Description

Goal: Capture webcam video with direct show in Windows 10 Anniversary Edition

Problem: ffmpeg crashes

Command Line:

ffmpeg.exe -f dshow -i video="Logitech HD Webcam C310" test.mp4

Repro:

1) Requires Windows 10 Anniversary edition (http://go.microsoft.com/fwlink/?LinkID=823759) as there seems to have been (breaking) changes to direct show behaviour. Prior to this edition, the command is successful.

2) Run the above command line (replacing the name of the webcam with one appropriate for your system). I have tested this with: Logitech C170, C310 and C615; MS LifeCam CinemaHD and HD-3000; and the integrated camera on my laptop.

3) The camera light will turn on briefly and then ffmpeg will crash. This has occurred for me with my custom-built ffmpeg and the latest Zeranoe build (https://ffmpeg.zeranoe.com/builds/win64/static/ffmpeg-20160811-b83d907-win64-static.zip)

gdb output

The full gdb output is below. I believe it suggests a failure with a direct show call, which seems backed up by the internet being of the opinion that microsoft made at least one breaking change in direct show with this update (https://social.msdn.microsoft.com/Forums/windowsdesktop/en-US/9d6a8704-764f-46df-a41c-8e9d84f7f0f3/mjpg-encoded-media-type-is-not-available-for-usbuvc-webcameras-after-windows-10-version-1607-os?forum=mediafoundationdevelopment)

I obtained this by running the application through cygwin. I will attach the build script I used to build it in cygwin (with gcc, wget, gdb, git, and https://github.com/transcode-open/apt-cyg installed).

Keywords: crash added; webcam windows anniversary removed

Am I correct that the crash also happens if you don't provide an output file name?

comment:2 by Carl Eugen Hoyos, 8 years ago

And just to make sure please recompile with ./configure && make ffmpeg.exe.

Replying to cehoyos:

Yes, you are correct. I hadn't considered doing that, but I just tried it and the crash occurs without the output file name.

So I tried to do ./configure followed by make ffmpeg.exe, but the compilation failed. I can provide the output from the attempt (and the later successful one) if desired, but I think maybe it was just an issue with not specifying cross-compilation. Unsure. Certainly not my area of expertise.

I then tried what seemed like a reasonably minimal configure with cross compilation

./configure --enable-gpl --enable-version3 --arch=x86_64 --target-os=mingw32 --extra-ldflags=-static --cross-prefix=x86_64-w64-mingw32-

followed by

make ffmpeg.exe

and this produced the same failure.

Edited: stack trace removed as see comment 7 indicating gdb was breaking on a memory warning rather than on the crash so the output was meaningless for this issue.

I would consider a failure in native default compilation much more important for us than an apparent change in an external interface.

Well, I'm compiling it in cygwin, not linux (based off https://trac.ffmpeg.org/wiki/CompilationGuide/CrossCompilingForWindows). So I imagine that's why there's a problem with a 0 argument configure. But I consider myself a neophyte with respect to ffmpeg compilation so I could certainly be wrong.

I have attached the console output from running ./configure and make ffmpeg.exe in cygwin so you can see for yourself.

comment:7 by Colin Davidson, 8 years ago

It has been pointed out to me that I performed the gdb debugging incorrectly or at least that I was debugging the wrong point in the stack because apparently gdb was breaking on a memory warning rather than on the crash (this is my first time using gdb and I was blissfully unaware of this fact).

I ran it again, but this time ran handle SIGTRAP nostop as the first line in gdb prior to executing the ffmpeg command. I have included the updated output below. I would update the original post, but there doesn't seem to be a way to modify the text of the report.

Replying to cehoyos:

Outputs attached. Looks like patch 2 avoided the warning for the compilation of the random seed file.

Replying to cehoyos:

I have updated the output from patch 1 and it too seems to work. I have also run make ffmpeg.exe on the patch2 branch and it completes without error.

However, when built in this manner, and trying to run the command at issue

./ffmpeg.exe -f dshow -i video="Logitech HD Webcam C310"

You get

$ ./ffmpeg.exe -f dshow -i video="Logitech HD Webcam C310"

which I'd imagine is caused by it not being cross-compiled and thus it isn't possible to diagnose the filed issue using this build.

comment:12 by Carl Eugen Hoyos, 8 years ago

Please find the and post the relevant part of config.log starting with check_type dshow.h IBaseFilter

comment:13 by Colin Davidson, 8 years ago

So, I've made a best guess as to what the relevant part of the config log is. Also, you said "post" so I'm assuming you want it in a code block (despite the length of at least one of them) rather than an attachment.

By the way, for what's it worth, Microsoft seems to have made changes in the update in question to allow multiple applications to access the webcam at the same time. Part of this change seems to involve svchost.exe accessing the webcam and acting as a proxy in some way. At least that's my best guess based on seen behaviour (for instance, the protection software now notes access to the webcam by svchost rather that ffmpeg, skype, or flash when those applications access it).

I applied a fix for Cygwin default compilation as 79dc94a63b30369e39792e81cb032f2cf40539b4, thank you for testing! I don't know why Cygwin dshow compilation fails (and imo, this should absolutely be fixed) but this likely has a lower priority;-(

Concerning your original issue: Iiuc, your analysis indicates a problem that should not be fixed within FFmpeg but please contact Roger D. Pack if you need help with dshow within FFmpeg.

for followers, here is a partial workaround fix: https://gist.github.com/rdp/b3d080d126b341f08b112f06489a6b25
It works for any media type *except* bg24 seemingly. Hope to figure out more soon :)

Resolution: fixed
Status: newclosed

This appears to have been fixed.

I cannot reproduce the issue with a Logitech C920 webcam on Windows 10.0.15063 with the latest FFmpeg git.
