convert wmv to mp4?

I'm looking around on the web for ways to convert wmv files to mp4. So
far the most common solution seems to be ffmpeg but when I try that it
doesn't seem to understand the video files. The most common type of
comment people give is that this should be straight forward if 32-bit
codecs are installed. I'm running 64-bit and don't see what flags I
might need to set to get that?

There is a library (libwmf) which advertises the ability to do this
but I don't seem to be using it in any application right now:

* media-libs/libwmf
Available versions: 0.2.8.4-r4 {{X debug doc expat xml}}
Homepage: http://wvware.sourceforge.net/
Description: library for converting WMF files

mark [at] c2stabl ~/WMV-Test $ equery depends libwfm
* These packages depend on libwfm:
mark [at] c2stabl ~/WMV-Test $

Anyone doing this successfully today or what to suggest how to do this?

Thanks,
Mark

What you need is likely a combination of 'w32codecs' (which I expect
is an ebuild somewhere) and multilib.

Unfortunately, I don't have a Gentoo box I can ssh into any more, at
least until inara and/or kaylee are fixed. But I did have this kind of
thing working on them previously.

That's what I remembered but I don't even see that available here:

mark [at] c2stabl ~ $ eix w32codecs
No matches found.
mark [at] c2stabl ~ $

I was thinking maybe it got incorporated into something else.

You almost got it:

$ eix -c w32
[N] dev-util/w32api (--): Free Win32 runtime and import library definitions
$ eix -c win32
[N] media-libs/win32codecs ((~)20071007-r4): Windows 32-bit binary
codecs for video and audio playback support

It's also a use flag for vlc and mplayer (that's for my setup,
probably other players support it too), it will pull the package for
you.

Firstly, .wmf files and .wmv files are radically different.

Secondly, mencoder should be able to handle such a conversion quite
easily. Something like:
mencoder ./input_file.wmv -o ./output_file.mpeg
might do the job without further ado.

I believed that upstream mplayer considered the win32codecs USE flag (or the equivalent --whatever build-time flag) to be depreciated.

AIUI win32codecs, as per the description, uses Microsoft *binary* blobs to do the decoding. If I `emerge -f win32codecs` and look inside the tarball, I see a bunch of .dll files.

I believe that mplayer will just use its own open-source decoding code in the absence of this package.

I am certainly able to play back .wmv files here without win32codecs installed. Admittedly, I'm using xbmc to do that, and haven't recently tested using VLC or mplayer, but I would avoid installing that package unless I was sure I needed it.

It's worth telling us *why* you want to do this. It may be better if you can avoid this conversion.

.mp4 is a container format and wikipedia tells me that WMV is a codec, but that .wmv files are usually WMV codec wrapped in an ASF container.

Since .mp4 video most always means h264 encoding, this means slow and dirty transcoding, which will inherently cause loss of video quality. You want to avoid transcoding if you can.

There are containers, and there are codecs. Containers organize and
schedule multiple media streams (be they audio or video) to be played
simultaneously in a synchronized fashion. Codecs, by contrast,
actually encode or decode media streams from one bitstream to another.
(Typically for compression purposese).

WMV, mp4, WAV, etc. are all names given to container formats. WMV
might contain h264 internally, or it might contain one of the
"Microsoft Video" codecs, or it might even contain MPEG or MPEG2. And
any of a number of different codecs.

You use a muxer to pack audio, video and text streams into a
container, and a demuxer to split them back out. mplayer, ffmpeg,
libavcodec, vlc and friends...they're all going to have good support
for just about any *container* format you might see; container formats
are easy to reverse-engineer.

The w32codecs package is about being able to decode the
patent-protected and/or not-yet-reverse-engineered *codecs* that you
can't easily get without having the DLL files from a Windows box.
Sometimes there are open-source alternatives. Sometimes there aren't.
Sometimes that's because of patent issues, sometimes that's because
there aren't enough useful samples, and sometimes that's because
nobody cares about a codec nobody's seriously used since 1997.

Can you play the WMV?

The "wmv" extension usually indicates an ASF container, and the ASF
container can have DRM. I see them every once in a while, and
ffmpeg/mplayer have no idea what to do with them.

Hi Stroller,
I subscribed to a trading service that provides 6 1/2 hour videos
of the day's market action with audio commentary for each trading day
of the week. I like this trader who does the commentary so after the
market closes I'd like to review what he thought about the day's
action. These files are available only in wmv format. They play fine
inside of a Windows VM using Windows Media Player on my Gentoo box but
I'd prefer to be able to review them in Linux using xine or some other
app.

The quality of the video and audio isn't real high to begin with. 6
1/2 hours and they only run about 50MB each. I don't think converting
to mp4 would cause me much concern. Additionally if they are mp4 I
could watch them on my Kindle Fire.

