MythTV 0.21 Released

kdawson posted more than 6 years ago | from the i-want-my-i-want-my-i-want-my dept.

Media 68

kormoc writes "The new release has lots of new stuff, notably: autodiscovery (less manual configuration of new front-ends), storage groups (no need for LVM/etc), support for multiple recordings on one DVB/ATSC multiplex, a couple of new plugins, some new deinterlacing / video display options, and many, many other things. The release notes page in the wiki has the list of what's changed, but it's currently a couple thousand checkins out of date. Grab the release from the download section and please at least try to read the docs before asking questions. The binary packages should hopefully be updated to 0.21 soon."

TV Listings (1)

coop247 (974899) | more than 6 years ago | (#22689694)

I'm pretty sure that MythTV used to use Zap2It to get their tv listing info, but a while ago we discussed [slashdot.org] that Zap2It was no longer going to provide this service for free. Where is this release pulling the listing data from?

Re:TV Listings (4, Informative)

shadow42 (996367) | more than 6 years ago | (#22689706)

The MythTV box I use at home (version 0.20) is pulling listings data from Schedules Direct [schedulesdirect.org] , the service created to replace Zap2it's listings service.

MythTV can get listing info from various sources, but I think most folks (at least in the USA and Canada) are now using Schedules Direct (http://www.schedulesdirect.org/ [schedulesdirect.org] ). Schedules Direct was set up by various folks involved with open source video/television related projects like MythTV in response to the Zap2It free listings shutdown and has reached its goal of getting enough subscribers to hit a price point of $20 per year for listings data (with a 7 day free trial). My experience with the transition was that it was pretty much seamless.

Re:TV Listings (2, Interesting)

CastrTroy (595695) | more than 6 years ago | (#22690076)

If you want continual quality listings, you're probably going to have to pay for it. I got SageTV, and with the $80? I spent, I get free listings, for well, I guess as long as they stick around. I've been using it for like 2 years now, so I guess based on that rate, it would be $40 worth of listings. I think people should be thankful that Zap2it lasted as long as it did. You can't expect some company to just feed you data that they've spent a lot of time gathering for free.

Re:TV Listings (1)

pembo13 (770295) | more than 6 years ago | (#22690964)

If you paid for it, are the listings really free?

Re:TV Listings (1)

BobPaul (710574) | more than 6 years ago | (#22696402)

Not technically, but what he paid for was the SageTV PVR software specifically. Since the listings are tied to SageTV (can't use them with MythTV AFAIK) it's not really something that would interest me, anyhow, but at least it's not an annual subscription like the alternatives.

Re:TV Listings (1)

Bert64 (520050) | more than 6 years ago | (#22691366)

But you can expect the TV companies to make the listings available for free, so all you really need to do is grab from all the different tv station's listing pages.
Some services also broadcast listing data with the program stream itself.

Re:TV Listings (1)

CastrTroy (595695) | more than 6 years ago | (#22691668)

Yes, but then you have to convince them all to deliver it in the same format, and then contact them when the mess up the format, or forget to deliver their feed. You've obviously never dealt with trying to get a data feed from some company who's main interest isn't sending out data.

Re:TV Listings (1)

Dr_Barnowl (709838) | more than 6 years ago | (#22693052)

In the UK, you can either get listings straight from the DVB-T signal, or free (for personal use) from an XML feed served by the Radio Times (a commercial arm of the BBC).

"In the UK, you can either get listings straight from the DVB-T signal, or free (for personal use) from an XML feed served by the Radio Times (a commercial arm of the BBC)."

That's way different, though. In the UK, you've already paid for that data from your TV's taxation. That's the same reason that non-UK IP addresses can't access new TV content on the BBC's website --non-UK citizens can't get free programming because we didn't pay our tax to the BBC.

Re:TV Listings (1)

I'm confused about something. . . (2, Insightful)

JSBiff (87824) | more than 6 years ago | (#22690218)

Ok, let me see if I understand this right. . .

People were upset that Zap2It wasn't giving free listings (and they'd rather not pay for the pay service), so they setup another *pay* service as an alternative? Why not just pay for Zap2It? Were they asking for an outrageous fee for the listings?

I mean, I could see it being reasonable to pay a small monthly fee for listings - I mean, it's gotta cost some money to assemble the listing data, and then the cost of running servers and Internet connections to publish those listings. Why create a non-free competitor to Zap2It, instead of just using Zap2It?

Re:I'm confused about something. . . (4, Informative)

digdogger (460799) | more than 6 years ago | (#22690258)

The problem with Zap2It labs was that there was no pay service (and they apparently weren't interested in providing one). Their main beef was the many commercial products that were using the service.

