TI中文支持网在采集–编码–显示demo里，采集四路视频，0~3采集通道依次是pal、pal、sdi和vga；
发现问题：前三路没有编码数据，只有第四路vga有编码数据可存成h264文件，前3路文件大小一直为0，四路显示均正常。
排除过程：一度怀疑VcapVenc_bitsWriteCreate()—>status = OSA_thrCreate(&gVcapVenc_ctrl.wrThrHndl,VcapVenc_bitsWriteMain,OSA_THR_PRI_DEFAULT,0,&gVcapVenc_ctrl)中的条件变量等待，但是
MultiCh_ipcBitsInitCreateParams_BitsInHLOS(&ipcBitsInHostPrm);
System_linkCreate(gVencModuleContext.ipcBitsInHLOSId, &ipcBitsInHostPrm, sizeof(ipcBitsInHostPrm));
编码部分一直发信号量，不存在阻塞的。即是去掉VcapVenc_bitsWriteMain（）中的等待条件变量一样没编码数据。
首先为了缩小问题范围，将采集改成只有pal一路视频，也就是一个采集实例，发现实际的阻塞是因为VcapVenc_bitsWriteMain(void *pPrm)–>status = Venc_getBitstreamBuffer(&bitsBuf, TIMEOUT_NO_WAIT)，bitsBuf.numBufs= 0，也就是根本没有编码数据，至少是存编码文件这个线程中没有数据，即进去跟踪
IpcBitsInLink_getFullVideoBitStreamBufs(gVencModuleContext.ipcBitsInHLOSId,&ipcBufList)，ipcBufList.numBufs = 0，再进去发现status = IpcBitsInLink_getFullBitBufs(pObj,bufList)，bufList->numBufs = 0, 进去又发现
OSA_queGet(&pObj->outBitBufQue,(Int32 *) (&pBitBufList->bufs[idx]), OSA_TIMEOUT_NONE)，hndl->count只有前3次不为0，后面一直为0。
问题在哪里，难道真是没有编码吗？通过上面的跟踪打印也只能看出事A8核确实没有编码数据，那么在M3Video核到底有没有产生数据呢，因为video核的都是link，没法打印调试具体有没有数据。因为同样的软件，有两个pal、一个sdi和第四路是vga时，vga可保存编码数据，可以说原来的软件流程是没问题，那么这个问题怎么调试可看出M3核到底有没有编码呢
Ternence_Hsu：
你好；你能确定你 4路码流 都采集到了吗？
Ternence_Hsu：
你有没有到 m3 里面去 debug 数据
user4748636：
回复 Ternence_Hsu:
四路采集到了，通过display可以在显示其上看到思路画面
第四路是vga，也可以存成文件。
为了测试方便，只保留了第一路pal采集其他几路实例去掉了，偶然间pal存了十几秒，但是回放是画面异常画

回复 Ternence_Hsu:
首先将M3video改为debug，rule.make改为
# Default profileifeq ($(PROFILE_m3video), )# PROFILE_m3video := release# PROFILE_m3video := debug PROFILE_m3video := debugendif
编译后运行了，视频是一路pal（720*576），视频画面预览正常，可是没有m3video debug方面的打印，和release版的打印一样啊，怎么debug打印调试呢？

问题：
1.将m3video改成debug板，没有出现video方面的打印，如何出现相m3video的信息?
2.改m3video debug的时候，因为出现编译错误，将
//var ETH_OFFLOAD_SIZE = 64*KB;
var ETH_OFFLOAD_SIZE = 40*KB;
出现了上面的打印，也就是编码器编码了很多数据，但是相比正常的编码数据少了很多，存文件也很小，很长时间也只有128k，这128k的视频用暴风影音可以断断续续的看到实际画面，也就是说，现在还不能对每帧数据进行编码，为啥

回复 user4748636:
你好，
Rules.make里面修改的debug是编译选项的修改，就是不优化。
如果你想打印更多的debug信息，请参考system_debug.h。

回复 Chris Meng:
好的，看到debug信息了
