F1C200s主线gstreamer使用openmax调用cedar硬解码

逸俊晨晖 · 2021-01-07 23:18:48

之前发了个v3s使用gstreamer的插件openmax调用cedar硬解码的主题
https://whycan.com/t_5398.html

不少小伙伴用F1C200s尝试使用遇到了问题
报了个初始化解码库失败的错误
经排查发现是配置libcedarc时要选择一个编译硬解码库的gcc
之前用v3s时这个配置项默认是arm-linux-gnueabihf 恰好是适合v3s使用的gcc
但是在F1C200s就不能用了要进行修改

在修改完以后继续尝试播放发现屏幕显示一片墨绿过一会内核崩溃了绿的我发慌
重启还起不来发现是有和启动相关的库被破坏掉了要重新烧录才行能正常启动

后来排查发现是硬解码输出帧格式的问题（但不至于内核奔溃甚至破坏启动库吧）
我们在用v3s进行硬解码时 openmax是被默认配置为输出YV12 所以v3s用起来没问题但是到F1C200s就不行了 F1C200s只能输出MB32 （详细资料看隔壁硬解码主题8楼 https://whycan.com/t_5429.html）
所以我们只要将openmax配置修改一下再对输出格式做个转换就可以了

下面开始修改内容

1.配置编译硬解码库的gcc
在buildroot配置libcedarc
Target packages ->
Hardware handling ->
libcedarc ->
Arch library select
改成arm-none-linux-gnueabi

2.修改openmax
在buildroot进入目录output/build/libcedarc-master

cd output/build/libcedarc-master

修改源文件omx_vdec_aw_decoder_linux.c

vim openmax/vdec/src/omx_vdec_aw_decoder_linux.c

在结构体类型typedef struct OmxAwDecoderContext增加以下成员
char* pYV12;
VideoPicture CvtPicture;

在函数__liPrepare中
把

pCtx->mVideoConfig.eOutputPixelFormat = PIXEL_FORMAT_YV12;

改为

pCtx->mVideoConfig.eOutputPixelFormat = PIXEL_FORMAT_YUV_MB32_420;

在语句ret = InitializeVideoDecoder(pCtx->m_decoder, 上面一行添加以下内容

pCtx->pYV12 = (char*)malloc(sizeof(char) * pCtx->mStreamInfo.nWidth * pCtx->mStreamInfo.nHeight * 3 / 2);
if(pCtx->pYV12 == NULL)
{
    loge("pCtx->pYV12 malloc fail\n");
    return -1;
}
pCtx->CvtPicture.pData0 = pCtx->pYV12;
pCtx->CvtPicture.ePixelFormat = PIXEL_FORMAT_YV12;

在函数__liDrain中
在logv("*** picture info: w(%d),h(%d),offset,t(%d),b(%d),l(%d),r(%d)",上面一行添加以下内容

RotatePicture(pCtx->decMemOps, pCtx->pPicture, &pCtx->CvtPicture, 0, 32, 32);

将

AlignCopyYV12((unsigned char*)pOutBufHdr->pBuffer,
                                (unsigned char*)pCtx->pPicture->pData0,
                                outDef->format.video.nFrameWidth,
                                outDef->format.video.nFrameHeight);

改成

AlignCopyYV12((unsigned char*)pOutBufHdr->pBuffer,
                                (unsigned char*)pCtx->CvtPicture.pData0,
                                outDef->format.video.nFrameWidth,
                                outDef->format.video.nFrameHeight);

在函数__liGetFormat
把

pCtx->mVideoConfig.eOutputPixelFormat = PIXEL_FORMAT_YV12;

改为

pCtx->mVideoConfig.eOutputPixelFormat = PIXEL_FORMAT_YUV_MB32_420;

在函数__liClose
在if(pCtx->m_decoder != NULL)上面一行添加以下内容

if(pCtx->pYV12 != NULL)
{
        free(pCtx->pYV12);
        pCtx->pYV12 = NULL;
}

