I've considered this a little more this morning. My limited experience of this topic had gotten me confused.
It seems to me that the kind of deinterlace I require is trivial in all pixel formats where there is no chroma subsampling in the height axis. I'd become confused and was thinking that YUV422p was a format like that, but it isn't. However, YUV420p does have vertical chroma subsampling, and thus, unless i'm still horribly confused, would be considerably more complex to deinterlace, because the output chroma channels will need to be computed from 2 different input channels. I'm not sure how to do that (is it as simple as Uoutput = (Ua + Ub) / 2 ??). _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
