xawtv & mmap

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi all,

I recently noticed that xawtv sometimes tries to mmap() buffers for
display. If you resize the video window, it apparently re-requests and
re-mmap()s the buffers, however, it does this without munmap()ping the
old buffers. My drivers gives errors 'buffers already allocated' errors.
Is this indeed true for xawtv-3.78? If so, would a patch to fix this be
appreciated (i.e., is this the intended behaviour or would you rather,
as I imagine it, see the old buffers being munmap()'ed before
requesting/mmap()ing the new buffers?)?

Thanks for any comments,

Ronald