Re:I'm confused about something. . . (1, Informative)

Anonymous Coward | more than 6 years ago | (#22690300)

People *wanted* to pay Zap2It, but Zap2It wouldn't take their money. We don't know why (they do). So instead, SchedulesDirect did it.

Re:I'm confused about something. . . (4, Informative)

grommit (97148) | more than 6 years ago | (#22690424)

Because Zap2It wasn't offering a pay service for individuals anymore. Zap2It doesn't have the infrastructure in place to accept payments from thousands of individual people. They are built around accepting large payments from dozens of companies for those companies to use. Zap2It got tired of individuals taking advantage of their free service and they didn't want to bother with setting up a pay system for individuals so Schedules Direct was created to fill in the gap.

Re:I'm confused about something. . . (1)

guamisc (1174125) | more than 6 years ago | (#22690806)

That's incorrect from what I heard. Zap2It got tired of companies using their info without paying for it and thus had to shut down their free service.

Re:I'm confused about something. . . (1)

jack455 (748443) | more than 6 years ago | (#22725430)

I was on their mailinglist and they mostly complained about companies, but there were some references to people using multiple machines with the same key I think. It probably would've helped if users had voluntarily limited the number of updates they requested. I miss the service, but am thankful they were as accommodating as they were for so long. I still use zap2it.com for web based tv listings, but I don't scrape their site for the data.

The Faywood Assassin (542375) | more than 6 years ago | (#22703742)

Screen scraping, which is what this is, may be against the site's policy, and might be illegal.

Besides, this solution generally requires high maintenance as small formatting changes tend to de-rail the scripts.

I was not using MythTV in the pre-Zap2it screen scraping days, but I understand that it was a veritable nightmare of script maintenance

$20 per year is difficult after it being free for so long, but in my opinion, it is well worth it.

Bug Fixed in the SAA7134? (1)

Zombie Ryushu (803103) | more than 6 years ago | (#22689746)

I have a Myth TV machine using a SAA7134 (MSI TV Anywhere Plus) TV Tuner card, and although this card worked fine in TVTime, and mencoder/mplayer, I had horrible problems with automute in MythTV and I am wondering if this bug has been fixed. I can manually turn off the mute in the saa7134 Mixer, but really, it made me feel ripped off by the guy who sold it to me promising me "This model works in Linux" Well he was telling the truth.

I'd say it is best to go with the Haupauge (sp?) cards that are proven winners with MythTV...cheap and you can slap multiple ones in there to record/watch on different channels at the same time. That and they have hardware decoding/encoding which allows you to run slightly less powerful processors on the box itself....

The Wiki at linuxtv.org. V4l Wiki for Analog and DVB Wiki for digital tuners. Almost any tuner supported by V4L or V4L-DVB will work with Myth. In fact, *Myth* doesn't provide any support or lack of support for tuners, it relies of V4L for this.

dookiesan (600840) | more than 6 years ago | (#22691442)

It's a shame if Hauppauge cards are the best out there. I've been using them for the last 7 years or so. Picture quality has been horrible compared to my walmart generic TV. Although it's not relevant if you use Myth, the included software is pretty bad too, and I had to switch to MS media center handling all the recording (which does an awesome job, btw).

If you have media center on XP, I would highly recommend using it. The channel guide is downloaded for free. Handling of showtime conflicts, lack of space, and auto-recording as you watch are done very well. Fast forwarding is crap in that it's either way too fast or not fast enough, and there's no 30-sec skip ahead.

If anyone can recommend and point to a precompiled myth-for-windows binary, I would give it a shot.

DVB Multiplexing! (4, Informative)

batkiwi (137781) | more than 6 years ago | (#22689894)

Finally you can record overlapping shows on one tuner!
Example: You are paranoid of slight time changes, and record ALL shows with 5 minutes pre and post buffer. In the .20 and below this would use two tuners if you wanted 7:30-8pm and 8-8:30pm. Now it is smart enough to pull two streams off the multiplex.

It will also let you (if you're in australia) record ABC1 and ABC2 off the same tuner at the same time!

I tried using tv_grab_au and patching together scripts from several different places... I even had it working for about a year at one stage. In the end I upgraded the myth box to digital and in the process didn't bother setting up a tv guide and just left it on the 'grab from the air' option. Several days later it had and I now have seven day listings from each station. So yeah, just keep trying and it'll work some day.

Re:DVB Multiplexing! (0)

Anonymous Coward | more than 6 years ago | (#22691046)

If you're using digital TV, then they provide an EPG as part of the signal. If you already have an analogue tuner, I wouldn't upgrade unless you're certain that you'll get over ~30% reception - digital is a hit-or-miss thing, and if you can't lock on to the signal then you won't get it period (as opposed to analogue's snowy picture for low reception). Also, some channels have dodgy repeaters - I've gotten a lot of grief from channel 9's digital signal.

