Hello everyone
I have a problem with VLC filter canvas.
I have a playlist with different video format.
Example: video1 = 480x360
video2 = 1024x720
video3 = 1920x108
I want to see the same format 720x576 aspect 16: 9

My final video output format strange, deformed.
Can I use canvas filter to solve my problem? Or I have to make another filter?

no one can help me.
I have to add a logo, which must always have the same size. and run the playlist with different video format.

I do not have good experiences with canvas video filter, too. Perhaps it is buggy. You could file a bug report @ https://trac.videolan.org/vlc and provide some information about behaviour of the filter with different input formats.

hello, thank you for responding. I do not know much VLC. I am studying.
Now, I'm using version 2.2.0 testing VLC

The canvas now works. The odd thing to me is that the display is always the size of the source file.
Example: open a file 1920x1080 canvas 480x380. I see low quality, canvas works! VLC opens display large 1920x1080. I want the display is 480x380. Do not know if you understood, complicated problem.
My problem is to insert a logo that should always remain the same size with any video size.
sorry for my english

hello mederi. you can report this anomaly? in @ https://trac.videolan.org/vlc
I do not know how to do, my English is bad
*************************************************************
I am using canvas feature in VLC 2.1.5 for win32. My system Win7 -32bit.
example:
vlc -vvv c:\film\01\01.mp4 --video-filter Canvas video filter --canvas-width=720 --canvas-height=576 --canvas-aspect=16:9 --canvas-padd

01.mp4 is 480x360, canvas transforms video abnormally.
if
01.mp4 is 1920x1080, canvas transforms video abnormally.
-------------------------------------------------- ---
I tried vlc-2.2.0-rc2-20141206-1232
vlc -vvv c:\film\01\01.mp4 --video-filter Canvas video filter --canvas-width=720 --canvas-height=576 --canvas-aspect=16:9 --canvas-padd

01.mp4 is 480x360, video canvas function enlarge 720x576 ok!
size = 480x360 diplay VLC, strange behavior. must be like the video, 720x576.
Because if I apply a logo, I can move it in 480x360 and not 720x576.

01.mp4 is 1920x1080, Canvas function reduces size 720x576 and cut part of the video.
if I apply logo, I can move inside VLC display in 1920x1080 and not only in 720x576.

The function canvas must resize the video display and VLC to the desired size?
So I can play playlists with videos of different size to the same size,
and apply logos remain the same size in all videos.
