How to configure audio or video codec in R2X
Go to Account - Advanced to configure SIP call related codec.
Sip Account: To choose which account to configure.
Audio Codec: R27 support four audio codecs: PCMA, PCMU, G729, G722. Different audio codecs require different bandwidth, users can enable/disable them according to different network environment.
Video Codec: R27 support H.264 standard, which provides better video quality at substantially lower bit rates than previous standards.
Codec Resolution: R27 support four resolutions, QCIF, CIF, VGA, 4CIF and 720P.
Codec Bitrate: To configure bit rates of video stream.
Codec Payload: To configure RTP audio video profile.
Go to Phone - Call Feature to configure multicast related codec.
Go to Intercom - RTSP to configure RTSP related codec.
RTSP Stream: To enable RTSP video and select the video codec. R27 supports H.264 video codec by default.
H.264 Video Parameters: H.264 is a video stream compression standard. Different from H.263, it provides an approximately identical level of video stream quality but a half bit rate. This type of compression is sometimes called MPEG-4 part 10. To modify the resolution, framerate and bitrate of H.264.
MPEG4 Video Parameters: MPEG4 is one of the network video image compression standard. It supports the maximum compression ratio 4000:1. It is an important and common video function with great communication application integration ability and less core program space. To modify the resolution, framerate and bitrate of MPEG4.
MJPEG Video Parameters: Called motion joint photographic experts group. It is a video encoding format, in which each image is compressed separately by JPEG. MJPEG compression can produce high quality video image and has a flexible configuration in video definition and compressed frames. To modify the resolution, framerate and bitrate of MJPEG.
