mplayer doesn't work on cryptographic filesystem


I'm using a 3des cryptographic filesystem that shadows
a real disk partition and the encryption/decryption is
handled by an NFS-like daemon, via its mountpoint.

/home/me/locked/

shows encrypted crap

/secure/locked/

shows real files once I enter the cattach command with
the correct key.

the files in the secure area are
readable/editable/whatever by typical unix/linux
commands....however, mplayer says "file not found"
when attempting to play an avi file stored in the CFS.

if I enter

# strace mplayer /secure/locked/mymovie.avi 

it works,but 

# mplayer /secure/locked/mymovie.avi

does not work...says file not found?

any thoughts why?  what kind of (statting) is mplayer

blank video playback with xv

With an ATI Radeon Mobility M7, mplayer 1.0pre7, and xorg 6.8.2 I'm
getting a blank screen (well, it's slightly blue due to a color key
value of 30 - various settings of color key confirm this - at least
this much is working, sigh).

Is there anything in this output of xvattr that would explain the
blank screen?

Obviously it's not as fast. The point is that it compresses several
times better than intra-only, while still not being as slow as motion
estimation..

Almost all content on DVDs is telecined, not interlaced, so
deinterlacing is rarely correct. Even if it is, pp=md or kerndeint is
your best bet usually. ci and li are completely useless, and lb, l5,
and fd all produce ghosting artifacts. I wrote a document on it a long
time ago and submitted it to mplayer-docs list, detailing why all the
deinterlacers suck... dunno what happened to it. :)

Of course.  But in this case, disk space isn't much of an issue, and CPU
power is.

I'm using Slackware 10.0 and never had any problems.

Yes, but it would seem MPlayer thinks the world is 75dpi, OR, that the
relationship Point <-> Pixel is a fixed ratio, which requires you to tweak
settings quite a bit, and still not get font scaling "quite right" ...

Recording streaming baseball radio on mlb.com

I'm considering joining the gameday audio subscription
provided by mlb.com 

I hope to record the games in mp3 format so I can
listen to them on an ipod. 

Is there a way to do this using mplayer running on Mac
OS X?  I'm not sure if it will handle the audio codec
used and any web authenication. 

Chris.

A/V sync problem from out-of-spec audio sampling rate

I appreciate all of the help I've received on this problem.
I still need to test a mencoder patch (that I've applied and compiled
with, but have not tested).  In the meantime, I'm posting the following
script that will resample audio when the audio is out-of-spec, and not
resample audio when the audio is within spec. 

NOTE script meant to compress raw.dv to dvd grade mpg with
ac3 audio at 4500 video bit rate.

The video compression part is based on transcode's dvtodvd.sh.
I can't use transcode peeled off audio to determine how much the
audio is out of spec because transcode cuts the audio based on the
video (and assumes the audio is within spec).  Hence using ffmpeg
to peel off the audio, ecalength to measure, etc.

THIS SCRIPT IS NOT PARAMETERIZED NOR IS IT INDUSTRIAL STRENGTH.
I AM NOT PROVIDING A SITE/APP SPECIFIC CONFIG SCRIPT.
I AM NOT PROVIDING THE FFMPEG.CFG FILE (FIND AT TRANSCODE SITE).
In other words, won't work at all without a little touch up, no error 
checking
re whether a program is happy or not doing its job, etc.  But it should get
someone started with a solution if faced with this problem.

[[ short explanation of problem -- some DV equip creates out of spec
unlocked audio that becomes apparent when the A/V streams are separated,
compressed, and re-mux'ed together.  Problem  not apparent at beginning of
the video, the A/V creeps increasingly out of sync.  Worst offender 
seems to
be some Canon camera models from a particular time period that created
48008-48009 audio which leads to approx .3 sec A/V out of sync after about

  Thanks for the tip on these plugins. For anyone interested, the
  equalizer in this collection is also really good, and not
  CPU-intensive.

  MPlayer may not be intended for use as an audio player, but it's far
  and away the best thing around, especially for those of us who don't
  like a GUI. :)

  Take care,
  Steve
