vlc commad line screenshot

[DCT]

Hi!

Can I use vlc to take screenshot in cli mode from multicast tv?

It's need to create single picture, web, preview in batch mode without X display.

Help me please.

you have to play with the image video ouput. Something like this should kind of work (untested)

Code: Select all

vlc -V=image --image-out-ratio 20 --image-out-format=png --stop-time=10 <input>

Hi,

is this documented somewhere?
I had a look in the documentation, but wasn't able to find -V.
Tipps, where to look, are welcome.

Regards

run vlc -H --advanced --long-help and it will create a file called vlc-log.txt with all the command line switches.

Thanks.. but small correction:

vlc -vvv --vout=image --image-out-prefix img --image-out-ratio 20 --image-out-format png --stop-time=10

Tested

-vvv may be drop

thx, but this somehow gives me the following error:

Code: Select all

[00000230] main encoder error: no suitable encoder module for fourcc `png '. VLC probably does not support this image format. [00000235] main encoder error: no suitable encoder module for fourcc `png '. VLC probably does not support this image format. [00000236] main encoder error: no suitable encoder module for fourcc `png '. VLC probably does not support this image format.

it creates files with the size of zero bytes. obviosly vlc cannot encode png files, does anyone know, how i could get vlc to encode pngs?

[dionoea]

try jpeg instead (for the --image-out-format option). (btw, which version of VLC are you using ? what OS ?)

[clemens]

it doesnt matter, what output format is choose, the error stays the same, (png encoder not found).
