Fixed bug #798
kty@lavabit.com 2009-09-19 14:19:04 PDT
The stable release of SDL 1.2.13 for BeOS/Haiku has a bug in
BE_FindClosestFSMode that causes it to sometimes not select the best mode when
going fullscreen. There are in fact two bugs in the implementation but I will
not go into specifics because there is already a patch for it in the developer
SVN 1.3. However I am still reporting it because I believe the following code
is a better patch for the issue. The current implementation on SVN only works
if it is able to find an exact match for the requested mode. However, by
scanning from lowest-to-highest resolution instead of highest-to-lowest, one
can find the best mode at all times

| 10 .PP | |
| 11 Before an \fI\fBSDL_AudioCVT\fR\fR structure can be used to convert audio data it must be initialized with source and destination information\&. | |
| 12 .PP | |
| 13 \fBsrc_format\fR and \fBdst_format\fR are the source and destination format of the conversion\&. (For information on audio formats see \fI\fB SDL_AudioSpec\fR\fR)\&. \fBsrc_channels\fR and \fBdst_channels\fR are the number of channels in the source and destination formats\&. Finally, \fBsrc_rate\fR and \fBdst_rate\fR are the frequency or samples-per-second of the source and destination formats\&. Once again, see \fI\fBSDL_AudioSpec\fR\fR\&. | |