3.修改libcedarc 添加格式转换
修改源文件pixel_format.c
vim vdecoder/pixel_format.c
在函数ConvertPixelFormat上面添加一个函数

void MB32_CVT_YV12_(char* pSrc, char* pSrc_v, char* pDst, int nWidth, int nHeight)
{
	int i = 0;
	int j = 0;
	int m = 0;
	int n = 0;
	int k = 0;
	int nMbWidth = 0;
	int nMbHeight = 0;
	int nMbWidth_uv = 0;
	int nMbHeight_uv = 0;
	int nLineStride = 0;
	int nLineStride_uv = 0;
	int lineNum = 0;
	int lineNum_uv = 0;
	int offset = 0;
	int offset_uv = 0;
	int maxNum = 0;
	char* ptr = NULL;
	char* ptr_uv = NULL;
	char* pDstU = NULL;
	char* pDstV = NULL;
	int nWidth_uv = 0;
	int nHeight_uv = 0;
	char bufferY[32];
	char bufferV[16], bufferU[16];
	int nWidthMatchFlag = 0;
	int nWidthMatchFlag_uv = 0;
	int nCopyMbWidth = 0;
	int nCopyMbWidth_uv = 0;
	char *dstAsm = NULL;
	char *dst0Asm = NULL;
	char *dst1Asm = NULL;
	char *srcAsm = NULL;
	char *srcAsm_uv = NULL;

	int bCnt2 = 1;

	nLineStride = (nWidth + 15) &~15;
	nMbWidth = (nWidth + 31)&~31;
	nMbWidth >>= 5;//n 32 width   / 32

	nMbHeight = (nHeight + 31)&~31;
	nMbHeight >>= 5;// / 32
	ptr = pSrc;

	nWidthMatchFlag = 0;
	nCopyMbWidth = nMbWidth - 1;

	nWidth_uv = (nWidth + 1) / 2;
	nHeight_uv = (nHeight + 1) / 2;

	nLineStride_uv = (nWidth_uv + 7)&~7;

	nMbWidth_uv = (nWidth_uv * 2 + 31)&~31;
	nMbWidth_uv >>= 5;// / 32

	nMbHeight_uv = (nHeight_uv + 31)&~31;
	nMbHeight_uv >>= 5;// / 32
	ptr_uv = pSrc_v;
	pDstU = pDst + (nWidth * nHeight) + (nWidth / 2 * nHeight / 2);
	pDstV = pDst + (nWidth * nHeight);
	nWidthMatchFlag_uv = 0;
	nCopyMbWidth_uv = nMbWidth_uv - 1;

	if ((nMbWidth << 5) == nLineStride)// * 32
	{
		nWidthMatchFlag = 1;
		nCopyMbWidth = nMbWidth;
	}

	if ((nMbWidth_uv << 4) == nLineStride_uv)//*16
	{
		nWidthMatchFlag_uv = 1;
		nCopyMbWidth_uv = nMbWidth_uv;

	}

	for (i = 0; i < nMbHeight; i++)
	{
		for (j = 0; j < nCopyMbWidth; j++)
		{
			for (m = 0; m < 32; m++)
			{
				if (((i << 5) + m) >= nHeight)// * 32
				{
					ptr += 32;
					continue;
				}
				srcAsm = ptr;
				lineNum = (i << 5) + m;           //line num      * 32
				offset = lineNum * nLineStride + (j << 5);// * 32
				dstAsm = pDst + offset;

				memcpy(dstAsm, srcAsm, 32);

				if (bCnt2)
				{
					srcAsm_uv = ptr_uv;
					lineNum_uv = (i << 4) + m;           //line num i / 2 * 32
					offset_uv = lineNum_uv * nLineStride_uv + (j << 4);// * 16
					dst0Asm = pDstU + offset_uv;
					dst1Asm = pDstV + offset_uv;

					memcpy(dst0Asm, srcAsm_uv, 16);
					memcpy(dst1Asm, (void *)(srcAsm_uv + 16), 16);
					ptr_uv += 32;
				}
				ptr += 32;
			}
		}

		if (nWidthMatchFlag != 1)
		{
			for (m = 0; m < 32; m++)
			{
				if (((i << 5) + m) >= nHeight)// * 32
				{
					ptr += 32;
					continue;
				}
				dstAsm = bufferY;
				srcAsm = ptr;
				lineNum = (i << 5) + m;           //line num   * 32
				offset = lineNum * nLineStride + (j << 5);// * 32

				memcpy(dstAsm, srcAsm, 32);
				ptr += 32;
				for (k = 0; k < 32; k++)
				{
					if ((j * 32 + k) >= nLineStride)
					{
						break;
					}
					pDst[offset + k] = bufferY[k];
				}
			}
		}

