| * @short_description: Split Demuxer bin that recombines files created by |
| * the splitmuxsink element. |
| * |
| * This element reads a set of input files created by the splitmuxsink element |
| * containing contiguous elementary streams split across multiple files. |
| * |
| * This element is similar to splitfilesrc, except that it recombines the |
| * streams in each file part at the demuxed elementary level, rather than |
| * as a single larger bytestream. |
| * |
| * <refsect2> |
| * <title>Example pipelines</title> |
| * |[ |
| * gst-launch-1.0 splitmuxsrc location=video*.mov ! decodebin ! xvimagesink |
| * ]| Demux each file part and output the video stream as one continuous stream |
| * |[ |
| * gst-launch-1.0 playbin uri="splitmux://path/to/foo.mp4.*" |
| * ]| Play back a set of files created by splitmuxsink |
