Mplayer Problem

[Meanie]

I always play videos at 320x240 after using xrandr to adjust the resolution, so I can play videos with or without BVDD.

Higher-res videos do play better in 2.4 betas due to the use of BVDD.

actually, the bvdd only gives you some speed improvements. the big improvement comes from the iwmmxt optimised code by atty. it uses the iwmmxt instruction sets rather than the standard arm4l instruction, or the slightly improved xscale optimisations.

and yes, using the 2.4.20 kernel with bvdd and atty's statically compiled mplayer with iwmmxt gives you the best video performance on the Z.

Should've let the pro answer first...Oh, well.

Slightly OT, but does the "mtune=iwmmxt" give the largest performance boost in other builds, or just mplayer/video-intensive stuff?

compiler optimizations give some speed improvement, but code optimization/enhancements give you imrovements in the order of 10 or more vs mere compiler optimization, but of course, both combined, ie compiler optimization and code optimization gives the best results as seen in atty's mplayer build.

Hopefully this doesnt open old wounds, but an enterprising openzaurus user wrote a -vo pxa output for mplayer that works with 2.6.X CXX00 kernels using pxa overlays.

In other words it does the same as BVDD.

Anyway hopefully some enterprising pdaXrom developer will look in OE under packages/mplayer/files for the patches.

oh this is great news! hopefully someone will look into it...

Alright, I'm looking into it, but I have a few questions:

1. Should I use the latest build or the latest release of MPlayer (source snapshot, SVN snapshot, or RC1?
2. Should I apply the patches only for the build I'm using or all of them (probably a dumb question)?
3. Should I cross-compile or compile natively?
EDIT: 4. What (if any) CFLAGS should I use?

[XorA]

Well if you look at my mplayer_XXX.bb files you will see what environment I used to compiling mplayer in OE. Seems to compile and work fine in armv4, armv5, and iwmmxt modes. For CXX00 I would suggest iwmmct "-mcpu=iwmxxt -march=iwmmxt -mtune=iwmmxct" in CFLAGS.

You should be able to patch up either RC1 or latest SVN, OE does both. I have heard rumours that latest svn contains some more arm optimisations that rc1 but I havent benchmarked.

Cross compiling would be fine, mplayer handles this without problems.

Thanks...I'll get looking at it harder now.

A couple more questions:

Should I use my normal GCC, or the cross environment?

Configure fails when looking for inttypes.h. How can I make it find it? It will find it if I get rid of the flags "-fomit-frame-pointer -mcpu=xscale -pipe", but then it says its optimizing for a Pentium M.

I'm trying to build with the latest SVN source.

The cross environment. But its been so long since I did a build outside of OE don't ask me what the magic to pass the configure is.

[XorA]

Actually something along the lines of this. Pulled directly from the OE build.

                    --build=x86_64-linux \
                    --host=arm-angstrom-linux-gnueabi \
                    --target=arm-angstrom-linux-gnueabi \
                    --prefix=/usr \
                    --exec_prefix=/usr \
                    --bindir=/usr/bin \
                    --sbindir=/usr/sbin \
                    --libexecdir=/usr/libexec \
                    --datadir=/usr/share \
                    --sysconfdir=/etc \
                    --sharedstatedir=/usr/com \
                    --localstatedir=/var \
                    --libdir=/usr/lib \
                    --includedir=/usr/include \
                    --oldincludedir=/usr/include \
                    --infodir=/usr/share/info \
                    --mandir=/usr/share/man \

arm-angstrom-linux-gnueabi needs to be changed to whatever the system is called under pdaXrom cross compiler.

I got it to start compiling, but now it quit. Here's my configure command and error:

Yes, feed it the right -I and -isystem commands so that it doesnt search in /usr/include for include files.
