    Are you certain a full hour recorded?

    when i view the transferred .tivo file (using VideoRedo) it is complete. corresponding .mpg file is short and size is considerably smaller.

    First report I've seen of tivodecode not completing. Is the exit status normal from kmttg - i.e. no errors reported? If it is not completing I would expect an abnormal exit status of some sort. Also try playback with VideoLAN VLC to eliminate possibility of faulty mpeg2 codecs (though if you say the file length of mpeg is significantly smaller that TiVo then that doesn't seem to be the case).

    Maybe you should open an issue on the Google code site?

    I've found the problem. I was using a FAT32 drive as the destination for the .mpg files.
    4GB file size limit caused them to truncate.
    Unfortunately there is no indication in the error log.

    Is there a way to have auto transfers only d/load from a particular Tivo?
    I record some shows on both a S2DT and a TivoHD, and would prefer to just grab the shows from the HD for processing...

    Thanks!

    Maybe someone else will have a better suggestion, but it seems like a very simple solution to me. Just configure kmttg to see one of the TiVos, and turn "Look for Tivos on network" off.

    Well, the only problem, is that there are other shows I need to get from the S2s (ones with the no-copy flag set in HD)...
    I just thought it would be nice to be able to auto transfer a certain show only from a certain Tivo...
    (Shrug)

    Oh well, I guess I'll need to work on my season passes/auto transfers instead...

    Thanks,

    I didn't get that from your first question. I once needed to do this too. (I've had the feature request in to Kevin for a while, to be able to direct a season pass auto transfer to a particular TiVo, but I don't need this anymore)

    What I did to solve this particular problem (at the time) is simply install two instances of kmttg, each of them configured to see a single TiVo.

    Hi,

    Does anyone else have temp MP4 files hanging around (not being deleted) after the encoding step?

    I use Ffmpeg for converting the MPG shows to MP4 and then pushing them back to the TiVo HD with pyTivo, and I've started to notice that a lot of the shows (not 100% but about 80 or 90%) have an additional MP4 file with the same name but with an extra "temp" and a random number in the name.

    It's not a big deal to go through and delete them, but I never used to get them before and I'm wondering how this started.

    Thanks,

    Cam

    Finally got around to giving kmttg a try ... very nice. I was going to run it on Linux where I run pyTivo, streambaby, etc. but don't want to have to install wine just to get comskip functionality. Plus, I own VideoRedo so I installed it on my Win7 PC to try out the end-to-end features.

    It seems to work great, except that my resulting MP4 files (both times I've tested) have no audio. The .TiVo, .MPG, and cut.MPG all play fine with audio, just the MP4 is missing it. I've tried the h264_high and tivo_hd profiles using the ffmpeg that kmttg downloaded.

    Also, the with the first file I tested with, the MP4 file ended up being double the size of the original MPEG-2! :confused:

    IS the audio in your mp4 file supposed to be AC-3? AAC? Is your ffmpeg compiled with support for that?

    As for the resulting file size, that's entirely up to the bitrate you choose. mp4 is not supposed to be 'smaller' than mpeg-2. It's just a different encoder. If you select a higher bitrate, then you will end up with a bigger file.

    I'm using the ffmpeg that kmttg downloaded for me, which looks like it has the AAC decoder disabled:

    Code:

    Maybe I'll try using the ffmpeg that comes with WinFF instead (or I'll just try it on Linux again using my custom-build ffmpeg and just skip the commercial skip part for testing purposes).

    Is there a reason you still need the "Create sub-folder for each download" option? That option can be quite confusing for those who want a separate folder for each series.

    If users want to create a sub-folder for each download, they can just as easily do that using a [\] in the file naming scheme.

    Is there supposed to be directory cleanup? If you (a) set each series set to save in its own subfolder folder, (b) enabled the option to remove .TiVo after file decrypt, and (c) set different drives/folders for the .Tivo output and .Mpg output, then TiVo output series subfolders not deleted along with the file. You're left with empty series folders.

    On a related topic, here a way to have all file processing done an internal drive with final output stored on an external drive? I don't see any obvious way to do this.

    Decryption, VideoRedo Quickstream Fix, and comskip / adcut are all disk intensive. Those are operations you'd want done on your internal hard drive, rather than an external drive. But when you choose a MPG output folder, that applies to both the decrypted MPG and the saved output from VideoRedo. I don't see any obvious way to setup VideoRedo so Quickstream Fix is always performed on the internal drive and the final MPGs are saved to an external drive.

    I have an old Womble MPEG-VCR (v3.14). Is this the same you have or different?

    I'm thinking there might be some file size limitation for this app as it crashes when I try to open a decrypted HD TiVo recording (4.81GB).

    Many players can't handle AC3 audio in mpeg4 container. If you use VideoLAN VLC it does support that.

    Those high rate encodings are overkill if you are looking for space savings. Try ff_ps3 profile instead for good quality lower size recording.
    NOTE: The ffmpeg installed as part of kmttg DOES support AAC audio, and the ff_ps3 profile uses it as do some other profiles.
