[BUG]: Crash on Android devices when streaming to Amazon IVS Server
Package version
2.4.0-exp.9
Environment
* OS: Android
* Device: Reproducible both on Samsung Galaxy S8 & Oculus Quest 1
* Unity version: 2021.3.3f1
* Codec: H264
Steps To Reproduce
Amazon recently added support to stream to Amazon IVS (Interactive Video Service) directly using WebRTC, which is the same infrastructure used by Twitch. This opens up the opportunity to stream from within a Unity application directly to Twitch (at least on Android. On Windows, it seems that the required H264 profile is not supported somehow).
This setup works in principle, but the application crashes frequently.
I understand that to reproduce, you would need to have access to the code I'm using to set up the connection with a Twitch Stream. I'd be happy to share it privately with Unity staff if necessary.
Current Behavior
The streaming does work at times, but there are frequent crashes. Some crashes appear right after the application starts, some only after several seconds or even minutes. The recent changes in 2.4.0-exp.9 didn't fix the issue for me. The issue seems to appear irrespective of whether OpenGLES3 or Vulkan is used, and whether 'Optimized Frame Pacing' is enabled or not.
Here's an excerpt from the Android log from a Galaxy S8 device:

Expected Behavior
A stable stream without crashes.
Anything else?
No response
Thanks for your answer! Unfortunately, I can't test either of those for other reasons.
Windows: The issue is that the server expects one of the following H264 profiles (I think they use Pion in their WebRTC stack):
- level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=42001f
- level-asymmetry-allowed=1;packetization-mode=0;profile-level-id=42001f
- level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=42e01f
- level-asymmetry-allowed=1;packetization-mode=0;profile-level-id=42e01f
- level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=4d001f
- level-asymmetry-allowed=1;packetization-mode=0;profile-level-id=4d001f
My PC (Nvidia GTX 960) only contains the following profiles when I create a WebRTC Offer:
- implementation_name=NvCodec;level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=420033
- implementation_name=NvCodec;level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=640033
- implementation_name=NvCodec;level-asymmetry-allowed=1;packetization-mode=1;profile-level-id=4d0033
For that reason a WebRTC connection can't be initiated on Windows and will fail already at the signaling stage (this works fine on all Android devices I tested, where profile-level-id=42e01f is supported).
In summary, the sever expects me to use H264 Profile Level 3.1, but the WebRTC package automatically chooses the highest available Profile Level 5.1, (independent of which resolution and bitrate I put into Camera.CaptureStream()). Being able to explicitly choose a lower profile level would fix this, but I guess this is separate issue / feature request.
~~I guess I could use VP9 with a software encoder instead for testing, but from the documentation I do not know how to enable software encoding? There used to be an EncoderType.Software enum to pass to WebRTC.Initialize(), but that seems to have changed?~~ EDIT: It seems the server-side does require H264 and won't work with other codecs, so I'm stuck with using H264.
Mac: I don't have access to a Mac, that I could test this on.
We customise the SDP string when signaling, and we test them with Unity and browsers but not Pion. It is possible that this modification may occurs the crash by the process of SDPs on Pion.
2.4.0-exp.10 has the same issues. I don't think the error happens during signaling. On Android the signaling process is always successful. Even streaming works for a few seconds until the app crashes with the error posted above.
@julienkay Users reported some SoC of Android has crashed here. https://github.com/Unity-Technologies/com.unity.webrtc/issues/437
Do you think this issue is about specific SoCs?
@julienkay
Does the sample PeerConnection scene of the WebRTC package work on your Android device? (using H264 codec)
@karasusan I'm not sure this is a problem with a specific SoC. Quest 1 has a Snapdragon 835, and AFAIK my Galaxy S8 being the EU version means it has an Exynos 9 Octa 8895. So two different SoCs having the same issues.
@kannan-xiao4 The PeerConnection sample seems to work fine on my device. I couldn't reproduce any crashes. (tested with 2.4.0-exp.10)
In case you want to investigate further, I just added both of you to a private repository with code that reproduces the issue.
@julienkay I would be glad if we have the smallest sample to replicate the issue.
I'm not quite sure I understand. Can you elaborate? The repository I Invited you to is the smallest reproducible sample code I can produce: https://github.com/Doji-Technologies/twitch-streaming-unity/invitations

Seems Amazon IVS web broadcast SDK is a WebRTC SFU server, which coverts WebRTC to RTMP or HLS etc.
If you need to debug at the server side, we encorage srs-unity, which is open source, and I would like to help you to finger out the issue.
We build some examples for unity WebRTC to publish stream to WebRTC SFU server, seems works well, so the issue might be introduced from client side or media content.
If you want, you can also find me at discord
@winlinvip Thanks for sharing your great work. I have one question, I would like to know this project works well with the latest version of WebRTC package.

I tested with 2.4.0-exp.11, 3.0.0-pre.1, 3.0.0-pre.2, 3.0.0-pre.3, 3.0.0-pre.4 it works good. Please see environment for detail.
Note: Because 2.4 change the API of camera, which is not compatible, see https://github.com/ossrs/srs-unity/issues/2 and https://github.com/Unity-Technologies/com.unity.webrtc/issues/498
