Windows Phone 7

[Rickwally]

Hello, I've been using PMS for quite a while now and some days ago I started working on an App for Windows Phone to stream my videos to it through PMS.
At the moment PMS recognizes the windows phone client and I can reproduce all the videos already correctly encoded, the problem is that I can't understand how to set the correct transcoding options for the others.
Windows Phone supports .mp4 and .wmv files as described here.
If I understand correctly there's no way to transcode using as video codec WMV3 so wmv is excluded, using a command like this:

Code: Select all

"C:\Program Files (x86)\PS3 Media Server\win32\ffmpeg.exe" -sn -i "D:\input.avi" -vcodec libx264 -f mp4 -acodec aac -strict experimental -g 1 -qscale 1 -qmin 2 -ab 320k -threads 8 -muxpreload 0 -y "D:\output.mp4"

I obtain a correctly transcoded file, how can I make PMS produce something similar through the .conf file?

At the moment I have this:

I hope someone can help me out

[Rickwally]

I'm starting to think that is impossible. The currently supported options for TranscodeVideo are very limited, I even tryed to set

Code: Select all

TranscodeVideo=MPEGTSAC3

and

Code: Select all

CustomMencoderOptions = -ovc x264 -x264encopts qp=20:level_idc=31:threads=8:global_header:bframes=0 -lavcopts acodec=libfaac:aglobal=3:threads=8 -lavfopts format=mp4

Hoping to override the relative options but it is just added in the middle of the others.
I don't know what else can I do. I'd really appreciate some help, at least to know if it's possible or not.

The WMV TranscodeVideo profile (which is currently only supported by MEncoder) is WMV2 video and WMA2 audio in an ASF container, which should work for Windows Phone 7 according to this.

I've updated the PS3 renderer conf to clarify the options.

[Rickwally]

First of all, Thank you for the answer
The WMV profile has a problem, when I use it and try to play any video on the phone, the phone crashes (Not just the media player, the whole OS) and that - togheter with the page I linked in the first post - convinced me that the WMV2 video codec was not supported. I'm just passing the uri to the OS's Media Player so it shouldn't be my fault.
Now, out of curiosity I made a test: I used the exact same mencoder's command that uses pms to encode a video in asf, I put the transcoded video in a pms's shared folder and - I can't understand why - playing it throught pms works.
What is the difference between streaming directly and transcoding&streaming? The data received by the client should be exactly the same right?
I'll try to put togheter a little player with the MediaElement and see what happens.

Apart from this, looking at the generated mencoder command I was wondering if it couldn't be improved.
The threads options is set to 1 while with the other profiles is set to 8 (which corresponds to my setting in the transcoding options).
Mencoder reports that [asf @ 010b9da0]Codec for stream 0 does not use global headers but container format requires global headers so maybe would be useful to add the aglobal/vglobal = 3 options but I don't know much about these things so I'm probably wrong.

[Rickwally]

Even with the MediaElement component the phone crashes, I tryed also to pass to the media player a uri with the correct extension (Changing it to .asf) but nothing changed.
I looked also at what sends back pms in response to a request and got this:

Code: Select all

HTTP/1.1 200 OK
Content-Type: video/x-ms-wmv
ContentFeatures.DLNA.ORG: DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=01700000000000000000000000000000
Accept-Ranges: bytes
Connection: keep-alive
Server: Windows_7-x86-6.1, UPnP/1.0, PMS/1.60.0

And I was wondering if maybe the media player is expeting a mime type like video/x-ms-asf matching the actual container :-\
I don't see anything else that could cause it....

EDIT: No, it's not. Pms's response to the request of the manually encoded .asf file I was talking before is exactly the same except for content-length

Code: Select all

HTTP/1.1 200 OK
Content-Type: video/x-ms-wmv
ContentFeatures.DLNA.ORG: DLNA.ORG_OP=01;DLNA.ORG_CI=0;DLNA.ORG_FLAGS=01700000000000000000000000000000
Accept-Ranges: bytes
Connection: keep-alive
Server: Windows_7-x86-6.1, UPnP/1.0, PMS/1.60.0
Content-Length: 1332055

I'm lost. I think I will pay a visit to the microsoft dev forum. It just can't be that trying to play a media content crashes the entire OS.

Hi

I am doing a similar application in Serviio and have run into the exact same issue. Have you been able to find a solution.

I tried using both MediaElement and the MediaPlayerLauncher and a single time I got the MPL to launch the movie. Any tries after this produce similar results as you are getting - complete phone restart!

Any help is much appreciated.

[Rickwally]

Hi, I'm still trying to understand what's the problem -> viewtopic.php?f=11&t=15168

[chocolateboy]

If the same (fatal) error is also occurring with files streamed by a different media server using a different transcoding engine, it's unlikely to be a PMS issue.

I think I will pay a visit to the microsoft dev forum. It just can't be that trying to play a media content crashes the entire OS.

Did you get a response?

[Rickwally]

Actually I didn't ask since I found a way to limit the crash to the mediaplayer, it is related to the fact that transcoded files are damaged (It still doesn't excuse the crash of the os but that's not my problem now).
Windows Media Player's Transcoding works fine, I'll check with other media servers and see what happens.
