RTSP does not work properly #89

Open baerni opened 5 years ago

baerni commented 5 years ago

I have a problem with the RTSP. I checked in a few applications. RTSP works very rarely, each time it either rejects the connection or shows a black screen. Several times a day a smooth image from the camera will appear. Often I have to reboot camera and sometimes the interface does not work and I have to disconnect the camera from the power supply. I have Yi Outdoor, yi-hack-v4 0.2.0, rtspv4__1.0.0

owenworley commented 5 years ago

I see a similar issue. Yi outdoor 1080, latest hack b4 with license etc.

Rebooting the camera means it will work for some hours, but eventually it will get to a state where it returns a blank stream on RTSP. Funnily enough, MQTT is still triggered for motion, but video is blank. Interesting.

Kilberz commented 5 years ago

I also have this issue, the stream to VLC works fine but using some CCTV Monitoring Software I get a successful connection but a black video feed. Please help!

hemm would like to know if this going to be a problem

This is not the same as my problem. My issue is that rtsp does not work at all no vlc, no motioneye, no homebridge/homekit, no nothing.... whilst the native yi app does work and shows video.

I am assuming that there is some issue with the services that convert the video into rtsp format, or the rtsp streaming process itself.....

I have run 'ps aux' on camera before and after the bug happens, but I cannot see much difference - i could be wrong, buit it doesnt look like anything is crashing/not running at this point.

If someone could tell me what commands to run via SSH to kill and restart the services responsible for RTSP then I can give those a try to see if it is indeed an issue there, otherwise im not sure where to start diagnosing this. :(

I'm also experiencing the same issue on my Yi Outdoor 1080p camera. Yi Home app works fine but the RTSP stream specifically does not work. I've tried accessing it via VLC with no luck. I have access to the RTSP page and it's enabled along with the HD stream but I'm not getting any stream at the supposed address.

TheCrypt0 commented 5 years ago

Thank you for the report. I don't have a Yi Outdoor cam but if you could give me the model number (it should be on the camera below a QR code) I'll try to get one from Amazon or eBay.

If there is anything I can do to get logs/try restarting process/etc please tell me, I am familiar with ssh/shell stuff

Sure, you can connect to the camera via SSH and manually start viewd (see --help for all the parameters) and then rtspv4 (opening two shells would be preferred).

If something goes wrong you should see a warning or error message from one of those programs.

owenworley commented 5 years ago

Will do this tonight and see if I can recreate the problem and capture the output

AndreVallestero commented 5 years ago

@TheCrypt0 Here's the output of running viewd and rtspv4 image

These were the running processes image

TheCrypt0 commented 5 years ago

@AndreVallestero Thank you for the screenshots.

Just guessing, do you have a chinese model? It may happen that the encoder process stops if it detects that isn't in the right region.

AndreVallestero commented 5 years ago

@TheCrypt0 I don't believe I have a Chinese model. It was purchased from Amazon and it works fine with the international version of the app.

ghost commented 4 years ago

I have similar problems with my Yi Outdoor Camera. If I log in via SSH I don't see viewd & rtspv4 running, if I start them manually (as deamon) they will work, but after a while the stream becomes unresponsive and if I log in via SSH same result no viewd & rtspv4 running. Any help or ideas?

derDeno commented 4 years ago

same problem over here

Scope666 commented 4 years ago

Also having this problem. RTSP is available / unavailable in almost a predictable pattern. Will try and capture some logs.

EDIT: OK, monitored the stream, and this error ALWAYS appears right when the stream drops:

[ ERROR ] dev[0] - The frames available (151) are more than than half of the maximum (300) frames. [ ERROR ] dev[0] - Preventing overlapping read, glitches in the stream may occur.

EDIT 2: Tested on both Yi Outdoor and Yi Home 27US and the frames available error is exactly the same. This seems to be a fundamental problem with viewd itself.

TheCrypt0 commented 4 years ago

Thank you for the report, I had to implement the feature to "prevent overlapping read" because sometimes the RTSP server was too slow to catch up with the frames provided by the camera.

The logic behind that feature is:

Normal situation | ======================== BUFFER ======================== | | -----------------------------R+++W---------------------- | | ======================================================== |

Overlapping read situation | ======================== BUFFER ======================== | | ++++++++++++++++++++++++++++++++++++++W-----R+++++++++++ | | ======================================================== |



As you can see, the reading pointer is too slow it might get caught by the writing one and cause issues.

Anyway, it shouldn't happen this often.. could you please try with the SD stream and see if the issue persists?
Scope666 commented 4 years ago

Thanks for that very detailed explanation. I have already tried the SD stream, as well is disabling EVERYTHING else on the camera(s) to free up as much CPU as possible.

