Scrcpy: Error in Windows 10: Assertion len >= s->orig_buffer_size failed at src/libavformat/aviobuf.c:581

I downloaded the prebuilt x64 version.
When I try to execute it, I get the following error:

PS D:\desc\scrcpy-win64> ./scrcpy.exe

Every time?

It seems the connection is closed by the server. What is your Android version?

[ownchoice]

Yes, every time, even with the 32-bit version.
I have Android 5.0.2.

The server may not connect to the client (it fails only on write, not on connect, due to the adb tunnel). Maybe you have a firewall or something which blocks the connection?

LG-H778 Android 5.0.2 also had the error.

Ah but wait, could you test the master version, this could be the same issue as https://github.com/Genymobile/scrcpy/issues/291 on 5.0.1, which has been fixed by https://github.com/Genymobile/scrcpy/commit/b882322f7371b16acd53677c4a3adbaaed0aef77.

See https://github.com/Genymobile/scrcpy/issues/291#issuecomment-427906676.
(download the file, rename it scrcpy-server.jar and replace the existing one)

Yes, it did fix it! Thanks for the help.
