1080p video in sage

[ncohafmuta]

I'm running the latest sage in vista 64 on a phenom 8650 2.3 X3 with 4G ram.

I see a lot of slowdown (unwatchable) when trying to watch 1080p videos in sage (usually mkvs). I use EVR, ffdshow and a codec pack.
720p works fine.
Same 1080p videos work fine in MPC Home Cinema.

Anybody seen this and/or have a solution?

Thanx,

What codec are you actually using for the video? Is hardware accelleration enabled? In general, codec packs are a bad idea, as they usually muttle up too much stuff, and you really don't usually need most the crap they include.

for MPC 1.3.1458 whatever the internal DXVA one is. sage, the one from ffdshow 3158, which i believe uses ffmpeg-nt
i believe i do have hardware accel. enabled in sage, yes. i have a geforce 8200 onboard.

looks like this was also mentioned in these threads (without an end all solution):

i'll have to try the readahead thing mentioned or maybe a different codec in ffdshow (maybe libavcodec or the ffdshow tryouts project) in sage when i get home.

What is in the MKV container. h.264 or MPEG2?
Whate video card?

If you are using ffdshow to decode your video, you are NOT getting hardware accelleration. FFdshow is software only. This is most likely your problem. If you've already got MPC, I'm pretty sure you can use the MPC codecs in sage, but I've never done so and you'd have to do a search here to find out if/how.

I figured this out. After turning debugging on, the log showed sage was using the decoder ffmpeg (which i assume is sage's internal decoder, because i dont have it installed anywhere).
No matter what i set h264_video_decoder_filter to, it still used ffmpeg. But when i set video_decoder_filter to something other than Default, such as arcsoft or cyberlink, then it worked fine.
So either the file isn't really h264 (which i don't think is true, based on what mpc and sagetv says) or sage is choosing the wrong type filter.