So far I've been unsuccessful with the mencoder suggestion. I'll
keep plugging away as I think I'm done with trading today anyway. Big
move. Caught most of it. Good to take a few minutes off.

Cheers,
Mark

I Cannot play the files on my Gentoo box using Linux. No player that
I've tried so far - xine, mplayer, dragon player in KDE - none of them
play these files. However I can play the files within a Win7 VM on
this machine which is what I've been doing this morning so far. I sort
of doubt the DRM restriction on this stuff. The web site asks
subscribers not to farward these to their friends, etc., and says
subscribers are on the honor system. They appears to be simple
recordings of of his screen and audio coming from an inexpensive mic.
Nothing more.

I just got access to these files today so until this morning I didn't
even know what format they'd be in.

What do you get if you try 'midentify' (from mplayer) or 'midentify2'
(from mplayer2)?

Actually, WMV appears not to be a container format - but a family of codecs.

Apparently the .wmv files we see distributed on the net are most always WMV codec video contained in a ASF container.

http://en.wikipedia.org/wiki/.wmv

I don't believe I've ever encountered a .wmv file containing h264. One probably wouldn't actually notice, in normal use, if one did receive such a file, assuming it worked when one clicked on it.

However I find it extremely unlikely to imagine anyone putting h264 in a .wmv file (or an ASF container). We all commonly put h264 in .mp4 or .mkv containers.

I'm pretty sure we're able to play back WMV7, WMV9 / AC-1 videos without these binary decoders. It's probably not very useful to talk about codecs "nobody's seriously used since 1997." I *am* pretty sure that upstream mplayer *do* generally say "don't bother with the win32codecs". The goal here to to get Mark's video playing, and he's given no indication it's some old file he found on a 1998 system.

Ah, so no good alternative, then, and you probably don't care so much about video quality, as long as it's watchable.

It might well be worth trying these win32codecs, then - setting the USE flag in mplayer and re-emerging. I wouldn't hold my breath, but it's worth a go. He's probably using some MS screencast software.

Expanding a bit I copied one of the files to a test directory to play
with. It seems smplayer will actually play the audio but won't display
video. midentify gives some data. When I look at the ffmpeg info it
seems to me it's also having trouble with the video portion. At least
it seems to understand the audio portion.

I'm guessing the pivot point here is the video format code:

ID_VIDEO_FORMAT=MSS2

Re: convert wmv to mp4? [In reply to]

Mark,

I have about every plugin/codec installed that I could find. Is this
video publicly available? If it is, I'd be glad to download it and see
what I can come up with. If not, you could email it to me, off list of
course, and let me play with it. I might be able to get something out
of it and let you know what I have installed to make it work, IF it
works here.

Let's not forget that HUGE USE flag line I have. ^_^

Technically they're private but it's not like sharing one file from a
month ago to one person somewhere is going to cause anyone any great
pain. (IMO only...)

Before I'd waste any more time in the Gentoo community, unless someone
_really_ wants to work on this off list, I'll probably look for
possible open source or demo programs I could run in the Win7 VM. It's
not important to me where I do the conversion - just that I get them
converted.

I found a web site that does it here:

http://www.mediaconverter.org

It's been grinding away on the first file for 20 minutes and it's
about 30% of the way done. If that works it looks like it supports
batch conversion and could just let it run unattended. It's slow, but
that's not important to me really.

Thanks,
Mark

You've never been deep into AMVs, I take it. If a codec can be shoved
into a container, I've probably had a sample of it at one time or
another.

Actually, a lot of upstream hacks on stuff for reasons ranging from

the blogs.

Sure. But when I give an explanation, I give background. Give a fire,
teach to make a fire...Gentoo tends to be far more about teaching to
make fires than simply providing them. Though sometimes it uses you
for kindling.

Notice the (-win32codecs) flag. Seems to me (on this system anyway)
they are hard masked off? I tried adding the flag to package.use but
emerge won't enable the darn thing...

I'll try another system after the market closes and I have some time.

You need to unmask the USE flag first, by adding -win32codecs
to /etc/portage/profile/use.mask

If he is using amd64 he can't use win32codecs unless he uses a 32-bit
mplayer/ffmpeg. AFAIK.

I think he would still need to compile a 32-bit mplayer/ffmpeg (in a
32-bit chroot) to be able to make use of them. Multilib would let him
run 32-bit mplayer or ffmpeg binaries (which themselves would be able
to use the 32-bit DLLs). But I don't think 64-bit mplayer/ffmpeg can
call 32-bit DLLs.