		if (bCnt2) {
			if (nWidthMatchFlag_uv != 1)
			{
				for (m = 0; m < 32; m++)
				{
					if (((i << 4) + m) >= nHeight_uv)//i / 2 * 32
					{
						ptr_uv += 32;
						continue;
					}

					srcAsm = ptr_uv;
					lineNum_uv = (i << 4) + m;           //line num i / 2 * 32
					offset = lineNum_uv * nLineStride_uv + (j << 4);// * 16
					dst0Asm = bufferU;
					dst1Asm = bufferV;

					memcpy(dst0Asm, srcAsm, 16);
					memcpy(dst1Asm, (char *)(srcAsm + 16), 16);
					ptr_uv += 32;

					for (k = 0; k < 16; k++)
					{
						if (((j << 4) + k) >= nLineStride_uv)// j * 16
						{
							break;
						}
						pDstV[offset + k] = bufferV[k];
						pDstU[offset + k] = bufferU[k];
					}
				}
			}
		}
		bCnt2 = !bCnt2;
	}
}

在函数ConvertPixelFormat的
if(pPictureOut->ePixelFormat==PIXEL_FORMAT_YV12){
和#ifdef CEDARX_DECODER_ARM32之间添加以下内容

if(pPictureIn->ePixelFormat == PIXEL_FORMAT_YUV_MB32_420)
{
    MB32_CVT_YV12(pPictureIn->pData0, pPictureIn->pData1, pPictureOut->pData0, \
                    pPictureIn->nWidth, pPictureIn->nHeight);
}

清除libcedarc之前的编译文件

make clean

清除buildroot对于libcedarc的编译标记

rm .stamp_built

3.和v3s一样给gstreamer的openmax插件添加全志的颜色空间定义

cd ../gst-omx-1.16.0/

vim omx/gstomxvideo.c

在函数gst_omx_video_get_format_from_omx的switch下添加case

case OMX_COLOR_FormatYVU420Planar:
format = GST_VIDEO_FORMAT_YV12;
break;

保存退出

清除gst-omx之前的编译文件
(之前那篇帖子有人说OMX_COLOR_FormatYVU420Planar找不到定义我估计就是这个没有清)

make clean

清除buildroot对于gst-omx的编译标记

rm .stamp_built

回到buildroot目录

cd ../../../

编译

make

这样源文件的修改就完成了 gstreamer的配置就看回上面v3s的主题
打包烧录后进入系统进行gst-omx注册后就可以进行硬解码播放了

我说我杀人不眨眼你问我眼睛酸不酸？
上面搞了这么多都是硬解视频流声音要先把声卡配出来然后用以下命令解码才有

gst-launch-1.0 filesrc location=bad_apple.mp4 ! qtdemux name=demux demux.audio_0 \
! queue ! decodebin ! audioconvert ! audioresample ! alsasink \
demux.video_0 ! queue ! h264parse ! omxh264dec ! videoconvert ! videoscale ! fbdevsink

我知道了，R3默认的是串口1，不是串口0

昨天调了一天，按照教程 /dev中始终不出现cedar_dev和ion 这两个

内核中也勾选cedarx,编译后放进TF卡启动，就是不出现

大神，帮我看看，是哪一步出错了。。

感谢楼主，楼主上面中 MB32_CVT_YV12_是不是多了_符号。

从后面输出的显示来看应该是一直在解码的样子。这里fb显示报的警告说大量缓冲区的数据被丢弃了。

18楼的问题已修复修复了两个问题
1.字节对齐问题
就是https://whycan.com/t_6139.html里说的 “并且分辨率: 32的整数倍* 32的整数倍偏离一个像素都可能导致错误。”
现在分辨率不是32整数倍的视频也可以正常播放了
2.颜色错误问题
测试其他视频发现颜色不对现已修复

测试镜像：
F1C200s主线gstreamer使用openmax调用cedar硬解码附件20210813.zip
下楼改源文件修复问题

在buildroot进入目录output/build/libcedarc-master

cd output/build/libcedarc-master

修改源文件omx_vdec_aw_decoder_linux.c

vim openmax/vdec/src/omx_vdec_aw_decoder_linux.c

在结构体类型typedef struct OmxAwDecoderContext增加以下成员

int                    tWidth;
int                    tHeight;

