User ooris has made the simple and user friendly WMV Converter utility for quick remux+convert WMV HD streams into a NMT friendly format, without loosing the 5.1 audio.
It will convert a WMV container with VC1/WMA Pro 5.1 to a MKV container with VC1/AC3 5.1. Video stream is copied, the audio stream is converted. Conversion in one step, as fast as copying your WMV file.
Update 03/01/09: Minor usage improvements.
Version 0.21: Download.
Feedback for improvement is welcome:
- Windows: tested on XP and Vista. You need to be an administrator when installing!
- NMT firmware with MKV/VC1 support
- Haali Media Splitter
Additional notes from the author
There seem to be no real problems with the tool. Please report other experiences. Incidentally filter problems when experimenting with the filters, reinstalling them fixes the problem. Others mention stuttering or playback problems, these problems are on other Media Players, Popcorn Hour seems to have no problems.
Solution for non-PCH players maybe remuxing with tsMuxeR to a .ts container (don't forget to set the right frame-rate)
There are a lot of HD movies out there in a WMV container containing VC1/WMA Pro 5.1 streams. Unfortunately there are not so many viewers with a receiver supporting WMAPro 5.1 streams.
But I want to hear that chopper from my left back to my right front!
There are a lot of tricks with several utilities to convert the WMV file. But they are not user friendly. Also now and then there is a audio-sync issue Sad
Basicly there is a very simple solution. Use directshow to open the file with the default DMO decoder, convert the WMA Pro stream to AC3 with a directshow filter and mux the audio stream with the VC1 stream in a MKV container with the Haali muxer filter.
It's fast, no sync issues and no handling with thousand different tools.
Again unfortunately there does not exist a tool which can do that for me. And when there is a tool which looks like it, it does not open the audio stream in 5.1 but sadly downmixes it to stereo.
Opening the audio stream in 5.1 is also very simple. All there is to do for the application, is to let the DMO audio filter know to use the _HIRESOUTPUT option. It enables the filter in multi channel mode.
I have a little programming experience and managed to make a small 400K utility that does the trick for me.
It actually is a wrapper to open the WMV file, make the right FilterGraph en output to the new MKV file. It uses the basic Microsoft filters (ASF reader en DMO WM Audio), MatrixMixer for the right channel mapping, RadScorpion's Monogram AC3 Encoder and Haali Media Splitter for Muxing.
I've converted several WMV's and everything looks ok. I manage to convert the file in the time and handling (open file and go) of just copying the file.
