You should be able to pull h.264 files to any TiVo, it's just that they will be transcoded.

Using an arbitrary seriesId used to work but it that got broken at some point though may bne working again with the latest fix. I haven't completely tested it again.

What does seem to work this point (at least for me) is using a seriesId of the form SH9nnnnnnn where nnnnnnn is 0001101 or greater. I put movies I want to group into the same folder on the PC and create a default.txt file with the relevant information. You must also change the title entry in the individual metadata files to episodeTitle and remove or comment out the movieYear and isEpisodic entries.

Example of a default.txt:
Code:
seriesTitle : The Lord of the Rings
title : The Lord of the Rings
seriesId : SH90001112
isEpisode : true
isEpisodic : true
example of a modified metadata file:
Code:
episodeTitle : The Fellowship of the Ring
#movieYear : 2001
description : From the idyllic shire of the Hobbits to the smoking chasms of Mordor, director Peter Jackson follows Frodo Baggins (Elijah Wood) as he embarks on his epic quest. The movie -- which nabbed 13 Oscar nods -- boasts an outstanding cast, including Ian McKellen and Viggo Mortensen. This extended version includes unseen footage.

You'll note that I also commented out the mpaaRating entry. While the movies still group, its presence seems to cause a problem with the most of the metadata.

You'll also note that I added originalAirDate and time entries. If you choose to do so, DO NOT USE A time ENTRY PRIOR TO 1970! YOUR TiVo WILL CRASH!

I'm not sure what DTVCC Transport mux & 608 captions are, but does this mean that it's possible to create a H.264 file with closed captions that can be enabled or disabled at the tivo?

I tried to create Tivo compatible captions with H.264 encoding file, but haven't gotten it to work on my Premiere. When I try to turn the captions on at the tivo side, the tivo says that the program has closed captions but does not display any captions. Can someone identify what I'm doing wrong.
1) Transfer video (as program stream) from Tivo to PC using kmttg
1a) decrypt with tivodecode under kmttg
1b) run videoredo QS Fix under kmttg
1c) run videoredo ad detect under kmttg. Manually review ad cuts in videoredo
1d) run videoredo ad cut under kmttg
1e) run ccextractor under kmttg
1f) encode with modified videoredo h264-MP4 profile (resolution changed to 720x400 to decrease file size)
2) Run mp4box to mux in .srt captions from ccextractor into the mp4 container with video and audio. Mediainfo attached
3) Push video to Tivo (Doesn't look like it's transcoding):

I went to the Videoredo forums and downloaded with latest beta (build 646). Encoding with this newer version of VideoRedo allowed me encode H264 and have the closed captions work on my Premiere. No need to mux in the .srt like you said. Thanks moyekj and the Videoredo folks.

Part of it is that a push has to be initiated through the mind.tivo.com server. Note that that is just the initiation. The actual data still goes directly from your computer to the TiVo.

1. As mentioned, push requests go through the mind server. This doesn't involve pyTivo working, though; it's just waiting.

2. If you're pushing something that needs to be remuxed to MP4, that's done before the request is sent, because it takes two passes to make a pushable MP4. (Program streams and transport streams can be built in a single pass, so they're done concurrently with the transfer.) If you actually see CPU and disk activity, this is probably the reason.

3. Once they do start, push transfers aren't immediately playable the way pulls are. This is because the push mechanism was designed originally for transfers of podcasts (TiVoCasts) over the Internet, which TiVo assumed could be slow, and I believe they didn't want the user experience to involve a lot of starts and stops (the stereotypical "buffering" situation).

I'm archiving several series and some movies from the 60's. Why will these dates make the TiVo crash and is there a decent workaround for it?

Unless you enter it by hand or are using a modified metadata generator (as I am), you don't need to worry about it. It's not the originalAirDate that is the problem. It is the date/time of the actual recording. That is what the "time :" entry in the metadata controls. If you don't have an entry for it in the metadata, it will default to the actual date/time of the transfer to the TiVo.

I suspect that what is happening is that the TiVo is using some fixed date to calculate a value for sorting purposes and that a negative result generates an arithmetic error in the CPU and, as is typical with TiVo s/w, there is no error handling

 01-06-2013, 02:00 AM #3979 tjtv Registered User   Join Date: Jul 2007 Posts: 31 I recently installed the new version of pytivo that allows pulling h264 files directly. It really works great, many thanks for all your hard work. Pulling is much more user friendly than the old push method that was required. I am running pytivo on a pogoplug. The pogoplug has a very underpowered ARM CPU, which is no problem for most of my videos since nothing needs to be transcoded. However, some of my files have h264 video/dts audio. The dts audio needs to be transcoded to AC3, and the pogoplug CPU is not powerful enough to do this in real-time. Does anyone know of a way to speed up the dts -> ac3 conversion process? If I could find a way to make the pogoplug do that conversion in realtime I think I have finally found the holy grail.

I am in a similar situation. I have just been using a homemade script to convert the DTS audio when the file is first placed on the storage device so it is ready to use when I want to watch it. I'm working on cleaning it up so I can release it, maybe it will help. I'd like to get the script to where it would scan a folder and convert all files that meet the desired criteria.

As to speeding up your current process, there is not much you can do. You may be able to increase performance very slightly by compiling an optimized FFmpeg binary and using the fixed-point decoder/encoder but it's not worth the time in my opinion.

It seems that there is a new FFmpeg release (1.1) yesterday so I'll test that instead and upload it soon.

Ok had to reinstall windows and seem to have everything running correctly until I try to push menu. The commend prompt indicates there is a share problem...but I've got the path of the folder done correctly. I've attached the command prompt and the http://localhost:9032/ images. Any ideas what's going on?

There is not a pyTivo movie plugin. Likely you got the share name and the plugin type mixed up.

A generic video share will be described like this in the configuration

[Share Name]
type = video
path = C:\path\to\share
etc....

So yours may look like:

[Movies]
type = video
path = C:\Videos

Post your pyTivo.conf file after removing any sensitive entries, like your password and/or MAK. Your screen shot of the browser display indicates there are no TiVos nor shares defined.

I'd rather not have to run a conversion script as it's just one more thing that can go wrong. I was wondering if there was a way to set a lower quality audio option in ffmpeg that would make the conversion quicker, but I guess that's not possible.

The pogoplug that I have is a B02 model, it has a dual core 700mhz cpu. There is another revision of the pogoplug called E02 which has a single core 1.2ghz cpu. I know that it's not necessarily a scientific measurement but the bogomips rating of the B02 is 2x279, whereas the E02 has a 1150 bogomips rating. I'm wondering if the extra processing power of the E02 will be able to keep up with realtime DTS -> AC3 transcoding. I'm reluctant to spend the $35 on the E02 model without knowing for sure. 01-07-2013, 11:06 AM #3987 Raver Registered User Join Date: Feb 2009 Posts: 57 Quote:  Originally Posted by lpwcomp Post your pyTivo.conf file after removing any sensitive entries, like your password and/or MAK.

The pogoplug that I have is a B02 model, it has a dual core 700mhz cpu. There is another revision of the pogoplug called E02 which has a single core 1.2ghz cpu. I know that it's not necessarily a scientific measurement but the bogomips rating of the B02 is 2x279, whereas the E02 has a 1150 bogomips rating. I'm wondering if the extra processing power of the E02 will be able to keep up with realtime DTS -> AC3 transcoding. I'm reluctant to spend the$35 on the E02 model without knowing for sure.
You can use a lower quality audio setting for pyTivo to transcode with but it will not drastically increase your framerate. DTS is a processor intensive codec to decode...and then you add the reencoding to AC3 on top of that.