I have an idea, since the RTSP server portion is having a hard time keeping up, what about having it process every other frame, perhaps with a switch option (-T or something)

Many NVR's record at 15 FPS, these Yi's seem to put out 20 FPS, so we have a bit to spare.

IMHO A 10 FPS stable stream would be MUCH more useful than a 20 FPS stream that drops / restarts every 60 seconds or so.

Screenshot from Blue Iris showing the amount of stream drops: (yioutdoor = 718 times, Yi Home = garage = 8 during an 11 hour period) Both have excellent Wi-Fi signal strength

What commands are you using to restore the daemons? I’m looking to implement a temporary hack by scripting on interval/something Else like that.

alpat59 commented 4 years ago

I'm having the same your issues (even if the wifi signal is quite perfect). Currently RTSP stream is unusable. Is there some news about possible fixing? Thank you for your support

Scope666 commented 4 years ago

Just checked mine again. Both are running SD streams only, no audio, cloud turned OFF, ftp off, etc:

For some reason the Outdoor drops WAY more often.

I think this could be fixed by limiting the frame rate so the buffer doesn't keep running out. (see my idea above)

andyjenkinson commented 4 years ago

Sorry for butting in; just having a browse through the project as thinking about using a couple of my Yi cameras for a project but haven't used it yet. I happened to read this issue and had some thoughts.

I believe I understand what the check is there to prevent, but unsure what it does when it finds this occurs, does it end the stream? I would expect to drop frames if processing is not keeping up with new data, especially for a streaming protocol. Can you just repeat the last frame and skip reading the "real" one until it catches up?

As for the root cause, I think /tmp/view is memory but does the output get written to disk (i.e. SD card)? If so writes to the card could be the cause if this blocks reading the next frame? I would be tempted to try to observe how reads from/writes to /tmp/view change over time (e.g. is the buffer being read smoothly but steadily falls behind, or do reads hang for long periods doing 'nothing' while writes continue?)

grungeguitarist commented 4 years ago

I was thinking about buying the RTSP server functionality for all my cameras (esp. for my Yi outdoor cams). But if it's so unstable/unusable, I won't spend any money on it. Too bad the problem won't get fixed.

chriseckman commented 4 years ago

Capture I'm experiencing the same issue with a Yi Outdoor 1080p. The RTSP is working with VLC however it will not work on Shinobi. I just get a black screen. Anyone find a fix or work around for this?

chriseckman commented 4 years ago

I was able to fix the issue and got it running. Turned out unraid will not write to an unassigned mounted NTFS drive.

barc593 commented 4 years ago

Im getting unstable rtsp, on yi dome 720p, where can i find this prevent overlapping feature?

@chriseckman, could you please provide more details on your workaround ?

Did you ever find a solution for this? I have an NVR with a couple of Yi Dome 1080p and after sometime the live feeds freeze and after a refresh, the feed for each camera goes black. Basically something is causing the cameras to loose connection. I am using the low quality RSTP feed on TCP on all cameras and the issue still persist. The only way is to either reboot the camera, reboot the NVR or re-enter the password on the NVR on each camera, which basically causes it to reconnect.

barc593 commented 2 years ago

It's a known issue, will not be solved. Sell the camera get a cheap v380 works much better

I was able to get the problem solved, thanks to RoleoRoleo from yi-hack Mstar. This fix is for the rtsp server file for the 1080p Dome and Yi Home 720p. He was able to update or modify the rtsp server and it now automatically connects immediately when something may go wrong with the live feed. Below is the link of the long chat troubleshooting the issue and how it was solved. I know this is the issues section for the Yi Outdoor, but my guess is the same fix. RoleoRoleo, not only provided me with a fix for the 1080P Dome from his firmware, but also just kind enough to provide me the RTSP sever for the 720p Home firmware from another Yi-Hack firmware.

Maybe Crypt0 can do the same here for the Yi Outdoor.

This alternate rtsp server doesn't run on the Yi Outdoor, I believe it has a different CPU.

/tmp/sd # ./rtsp_server_yi -r low -a alaw
Segmentation fault

Earlier binary he posted throws a different error:

/tmp/sd # ./rtsp_server_yi -r low -a alaw

That fix is for the rtsp server file for the 1080p Dome and Yi Home 720p. RoleoRoleo gave me the files for the 720p yi home and 1080p dome indoor. Maybe crypto can look into it. All I know my cameras are working fine now. I just wanted to share the info here just in case it could provide a fix also. Maybe someone can update the RTSP server for the Yi Outdoor Cameras.
