/**
|
|
* SECTION:element-souphttpsrc
|
|
*
|
|
* This plugin reads data from a remote location specified by a URI.
|
|
* Supported protocols are 'http', 'https'.
|
|
*
|
|
* An HTTP proxy must be specified by its URL.
|
|
* If the "http_proxy" environment variable is set, its value is used.
|
|
* If built with libsoup's GNOME integration features, the GNOME proxy
|
|
* configuration will be used, or failing that, proxy autodetection.
|
|
* The #GstSoupHTTPSrc:proxy property can be used to override the default.
|
|
*
|
|
* In case the #GstSoupHTTPSrc:iradio-mode property is set and the location is
|
|
* an HTTP resource, souphttpsrc will send special Icecast HTTP headers to the
|
|
* server to request additional Icecast meta-information.
|
|
* If the server is not an Icecast server, it will behave as if the
|
|
* #GstSoupHTTPSrc:iradio-mode property were not set. If it is, souphttpsrc will
|
|
* output data with a media type of application/x-icy, in which case you will
|
|
* need to use the #ICYDemux element as follow-up element to extract the Icecast
|
|
* metadata and to determine the underlying media type.
|
|
*

|

|

* ! audioresample ! alsasink
|
|
* ]| The above pipeline will read and decode and play an mp3 file from a
|
|
* web server using the HTTP protocol. If the server sends redirects,
|
|
* the request fails instead of following the redirect. The specified
|
|
* HTTP proxy server is used. The User-Agent HTTP request header
|
|
* is set to a custom string instead of "GStreamer souphttpsrc."

* ! image/jpeg,width=640,height=480 ! matroskamux
|
|
* ! filesink location=mjpeg.mkv
|
|
* ]| The above pipeline reads a motion JPEG stream from an IP camera
|
|
* using the HTTP protocol, encoded as mime/multipart image/jpeg
|
|
* parts, and writes a Matroska motion JPEG file. The width and
|
|
* height properties are set in the caps to provide the Matroska
|
|
* multiplexer with the information to set this in the header.
|
|
* Timestamps are set on the buffers as they arrive from the camera.
|
|
* These are used by the mime/multipart demultiplexer to emit timestamps
|
|
* on the JPEG-encoded video frame buffers. This allows the Matroska
|
|
* multiplexer to timestamp the frames in the resulting file.
