Bug 20187 – vcr captures video upside down

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Dave 2003-04-29 17:20:29 UTC]

Installed the latest media-video/vcr package (for my gentoo-pvr), and it 
worked beautifully, except the video was upside down.  I searched the web and 
found entries for a similar bug being fixed in Debian, but nothing about 
gentoo.  So, I browsed the cvs and found references to a "flipped vcr fix" 
that was put into the package and then subsequently removed.  So I sent an 
email to the fixer who had provided the patch for debian and he told me that I 
had to do the following in capproc.cc

 // RO patch to fix mirroring
 memcpy(tmpframe + i*c_bpl, z + (i)* o_bpl + o_x_off, c_bpl);
 //memcpy(tmpframe + i*c_bpl, z + (o_y_end -i -1)*o_bpl + o_x_off,c_bpl);

So I did an emerge unpack, and then modified the source, and then did an 
emerge-compile, and -install, and -qmerge and it works great!

Apparently the old code was there to deal with a weird issue in avifile which 
has subsequently been fixed.

It would be wonderful to see this in the vcr package.


Reproducible: Always
Steps to Reproduce:
1.  Build a box with a bttv card (Mine was an ATI TV-Wonder)
2.  Install gentoo
3.  Install vcr
4.  Try to record some TV
Actual Results:  
Video upside down

Expected Results:  
Video rightside up

do you know which version of avifile you are using?

[Comment 3 Alastair Tse (RETIRED) 2003-05-04 20:31:50 UTC]

bug reporter? 

i don't have a tv tuner anymore, so i can't test it. if you could let me know which version of avifile you have installed, i can make sure since which version this was fixed.
