[DEV] Compiling mplayer

Hi @all,
i want to compile the mplayer for Android.
The only "How-To" i found is this.
Maybe someone with more experience in cross-compiling can give me some more hint.
thanks
peter

Take a look at that, can probaly be helpful

Did you get it to run?

mplayer run's.
But i have some trouble to set VSCREENINFO.
Maybe wrong video fromat.
So I have to check some different video's.

what about audio? looking at some posts in the MPLAYER discussion VSCREENINFO issues appear to be something to do with framebuffer of the kernel.

I've been trying to get audio working, although in a Magic 32B, but I have failed so far.
Do you Hero owners see /dev/dsp or /dev/snd0 ?
Do you get any audio at all? If so, using what device?
From the very limited information I've managed to get so far, Dream owners do get sound, though I have no idea how and why.
I've used the how-to mentioned in the first post, no success so far.

Perhaps this helps: read-write access for /dev/msm_pcm_out
So chmod this device file and use it as audio out?
I'm actually curious about how a native linux app would render video on android. There is no X so framebuffer would be the only way. But then, how do you get user in/output?

status mplayer crosscompilation
@all
follow things i have tryed:
- Crosscompiling svn-version mplayer, there i have some segmentation fault's.
doesn't work
- Crosscompiling Mplayer1.02 (old version) there i have trouble to set VSCREENINFO.
So it takes time
If anybody have some hints, about crosscompiling, feel free.

I managed to compile a working (by working I mean no segfault ) version of SVN-r29796 with the following config:
./configure --enable-fbdev --host-cc=gcc --target=arm --cc=arm-none-linux-gnueabi-gcc --as=arm-none-linux-gnueabi --ar=arm-none-linux-gnueabi-ar --ranlib=arm-none-linux-gnueabi-ranlib --enable-static
The resulting binary can be found here:
http://www.megaupload.com/?d=142QK29B
Together we can solve this, sandmen
What we need now is a Dream user to confirm that audio works on that hardware...

@Djhg2000
you can play a video without sound?

No, I get the VSCREENINFO error. It does decode video though if I use "-vo null -ao null", but what probably won't get us anywhere...
I've heard the VSCREENINFO problem is a kernel bug, can anyone confirm this?
I don't have the time to look into it now, but maybe we can make a patch to workaround the problem?
Edit:
It seems like this piece of code in libvo/vo_fbdev.c is causing the problem:
Code:
if (ioctl(fb_dev_fd, FBIOGET_VSCREENINFO, &fb_vinfo)) {
mp_msg(MSGT_VO, MSGL_ERR, "Can't get VSCREENINFO: %s\n", strerror(errno));
goto err_out;
}
These lines can be found at 685-688 in r29796.
The problem is that my C skills are very limited and I have no idea what "&fb_vinfo" should be... C coders please help?
Typing "ioctl FBIOGET_VSCREENINFO" returns "ioctl: too few arguments".
Typing "ioctl FBIOGET_VSCREENINFO 0" returns "cannot open FBIOGET_VSCREENINFO"
From the information I can gather, ioctl seems to be a tool to pass instructions directly to drivers?
Yeah, it finally seems like we're getting somewhere

I've tried this, "-ao oss:/dev/msm_pcm_out" gives "Can't set audio device /dev/msm_pcm_out to s16le output, trying s16le...".
"-ao pcm:file=/dev/msm_pcm_out" hangs MPlayer at the "Starting playback..." message.
"-ao pcm:file=/dev/msm_pcm_out -v" hangs MPlayer with the line "Increasing filtered audio buffer size from 0 to 65536".
So yes, it might be the right device, but I can't get it to work.
Perhaps you could download the binary and see if you get different results on a Hero?

@Djhg2000
Did you get the "get VSCREENINFO" error or the "put VSCREENINFO"

sandmen said:
@Djhg2000

Click to expand...
Click to collapse
Wow, do I feel stupid
Of course it's the put VSCREEN error, here is the correct code from libvo/vo_fbdev.c:
Code:
if (ioctl(fb_dev_fd, FBIOPUT_VSCREENINFO, &fb_vinfo)) {
mp_msg(MSGT_VO, MSGL_ERR, "Can't put VSCREENINFO: %s\n", strerror(errno));
if (fb_tty_fd >= 0 && ioctl(fb_tty_fd, KDSETMODE, KD_TEXT) < 0) {
mp_msg(MSGT_VO, MSGL_ERR, "Can't restore text mode: %s\n", strerror(errno));
}
return 1;
}
This is at lines 814-820 in r29796.
It seems like the problem mostly remains the same.
However, I can't debug it properly (yet!) due to my lack of skills in C .
I'm making slow progress in understanding the real problem, but at least I'm learning some C while I'm doing it
Edit:
I've looked through the sources and I just can't figure it out:
Code:
static struct fb_var_screeninfo fb_vinfo;
means that fb_vinfo should look like fb_var_screeninfo, right?
But fb_var_screeninfo itself (defined in linux/fb.h) looks like this (copied directly form android kernel git tree):
Code:
struct fb_var_screeninfo {
__u32 xres; /* visible resolution */
__u32 yres;
__u32 xres_virtual; /* virtual resolution */
__u32 yres_virtual;
__u32 xoffset; /* offset from virtual to visible */
__u32 yoffset; /* resolution */
__u32 bits_per_pixel; /* guess what */
__u32 grayscale; /* != 0 Graylevels instead of colors */
struct fb_bitfield red; /* bitfield in fb mem if true color, */
struct fb_bitfield green; /* else only length is significant */
struct fb_bitfield blue;
struct fb_bitfield transp; /* transparency */
__u32 nonstd; /* != 0 Non standard pixel format */
__u32 activate; /* see FB_ACTIVATE_* */
__u32 height; /* height of picture in mm */
__u32 width; /* width of picture in mm */
__u32 accel_flags; /* (OBSOLETE) see fb_info.flags */
/* Timing: All values in pixclocks, except pixclock (of course) */
__u32 pixclock; /* pixel clock in ps (pico seconds) */
__u32 left_margin; /* time from sync to picture */
__u32 right_margin; /* time from picture to sync */
__u32 upper_margin; /* time from sync to picture */
__u32 lower_margin;
__u32 hsync_len; /* length of horizontal sync */
__u32 vsync_len; /* length of vertical sync */
__u32 sync; /* see FB_SYNC_* */
__u32 vmode; /* see FB_VMODE_* */
__u32 rotate; /* angle we rotate counter clockwise */
__u32 reserved[5]; /* Reserved for future compatibility */
};
Which is identical to the same struct in Ubuntu's kernel tree?
My conclusion so far is that one of these parameters are unsupported by the HTC Magic's graphics driver, but not the HTC Dream graphics driver?
I have no idea why the driver would even differ between them; they both use the same graphics chip, don't they?

