Problem with too many threads when looping #11336

Closed LQ753799168 closed 10 months ago

LQ753799168 commented 10 months ago

When I play a video on android, if I don't set Loop, then create ExoPlayer: Loader: ProgressiveMediaPeriod thread there would be only one, but if I check the Loop, Will appear many ExoPlayer: Loader: ProgressiveMediaPeriod threads, sometimes as many as 19, could you tell me how to avoid the excessive number of threads created, the number of the number of threads created which parameters related。

Unity version: 2019.4.30f1 AVPro Video version:2.8.5

https://github.com/google/ExoPlayer/assets/35380099/c68c7e8e-f202-4fd6-910b-e6ba88db9f4a

https://github.com/google/ExoPlayer/assets/35380099/23387d2b-114f-4120-8b0d-5532e0ccd8ad

Video 1 will create 5 threads。 Video 2 will create 19 threads

Verification method：

adb shell "ps|grep com.DefaultCompany.AVProDemo"
adb shell cat /proc/pid/status
adb shell ps -t pid

For example

C:\Users\Lenovo>adb shell ps -t 23483
USER      PID   PPID  VSIZE  RSS   WCHAN              PC  NAME
