WTV and/or DVR-MS files?

[brotherjohn]

Would it be possible to add streaming/transcoding functionality of wtv and/or dvr-ms files, please?
wtv is the file format for recorded files of the windows media center in Windows 7 and dvr-ms is the same for Windows Vista.

[zip]

provide "ffmpeg -i file" on those files to see if they can be recognized

[brotherjohn]

For the dvr-ms file, ffmpeg returns the following:

[zip]

The first one should be added to your library. What is the file's extension? It looks like mpeg2 video in asf container, so if your device cannot play it it should be possible to transcode it.
The second one seems to be a mp3 file - is that correct or is FFmpeg just playing games here?

[brotherjohn]

File extension of second one is wtv. This is a recorded file from TV (DVB-S) of the windows media center (Windows 7 32 Bit).
File extension of the first one is dvr-ms. This is converted from the first one with the built-in function of Windows 7: Right-click on the file and via context menu I've chosen 'Convert to dvr-ms'. I guess, it's the format of recorded TV-files of Windows Vista, too.

My client devie is a Sony TV Bravia KDL-40EX505.

Hi, I'm new here but am glad to have found Serviio. I have just bought a new Sony KDL-32EX713 Bravia TV with DNLA. I use a couple of Windows 7 PCs to record TV using Media Center and really want to be able to play this via the new Sony using DNLA. Windows Media Player does a very poor job of transcoding these .wtv files. Can I add my name to the list of those wanting transcoding of .wtv files on Serviio? Is there a planned date for this?

Nick.

[zip]

can you provide a ffmpeg -i <WTV FILE>

Hi Zip, there is an ffmpeg -i from brotherjohn in this thread. I will try to produce another one today but don't know how yet!

Nick.

I have produced an ffmpeg output:

I don't think this is going to help as there is no video information included. I think your best bet is to record a .wtv yourself using Media Center and try it out.

attachment is missing.

What attachment is needed? I have included the ffmpeg output above.

Nick.

Is there another tool to find more info about these wtv files as ffmpeg doesn't seem able to decode them.

Nick.

[zip]

Hmm... so video track. Serviio will not recognize this file, I'm affraid. Until FFmpeg provide support for this.

How about using the Win 7 wtv to dvrms conversion service to convert the file first then use ffmpeg to do the mpeg2 conversion for streaming to the target device. The dvrms file would need to be deleted after creation of the mpeg2 file. Is this possible?

Nick.

[zip]

t5he dvr-ms file streaming will be possible, the other one probably not. Don't forget this SW runs on many OSes, not just Windows.

Looks like ffmpeg is on the verge of getting WTV support. The builds at http://ffmpeg.arrozcru.org/autobuilds/ support this container:

I've dropped this ffmpeg version into "Serviio\lib" and added my "D:\Recorded TV" folder to Serviio's list. Unfortunately, the videos still do not get picked up. Is there anything hard-coded in Serviio that would prevent it from attempting to index the .WTV files? I even tried naively renaming the extension to .AVI in hopes that Serviio would index, but no luck.

Is Serviio open source? I'd be willing to get WTV supported.

[zip]

Ah cool. 0.5 comes with very recent ffmpeg build so hopefully it's in there. Do you have a short example I could download to try it out?

Yup, grab a sample at http://goo.gl/XwzJi .

Good news, I was able to playback both OTA HD recordings and cable HW MPEG2-encoded recordings. My approach is very proof-of-conceptish, so I'd still like official support

My steps to test all this out:
- Get ffmpeg from http://binaryinspirations.blogspot.com/ ... pport.html instead of the link I gave in the previous post. This version fixes/works around the "non-monotone timestamps". We will call this ffmpeg-real.exe.
- Create a ffmpeg.exe proxy that adds additional command-line flags before it delegates to ffmpeg-real.exe. It also re-writes the response from ffmpeg-real.exe to Serviio. The additional flags are "-fflags genpts", and the re-writing was replacing the "wtv" container with "matroska,webm".
- Use the Samsung C-series TV/player profile, since it calls ffmpeg with the flags to change the container to mpeg2ts instead of mkv.
- Rename the .wtv file to .mpg, just so it passes Serviio's file name filter.

I hope this helps, and I look forward to official support (The renaming from .wtv to .mpg is preventing me from actually using this with all my recordings, since I don't think Windows Media Center will like my renaming the files underneath it)

[zip]

I've tried your example with the ffmpeg I have and it successfully remuxed into mpegts. I'll include the support for a next version.
