s6410解码问题---linux
我使用的友坚的UT-6410开发板,linux内核版本是2.6.28,7英寸LCD。我使用友坚自带的MFC测试程序(他们不提供源代码)UT_MultiMedia_test_800_480,能正常解码。我到网上下载了Multimedia_DD,编
译通过,拷贝在开发板上运行,出现“Size is too big to be supported”错误。后发现错误在
urbetter-linux2.6.28-v1.0\drivers\media\video\samsung\post\s3c_pp_6400.c下,
// S3C6410 support that the source image is up to 4096 x 4096
// and the destination image is up to 2048 x 2048.
if ( (temp_src_width > 4096) || (temp_src_height > 4096)
|| (temp_dst_width > 2048) || (temp_dst_height > 2048) )
{
printk(KERN_ERR "\n%s: Size is too big to be
supported.\n", __FUNCTION__);
mutex_unlock(h_mutex);
return -EINVAL;
}
但是,我的视频文件时三星自带的,不可能超过4096 x 4096,后来我把这段代码注释掉,能运行,但
是出现黑白屏。我以为是友坚编译的内核出问题,我自己又编译了一次,还是出现同类问题,但是,
友坚自带的UT_MultiMedia_test_800_480测试代码,却正常。郁闷!
我的测试代码如下(三星的,我没有修改)
