play video/audio in C# application

[Ryan Liu]

Hi,

I want to play Audio/Video in my C# application(standlalone, not web
applicatoin). The source of multimedia may in different formats and decided
by the end user, which I have no control.

My question is -- which is the best approach to add multimedia capability to
my c# application, to support most possible formats, and make it easiest for
the end user(e.g. does not need convert before play it)?

I download DirectX SDK, I also heard Flash video/audio now is widely used.
And seems DivX player supports many type of video format, including real
format(*.rm).
Seems DirectX only plays uncompressed audio file and for video, it does not
support real format(*.rm).

So what is the best approach? Any input is highly appreciated.

Hello, Ryan!

Playing video using DirectX can be pretty simple.

Ryan,

Real is a problem with most video players, as far as I know, as there
isn't a codec out there for Windows Media players. You could try and use
the Real player, but I am not sure that it can be embedded in your app.

What it comes down to is that whatever player you choose to embed in
your app, you have to have the appropriate codecs for the media format that
you want to play.

I would be very cautious if you are distributing your app, not to
install codecs for video types over the user's preferences. Video codecs
can be a tricky thing, and I've found that I have come to loathe programs
that install codecs without my knowledge or (explicit) approval.

I'm not aware of a codec that supports Real streaming in WMP, but
there is Real Alternative, which allows for playback of many Real
formats in
WMP.<http://www.free-codecs.com/download/Real_Alternative.htm>

Note that if you can figure out a way to embed the Media Player
Classic (included in the above download), that will stream Real format
without having the Real player. Of course, that still requires a
different component than the regular DirectX supported on.

Personally, I wouldn't worry about supporting Real. There are too
many reasons to avoid Real anyway; the less third-party applications
do to support it, the better. Just my opinion, of course.

I would like to heartily agree with this advice. You'd think a video
codec would just do one thing: encode or decode a specific video
format. Unfortunately, there are lots of situations where one codec
tries to handle a format handled by some other codec already
installed, causing conflicts in software that expects a particular
codec to be handling a particular format. Yes, this is all due to bad
design on the part of the codecs and the dependent software, but it's
a fact of life. Don't make things worse by not giving the user
complete control over how your application manages the codecs.
