seems to work fine here, thanks! btw, a few things I noticed regarding softdevice but I didn't bother to mention (until now), but maybe that input is appreciated: - depending on the pixel format, the entire picture and overlay shifts slightly left and right, where: - YV12 is one pixel right compared to YUY2 - YV12 and I420 are perfectly aligned - the pseudo alpha blending never worked for me neither with different nvidia cards nor with matrox cards - I would expect the overlay to be pixel aligned (as it is on the full featured card) i.e. without strange scaling/alignment effects while in fact it changes slightly with each channel (duplicating pixels and sometimes even antialiasing pixels) see http://www.13thfloor.at/~herbert/chan{05,14,26}.png that aside, I'm happy that softdevice was not abandoned and seems to be well maintained now thanks for your work and time, Herbert > -- > Stefan Lucke > _______________________________________________ > Softdevice-devel mailing list > [email protected] > https://lists.berlios.de/mailman/listinfo/softdevice-devel _______________________________________________ Softdevice-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/softdevice-devel
