Subject: wmtv: incorrectly calculates bytes per line
Date: Mon, 09 Apr 2001 21:15:52 +0100
wmtv does not put the tv display in its window on my second head.
According to bttv, wmtv is telling bttv that the display is:
Display at ea800000 is 800 by 600, bytedepth 2, bpl 1600
If I use xawtv, it correctly sets the bpl value:
Display at ea800000 is 800 by 600, bytedepth 2, bpl 1664
wmtv is probably incorrectly assuming width * bytedepth = bpl.

Found the problem, at least this fixes it for me at 1600x1200.

Patch by Yann Vernier <yann@algonet.se>. From [1]:
wmtv failed to read my .wmtvrc (hand written) correctly, I tracked it
down to incorrect memory management (sizeof() instead of strlen()).
The code was so bad that I chose to rewrite it to a simpler version,
patch below.
Other bugs fixed include some of the memory leaks (which are quite
numerous) and truncating the .wmtvrc when writing to it.
Cosmetic changes include keeping comments in .wmtvrc, C++-style
comments changed to C style, and numbering channels from 1.

This fixes the package-contains-timestamped-gzip warning given by Lintian
for the Debian package. (This warning is really unnecessary, as its purpose
it to check for reproducible builds and the fonts are not compressed at
build time, but I see no harm in removing these timestamps.)
In the README it is said to run ./configure but there's no such script in the
tarball. I wrote instructions to generate a ./configure with libtool and autotools.
- More logical relationship between volume level and bar length
- No unnecessary drawing
- Volume bar shrinks properly even when volume is lowered very quickly
Otherwise, we get the following warning during build.
wmload.c: In function ‘GetLoad’:
wmload.c:523:10: warning: incompatible implicit declaration of built-in function ‘rint’
*usr = rint(Maximum * (float)(*usr) /total);

In particular, if HOME is undefined, then a segmentation fault will occur.
Also, if HOME is at least 245 characters, then a buffer overflow will occur.
We check for these conditions and exit with an error message instead.
