encoder problem or hardware problem #3120

fuch123 · 2022-03-16T13:53:56Z

[ yes ] I have read the FAQ.
[ yes ] I have searched in existing issues.

Environment

OS: [Raspbian Linux 11 (Debian)]
scrcpy version: [1.23(the newest one)]
installation method: [manual build]
device model: xiaomi 10S
Android version: [12]

Describe the bug
I installed raspbian Linux on Microsoft's surfacert
Then I want to use surfacert as a touch screen
Surfacert is an arm-32-bit NVIDIA processor
Connect my Xiaomi 10s mobile phone (Android 12)
Illegal command error while executing command
After reading the FAQ and other issues, they failed to solve the problem
I tried scrcpy - m1024, -m800, -m600, but all failed
But it's strange that this mobile phone can work normally on windows 10-64 bit system through scrcpy-1.23
The problem should be located on the surfacert device. It seems that it should be the problem of the encoder
I don't know if it can be solved. I hereby ask a question.

Illegal instruction

This is a problem on the client side, it looks like a build problem.

Could you build with sanitizer enabled please?

meson d -Db_sanitize=address,undefined
ninja -Cd
./run d

(or run in gdb to know where this "illegal instruction" happens)

fuch123 · 2022-03-16T16:14:17Z

Because I don't want to recompile the server, I compiled it with reference to common steps and option 2 on the website
However, an error occurred, as follows:

Sorry, I don't quite understand the method you gave. Can you be more detailed.
Thanks a lot.

rom1v · 2022-03-16T16:26:35Z

meson d -Db_sanitize=address,undefined -Dprebuilt_server=/home/pi/scrcpy/scrcpy-server

This is correct 👍

==9417==ASan runtime does not come first in initial library list; you should either link runtime to your application or manually preload it with LD_PRELOAD.

You should not have this error: google/sanitizers#796

Maybe try building with clang instead (even if it should work out-of-the-box with gcc):

rm -rf d
export CC=clang
meson d -Db_sanitize=address,undefined -Dprebuilt_server=/home/pi/scrcpy/scrcpy-server
ninja -Cd
./run d

Otherwise, run it from gdb, you might get the backtrace:

export SCRCPY_SERVER_PATH=d/server/scrcpy-server
gdb d/app/scrcpy

Then, in gdb:

(gdb) r

And when it crashes with "illegal instruction":

(gdb) bt

It should print the backtrace. Paste it here.

rom1v · 2022-03-16T16:27:34Z

You could also try to remove undefined:

meson d -Db_sanitize=address -Dprebuilt_server=/home/pi/scrcpy/scrcpy-server

Hi
I tried three methods you provided, but none of them succeeded.

(1) Common steps, with export CC = Lang, the results are as follows:

Let me remind again that my Linux host is the raspbian Linux system of arm32, Is the problem still due to the hardware codec

I feel that test (3) can reflect the problem and help analyze it. How to solve it? Thanks a lot!

Hello, moderator.

After that, I did several experiments and installed clang. The compilation was successful, but there was still an illegal instruction error when running. The situation is as follows:

Looks like an issue in your ffmpeg build (libavcodec).

fuch123 · 2022-03-25T08:52:57Z

Is there any solution? Those library files are installed through apt.

Or guide me to compile those ffmpeg library files on my own machine.
