MythTV 0.25 Released, New HW Acceleration and Audio Standards Support

unts writes "The highly configurable Linux PVR, MythTV, has reached the 0.25 release, over 500 days after the previous full release. New features include VAAPI support, E-AC3, TrueHD, and DTS-HD audio, the ability to control other home entertainment devices via HDMI CEC and additions to the API to allow HTTP live streaming. The release notes for 0.25 don't reflect the release status at the time of writing, but should contain most of the relevant changes. MythTV can be used as a backend (recorder) and frontend (viewer), but can also feed other frontends such as appropriate versions of XBMC. Hopefully the new HTTP streaming API will lead to even more ways to get your video fix."

      I actually LOVED MythTV...back when I was watching HD over the air, in combination with getting free analog cable tv from my cable internet connection....there were also some HD (local stuff) on that unfiltered cable feed.

      However, I've moved about in recent years, and at the current new place, can't find the filter to remove for that cable internet connection. And now set up with UVerse, I wanted lots of HD content for new big plasma tv.

      I wish there was a way to integrate MythTV with Uverse....but until I can find a way to do that, Myth is not something I mess with any longer.

      I did prefer it...great for setting recording filters and keywords, etc. Much better than any DVR that comes with cable or uverse or satellite.

      In a nutshell.

      The larger picture is, the programmers often ACTIVELY reject offers of critical help on interface design and usability, not to mention requests to streamline the installation of basic hardware such as remote controls. For instance, the Mythbuntu page for using ATi Remote Wonder remotes, which were immensely popular and are still readily available in retail packaged alone or with ATi's capture boards including the All-In-Wonder HD line. Setup for these things is a nightmare - command line garbage, edit this or that file, go see "this other page" to find out how to get all the buttons working.

      Would it REALLY be hard to set up a script that could enable the necessary settings? Of course not, they've done it for a number of the other remotes by outfites like Hauppauge. But because scripting that isn't "sexy" and some of the programmers are still acting all butthurt about ATi not having open drivers before AMD bought them out, none of the MythTV or Mythbuntu team want to get off their ass and integrate such a script into the main trunk even if someone from the outside submitted it.

      It's shit like this that hinders F/OSS adoption by the larger population.

      I'm in the same boat, having Comcast with a number of HD channels that I like to record and watch. For some lucky few, such channels are available via firewire, unencrypted out of the cable box. I am not so lucky.

      To remedy this, I have a Hauppuage HD-PVR. It is basically a $150 component + digital audio to h264 hardware encoder. Myth uses it combined with firewire channel changing (ir blasting works just fine though) to record all of my premium channels. The decrease in quality is barely perceptible even on our large set, and it is a small price to pay for such a great system.

      I don't think it's ever going to penetrate the commercial space now ; digital TV has made it much easier to make products with PVR features and you can get devices that are basically an HDMI dongle with an SD card slot that perform the significant function (stream recording and playback), you have the likes of Ubuntu TV and the built in OS that most digital TVs seem to have these days.

      I cut my teeth on Linux with MythTV though - at the time, I had to use Gentoo to get the bleeding edge kernel support for my DVB hardware. I learned a lot. I'd guess it's still a reasonable way to learn something about Linux, even if it's much easier than it used to be. Which is another way of saying it's a hobbyists project.

    Legit question, for several reasons, and I'm a huge MythTV fan, have been for 8+ years, but I still use it. Here's why, and why not:

    1.I no longer frequently use the video and music plugins, since so much content is streaming over the Internet or other devices. I have some old DVD/BluRay rips still on it that I sometimes watch.
    2. I no longer use it to watch any DVD's, for the same reason above, AND the DVD player in it sucks at playing 50% of the DVDs I have, and it doesn't play BluRays.

  6. mythnettv by vlm · · Score: 2

    I wish they would integrate mythnettv into the mainline. Its an addon that shoves video podcasts into your "recorded tv shows" list as if they came over the air (or cable or satellite or whatever). Most of what I watch on "TV" is from revision3 or twit.tv or ted talks rss feed now rather than the old fashioned "tv" networks and it all comes from mythnettv run by a cron job every night pulling a bunch of RSS feeds.

    Another thing thats bugged me for years with my myth setup at home is they've got all this psuedo-intelligent magic AI post-processing after recording that makes commercials disappear... literally hands free you're watching TV, a break comes up, it skips the commercials. Very nice, very impressive, something no other DVR has, a killer feature that makes it impossible to even consider trying another. However, for years and years they still can't figure out a way to auto-zoom widescreen content on a narrow channel shown on a wide display (in other words, a tiny pic in the center of a giant black border). You'd think tech smart enough to detect and autoskip commercials could figure out when a TV show gets "framed" and adjust the zoom appropriately. Maybe this is something they added back in 0.23 and I just haven't noticed yet, donno.

    Another thing that bugs me is digital dropouts make a star trek like sound in addition to ugly picture and I wish the backend could be convinced if the mpeg stream turns to crap that it should cleanly eat the bad checksum frames and mute the sound stream. Doesn't happen often. But the concept of a squelch function when the input drops doesn't seem like rocket science to implement. Even a cheap TV can bluescreen on lack of input signal, why not my myth backend?

    If you sign up for schedule data from schedules direct, how come myth can't tell you when it expires other than your listings disappearing?

    Back around 0.20 there was a really nice streaming audio player and I found it amusing to listen to various world wide stations on my TV. That disappeared in recent versions, a rare feature regression. I miss that.

    Honestly 0.24 is/was about 99% perfect, its just these weird corner cases that still bug me after years and years, and it sounds like 0.25 has fixed none of my real issues while adding support for stuff I simply don't care about.

    I am pleased that its 1998 in mythtv land so they finally support ipv6...

    I've been using MythTV for a couple of years on Mac Mini (running OSX rather than Linux), talking to an HDHomeRun network tuner connected to a broadcast antenna in my attic. The team has really improved the OSX port in the last few years, with the only lack of Linux parity being in the realm of hardware-accelerated playback.

    After dealing with the confusing setup screens and active channel scans, it has worked brilliantly, especially since the 0.24 release. The scheduling software is really good, especially using the web frontend. Watching TV on any computer in the house has been very convenient, and the automatic commercial skipping is pleasant.

    Between broadcast and online sources, I get most of what I want to watch, the exceptions being Game of Thrones and some cable-only basketball and hockey broadcasts.

    Projected support costs of Linux version vs. Projected revenue from it would be my guess. It's oft-repeated unfortunately.

    Yes, it is a frequently cited reason, but not necessary the true one. Netflix used to work on Linux (until they switched to Silverlight). The last explanation from a Netflix executives of why they still have not restored Linux support was a long string of technical gibberish which basically boiled down to "because it isn't Windows". It was clear that he had no idea what it would take to get Linux support back.

    It is not just Netflix that does this. Estimates of how hard it would be to support Linux often assume a separate from-scratch development effort would be required. Often all that is really needed is to provide what they already have in a slightly different form. Sometimes this just means a new installer. In other cases all that is required is a few web pages. Very often the effort would benefit all of their uses. For example, if Garmin were to provided direct links to firmware files and instructions for copying them to the right place on the GPS, it would save users a lot of trouble when the just-click-this-and-don't-worry-your-pretty-little-head-about-it programs fail.
