Rotate and Crop stream from Batch file?

[blzbubb]

Hi,

All i'm trying to do is receive an rtsp video stream rotate it and use --crop-geometry to trim out the bits i dont want. Unfortunately it needs to be an uneven crop rather than just a ratio. Ratio crops seem to work fine.

This is what is in my batch file:

Code: Select all

vlc rtsp://192.168.0.70:8554/stream :rtsp-caching=80 :vout-filter=transform,crop :transform-type=90 :crop-geometry="768x565+0+10"

This results in the stream opening correctly and rotating but no crop.
I also tried eliminating the rotate to help debuging:

Code: Select all

vlc rtsp://192.168.0.70:8554/stream :rtsp-caching=80 --vout-filter=crop --crop-geometry="768x565+0+0"

This results in a window the correct size but just blackness with no stream.

I'm hoping it's a syntax error

Any help would be great!

Should be fixed in 1.2.0/2.0.0 release

Hi, Thanks for the info.

I just tried with the latest build.
Although I can get the result i'm after via the GUI, the command line statements above dont seem to work.
The rotate does but not the crop.

Is there something fundamentally wrong with the syntax?

[VLC_help]

I don't remember any crop related changes recently, so it should work like that. If you open Tools -> Messages (set Verbosity to 2) it will complain if something is wrong.

[blzbubb]

No errors seen but the crop isn't working.

The rotate does though.

[VLC_help]

Does vlc --list actually show the crop filter? In my builds there is only

Code: Select all

croppadd Video scaling filter

[blzbubb]

In the 2.1.0 build I have cropadd and transform but no crop.

In the 1.1.11 build I dont see crop or cropadd but transform is there.

This is driving me nuts now!

Any help is greatly appreciated.

Use cropadd

[blzbubb]

Can you give me an example of how cropadd would work with the rotate?

I have tried it a few times with no luck.

[VLC_help]

Croppadd works like

Code: Select all

vlc --video-filter=croppadd --croppadd-croptop=100 video.mp4

The Cropadd options in "Preferences / Video / Filters" do nothing.
The check box to enable Cropadd seems to be missing.
More Oddity: the filters are not in alphabetical order... searching the list is quite unpleasant.

But the command line mentioned earlier works to split a 3d movie so it's watchable 2d:
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" --video-filter=croppadd --croppadd-cropright=1200 "1080movie.mkv"

Thanks.

to set-up the filter: Preferences > (Show settings - All) > Video > Filters > Cropadd
to turn it on: Preferences > (Show settings - All) > Video > Filters: Video scaling filter
Be careful, because there are 2 "Video scaling filter" in the list of "Video filter module"!

Yes, it really is. Using descriptors instead of direct filter names in the list of filters, "Video scaling filter" instead of "Cropadd" like in the tree menu on the right side, is really a stupid idea.