在
#if (ENABLE_SCALEDOWN_WHEN_RESOLUTION_MOER_THAN_1080P)
if (pCtx->mStreamInfo.nWidth > 1920
&& pCtx->mStreamInfo.nHeight > 1088)
{
pCtx->mVideoConfig.bScaleDownEn = 1;
pCtx->mVideoConfig.nHorizonScaleDownRatio = 1;
pCtx->mVideoConfig.nVerticalScaleDownRatio = 1;
}
#endif
下面添加

        pCtx->tWidth = pCtx->mStreamInfo.nWidth;
        pCtx->tHeight = pCtx->mStreamInfo.nHeight;
        pCtx->mStreamInfo.nWidth = (pCtx->mStreamInfo.nWidth + 31) & ~31;
        pCtx->mStreamInfo.nHeight = (pCtx->mStreamInfo.nHeight + 31) & ~31;

在函数
static int __liCallback(OmxDecoder* pDec, DecoderCallback callback,
void* pUserData)
上面添加一个函数

static int yv12_align_fill(char* p_dst, int w, int h, int aw, int ah)
{
	int i, j;
	int map = aw * ah;
	int v_size = (map) >> 2;
	char *pv = p_dst + map;
	char *pu = pv + v_size;//  / 4

	int dw = aw - w;
	int dh = ah -h;
	int dw_h = dw / 2;
	int dh_h = dh / 2;
	int w_h = w / 2;
	int h_h = h / 2;
	int aw_h = aw / 2;
	int ah_h = ah / 2;
	int map_oft = aw_h * h_h;
	
	if((w == aw) && (h == ah))
		return 0;


	for(i=0;i<h_h;i++)
	{
		for(j=0;j<dw_h;j++)
		{
			pv[w_h + j + aw_h * i] = 128;
			pu[w_h + j + aw_h * i] = 128;
		}

	}
	

	for(i=0;i<dh_h;i++)
	{
		for(j=0;j<aw_h;j++)
		{
			pv[map_oft + j + aw_h * i] = 128;
			pu[map_oft + j + aw_h * i] = 128;
		}
		
	}

	return 0;
}

在函数__liDrain中
RotatePicture(pCtx->decMemOps, pCtx->pPicture, &pCtx->CvtPicture, 0, 32, 32);
的下面添加

yv12_align_fill(pCtx->CvtPicture.pData0, pCtx-> tWidth, pCtx-> tWidth, pCtx->mStreamInfo.nWidth, pCtx->mStreamInfo.nHeight);

保存退出

修改源文件pixel_format.c

vim vdecoder/pixel_format.c

把函数
MB32_CVT_YV12
替换成

保存退出

清除libcedarc之前的编译文件

make clean

清除buildroot对于libcedarc的编译标记

rm .stamp_built

回到buildroot目录

cd ../../../

编译

make

这样源文件的修改就完成了

修改了源码重新编译下载，并替换了注册文件注后，还是无法使用，能帮我看下吗？

请问 Caught SIGSEGV 问题解决了吗？我按照楼主的方法更改了代码，重新编译后还会出现同样的问题

贴子要沉了吗？手动顶一下，我用ffmpeg改了编码方式和分辨率，这个段错误就消失了
现在图片不居中显示，还没解决，开始看源码尝试解决。

请问楼主 ERROR : omx_vdec <AwOmxVdecPortGetFormat:290>: erro: pParamData->nIndex > m_sPortFormatType.nIndex
出现这个的原因是什么 ? 是颜色空间没加吗？

请问 Caught SIGSEGV 问题解决了吗？我按照楼主的方法更改了代码，重新编译后还会出现同样的问题

wj8331585 · 2023-06-11 09:59:38

mpeg4解码用上面的方法，好像播放不了avi视频

hle999 · 2023-10-24 16:52:31

可以播放mp4，CPU加了超频，但也很卡，感觉还没有在lvgl上的ffmpeg软解快，底部也有泛绿。DE还没看懂怎么加

Iric · 2023-12-31 16:26:53

我报的错误和其他人都不一样，这也没有错误信息，可能是什么问题呢？

发现播放其他mp4就直接出现 Caught SIGSEGV 了，看来还是有些问题，但也超出我的水平范围了.
