DM8127 encLink 只编码一路JPEG如何配置参数?

 修改了Multich_tristream_fullfeature.c 里的 VENC_PRIMARY_CHANNELS 的值为 0，有两处

1，

MULTICH_INIT_STRUCT(EncLink_CreateParams, encPrm);
{
EncLink_ChCreateParams *pLinkChPrm;
EncLink_ChDynamicParams *pLinkDynPrm;
VENC_CHN_DYNAMIC_PARAM_S *pDynPrm;
VENC_CHN_PARAMS_S *pChPrm;

//for (i = 0; i < VENC_PRIMARY_CHANNELS; i++)//这一处修改为

for (i = 0; i < 0; i++)/

2，

//for (i = VENC_PRIMARY_CHANNELS; i < (VENC_CHN_MAX - 1); i++) //修改为

for (i = 0; i < 0; i++)

编译后运行出现这种故障

ln: /etc/localtime: File exists
ln: /etc/localtime: File exists
ApproDrvInit: 7
queue id:131076
TimeOut occure in boot_proc.
Program exit.
TimeOut occure in boot_proc.
Program exit

另一种在ti_venc.h里修改

#define VENC_PRIMARY_CHANNELS   (0)//(2)

编译后也出现上面结果

请问具体什么修改？

你好，

你能否尝试修改下面的编码格式都为JPEG？

    /* Video Encoder Link params */
    MULTICH_INIT_STRUCT(EncLink_CreateParams, encPrm);
    {
        EncLink_ChCreateParams *pLinkChPrm;
        EncLink_ChDynamicParams *pLinkDynPrm;
        VENC_CHN_DYNAMIC_PARAM_S *pDynPrm;
        VENC_CHN_PARAMS_S *pChPrm;

        for (i = 0; i < VENC_PRIMARY_CHANNELS; i++)
        {
            pLinkChPrm  = &encPrm.chCreateParams[i];
            pLinkDynPrm = &pLinkChPrm->defaultDynamicParams;

            pChPrm      = &gVencModuleContext.vencConfig.encChannelParams[i];
            pDynPrm     = &pChPrm->dynamicParam;

            switch(gUI_mcfw_config.demoCfg.codec_combo) {
                case 0: pLinkChPrm->format = IVIDEO_H264HP; break; //"SINGLE_H264"
                case 1: pLinkChPrm->format = IVIDEO_MPEG4SP; break; //"SINGLE_MPEG4"
                case 2: pLinkChPrm->format = IVIDEO_MJPEG; break; //"SINGLE_JPEG"
                case 3: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_MJPEG; break; //"H264_JPEG"
                case 4: pLinkChPrm->format = (i==0)? IVIDEO_MPEG4SP:IVIDEO_MJPEG; break; //"MPEG4_JPEG"
                case 5: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_H264HP; break; //"DUAL_H264"
                case 6: pLinkChPrm->format = (i==0)? IVIDEO_MPEG4SP:IVIDEO_MPEG4SP; break; //"DUAL_MPEG4"
                case 7: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_MPEG4SP; break;  //"H264_MPEG4"
                case 8: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_H264HP; break;  //"TRIPLE_H264"
                case 9: pLinkChPrm->format = (i==0)? IVIDEO_MPEG4SP:IVIDEO_MPEG4SP; break; //"TRIPLE_MPEG4"
                default: pLinkChPrm->format = IVIDEO_H264HP;
            }

hi,你好

修改一处

MULTICH_INIT_STRUCT(EncLink_CreateParams, encPrm);
{
EncLink_ChCreateParams *pLinkChPrm;
EncLink_ChDynamicParams *pLinkDynPrm;
VENC_CHN_DYNAMIC_PARAM_S *pDynPrm;
VENC_CHN_PARAMS_S *pChPrm;

for (i = 0; i < VENC_PRIMARY_CHANNELS; i++)//i < VENC_PRIMARY_CHANNELS
{
pLinkChPrm = &encPrm.chCreateParams[i];
pLinkDynPrm = &pLinkChPrm->defaultDynamicParams;

