Lecture Recorder x2 User Guide
In the Independent Channel Stream mode it is not possible to publish both input
sources using any of the Publish Stream options. Whether you need to send
multicast RTP stream or publish video through CDN, it can be done only for the DVI
input source.
The Publish Stream functionality is available only for the H.264 video codec.

4. Click this link and access the portal where the stream is being broadcast in
a new window.
5. In case you have selected a codec other than H.264 for streaming (MPEG4
or Motion JPEG), the system will give you a warning (see Figure 24 System
Message in Case of Excessive Bitrate Speed). Click on fix by setting H.264
codec. The codec will be set to H.264 automatically.
6. In case the bitrate of your broadcast exceeds 500 kbit/s, the system will
give you a warning (see Figure 24 System Message in Case of Excessive
Bitrate Speed). Click on fix by reducing bitrate to 500 kbit/s. The bitrate
will be set to 500 kbit/s automatically.
Note: Epiphan.tv is a demonstration service to help customers experiment
with publishing streams to content distribution networks. Therefore
certain bandwidth and performance limits are applied. To upgrade to a full
service please select one of Epiphan’s CDN partners.
