Below are some examples how to record video streams with various utilities.

|
||||
#### gstreamer
|
||||
|
||||
* rtsp h264 stream:
|
||||
|
||||
`gst-launch-1.0 rtspsrc location=rtsp://192.168.1.10:554/stream=0 ! rtpjitterbuffer ! rtph264depay ! h264parse ! mp4mux ! filesink location=stream0_h264.mp4 -e`
|
||||
|
||||
* rtsp h265 stream:
|
||||
|
||||
`gst-launch-1.0 rtspsrc location=rtsp://192.168.1.10:554/stream=0 ! rtpjitterbuffer ! rtph265depay ! h265parse ! mp4mux ! filesink location=stream0_h265.mp4 -e`

## How to login inside original firmware
|
||||
|
||||
Information applicable only for XM-based camera firmware.
|
||||
|
||||
### Enable telnet server
|
||||
|
||||
In U-Boot console:
|
||||
|
||||
```
|
||||
setenv telnetctrl 1; saveenv
|
||||
```
|
||||
|
||||
### Connect with telnet
|
||||
|
||||
```
|
||||
LocalHost login: root
|
||||
Password: xmhdipc
|
||||
Welcome to HiLinux.
|
||||
```
|
||||
|
||||
Also can try [other pairs](https://gist.github.com/gabonator/74cdd6ab4f733ff047356198c781f27d)
|
||||
|
||||
### Optional: enable Linux kernel verbose boot (where armbenv exists)
|
||||
|
||||
```
|
||||
# armbenv -s xmuart 0
|
||||
# reboot
|
||||
```
|
||||
|
||||
Or in case where XmEnv exists:
|
||||
|
||||
```
|
||||
# XmEnv -s xmuart 0
|
||||
# reboot
|
||||
```
|
||||
### Enable telnet without even open your camera (remotely)
|
||||
|
||||
* Find proper zip with recent firmware update using [link](https://translate.google.com/translate?hl=en&sl=ru&tl=en&u=https%3A%2F%2Fwww.cctvsp.ru%2Farticles%2Fobnovlenie-proshivok-dlya-ip-kamer-ot-xiong-mai) and download it.
|
||||
|
||||
* Unzip it and choose proper `bin` file from several options.
|
||||
|
||||
* It's recommended update your camera using this stock firmware without
|
||||
modifying it. It will help understand possible issues. Use `General...` if
|
||||
not sure which option you want.
|
||||
|
||||
* Unzip `bin` file as it would be ordinary zip archive.
|
||||
|
||||
* Copy `add_xmuart.sh` from `utils` directory of the repository inside directory
|
||||
with unpacked files.
|
||||
|
||||
* Run `./add_xmaurt.sh` and then ensure that `u-boot.env.img` has
|
||||
`xmuart=1telnetctrl=1` near the end of file.
|
||||
|
||||
* Repack `bin` file adding changed `u-boot.env.img` there like this: `zip -u General_IPC_HI3516EV200_85H30AI_S38.Nat.dss.OnvifS.HIK_V5.00.R02.20200507_all.bin u-boot.env.img`
|
||||
|
||||
* Upgrade camera using new `bin` file

## Commands to measure chip temperature on various SoCs

## Direct streaming to YouTube
|
||||
|
||||
YouTube offers not only LiveStreming but also can record this stream.
|
||||
|
||||
Up to 12 hours of LiveStream can be recorded.
|
||||
|
||||
Direct streaming to YouTube is possible but not currently supported by OpenIPC.
|
||||
|
||||
### Direct streaming can be done with MiniHttp
|
||||
|
||||
Direct streaming to YouTube could be done with the help of RTMP but there are currently no plans add this protocol to the main streamer MiniHttp.
|
||||
|
||||
### Direct streaming can be done with FFMPEG
|
||||
|
||||
There are two modes available: "old one", H264 over RTMP an a "new one", H265 over HLS.
|
||||
|
||||
Both methods were not tested in production and still in development mode. See following links for details:
|
||||
|
||||
### H264 over RTMP
|
||||
|
||||
Navigate to the compiled package [H264 over RTMP](https://github.com/ZigFisher/Glutinium/tree/master/hi35xx-ffmpeg/files)
|
||||
|
||||
Copy file **silence.aac** to /usr/lib/
|
||||
|
||||
and file **ffmpeg** to /usr/sbin/
|
||||
|
||||
Also set execution permission:
|
||||
|
||||
`chmod +x /usr/sbin/ffmpeg`
|
||||
|
||||
Run ffmpeg with the following parameters:
|
||||
|
||||
ffmpeg -stream_loop -1 -i /usr/lib/silence.aac -rtsp_transport udp -thread_queue_size 64 -i rtsp://127.0.0.1:554/stream=0 -c
|
||||
:v copy -c:a copy -f flv rtmp://a.rtmp.youtube.com/live2/<your key>
|
||||
|
||||

||||
