[vlc] Problems with YUV images and mosaic mode

[Iván Sánchez Ortega]

Hi,

I'm trying to set up a mosaic video, as in the "Mosaic" page of the VideoLan 
wiki (http://wiki.videolan.org/index.php/Mosaic).

However, I get stuck on step 2, when preparing a YUV image as the background 
for the mosaic composing.

As per the wiki page, I had to make a .uyvy image. Not hard at all: get the 
gimp ready, draw a test image of the required size (in my case, 800x600), 
save it, use ImageMagick's "convert" to get the .uyvy file.

Now, that .uyvy file will be displayed using ImageMagick's "display", but if I 
try to view it using VLC 0.8.2-test3 (Yes, I know, I'll compile 0.8.2 final 
through the day), mimicking the example of the wiki:

[mpeg2video @ 0xb7f20008]only YUV420 is supported
[00000219] stream_out_switcher private error: cannot open encoder

Hhhhmmm, that's not good. Let's try convering the image to .yuv and playing 
it:

[00000219] stream_out_switcher private error: premature end of file foobar.yuv
[00000218] main stream output error: stream chained failed for 
`switcher:display'


At this point, I'm really lost. Any ideas? Any help will be greatly 
appreciated.
