| <p>Reads buffers from sequentially named files. If used together with an image |
| decoder, one needs to use the <a class="link" href="gst-plugins-good-plugins-multifilesrc.html#GstMultiFileSrc--caps" title="The “caps” property"><span class="type">“caps”</span></a> property or a capsfilter |
| to force to caps containing a framerate. Otherwise image decoders send EOS |
| after the first picture. We also need a videorate element to set timestamps |
| on all buffers after the first one in accordance with the framerate.</p> |
| <p>File names are created by replacing "%d" with the index using <code class="function">printf()</code>.</p> |
