RTSP streaming:
You can choose to enable or disable audio. Set your login credentials here, server listening port, and the stream bitrate.
(RTSP_ENC_PARAMETER variable accepts numbers only. 0=FIXQP, 1=CBR, 2=VBR, 4=CAPPED VBR, 8=CAPPED QUALITY. Currently only 2, 4, and 8 are working)
The RTSP server outputs the two supported video streams from the camera, 1080p/360p (1296p/480p for the DB3). You can choose to enable a single stream of your choice, or both. Audio is also available. Set your login credentials here, server listening port, and the stream bitrate.
(ENC_PARAMETER variable accepts numbers only. 0=FIXQP, 1=CBR, 2=VBR, 4=CAPPED VBR, 8=CAPPED QUALITY. Currently only 2, 4, and 8 are working)

the stream will be located at ```rtsp://login:password@IP_ADDRESS:8554/unicast```
Notes: If you don't set the password, then the password will be the unique MAC address of the camera, in all uppercase, including the colons... for example:. AA:BB:CC:00:11:22. It's typically printed on the camera. VLC seems to work fine for playback, ffmpeg and others have severe artifacts in the stream during playback.
Notes: If you don't set the password, then the password will be the unique MAC address of the camera, in all uppercase, including the colons... for example:. AA:BB:CC:00:11:22. It's typically printed on the camera. Higher video bitrates may overload your Wi-Fi connection, so a wired connection is recommended.

## Latest Updates
* 05-15-22: patched libcallback to support both video streams from the camera. Added support for them in run_mmc.sh.
* 05-14-22: Added ability to specify RTSP bitrate parameters. Note that changing bitrate in the mobile app will briefly reset the bitrate for the RTSP stream.
* 05-14-22: Update v4l2rtspserver, tinyalsa, alsa-lib. Patch busybox for older official FW's failing to run scripts, fix choppy/static audio in libcallback
* 05-09-22: fix bug in run_mmc.sh that did not store the wlan mac when using a wired usb or ethernet connection for the rtsp server
