Transplantation of MPlayer on ARM9 (at91rm9200)

MPlayer supports only 16BPP graphics display and does not support 8BPP graphics display, so when the MPlayer program runs on the Development Board with an LCD configured as STN, only sound can be played, graphics cannot be displayed, and when the LCD is configured as a TFT Development Board, You can play both sound and graphics.
1, download and decompression
Go to MPlayer's official website http://www.mplayerhq.hu's homepage and download the MPLAYER-0.93.TAR.BZ2 package.
Cd/work
TAR-JXVF mplayer-0.93.tar.bz2
Check out the Readme and install files to see if there is anything special to declare when you install it, because different versions of the same software sometimes do not have the same method of installation. then enter the./configure--help to see if there are more or less options
2. Source code Bug Resolution
The problem with the header file reference, in particular, is that in both the Libmpcodecs and LIBAVCODEC directories, there is a omission, that both directories of the source files are #incude "Config.h" way to refer to the header file "Config.h", However, the header file "Config.h" does not exist in either directory, and these source files are actually expected to refer to the "config.h" header file in the MPlayer installation package root directory, So we need to manually set up a link named Config.h in both the Libmpcodecs and Libavcodec directories and point to the package root header file in the MPlayer installation config.h directory to establish a method:
$> CD Libmpcodecs
$> Ln–s. /config.h config.h
$> CD ... /
$> CD Libavcodec
$> Ln–s. /config.h config.h
3, cross-compilation
Create a script file in the/mplayer-0.93 directory: Mkall, this script is a compilation script that reads as follows:.
/configure--cc=/usr/local/arm/3.4.1/bin/arm-linux-gcc--target=arm-linux--with-extralibdir=/usr/local/arm/3.4.1 /arm-linux/lib/--with-extraincdir=/usr/local/arm/3.4.1/arm-linux/include/-- Disable-sdl--enable-static--disable-dvdnav--disable-tv--disable-gui--disable-mpdvdkit--enable-linux-devfs
Then execute the./mkall complete configuration.
Then run make
MPlayer source code is very large, and used to many of the third party's library, did not compile a few, it stopped, there are such errors:
./codec-cfg./etc/codecs.conf > Codecs.conf.h
/bin/sh:line 1:/codec-cfg:cannot Execute binary file
According to the online post solution: Check, found codec-cfg This executable file is the first compiled a file, the file is there, how can not be implemented. So manually executed a bit, the system prompts "cannot execute binary file", suddenly remembered, Codec-cfg is compiled on a cross-platform basis, the resulting arm of the code, of course, can not be implemented on the x86, then the first use without Cross-platform compilation of the Way, First compile the MPlayer into x86 code, then reconfigure, simple./configure, make, and then rename the generated codec-cfg to codec-cfg.x86. Then the cross-platform configuration, compile, and so on compiler error stop compiling, will codec-cfg.x86 that name as Codec-cfg, and then make
The results of the following error occur:
codec-cfg.c:in function ' parse_codec_cfg ':
codec-cfg.c:501: ' Builtin_video_codecs ' undeclared (in the This function)
codec-cfg.c:501: (Each undeclared identifier are reported only once
Codec-cfg.c:501:for each function it appears in.)
codec-cfg.c:502: ' Builtin_audio_codecs ' undeclared (this function) requires that the current makefile be modified to
$ (CC) $ (cflags)-G codec-cfg.c mp-msg.c-o-----
The parameter $ (CC) in is changed to GCC, by compiling.
After the compilation is successful, the MPlayer file is generated in the/mplayer-0.93 directory, which is the MPlayer media playback program.
#cp mplayer/tftpboot Copy the code to the specified directory
4. Download and run
Launch the Arm-linux on the 9200 Development Board to run the command on the host:
#mount-O nolock-t NFS 202.200.93.154:/tftpboot/mnt
To run on minicom:
Cd/mnt
./mplayer
The following message appears:
