After android upgrading, scrcpy stops working

[amosbird]

it never pops out the phone screen, only showing

/usr/share/scrcpy/scrcpy-server.jar: 1 file pushed. 1.2 MB/s (18802 bytes in 0.015s)
INFO: Initial texture: 2160x1080

on the terminal.

Is there anything I can do to debug this?

[rom1v]

adb logcat

And you could try a lower definition:

scrcpy -m1024

[amosbird]

adb logcat doesn't generate anything and scrcpy -m1024 or lower doesn't work either

[amosbird]

using the master commit, I saw ^CERROR: Could not open video stream after hitting ctrl-c . Is this related? #291

[rom1v]

adb logcat doesn't generate anything

At all? Then your device has a problem.

What about adb shell or adb devices?

[amosbird]

adb shell and adb devices work fine.

At all?

It has some outputs but doesn't generate anything new after running scrcpy

[amosbird]

Hmm, found something suspious. /data/local/tmp/scrcpy-server.jar gets removed after I saw INFO: Initial texture: 2160x1080

[amosbird]

manually running the server

 ❯ adb shell

That's expected: https://blog.rom1v.com/2018/03/introducing-scrcpy/#clean-up-the-device

[amosbird]

this adb exec-out screenrecord --output-format=h264 - | vlc - --demux h264 works as expected

[amosbird]

@rom1v I've made some progress.

1. using Uint32 window_flags = SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE; I found that the input events work just fine

2. dumping the error message of avformat_open_input via LOGE(av_err2str(rc)); I get Invalid data found when processing input

[rom1v]

Is there anything I can do to debug this?

You can use gdb:

export SCRCPY_SERVER_PATH=x/server/scrcpy-server.jar
gdb x/app/scrcpy

(if x is your builddir)

Put a breakpoint on scrcpy():

(gdb) b scrcpy

and run:

(gdb) r

Then run line-by-line to know where the client "waits":

(gdb) n

EDIT:

using Uint32 window_flags = SDL_WINDOW_SHOWN | SDL_WINDOW_RESIZABLE; I found that the input events work just fine

Ah, so now it starts again?

[amosbird]

Ah, so now it starts again?

Nope, only the input events work, no video stream

[amosbird]

Then run line-by-line to know where the client "waits":

The error obviously comes from avformat_open_input call which returns : Invalid data found when processing input

[amosbird]

@rom1v the client actually waits at avformat_open_input and the syscall is recv

Another progress, android server hangs at https://github.com/Genymobile/scrcpy/blob/v1.5/server/src/main/java/com/genymobile/scrcpy/ScreenEncoder.java#L92

[amosbird]

It seems there is no input for codec after setDisplaySurface(display, surface, contentRect, videoRect);

[rom1v]

After android upgrading

You upgraded from which version to which version, on which device?

[amosbird]

I just noticed that the Android version doesn't change. I've updated the flyme rom from 6.3.2.2A to 7.1.0.0A. The device is Meizu Meilan-E3. There are related issues #151 and #240

However it used to work. And it never throws any exceptions after upgrading.

[amosbird]

The only log entry after doing CLASSPATH=/data/local/tmp/scrcpy-server.jar app_process / com.genymobile.scrcpy.Server 0 8000000 false '' false is

11-25 18:28:51.064  3330  3330 I Radio-JNI: register_android_hardware_Radio DONE
11-25 18:28:51.085  3330  3348 E SchedPolicy: open of /dev/cpuctl/bg_non_interactive/tasks failed: No such file or directory

Is there anything I can do to debug the issue of setDisplaySurface?
