Go bindings for GStreamer (retired: currently I don't use/develop this package)

Overview

Retired. I don't use/develop this package anymore.

Go bindings for GStreamer at a very early stage of maturity.

This package is based on GLib bindings. It should be goinstalable. Try

$ go get github.com/ziutek/gst

Documentation

See examples directory and http://gopkgdoc.appspot.com/pkg/github.com/ziutek/gst

To run examples use go run command:

$ cd examples
$ go run simple.go

To run live WebM example use go run live_webm.go and open http://127.0.0.1:8080 with your browser. You probably need to wait a long time for video because of small bitrate of this stream and big buffer in you browser.

Issues
  • 'g_type_init' is deprecated

    'g_type_init' is deprecated

    I get the following error when trying to go get this library:

    # github.com/ziutek/glib
    type.go:19:1: error: 'g_type_init' is deprecated (declared at /usr/include/glib-2.0/gobject/gtype.h:669) [-Werror=deprecated-declarations]
     )
     ^
    cc1: all warnings being treated as errors
    

    I also tried running the examples, they don't work either, giving the same error.

    I'm on Arch Linux x64, Go 1.1, GCC 4.8.1.

    Added basic support for: GstAllocator, GstAppSrc, GstBuffer

    Due to lack of push-behaviour I added some basic GstAppSrc and GstBuffer support which allows to allocate buffer and push it to AppSrc element inside "need-data" handler.

    live_webm example broken in go 1.4.1

    I've tested the gstreamer bindings in osx.

    gstreamer 1.4.5, go 1.4.1 (built with swig support) are installed, as well as all the dependencies

    The simple example works ok (replacing xvimagesink for autovideosink), but the live_webm fails building and launching it as shown. Any ideas on what's going on?

    [..]
    

    I tried it with different go versions without any change in behavior.

    My current workaround is to comment out two lines in the library to not make it free the two pointers:

    func (m *Message) ParseError() (err *glib.Error, debug string) {
            var d *C.gchar
            var     e, ret_e *C.GError
    
            C.gst_message_parse_error(m.g(), &e, &d)
            // prevent segfaults by not freeing the pointer
            //defer C.free(unsafe.Pointer(e))
            //defer C.free(unsafe.Pointer(d))
    
            debug = C.GoString((*C.char)(d))
            ret_e = new(C.GError)
            *ret_e = *e
            err = (*glib.Error)(unsafe.Pointer(ret_e))
            return
    }
    

    I'm not sure, if this is the way to fix it. I guess it creates a memory leak.
