  1. Re:Just dumped MythTV on Preview the New MythTV User Interface · · Score: 1

    the thread started off talking about using another player instead of their own internal player, so how specifically thier own player fails for live tv I'm not sure

    The thread started off with this.

    Their issue was that mythtv didn't really handle external video well. I agreed and wished that external video was handled seamlessly as if it were just a regular TV show (ie it showed up in the regular program list and didn't need a separate plugin with a separate interface).

    Are you trying to transcode it inside of or outside of myth?

    Outside.

    If you are talking about limited transcoding ability of myth's built in transcoders, I'll definitely agree with you there.

    Yup - that would be why I'm using an external transcoder.

    The nice thing, however, is that you can let any program do the transcoding.

    Yup - as long as you don't mind the video not actually playing back correctly, which brings me back to my complaint. :)

    If you can supply a working command line that will transcode MPEG-2 with an AC3 audio stream down to 720x480 or thereabouts while keeping the 5.1 AC3 audio track intact such that it can play back as a regular TV program and work with commercial detection, I'm all ears. I can transcode the files and play them with mplayer just fine (including with mythvideo calling mplayer). I just can't play them in the program guide, which means I can't use commercial flagging and I lose all those wonderful features myth has for organizing my shows and displaying metadata from the program guide.

    Trust me - I didn't start using mythtv last week. The whole reason I want to downsample the HD (besides saving space) is that my EPIA M10000-based diskless frontend can't playback hi-def video, but it handles the 5.1 AC3 audio just fine via SPDIF. I could care less about the high-def output (and I'd already be more at DVD-quality than off-the-air quality even with the downsampling), but I do appreciate true 5.1 sound.

    Again, I'm not exactly volunteering to rewrite all of mythtv and I've contributed all of one patch to the mythtv source, so I don't expect all the devs to cater to my every wish. However, that doesn't mean that I can't see the room for improvement either. If the devs don't have the same itch as I do, fine - they can work on what suits them - I'm getting far more than I paid for, right? :)

    I'm talking about better codec support for live TV. :)

    Don't get me wrong - I think MythTV is wonderful, which is why I use it. But there are areas where it could use improvement. I won't be overly critical, since I'm not exactly volunteering to rewrite the whole thing.

    I agree that a seektable probably wouldn't hurt with stuff like cutlists. So, implement the seektable for foreign media - you import a foreign media file into myth and it builds a seektable. That isn't a reason not to support foreign media - just one more thing to implement when you do support it.

    As far as HD video formats - couldn't agree more with what you said, but I'm not sure how it is relevant. My HD card records the ATSC MPEG-2 stream off the air - often with AC3 5.1 audio. I'd like to turn that into an mpeg-2 or mpeg-4 lower-resolution video stream with the AC3 5.1 audio remaining intact. That is very hit-and-miss in my experience. Myth is very fussy with the video format (particular with keybrame spacing). It also doesn't help that most of the transcoding tools don't handle the AC3 well either - you can run into problems with re-interleaving the audio into the container.

    Again, mythtv is wonderful. However, just a few tweaks would make it better. If nothing else the smaller change of indexing frame numbers rather than keyframe numbers in the seektable would probably help (the devs have discussed this very change - the change is very simple but the pain would be for those upgrading their databases as you'd need to update all the frame numbers). I completely sympathize that these changes aren't easy to make.

  4. Re:Just dumped MythTV on Preview the New MythTV User Interface · · Score: 1

    Ok, the post I replied to pointed out that mythtv didn't handle TV shows obtained from sources other than off-the-air well. I agreed.

    Sure, you can play them via mythvideo - but this is a kludgy interface. Fast-forward/rewind don't work well. Cutlists and commercial skip don't work at all. The shows aren't organized in the main program list, there is no autoexpire, etc. Basically mythvideo is just a browser and then it can spawn an external player (or use its more limited internal player).

    What I'd like is for a media file off the internet to look just like a show I recorded an hour ago. If I have a media file with commercials in it, I'd like to be able to flag them. I'd like to do that even if myth didn't record that media file.

    Try sticking a random avi in your mythtv video directory. There are tools to try to put it into the regular program list, but the file probably won't seek correctly. I can't tell you how much trouble I've had just trying to transcode myth-recorded shows without using mythtranscode (in my case I want to transcode hi-def to standard-def while preserving the AC3 audio stream).

    How do you use an external player for watching TV (with commerical skip, etc)? Everybody here is talking about mythvideo - I was talking about the main interface used for TV.

    I'd lke to be able to watch a TV show as if it were recorded by myth, even thought it wasn't recorded by myth. I don't want some plugin that doesn't support 90% of the mythtv feature set. Sure, I use mythtvideo because I have to - not because I want to... :)

    No it isn't.

    MythVideo - which is a mythtv plugin - is a frontend to mplayer for external files.

    You can't integrate external video files into mythtv proper (the interface where you can easily fast-forward, rewind (not skip), and do editing/cutlists/commercial-flagging/etc). That is the component that could be improved by allowing the use of external video.

  7. Re:Just dumped MythTV on Preview the New MythTV User Interface · · Score: 1

    I was talking about using an external player WITHOUT using mythvideo.

    The whole point is that external video files aren't handled well by mythtv. At best you can use mythvideo which is very stripped down compared to the interface used to play recorded TV shows. For example, you can't set up a cutlist or remove commercials using mythvideo.

    We can't even explain why physical constants are what they are - so how could we know if it is even possible for them to be different? Sure, there is always complete fantasy - but that isn't science.

    Science isn't any proposed explanation that doesn't use terms often associated with theology. Science is proposing a hypothesis and then testing it. If you can't even propose a way to test a hypothesis then it isn't science. Test proposals that are fantastic in nature also don't count.

    Agreed - it would be nice if foreign media could be seamlessly integrated into the MythTV interface. Mythvideo is very primitive by comparison (the interface used for random avi/ogg/mpg files/etc).

    One issue is that mythtv implemented their own media player, which means that only a few codecs are supported and there are very strict limitations on the video stream. For example, if keyframes aren't spaced completely uniformly the seektable breaks and any attempt to seek causes all kinds of problems. I think a better approach would be to use some other media player as the actual playback method and have myth focus on the value-adds like indexing the content, maintaining cutlists, GUI, etc. Mythtv would basically be a front-end to something like xine/mplayer. Why re-invent the wheel?

    "..but it is not in the interests of the US to fall behind either" Fall behind who? We currently have the most powerful military in the world. There is no threat to us, so we make one up, and then use the Air Force to kill Pakistani wedding guests. No one is a threat to us on our own soil, so we are planting missiles next to Russia to try and start up the Cold War again.

    Again, I'm not a fan of getting entangled in foreign wars unless seriously provoked. That doesn't mean that the army can only use following an actual military attack against US interests, but it also doesn't mean that we should be continuously engaged in some battle somewhere. As far as missile defense goes - it isn't a bad concept. Putin is just saber-rattling - a few ABM sites in Eastern Europe isn't really going to do anything to stop a full-scale Russian nuclear attack - but hey, if it makes for popular TV back home why not rally the voters?
