Bad Framerate

[eliteSchwein]

Describe the bug
I have only 3 FPS or so

To Reproduce
Open a HD 30fps Stream

Expected behavior
Run at 30fps

Environment

• Device: MiMix
• OS: 11
• MjpegView version 1.0.9

Additional context

Written in Kotlin but the behavior should be the same in Java

val camViewer: MjpegView = root.findViewById(R.id.webcam_stream)
camViewer.mode = MjpegView.MODE_FIT_WIDTH
camViewer.setUrl(printerData.getString("webcamurl"))
camViewer.isRecycleBitmap = true
camViewer.startStream()

Can you try using this streaming URL https://server.hafka.co/mjpeg and confirm that the issue is still stand?

lower res helps a bit, but i have a HD stream or FHD Stream

[perthcpe23]

Sorry to ask but is it your internet connection speed? I try mentioned URL above and it works fine, I got 30 fps (judging by eyes).

i have 160mbit, the mjpeg is smooth in browser but not app, i tried it with 640*480 aswell...

Is your streaming server publicly accessible? I tried mentioned URL and it works fine on my Sony 5 II. There are too many factors to start discuss one-by-one here. I guess it may have something to do with streaming content your server generates which is supported by browser but, not this library (yet).

i use a local url, with webview it works fine

[perthcpe23]

So, a connection speed is less likely an issue here. Can you run this command for a few seconds and send me dump.bin file? I suspect the issue is with stream content.

curl --output dump.bin "<YOUR-MJPEG-URL>"

with https://server.hafka.co/mjpeg/ it runs smooth, but again thats low res

[perthcpe23]

I see. Let me try FHD version of https://server.hafka.co/mjpeg/. I have never worked with FHD mjpeg.

[eliteSchwein]

i use also 25mbit

[perthcpe23]

I changed https://server.hafka.co/mjpeg/ to FHD and fps indeed drops. Now that I can reproduce the issue, I will continue investigating the issue.

[eliteSchwein]

Yeah i can short your search, its drawBitmap... I tried it with opengl because of that but i domt understand how i can use opengl, maybe it helps you?

Thanks, wow that is a whole new level of rendering.

Reduce video quality did help https://server.hafka.co/mjpeg?type=fhd_low_quality compare to original quality https://server.hafka.co/mjpeg?type=fhd_hi_quality.
