Is there a way to adjust the video myth is recording? I am getting black bars on the sides. The picture also seems off center to the right. It is quite noticable when I play the files on a Windows machine. I checked the mythtv-setup and I didn't see in there.

Any assistance would be greatly appreciated

thanks

What does this have to do with KnoppMyth?

Because KnoppMyth/MythTV is recording the video. I guess I should have posted in the MythTV section.

Please excuse my mistake

My point is, if the issue is with playback on Windows. What does this have to do with Linux. As far as I'm concerned, Windows is Off Topic.

Well that's certainly a viewpoint, but a rather provincial one. He was clearly asking why MythTV is creating recordings that aren't an accurate representation of the incoming signal. Windows is simply a convenient point of reference to demonstrate that.

As I've posted in another thread that hasn't received any responses yet, KnoppMyth seems to be very antisocial in its file formats. I illustrated that by demonstrating that KnoppMyth CAN create DIVX files that play on Windows, but it apparently doesn't do so with the built in transcoding and when it does create them it apparently can't play them back.

Now, I asked for info on video file formats because I may be misunderstanding the issue, but my point is cross platform compatibility.

Linux has historically been the champion of cross platform compatibility and has more recently benefitted from businesses becoming more compatible. I see many fewer Windows/IE only websites and I think that's a good thing.

An attititude of "MythTV is compatible with MythTV, screw the rest of the world" is regressing 20 or 30 years into the "bad old days" of computer history.

Fundamentally MythTV is just a fancy way of recording and playing back video files. There is absolutely no good reason why those video files should not be in industry standard formats that are freely exchangable with Windows, MacOS, Solaris, BeOS, or any other platform that supports a reasonable set of industry standard formats.

If the issue that willie44 asked about is really a playback on Windows issue then it isn't really on topic, but if it is a symptom (as he suspects) of MythTV recording a distorted version of the incoming video signal in such a way that only MythTV can play it back correctly then it certainly is a MythTV issue.

well anything recorded from a pvr or hdtv card is industry standard mpeg2 with a different extention on it. as for the mpeg-4 and rtjpeg that mythtv uses you would have to ask Issac from mythtv as he is the one who wrote that, and I think you will find him MUCH less receptive to that kind of criticism than anyone here.

Now as to something else you said mythtv cannot create divx in and of itself (of course it could be coded to do so but is not currently) you have to use nuvexport (yes this is a separate program) to do this. this is a mythtv issue and should be addressed on the mythtv mailing list (good luck). The reason is won't play back when you do make it divx is a knoppmyth issue and comes from cesman being paranoid about getting sued.( a reasonable fear) so many, many codecs that can work with mplayer are not included. If you don't share his concern then you can fairly easily upgrade mplayer to play divx and every other codec on the planet.

I've been using Linux off and on for nearly 10 years, so I'm well aware that there are open source developers who consider *everything* to be criticism. "Works for me" is practically a battle cry among some. But there are also a lot of open source developers who do a phenomenal job of making things that work for everyone. The closed source world is filled with many responsive vendors and many unresponsive vendors, so it's not just open source either. Heck, I know a local bar/restaurant where the bartender gets annoyed when a group of 20 people walk in at 11:00PM on a Saturday night because he's trying to clean up and close the bar. I leave a generous tip when I'm there, but I always try to convince my group to drive twice the distance to a place where we get friendly service even if we come in after 1:00AM.

For my question, your comment about mplayer codecs looks like it's the hint I needed. I hadn't seen anything previously that indicated that the KnoppMyth version of mplayer is missing codecs. Knowing that I should be able to track down the missing files.

As for willie44's question though, I don't think it's an issue of file format but rather a tweaking of parameters. It sounds like he can play the files, but the video capture isn't properly synchronized to the video signal. I would suspect that he needs to tweak some settings that MythTV passes to his capture card similar to the video timings that are in the XF86Config file for video output.

Unless we suspect that Windows is adding black bars that aren't actually encoded in the file (which is possible, perhaps willie44 could post a few seconds of video somewhere so that others can look at it on other platforms) then it would be a MyhTV or KnoppMyth issue.

On the other hand, it could be a resolution issue. I believe the default capture resolution is 480x480. Since 640x480 is a 4:3 aspect ratio then his black bars could be as simple as viewing the 480x480 file in a 4:3 display. That doesn't explain his comment about it being off center though.

KnoppMyth R1 worked for me, so why improve upon it? I think I go above and beyond to make KnoppMyth better and better each day. I'm spurred on by the community (much thanks to rdt, Jesse, mk500, Xsecrets, tjc, nigel, Liv2Cod and everyone) that has built around it. I don't think my attitude is "works for me".

If willie44 needed greater clarification, then he should have stated as such. "I get black bars when I play back on Windows." As far as I'm concerned has NOTHING to do with Linux/MythTV or KnoppMyth. He didn't stated what format he was trying to play back or anything.

If I didn't care about cross-platform, I'd wouldn't include SAMBA, I wouldn't include CyberMediaGate (do you know how much time I spend getting just this to work?). I certainly wouldn't have included the "pretty" script. If you want cross platform capabilities for Windows, then you need to take that battle to the Pacific Northwest NOT here (PERIOD).

Since the inclusive of MPlayer (R1), I've stated that MPlayer is crippled. Simply put, I'm not going to put myself in the position of being a poster/whipping boy for the MPAA or any other organization (PERIOD).

Don't like the fact that I harp on folks, don't use KnoppMyth and don't visit the forum (PERIOD).

I am sorry for any problems my post caused. Since I am pretty new to Linux/Mythtv, I am sometimes unsure which section to post because. Also, communicating through writing is not one of my strong suits. I apologize for not being clearer.

After using Nuv2Disc to trancode a recording to xvid, It looked fine on my windows machine.

I still do need to figure out how to adjust my XFree86 settings (I think) to adjust how Live TV/Recordings are shown. I plan on searching to find a solution.
