DXVA compatible video

[Ma-Xell]

Hi! I encoded 3 videos using x264 all with the same settings.
The first 2 were of resolution 768×432.
The last one was 1024×576.

The first two played on my nvidia ion netbook using DXVA
however the last one did not. My question is: is the resolution
the reason why the last one did not play? I know that some
settings might not be supported at higher resolutions but I
thought that was only at HD and above.

Anyway the settings that I used were: cabac=1 / ref=5 / deblock=1:0:0 / analyse=0x3:0x113 / me=umh / subme=8 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=2 / 8x8dct=1 / cqm=0 / deadzone=21,11 / fast_pskip=0 / chroma_qp_offset=-2 / threads=6 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / constrained_intra=0 / bframes=3 / b_pyramid=2 / b_adapt=2 / b_bias=0 / direct=3 / weightb=1 / weightp=2 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=crf / mbtree=1 / crf=23.7 / qcomp=0.60 / qpmin=10 / qpmax=51 / qpstep=4 / ip_ratio=1.40 / aq=1:1.10

If you need I can upload the video.

:thanks:

I think the resolution was probably to blame. If you'd upscaled to a standard resolution like 1280x720, or kept it at 720x576, it would have been fine

Hardware decoding tends to be resolution specific, in my experience. I'm not sure why...

Yes, I wanted to avoid resizing other than correcting the aspect ratio.
The video was really sharp and good quality at that resolution so didn't want to ruin the quality by down, or upscaling.
Maybe what I could do is encode at 720×576 and flag it as 16/9...
