crop borders on s-video input on HVR-1600?

[sgilani]

my IPTV provider annoyingly places 40-pixel wide black borders on the left and right of the picture, and there's no setting or any way of changing that output from the box.

i'm using the s-video input on my HVR-1600. Is there any way that I can somehow crop the borders? I'm stumped on this one.. anyone have ideas? :confused:

I also have a HVR-850 and HVR-950Q sitting around (with a/v cables); can that SoftMCE stuff do it by chance?

sure lots could be done on postprocessing / recorded shows, but that doesn't help when watching live TV (or timeshifted TV)

Would a custom aspect ratio work for you? Editing the </AspectRatioModes> in config.xml?

i know of some crop filters you could insert, but not sure if that's possible without any control over cap graphs...

other than trying to mod the driver .inf, a custom aspect ratio is probably best way to go..
or if your cap source has a resolution of 704xXXX use that..may work..

hmm,so you get a really skinny screen?
[analog is always 4:3 + black bars on sides = really skinny..]
almost sounds like your stb is setup wrong..[16/9 or 4/3]
sometimes it's a 'hidden' feature..like a remote hotkey and nothing else..check manuals or on the web...
boxes often have hidden features and reset key combos we never know about..

I thought of using negative values in there and use VMR9, but then I'd have to constantly change aspect ratios when switching between local channels and the IPTV channels.

yeah, it's a very skinny screen. unfortunately there isn't any setting on the box, and the provider gave me an excuse saying that their system streams channels at 640x480 and then the box adds 40 pixels to the left and right to make it 720x480, and that there is nothing I can do to crop those borders or stretch the picture rather than add those pillars.

hmm I could use crop filters along with the GraphRecorder plugin, right? that might be the solution... what do you suggest?

ffdshow can crop on the fly. You could set it so that the input at the designated resolution would be cropped. That way you could watch live tv or recorded shows at the proper aspect.

true, but then it would crop every 720x480 video, which would needlessly be butchering up some of my local channels which are also 720x480. ffdshow as an MPEG2 decoder in GBPVR doesn't play nice with the mux filters needed with ATSC sources either, but that's another issue.

just to test, I tried out GraphRecorder with a capture graph that included the ffdshow raw filter set to crop the borders, but I end up with very bad a/v sync issues in the output.

am I just out of luck? i'd hate to have to stop using GBPVR over something like this.

I'm not aware of any way hardware encoder devices can be made to crop part of the picture prior to them encoding the raw video signal.

You'd probably need to come up some (long and CPU intensive) post-processing reencoding script.

.. the master has spoken.

you're right, it seems that way.. pBS, which crop filters were you referring to; if it plays nicely with the Hauppauge capture filters and the GB-PVR Writer then it might just do the trick as a GraphRecorder solution.