pChPrm = &gVencModuleContext.vencConfig.encChannelParams[i];
pDynPrm = &pChPrm->dynamicParam;
gUI_mcfw_config.demoCfg.codec_combo = 2;//修改了一处
switch(gUI_mcfw_config.demoCfg.codec_combo) {
case 0: pLinkChPrm->format = IVIDEO_H264HP; break; //"SINGLE_H264"
case 1: pLinkChPrm->format = IVIDEO_MPEG4SP; break; //"SINGLE_MPEG4"
case 2: pLinkChPrm->format = IVIDEO_MJPEG; break; //"SINGLE_JPEG"
case 3: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_MJPEG; break; //"H264_JPEG"
case 4: pLinkChPrm->format = (i==0)? IVIDEO_MPEG4SP:IVIDEO_MJPEG; break; //"MPEG4_JPEG"
case 5: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_H264HP; break; //"DUAL_H264"
case 6: pLinkChPrm->format = (i==0)? IVIDEO_MPEG4SP:IVIDEO_MPEG4SP; break; //"DUAL_MPEG4"
case 7: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_MPEG4SP; break; //"H264_MPEG4"
case 8: pLinkChPrm->format = (i==0)? IVIDEO_H264HP:IVIDEO_H264HP; break; //"TRIPLE_H264"
case 9: pLinkChPrm->format = (i==0)? IVIDEO_MPEG4SP:IVIDEO_MPEG4SP; break; //"TRIPLE_MPEG4"
default: pLinkChPrm->format = IVIDEO_H264HP;
}

编译后还会出现这种故障现象，可能是还有其他的地方没有更改好

你好，

请问你是否保留了对VENC_PRIMARY_CHANNELS的修改？如果是，能否还原VENC_PRIMARY_CHANNELS的值，然后看看。

是在原文件基础上修改，出现的故障现象

保留了

for (i = 0; i < VENC_PRIMARY_CHANNELS; i++)//的VENC_PRIMARY_CHANNELS不变

更改 

//for (i = VENC_PRIMARY_CHANNELS; i < (VENC_CHN_MAX - 1); i++)为

for (i = 0; i < (VENC_CHN_MAX - 1); i++)

也会上面出现的故障

另外一种方式把全局VENC_PRIMARY_CHANNELS更改定义为0也同样出现上面故障现象

按道理说是可以的，是否有初始化变量没同步改？

如果按appro里面设置为单jpg输出格式，有没有作如下更改

for (i = 0; i < VENC_PRIMARY_CHANNELS; i++)//i < VENC_PRIMARY_CHANNELS
{
pLinkChPrm = &encPrm.chCreateParams[i];
pLinkDynPrm = &pLinkChPrm->defaultDynamicParams;

pChPrm = &gVencModuleContext.vencConfig.encChannelParams[i];
pDynPrm = &pChPrm->dynamicParam;
gUI_mcfw_config.demoCfg.codec_combo = 2;//修改了一处
switch(gUI_mcfw_config.demoCfg.codec_combo) {

编译都不影响，用VLC能看到MJPEG流

运行提示发出的流如下

Initializing...
...done initializing

rtsp://192.168.1.168:8555/PSIA/Streaming/channels/0?videoCodecType=MJPEG

其中

rtsp://192.168.1.168:8553/PSIA/Streaming/channels/1?videoCodecType=MPEG4

rtsp://192.168.1.168:8556/PSIA/Streaming/channels/2?videoCodecType=H.264

这两个流用VLC是不能显示异常

用ps命令查看后台的进程仍有3个

601 root 67000 S ./wis-streamer -s
602 root 90444 R ./wis-streamer -s
603 root 67000 S ./wis-streamer -s

请问开机软件如何设置为单一的jpeg或多个都为jpg参数设置？而wis-streamer -s是在哪里开启相应的进程？
