[MPlayer-users] Couple of newbie questions...

[Philip Prindeville]

Hi.

New on the list (though I suspect now is not the best time to be
joining it... oh, well)...  and I had a couple of questions.

First, I'm seeing the dreaded "too many packets in video buffer"
message when trying to play the Brian Wilson "Smile" DVD.  See
below.  If I play it differently as:

% mplayer dvd://3 -ac dvdpcm -aid 160 -ao alsa:device=hw=0.0

(and via analogue line-out instead of via SPDIF/RCA) then it works.
I suspect that the problem actually has nothing to do with the video
stream at all, and is a decoder issue (however, both hwac3 and a52
decoders have the same issue).

Second question, how does one get DVD menu navigation to work?
I can play individual titles, but not see the top-level menus to get
around the various titles on most DVD's.

Third, under Windows, the same hardware (a MSI-7142/K8MM-V
motherboard, AMD Athalon 64, 1GB, Sony DVD-RW DRU-800A,
NVidia GeForce 6200 video card, etc) seems to be a lot better at
reading the same DVD's than Mplayer-1.0pre7 is on FC3.  I suspect
that Mplayer isn't setting the DVD's error-correction strategy to be
as aggressive... but I couldn't find what the settings were using
"hdparm", so I'm not even sure that Linux let's you tweak this.

Lastly, how does one encode a DVD in "fat" format (with all camera
angles, all subtitle info, all audio tracks in multiple languages... 
etc. all
layered in parallel)?  That is, I might want to rip a DVD onto a hard
disk now, but might not know until later if it will be watched in PCM/stereo
or DTS 6.1 until later, and whether it will be watched with english captions
or spanish subtitles, etc.

Thanks,

-Philip

Here's the debugging from playing Brian Wilson's "Smile" with hwac3
(via the builtin Southbridge Via 8237R and Via 1617A codec)...  And
yes, I tried -ni and it made no difference.

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
