Description

Hi,

I'm having issues with dshow, where some of the device configurations it reports appear to be invalid. When using the dshow list_options option it prints all the available configurations for the device:

C:\FFmpeg>ffmpeg -f dshow -list_options true -i video="HD Webcam C525"

It's the same for most mjpeg configurations on the list. Sometimes it doesn't show this error, but simply gets stuck. Here's an example of a configuration that finally works.

I suspect it may be because dshow is using deprecated Windows structs. Most of the fields it uses in VIDEO_STREAM_CONFIG_CAPS are deprecated as listed here: http://msdn.microsoft.com/en-us/library/windows/desktop/dd407352%28v=vs.85%29.aspx

Do you mean this one: "Logitech HD Webcam C525 720P HD Auto Focus"?
It is officially declared as capable of 1280x720 resolution only, so most probably the behaviour described in the ticket is "as designed".
Are you able to capture 1920x1080 by means of other software?

comment:2 Changed 5 years ago by MattE

I didn't try with other software, but I don't really care about that part since 1280x720 is good enough for me anyway. The issue is that dshow reports all these configurations which cannot work, e.g. 1920x1080 in this case.

I thought this was caused by using the deprecated fields, and if we moved to current MS methods of getting this info the information returned might be more accurate.

comment:3 Changed 5 years ago by domingo

The issue is not caused by deprecated fields because 1280x960 connection works fine.

comment:4 Changed 5 years ago by MattE

What else is causing it to report these incorrect configs? I imagine there's a better way of finding the supported configs that is more accurate?

Btw, it does support 1920x1080, just not when specifying -vcodec mjpec:

ffmpeg just reports media types returned by webcam driver, which seems to output static tables. However webcam driver checks resolution and framerate upon connection and rejects unsupported ones. Anyway it is webcam software issue, not ffmpeg.

Btw, regarding resolution - pay attention on framerate. 1920x1080 is not supported at full 30 fps framerate. And again, webcam driver behaviour could heavily depend on AUTOFOCUS setting. Typically resolutions get restricted when autofocus is enabled.

Just happened to get a Logitech HD Webcam C525 yesterday and I enumerate the sizes outside of ffmpeg and then feed those sizes to ffmpeg which works. The lowest supported size I see is 160x120 and highest is 1600x896 and they all work. Tried another program and listed the same range. Don't know where your higher resolutions are coming from unless driver you have installed is confused somehow. More than likely 1600x896 will work for you though. You say 1920x1080 works then with yuyv422 ?

The name of my logitech C525 is "Logitech HD Webcam C525" and with that name got same size range with ffplay as I mentioned in comment6.

Mine is also the Logitech C525. I'll try it on another computer to see what it reports. But yes, I was able to get 1920x1080 at 5fps (I didn't actually check the size that dshow returned, but ffplay played when I specified this size). Just try ffplay -f dshow -video_size 1920x1080 -framerate 5 -i video="HD Webcam C525".

Maybe it's the driver that's messed up, still we probably should not be using deprecated things.

What other software did you use to enumerate the possible configs? I couldn't find a free software that will do that.

I just tried it on a different win7 64 bit computer and got identical results as posted. Did you try it on 64 bit? Maybe the webcams have different hardware revision or something.

comment:11 Changed 5 years ago by DonMoir

I used iSpy which is camera program and windows movie maker to get list and all same with mentioned resolutions. Also my internal resolution enumerator using dshow (not ffmpeg) comes up with same list.

When I try to list_options via ffplay I must use video="Logitech HD Webcam C525". Using just "HD Webcam C525" errors out saying device not found for me. Using XP now but can try Windows7 64bit later. Try using the full name "Logitech HD Webcam C525" and see what you get with that. The name difference is probably a clue though.

I tried with ffplay and 1920x1080 and said could not set video option.

Got same results name, resolutions, and everything on Win7 as you. Will look some more later.

Ok, so it was a driver issue.

Yesterday I got this driver update through windows update (http://catalog.update.microsoft.com/v7/site/ScopedViewInline.aspx?updateid=876bae8d-4a60-4423-a1d9-0d983b2b1e3a) and that made it work. This update is from 2012, so I don't know why I didn't get it before (maybe they read ffmpeg tickets...). It now reports only correct configurations and it changed the device name to "Logitech HD Webcam C525" like you had.

Here's what it shows:

C:\FFmpeg>ffmpeg -f dshow -list_options true -i video="Logitech HD Webcam C525"

Also, it does work at full 30fps at 1600x960 and the camera itself seems to have improved a bit with regards to frame rate.

Anyway, I don't seem to have the option to close the ticket. Please close it.
