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

49 * web server using the HTTP protocol. If the server sends redirects,
50 * the request fails instead of following the redirect. The specified
51 * HTTP proxy server is used. The User-Agent HTTP request header
52 * is set to a custom string instead of "GStreamer souphttpsrc."

58 * ]| The above pipeline reads a motion JPEG stream from an IP camera
59 * using the HTTP protocol, encoded as mime/multipart image/jpeg
60 * parts, and writes a Matroska motion JPEG file. The width and
61 * height properties are set in the caps to provide the Matroska
62 * multiplexer with the information to set this in the header.
63 * Timestamps are set on the buffers as they arrive from the camera.
64 * These are used by the mime/multipart demultiplexer to emit timestamps
65 * on the JPEG-encoded video frame buffers. This allows the Matroska
66 * multiplexer to timestamp the frames in the resulting file.
