| This example pipeline will encode a test video source to a an MPEG1 |
| elementary stream (with Generic MPEG1 profile). |
| <p> |
| Likely, the <a class="link" href="gst-plugins-bad-plugins-mpeg2enc.html#GstMpeg2enc--format" title="The “format” property"><span class="type">“format”</span></a> property |
| is most important, as it selects the type of MPEG stream that is produced. |
| In particular, default property values are dependent on the format, |
| and can even be forcibly restrained to certain pre-sets (and thereby ignored). |
| Note that the (S)VCD profiles also restrict the image size, so some scaling |
| may be needed to accomodate this. The so-called generic profiles (as used |
| in the example above) allow most parameters to be adjusted. |