I assume you have root ?
try
chmod o+rw /dev/msm_pcm_out

Already tried that, I usually use root when debugging inside of Android, but not even "chmod 777 /dev/msm_pcm_out" helps.
I noticed there might be some relevant libraries in android:
/lib//libaudio.so
/lib/libhardware.so
/lib/libhtc_acoustics.so
/lib/libmedia.so
/lib/libmm-adspsvc.so
/lib/libopencore_player.so
/lib/libsoundpool.so
/lib/bluez-plugin/audio.so
Surely at least one of these libraries can provide a way to output audio?
Except maybe that bluez thing

I want to be a beta tester. My device is HTC Dream (g1).

1: pcm is the way to go. If you run mplayer -ao help, does it list pcm?
2: you can try compiling mplayer along with support for a sound server like pulseaudio, which would mean that you would need to add that package too...

Great, finally a Dream user (maybe thread should be moved to the Dream Development sub forum, as that's where people look for general android discussions).
Anyway, it's publicly available here:
http://www.megaupload.com/?d=142QK29B
Version SVN-r29796 for now, will probably upgrade later and post link here.
Save it to a SD card and use 'sh mplayer mediafilegoeshere.example -ao oss:/dev/msm_pcm_out' and post the results here.
Since you have a HTC Dream, it would be great if you could confirm it working/broken without the '-ao oss:/dev/msm_pcm/out' part.
Thanks for your help

[Q] root_plug

Not sure if this means anything, just throwing it out there, but i was going through file for froyo on the evo, original file name "supersonic-2.6.32.15-g746f4f0.tar" and found a file named root_plug-notepad, now i'm only guessing, but is this how they are blocking us from being able to root our device, or am i just guessing outta my arse.

DO NOT FLASH THIS FILE!
http://www.multiupload.com/72EE5VK58S

hmm.. i'm not making any sense!
uhm.. the problem lies with the write command..
are you sure the boot.img is in the /tmp directory on your phone?

I'll have a quick look for you as well.

"boot.img" makes me suspect you are trying to update in the HTC way. It's likely that the CM devs haven't posted the info to allow you to build a fully flashable ZIP yet. WesGarner tweeted recently that he bricked his phone trying a dev build, so be careful.

Mail from wes:
Can't use raw image write
Since boot is the last to flash use my build kernel script which will flash the kernel using redbend

You seem to be missing all of your proprietary files..
You should check in with noobnl on your bulding technique.

So finally new devs are trying to make this port possible? Hope it will be soon as anyone else!

Solved .[eVC++] How to use "srand" function?

Hello.
I want to ask some skilled developers,how to use "srand" function?
I found in help this:
Code:
/* RAND.C: This program seeds the random-number generator
* with the time, then displays 10 random integers.
*/
#include <stdlib.h>
#include <stdio.h>
#include <time.h>
void main( void )
{
int i;
/* Seed the random-number generator with current time so that
the numbers will be different every time we run.
*/
srand( (unsigned)time( NULL ) );
/* Display 10 numbers. */
for( i = 0; i < 10;i++ )
printf( “ %6d\n”, rand() );
}
Problem is,when I use this example,I get errormessages:
CNS.obj : error LNK2019: unresolved external symbol time referenced in function "void __cdecl PrepareWheel(struct HDC__ *)" ([email protected]@[email protected]@@Z)
ARMV4Dbg/CNS.exe : fatal error LNK1120: 1 unresolved externals
Without this function,function "rand" returns all the time same sequence(as we know).
I am using Embedded Visual C++ 4.0 for PocketPC app development.
That's for now,thanks,Tomas.

[Q] Regarding USB audio (source code help)

By using the GlaDOS kernel and Usb audio recorder ROOT, I was able to listen to music with my USB headset, however I really would like a way to implement it into the kernel or the OS so I can reroute media sound to my headset with other apps.
Here's the source code of the driver... Maybe someone with more knowledge than me will be able to implement it or maybe point me in the right direction.
