Calling Open Source to open a Streaming Media Source causes a freeze to occur on Android when it is called. This does not happen on all devices. When testing this issue, I reproduced this issue on a Nexus 5 but was not able to reproduce on a Pixel XL.
The user who reported this issue also mentioned that this occurred on Galaxy S9, Vivo V11, Oculus Go, and some Redmi phones (no specific models given), but this has not been confirmed locally.
This occurred in 4.20