Re:DVB Multiplexing! (1)

squidinkcalligraphy (558677) | more than 6 years ago | (#22691302)

The EPG data from the digital signal is usually only for the next show or two AFAIK. If you want to set a recording then you probably need an internet based EPG system (shepherd works great for me)

k.a.f. (168896) | more than 6 years ago | (#22691750)

How does it decode two streams at once?

DVB transport streams contain four independent program streams each. You can in fact record four programs at the same time by simply writing the unaltered transport stream to disk. Decoding need not happen until you actually want to watch one of those programs.

Re:DVB Multiplexing! (1)

RiotingPacifist (1228016) | more than 6 years ago | (#22692602)

is the limit 4? i thought it was as many as you can cram into the bandwidth, in the UK we have 8 TV channels + other stuff on multiplex 2 (but i don't know if more than 4 broadcast simultaneously).

This was the 1 thing that kept me trying to figure out the less polished alternatives, but now mythTV can do multiplexing looks like ill be giving it a shot. I just hope theyve included advanced enough options when it comes to recording the multiplexes. Can you specify how long to keep an unused multiplex, so you can record channels without putting the effort to decode (e.g i could keep a 2 day buffer of dave on my HD but in reality im unlikely to save/watch the programs unless theres nothing else on)

Re:DVB Multiplexing! (1)

LordKronos (470910) | more than 6 years ago | (#22693022)

Mythtv doesn't record the raw stream. It duplicates the stream and then applies the necessary PID filters for each channel. The end result is that you get the same files you would have had you used 2 separate tuners.

makomk (752139) | more than 6 years ago | (#22691944)

It's not exactly well-described in the changelog (possibly because it's relatively old), but MythTV 0.21 has a nice feature for UK-based Freeview users who use the over-the-air guide data. It can use the episode ID now available in the guide data to identify if two showings are of the same episode, which is a lot more reliable than previously-available methods. (I assume this is the "BBC Series link functionality" the changelog refers to.)

Current Best MythTV distro? (1)

erroneus (253617) | more than 6 years ago | (#22692338)

I have to wonder how quickly the new Myth packages will be added to MythTV distros.

Lately I've been struggling with trying to find a working combination of things. I've tried MythTVOS-2008 and while it saw my hardware, didn't seem willing to put any readable display on the screen. Just loaded up LinuxMCE and I haven't been able to get past the initial configure screen thanks to my Westinghouse TV. (It seems to have serious issues with displaying certain resolutions)

I've got a Hauppauge WinTV 150 card, a "ATSC Digital HDTV Tuner PCI Card - Air2PC" thing an a generic type of system board.

I'm most comfortable with RedHat distros such as Fedora but MythDora is still based on Fedora 6 and that can't be good so I haven't even tried that.

There has GOT to be an easier way!

Last time I installed MythTV, I used Fedora Core 5 and followed Jarod Wilson's guide [wilsonet.com] and didn't have any trouble. The MythTV.org wiki also has an entry for installing on FC7 [mythtv.org] . I'll likely be upgrading to FC8 when I move to version 0.21, so hopefully there aren't any major changes from these directions. You'll need to wait for the packages to become available, but I don't think it will take long. BTW, I've got a Hauppauge 250 on a PIII 1GHz with 256MB and never had a problem performance-wise.

Two years with MythTV (2, Interesting)

Yeechang Lee (3429) | more than 6 years ago | (#22696814)

I've had a MythTV setup at home for more than two years now, and have posted [slashdot.org] several [slashdot.org] times [slashdot.org] about [slashdot.org] it. Here's my quick take on the major changes for 0.21 [mythtv.org] :

* Support for multiple recording directories.
* Support for recording multiple streams over DVB.
* New deinterlacers (and an OpenGL-based video renderer, but that's still disabled by default, as I understand it).

That's it. There are hundreds of other changes and fixes, great and small, but for most people these are the changes that'll mean the most. Despite the 18 months since 0.20's release (a way too-long interval, I'd argue [gossamer-threads.com] ), this is a testament to just how good 0.20 was feature- and stabilitywise.

Even bigger news than 0.21 is the forthcoming $299 Hauppauge HD-PVR [avsforum.com] , the first consumer-grade high-definition video encoder (and with promised Linux support, no less). Within a couple of months, anyone—not just those lucky enough to have unencrypted FireWire ports—will be able to record in real time full 720p or 1080i video and Dolby 5.1 audio from their high-definition cable boxes into h.264 format and play it back on their MythTV boxes. Be aware, however, that the h.264 recordings will for many likely require faster hardware [gossamer-threads.com] than what they're using for their MythTV frontends.
