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. * * * Example launch line * |[ * 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 ! mad ! audioconvert * ! 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." * |[ * 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. * */ #ifdef HAVE_CONFIG_H #include "config.h" #endif #include #ifdef HAVE_STDLIB_H #include /* atoi() */ #endif #include #include #include #include "gstsouphttpsrc.h" #include "gstsouputils.h" /* libsoup before 2.47.0 was stealing our main context from us, * so we can't reliable use it to clean up all pending resources * once we're done... let's just continue leaking on old versions. * https://bugzilla.gnome.org/show_bug.cgi?id=663944 */ #if defined(SOUP_MINOR_VERSION) && SOUP_MINOR_VERSION >= 47 #define LIBSOUP_DOES_NOT_STEAL_OUR_CONTEXT 1 #endif #include GST_DEBUG_CATEGORY_STATIC (souphttpsrc_debug);
