TiVo has enabled some degree of H.264 support with the recent release of 9.4 and the YouTube HME app. It's about time. Now, the job is to get pyTivo plugged into this framework.
I've done a few minutes of legwork in this area with some help from wgw and wmcbrine, and while I haven't gotten it to work I've noticed some things.
I begun by adding the following lines to my pyTivo.conf file :
| Code: | format = mp4
video_codec = mpeg4 |
This allows me to browse a folder that contains H.264/VC-1 videos and select one for transfer. Once the transfer begins, I see a blue dotted item in my NPL. However, the recording is not playable. The duration remains as a 0:00 partial. Hitting "play" pops up the "please wait while more video is transferred" dialog box.
I also tried changing the MIME types from "video/x-tivo-mpeg" to "video/mp4" and "video/x-tivo-mp4", but that didn't work very well. Browsing a folder of H.264/VC-1 recordings showed the recordings as copy protected and/or incompatible, with the red circle w/ line through it. So, I had to back out these changes.
I'm using presumably clean H.264/VC-1 podcasts/trailers : a podcast from askaninja.com, and the 300 theatrical trailer in 720p.

That sounds promising.
Could you post a debug log from the original attempt where it looked like it was going to transfer?

I should also note that I'm using the ffmpeg build by rdian06 intended to help out on MKV playback. Those errors being spit out (Unsupported codec (id=86018) for input stream #0.1) are probably not a good thing...

Ah, my ffmpeg build doesn't include the AAC libraries so it can't handle the audio stream transcode from AAC to ac3. Which I think will result in the transcode failing completely.
Try switching back to the original ffmpeg_mp2.exe included with pyTivo and see if the transfer works. Keeping my fingers crossed for you.

No dice. At best, I'll get ffmpeg to try to start cranking through the recording, but just silently sit there. It looks like the TiVo isn't trying to pull the data across.
The original ffmpeg only includes support for H.264 decode, not encode. So, I've been trying various combinations of MPEG-4 formats and codecs with no luck.

Ooooooh! Wait a minute!
format = h264
video_codec = libx264
This actually starts processing frames, which is further than I've gotten before. It stops at frame 11, and complains :

Specifying :
bufsize = 4096k
Gets rid of the VBV buffer size error, but the transfer still halts at frame 11.

Hrmm. Another problem it seems is that the vob container format isn't designed to hold h264/mpeg4 video.
For testing, I think we can use the ffmpeg_params configure option to override the normal transcode command (based on the configure page) and just copy h264 video from your source to an mp4 container with no audio for now.
In pyTivo.conf, try setting:
| Code: |
ffmpeg_params = -vcodec copy -an -comment pyTivo.py -f mp4 -
|
I briefly tested this copying h264 out of an mkv to an mp4 file using my ffmpeg build and it seems to halve the framerate, but at least it should display video in a compliant mp4 container.

Try disabling transcoding completely and download an MPEG4/H.264 video from youtube and try serving that as-is (so it's a known-good playable MP4 video on tivo).
On youtube, pick a video and add fmt=18 to the querystring. This switches to streaming MPEG4/H.264 if that encode exists. You can download that video and serve it to tivo via pyTivo to see if pyTivo can actually stream H.264 content to tivo. If that works, then it's just a matter of getting the ffmpeg transcoding settings right for H.264.
e.g. for the skateboarding dog the H.264 player page is:
http://www.youtube.com/watch?v=CQzUsTFqtW0&fmt=18
To download the MP4 directly do:
wget -O skatedog.mp4 'http://www.youtube.com/get_video?video_id=CQzUsTFqtW0&t=OEgsToPDskKQL9DrX9SyylUtHsYW_6Ce&fmt=18'
I have attached a zip of the above video to save you the trouble. See if you can get tivo to play it using pyTivo.

Do you know of an easy way to disable transcoding in pyTivo? I thought the only way to do that was to mess with quite a bit of code. Overriding the ffmpeg command to copy the streams from one mp4 container to another is essentially the same thing without messing with code. I guess adding -acodec copy instead of -an to copy the audio stream to wouldn't hurt.

BTW, if you are using an mp4 source, you can do this to preserve the audio too. You're essentially copying the source mp4 to an identical mp4 without any transcoding:
| Code: |
ffmpeg_params = -vcodec copy -acodec copy -comment pyTivo.py -f mp4 -
|
The Tivo should now be able to handle stereo AAC because that's what YouTube uses.

OK, now we're getting somewhere. I downloaded the skatedog video you provided and slapped it into my share.
Using my previous configuration it actually progressed further into the transcode/download before the ffmpeg process was killed.

False alarm.... Your revised parm list is transcoding to mpeg-2, I think...

Just rename the file to end with .tivo - skatedog.tivo. This will short circuit the tivo_compatable check in plugins/video/transcode.py
Copying streams is not necessarily the same since the file will be remuxed.
