Having Trouble Viewing Streams on iOS

[huyqt]

Hello,

I'm having some trouble viewing streams on iOS. It looks like it attempts to direct stream but the process just times out with no video feed. [11/24/2020, 2:41:56 PM] [Shinobi] ShinobiStreamingDelegate using direct camera source: rtmp://192.168.250.14/bcs/channel0_main.bcs?channel=0&stream=0&user=XXX&password=XXX [11/24/2020, 2:54:06 PM] [Shinobi] killing: JZXytNMpRT => ffebc5-de51-4aee-b378-24ab59d3d22a => PID: 11864

Or if I try to go through the non-direct streaming route, ffmpeg dies immediately: [11/24/2020, 2:19:19 PM] [Shinobi] ShinobiStreamingDelegate using direct camera source: rtsp://XXX:XXX@192.168.250.14:554/h264Preview_01_main [11/24/2020, 2:19:47 PM] [Shinobi] ffmpeg exited with code: 1 and signal: null (error)

I've also read in your other issue that there is a hardcoded resolution that you may expect (which looks like it's 16:9 vs my 4:3 640x480).

In my case, I setup a primary recording stream at full resolution on Shinobi and added second input stream for viewing (via https://hub.shinobi.video/articles/view/w8azEAI2peYeNul). I was wondering if it was possible to point the Homebridge plugin to this secondary stream location.

You'll see that there's a stream in there for channel0_main.bcs/channel0_sub.bcs for streaming via RTMP. Though it looks like the streams[0] is correctly pointing to my HLS stream that's 640x480.

From what I saw in the code, in the failing direct stream case, it's pulling the auto_host URL instead of leaving the streams[0] but if I somehow configured Shinobi to have HomeBridge to not direct stream, I got the ffmpeg error (though I verified I can load the m3u8 link in safari).

Also, can you share your Shinobi camera config.json to compare with what's in mine to know what you're expecting?

Thank you!

Hi. Thanks for your detailed analysis. If you can wait a few days I’ll try to dig into it on the weekend.

I've cleaned up the horrible embedded json produced by shinobi for both your config and mine in the attached zip.

Archive.zip

I can tell you a number of things, but no clear answer at this stage....

Firstly, 4:3 should be fine, this is what the plugin is hard coded to:

https://github.com/vectronic/homebridge-shinobi/blob/master/src/shinobiMonitorAccessory.ts#L71

Secondly I am pretty sure, unless the auto_host route is taken, I don't think it will work. The reason is that the streams[0] entry always seems to be a relative URL. I believe I never tested this as I always wanted to use a direct camera stream. (To be honest I thought I would be the only person ever using this plugin!).

In the auto_host scenario for yourself, I think it will only work if the details are 640x360@20fps as per the hard coded config above.

Even in the case of auto_host the plugin still needs to use FFmpeg to re-stream the feed into SRTP. I have ever only used RTSP as the FFmpeg source. I am unsure about using RTMP. And I am even more doubtful about HLS as a source. That said, FFmpeg is excellent at dealing with anything you give it as input.

The URL to your second stream appears in a different place in the shinobi config which this plugin doesn't consider: details.input_maps[0].fulladdress.

I think the plugin logic would need to change as follows:

• make usage of auto_host configurable
• if not using auto_host, or it is not available, use details.input_maps[0].fulladdress (and completely ignore streams)

If the above logic was implemented:

• in my scenario I would enable usage of auto_host
• in your scenario you would disable it. For your case it would then use details.input_maps[0].fulladdress which points at your sub-stream.

However you would still need to confirm that RTMP works if you setup the sub-stream to be 640x360@20fps. If you can configure your main-stream to this temporarily then you would see if using auto_host works for RTMP with these settings.

At some point also I should really make the resolution and framerate support better and automatically provide conversion when needed, even if the auto_host route is taken...

Let me know what you think of the above. I can make the code changes if you think it makes sense and looks like it will work for you...
