Hi,
I am able to compress Input PAL video from ADV7182 in ADV212. (If I removed the ADV212 header and extract frames the frames are fine when viewed using kdu image viewer).
I am facing problem in decompressing the video. At decompression end I am using ADV7391 for converting pixel data from ADV212 to analog video.
I am using 32bit normal host mode.
My compression parameters are,
VFORMAT = 0x01
PREC = 0x00
XFORMLEV = 0x05
UNI = 0x03
CBSIZE = 0x00
WKERNEL = 0x00
STALLPAR = 0x00
ATTRTYPE = 0x00
RCTYPE = 0x01
RCVAL = 0x002710
J2KPROG = 0x00
PICFG = 0x01
QFACT = 0x00
COD_STYLE = 0x01
PLL_HI = 0x08
PLL_LO = 0x04
Decompression parameters,
VFORMAT = 0x01
PREC = 0x00
UNI = 0x03
PICFG = 0x11
QFACT = 0x00
COD_STYLE = 0x01
MCLK and VCLK = 27MHz.
Note:
1) I have attached a snapshot of compressed video(viewed in kdu viewer), and decompressed video played using monitor.
2) The I2c registers I am writing for ADV7391 are
0x54 0x17
0x54 0x00
0x54 0x01
0x54 0x80
0x54 0x82
0x54 0x8C
0x54 0x8D
0x54 0x8E
0x54 0x8F
3) I am just polling EIRQFLG bit 1 for writing data to CODEFIFO.
Can anyone tell where am I going wrong, Its bit urgent. Expecting reply ASAP.
