mplayer can't play a video file though ffplay does albeit with aberrations

sumeet inani · 07-12-2010, 03:03 AM

I am using ubuntu 8.04
I compiled latest mplayer then

Yeah, mplayer says all sorts of interesting stuff.

Read the RealVideo section of the DOCS!

You did, of course, read the Docs, didn't you? Remind us of what you took from them so we won't have to read them :-D. I would also check where the codecs are: I've seen a codecs dir in /usr/lib, /usr/lib64, and conceivably /usr/local{lib or lib64}. So when I see

Win32 LoadLibrary failed to load: drvc.dll, /usr/local/lib/codecs/drvc.dll, /usr/lib/win32/drvc.dll, /usr/local/lib/win32/drvc.dll

and it may just be you should symlink /usr/local/lib/codecs to your real codecs dir. It may be you should download a pile of codecs!
MNplayer's man page is one of the all time great manpages

It looks like the video was encoded in one of the realplayer video formats. These are closed, proprietary codecs that must be reverse-engineered for decoding, meaning that they often have poor support, especially early on.

It's kind of strange though that ffplay works while mplayer doesn't, since mplayer simply calls on ffmpeg/libav to do the actual decoding.

You might also install the extra binary mplayer codecs installed (a.k.a. win32codecs), if you don't have them already. Your output shows they weren't detected.

sumeet inani · 07-12-2010, 03:44 AM

Before doing './configure;make;' for extracted mplayer tarball.
I had extracted contents of essential-20071007.tar.bz2 into folder /usr/local/lib/codecs

as you said David the H.
I did

Code:

#apt-get install w32codecs

Now i get

From where can I get this drvc.dll ?

business_kid · 07-13-2010, 03:09 AM

Real Player is available for linux, surprisingly.

sumeet inani · 07-14-2010, 04:05 AM

I copied drvc.dll from windows partition (namely /windows/Program Files/K-Lite Codec Pack/Real/Codecs/drvc.dll)

Also
http://samples.mplayerhq.hu/real/AC-.../samplerv.rmvb plays well in mplayer.

Already tried playing the mkv file mentioned above in real player 11.0.2.1744 (GOLD)

I get

Code:

The player does not have capabilities to playback this content
The following components are required
mkv

sumeet inani · 07-14-2010, 06:45 AM

finally I found solution
Just add option '-demuxer lavf' to play the video.

There had to be an answer (http://lists.mplayerhq.hu/pipermail/...ay/080117.html).
I believe mplayer can play everything.

PROBLEM
the audio is not clear ?

The option and all others listed in the myriad search results for "mplayer mkv COOK RV40 sync" (and variations) failed to fix the problem for me. I tried all options, transcoding with mencoder to avi and many other things, but they all failed. Finally, in frustration, I unpacked the MKV into it's component streams with mkvextract from the mkvtoolnix (2.3.0) package and then joined them with mencoder. And voila, it worked.

My conclusion: Mencoder cannot sync the A/V streams from the MKV container properly.
