| Ticket Name: RTOS/TDA2: how to save encoded h.264 data and play on pc ?? | |
| Query Text: | |
| Part Number: TDA2 Tool/software: TI-RTOS my platform is tda2pxx , I had run the usecase "capture > encode > decode > diplay" now I want to record some frames video. so i write the usecase "capture > encode > null_save" , in null_save callback . i save the h.264 data to file . but i can't play it on pc using elecard streameye . the file code.txt is the callback func, i write , is there some wrong ?IDR.txt 0042.code.txt UInt32 idrCnt=0; | |

| } the file IDR.txt is idr h264 data, can you help me to check if the data is right ? i checked many frames , the start code of each frame is 00 00 00 01 , there is no other nalu type, why? | |

| Hi This file dump and playing with VLC media player is already validated For the Null link file write set below configuration. pUcObj->NullPrm.dumpDataType = NULL_LINK_COPY_TYPE_FILE; strcpy(pUcObj->NullPrm.nameDataFile[0], "stream.h264"); I assume you use VSDK 3.3 release regards, Shiju | |
