| /** |
| * 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. |
| * |
| * <refsect2> |
| * <title>Example launch line</title> |
| * |[ |
| * gst-launch-1.0 -v souphttpsrc location=https://some.server.org/index.html |
| * ! filesink location=/home/joe/server.html |
| * ]| The above pipeline reads a web page from a server using the HTTPS protocol |
| * and writes it to a local file. |
| * |[ |
| * gst-launch-1.0 -v souphttpsrc user-agent="FooPlayer 0.99 beta" |
| * automatic-redirect=false proxy=http://proxy.intranet.local:8080 |
| * location=http://music.foobar.com/demo.mp3 ! mpgaudioparse |
| * ! mpg123audiodec ! audioconvert ! audioresample ! autoaudiosink |
| * ]| 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." |
| * |[ |
| * gst-launch-1.0 -v souphttpsrc location=http://10.11.12.13/mjpeg |
| * do-timestamp=true ! multipartdemux |
| * ! 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. |
