# GstMediaSource

GstMediaSource is the entry point into the W3C Media Source API. It offers functionality similar to GstAppSrc for client-side web or JavaScript applications decoupling the source of media from its processing and playback.

To interact with a Media Source, connect it to a GstMseSrc that is in some GstPipeline using gst_media_source_attach. Then create at least one GstSourceBuffer using gst_media_source_add_source_buffer. Finally, feed some media data to the Source Buffer(s) using gst_source_buffer_append_buffer and play the pipeline.
