currently uses stst_state_change_async to prompt that a state of the

Global variables cannot be used when writing gstreamer elements. Because the element may be created in a process, for example, multiple queue may exist in a pipeline. Put all these variables into the class of the element and use them as member variables. If a process uses multiple elements, multiple gobjects are created. Therefore, multiple member variables are generated. If it is written as a global variable, all objects will share one, and problems

Improper use of GStreamer can easily cause memory leaks. Here are some things to note: 1, Gst_element_get_name Use G_free to release name and set to NULL 2, G_io_channel_read_line G_free release line and set to NULL 3, Gst_structure_to_string/gst_caps_to_string G_free release the return value and set to NULL 4, G_filename_to_uri G_free release the return value and set to NULL 5, Gst_pad_get_name/gst_omx_video_find_nearest_frame When not in use, you ne

GStreamer bus system is mainly used to provide users with internal elements event information. Using the GStreamer bus system, just call Gst_bus_add_watch and register a callback. The problem, however, is when the interface is invoked, and the thread used to handle the bus event. The callback is implemented internally with the glib source mechanism, and the source is attach to a gmaincontext, and a gmainloo

system clock is used.2. Base time: the global time value when the media starts from 0. It can be obtained through the _ get_time () function.3. Running time: the time elapsed when the media is in the playing state.4. Stream time: the position where the media is played (in the whole media stream ).2.

The combination of gstreamer and webrtc is a little breakthrough, gstreamerwebrtc Today, I found a fork killer in gstreamer, and quickly came up with a general framework and solution plan, using the gst-inspector to perform object introspection attribute detection first, then, the gst-launcher tool is used for Pipeline Test. Finally, the channel Logic Source Code is implemented using c to implement webrtc-

When you install GStreamer into your Ubuntu system, you need to install ffmpeg support in order to better stream media development, but in general, direct use ofsudo apt-get install Gstreamer0.10-ffmpegYou are prompted to install unsuccessfully.Before we can add PPA to your system, update the local storage index before installing:sudo add-apt-repository Ppa:mc3man/trusty-mediasudo apt-get updatesudo apt-get install Gstreamer0.10-ffmpegAfter the three
