<div dir="ltr">Hi,<br><br>in Onvif and Hikvision specification for edge recording access there is an extra header information to add in PLAY command:<br><br>Onvif Specification:<br><br><a href="https://www.onvif.org/specs/stream/ONVIF-Streaming-Spec-v211.pdf" target="_blank">https://www.onvif.org/specs/<wbr>stream/ONVIF-Streaming-Spec-<wbr>v211.pdf</a><br><br>6.4.2<br>Rate-Control header field <br>This specification introduces the Rate-Control header field, which may be either “yes” or “no”. <br>If the field is not present, “yes” is assumed, and the stream is delivered in real time using <br>standard RTP timing mechanisms. If this field is “no”, the stream is delivered as fast as <br>possible, using only the flow control provided by the transport to limit the delivery rate. <br>The important difference between these two modes is that with “Rate-Control=yes”, the server <br>is in control of the playback speed, whereas with “Rate-Control=no” the client is in control of <br>the
playback speed. Rate-controlled replay will typically only be
used by non-ONVIF specific clients as they will not specify
“Rate-Control=no”. <br><div><br></div><div><br></div>In the offical version of live555 this field is missing ( RequestRecord class ) probably because it is a specific onvif field.<br><br><div>i
think that a standard way to have this ( and other ) field could be the
adding of a generic extra header in RequestRecord class.<br><br>is it possible ?</div><div><br></div><div>Regards.</div><div>Gennaro Gallo<br></div><br></div>
