TI中文支持网hi,
参照Multich_tristream_fullfeature.c 从camerLink里获得张yuv420sp，chId=2是已设置成JPG编码格式，其他通道chId=0或chId=1,如何更改参数使该幅图像编码成jpg图像，请TI方面的高手帮忙解决…
Ternence_Hsu：
你好；
你在Multich_tristream_fullfeature.c 修改 VENC_PRIMARY_CHANNELS 的值为 0 就可以了；
这样3路编码全部都会是按照 jpeg 进行编码的

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 existsln: /etc/localtime: File existsApproDrvInit: 7queue id:131076TimeOut 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)?

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;

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_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。

回复 Chris Meng:
是在原文件基础上修改，出现的故障现象

回复 lu xinjian:
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

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？
