[linux-dvb] (forw) [directfb-cvs] DirectFB

[Denis Oliver Kropp <dok@directfb.org>]

Hi,

this might interest you.
I didn't look at the v4l code of the DVB driver myself, yet.

Example: buffer.pitch = 1440, buffer.width = 200

Log message:
Work around a bug in the DVB kernel driver (more likely) or the DVB hardware.
When using buffers with a pitch much higher than the width suggests (e.g. using
DSCAPS_STATIC_ALLOC and downsizing), the lower part of the video is cut off.

-          b.width = surface->width;
+          b.width = buffer->video.pitch / ((bpp + 7) / 8);
