<div>Hi All,</div>
<div><br>
</div>
<div>I am looking into shmsink/shmsrc, the buffer passthrough does not contain any metadata such as pts, dts. I wonder i<em></em><span class="st">f gst_buffer_map() actually is supposed to contain that data or it only contains the memory the buffer wrapped?<br>
</span></div>
<div><br>
</div>
<div>Is there any plugin that actually passes the buffer with timestamp to another process? Is there any muxer that allows me to wrap the buffer with its metadata into another buffer so I can actually demux it out with the correct timestamp after received by
shmsrc?</div>
<div><br>
</div>
<div>Thanks,<br>
