Rotate output stream

[Ares]

Hi,

I'm using VLC 0.9.2 installed as a windows service. I have configured in VLM few streams like:

new Cam1 broadcast enabled
setup Cam1 input "http://user:pass@xx.xx.xx.xx/ipcam/sjpeg.cgi"
setup Cam1 output #transcode{vcodec=WMV2,vb=1024,scale=1}:std{access=mmsh,mux=asf,dst=xx.xx.xx.xx:8081}
control Cam1 play

Everything ok except one thing: I need to rotate one of the streams.

I can play (localy) starting from cli:
vlc http://user:pass@xx.xx.xx.xx/ipcam/sjpeg.cgi --vout-filter=transform --transform-type=vflip --transform-type=hflip
and the camera is rotated, but I need that output stream rotated.

I think I'm doing some mistakes on the output syntax, I tried in many ways to add "--vout-filter=transform --transform-type=vflip --transform-type=hflip" but without success.

Please advise!

Thanks

Code: Select all

--vout-filter=transform --transform-type=180

Hi Remi,

I tried :

setup Cam1 output #transcode{vcodec=WMV2,vb=1024,scale=1}:std{access=mmsh,mux=asf,dst=xx.xx.xx.xx:8081}--vout-filter=transform --transform-type=180

but isn't working, I receive an error (syntax incorrect).

Thank you for help!

Is there any work done by developers in addressing this issue ? I think we need a filter in the sout to transform the video for streaming.

OK, I figured it out with some googling. I can rotate the image in sout, but the image is clipped when I play in vlc. Here is what I used to sout and transcode.

Code: Select all

vlc -I dummy somefile.mpg --rotate-angle=90 --sout "#transcode{ deinterlace, fps=18, vb=192, vcodec=x264, acodec=mp3, ab=16, channels=2,deinterlace,vfilter=rotate,scale=.5}:std{access=mmsh,mux=ts,dst=0.0.0.0:8888}" vlc://quit

When I see the streamed output, the picture is flipped 90 deg , but the top and bottom (original left and right) are now clipped.

Here is my vlc flags etc

Code: Select all

After 2 days of searching solution for exporting live stream from my Axis camera into a file with 180 degrees rotation I finally found it.

Originally I had this:
":sout=#transcode{vcodec=h264,acodec=none}:file{dst='<output_file_path>'}"
That works fine but I got video upside down.

Then I tried this:
":sout=#transcode{vcodec=h264,acodec=none,vfilter=rotate{angle=180}}:file{dst='<output_file_path>'}"
Rotation worked but output video was 16x16 size.

After this article "http://www.wintips.org/how-to-rotate-an ... ia-player/" and some digging in VLC player logs (vlc.exe --verbose=2 --file-logging --logfile=vlc-log.txt) I came up with this:
":sout=#transcode{vcodec=h264,width=1280,height=720,vfilter=rotate{angle=180},acodec=none}:file{dst='<output_file_path>'}"
Width and Height parameters prevent scaling output video into 16x16.

PS: I am using VLC 2.1.3
PPS: "transform{type=180}" doesn't work in some reason

transform does not work with all types of inputs.

I came up with this:
":sout=#transcode{vcodec=h264,width=1280,height=720,vfilter=rotate{angle=180},acodec=none}:file{dst='<output_file_path>'}"

Do you know how can I apply your solution to a VB Net project? I'm a noob with VLC and I saw that there is no answer for other post about the same issue.
