Hi everybody, i have interface a CMOS Raw Bayer sensor with a DVEVM. I'm able to store correctly datas send by sensor in RAM with CCDC.
But now i want to use previewer to convert Raw bayer vidéo in YUV 4:2:2 in order to obtain a video flow working on an encode demos-like application. To do this, i used sources and documents for LSP 1.20 DaVinci Linux previewer driver. And i am experiencing 2 problems. First, outbuf is strange. Of course, it has the good size but it seems to be overlap by other datas ( executable if we read those datas with hexedit ). A solution consists in not allocate buffer with previewer driver but use a buffer created by another module ( like codec engine ... ) Then, the previewer driver crash after encoding a random number fo frames ( generally about 25-30 ). His busy flag is always 1 and never goes down ... Do you already used previewer driver correctly ? And do you already have some datas overlapping or crash problems ? Regards. Pierre Emmanuel