There is an amd64codecs package containing the 64-bit codecs, but it
has been masked and made obsolete by the fact that mplayer/ffmpeg can
natively do most (or all?) of those codecs these days.

And presumably for all the same reasons, if I cannot play them I
cannot convert them.

Ah, a world full of unspecified, proprietary vendor specific file
formats hidden in old dlls... Ain't it a fine world we live in?

Sort of painful to start maintaining a 32-bit chroot just to handle
this sort of thing. I suspect there's some freeware for the Windows
world that might allow me to do the conversion in a VM. I'll start
looking for that. The web site that advertised conversion didn't work
as it bombed out after an hour.

Maybe there's some simple binary install I could do - Fedora or
Ubuntu, etc. - but my concern there is that those binaries might not
play well inside my 64-bit Gentoo environ...

Mark

There used to be a 32-bit mplayer-bin package in portage that would
have made it simple, but that disappeared some time ago.

If you can find a statically-linked 32-bit mplayer somewhere, and
emerge the win32codecs package on your machine, I think it has a
chance of working.

Actually, going back to the title of the thread, I don't need to watch
wmv files in 64-bit. I really only need to _convert_ them to mp4 so
that I could watch them using xine, etc. or externally on the Kindle.

Maybe a 32-bit Gentoo chroot that doesn't maintain any desktop or X11,
etc. could work? If I could convert the files at the command line
using ffmpeg in 32-bit then that would be pretty manageable in terms
of Gentoo work, assuming the ffmpeg package can be built as without
any GUI stuff?

I don't muck with multilib explicitly; I have it enabled, but I don't
actively do anything.

How does one appropriately build a 32-bit version of an established
ebuild on a multilib system?

I was just thinking that. I played with a chroot briefly just before
inara and kaylee bit it, and it seemed pretty trivial. Were it me,
that'd be the next thing I'd try. (But then, compiling is cheap for
me)

I think I'll try it in a Virtualbox VM first I instead of a chroot.
That's pretty easy to deal with. Easy to back up. Easy to move to a
different system down the road. No disk partitions, etc.

Biggest issue for me is likely to be that I haven't done a 32-bit
install in at least 6 years. No idea what to watch out for but I doubt
it's any big deal. No idea how the 32-bit VM really does 32-bit when
it's running on a 64-bit processor that's doing 64-bit all the time
but I guess that's why we pay these Intel & Oracle people the big
bucks, right? ;-)

And if I end up needing X in the 32-bit environment for some reason it
will be easy to add that down the road.

It's a real drag about the hassles your machines have been going
through. I hope you get by that soon.

Cheers,
Mark

Actually, it's pretty simple, and works just fine IME. I've run 32-bit
processes on 64-bit systems ever since I started using 64-bit Linux a
few years ago, and it's unavoidable if one does anything on 64-bit
Windows.

For that, I imagine I'd use a TCP socket connecting to localhost. To
put it simply, X network transparency is simply awesome. Your x server
would run in your 64-bit environment, and your client app would run in
your 32-bit environment.

I'm probably going to lose inara to Ubuntu 12.04, unless I get lucky
and manage to properly configure a tiny WYSE box I picked up at a
computer recycling center. If that works, I'm in good shape.

I don't think there's much difference. I've only started doing AMD64 installs in the last year or so, maybe 2 or 3 of them in total, and I don't seem to be doing anything different.

Just google "gentoo quick install guide" and follow that - it's marked as for x86, but I've been following it for AMD64, too.

I follow the same guide for both x86 and amd64. The biggest difference
is the tarball you start with. Other than that, it's pretty much all
the same. Linky:

I'd use a SystemRescueCD image (it's an up-to-date Gentoo 32 bit system)

Hi Michael,
OK, the markets are _really_ boring this morning so while I'm
waiting for grass to grow on my trading platform I did the 32-bit
install in a Virtualbox VM. Booted up fine the first time. Only took
about an hour to get it running, so not too bad. (Made easier by being
able to look at config files on host.

emerge -DuN @world ran in a few minutes and the machine is
up-to-date so I can start looking at maybe ffmpeg or something as a
32-bit app.

For anyone following this thread silently (or looking it up in some
future search) the default settings in gentoo-sources-2.3.12 were
fine. I changed the processor to a Core 2 setting, removed all the
networking devices except for the default Intel devices which are
built in (as that's what the Virtualbox network VM model seems to be
built on) and built in ext3 & ext4 file systems. I used grub, not
grub-static as I usually do and just followed the 32-bit install
guide. Booted perfectly the first time.

The only Vbox trick was to choose the bridged adapter, not the
default NAT device. After I did that networking was up and I was off
and running.

Cheers,
Mark

ffmpeg runs on Windows, why not just use that?
