Microsoft Windows as WFD_Sink - fail #471

Closed OliveiraICTS closed 1 year ago

OliveiraICTS commented 1 year ago

Hi, I´ve added a file .miraclecast at root directory with extentions example existing on /res/sinkctl.protocol-extension.example. I used Log Level 7 during this procedores with log file in PDF format is attached here.

Seen the log, it was possible to see the RTSP sequences M1 to M7 working propperly and M16(Keepalive). By the way after reach M7 Miraclecast detected a fault and disconnected from WFD_Source - Microsoft windows.

Can you see wat was going on?

new logs with --log-date-time are easier to follow. Please provide as separate files

Okay

OliveiraICTS commented 1 year ago

miraclecast performs a mirroring for few time and crashed.

To make it works i changed the .miraclecast config file adding missing Windows required parameters by moving wfd_video_formats to wfd2_video_formats because it was wrong and added new wfd_video_formats according with [MS-WFDPE].pdf Microsoft specification. the .miracast config file mecomes like bellow:

albfan commented 1 year ago

what means crash? do you have a debug session or logs to check what's going on?

OliveiraICTS commented 1 year ago

Log_Miraclecast_20230108_1540.txt This is the log you asked to attach.

albfan commented 1 year ago

I was able to reproduce locally:

free(): invalid pointer

It takes a lot to start streaming so now with --log-date-time we can check what time is spent on

albfan commented 1 year ago

here is the bt:
