The VideoLAN Forums

I have been attempting to use VLC to multicast ambient music to speakers and other multicast capable devices around my buisness. After playing around with the different devices we have and I can get the devices to pick up the Multicast stream but they cannot play the stream due to the Marker bit. In the streams that are coming from VLC every 3rd set of packets has the Marker bit flagged and my devices interpret the flagged bit as a change to the stream and attempt to restart said stream. Upwards of 10 marked bits are sent in the stream per second so there is no way the devices are going to be able to play the multicast stream.

After reading the RFC's for multicast and RTP based traffic I am confused on VLC's use of the marker bit in the multicast stream. From my understanding the marker bit is used to denote changes in the stream but that does not appear to be the case with the Multicast stream from VLC. I have other devices that are capiable of sending multicast and they do not use the marker bit in this manner.

Can anyone explain why the marker bits are sent in such a manner and if possible is there a way to change when the marker bit is used?

Any expertise on this would be greatly appreciated!

The meaning of the market bit depends on the payload type. Refer to the relevant specification.
