Hi TI experts,
My problem is when I run h263dec(mpeg4) decoding 4CIF resolution on DM6467, the programm return error as follow,
@6,254,097us: [+2 T:0x4001ee40 S:0xbea5d03c] ti.sdo.dmai - [Vdec2] VIDDEC2_process() ret -1 inId 0 inUse 0 consumed 4
@6,254,196us: [+2 T:0x4001ee40 S:0xbea5d03c] ti.sdo.dmai - [Vdec2] VIDDEC2_process() non-fatal error 0x0
The other three small resolutions SQCIF\QCIF\CIF can be processed normal. I find the decoder userguide document where write
DM6467_ERR_STREAM
Bit 2-4 (Range – 0 to 7)
ERR_NONE = 0
Stream error.
ERR_SOF = 1
Error in the start of frame
which renders the entire
frame undecodable.
ERR_HDR = 2
Parts of the frame are not
decodable due to header
loss but other parts are
decodable completely.
ERR_HDR_MBDATA = 3
In addition to header loss,
bitstream errors prevent
some MBs from being
decoded correctly.
ERR_MBDATA = 4
Header data is intact but
bitstream errors prevent
some MBs from being
decoded correctly.
ERR_CONTENT = 5
Bitstream contains
unsupported content but
decoding can proceed.
ERR_CRITICAL = 6
Bitstream contains errors
that cannot be resolved
and that a re-initialization is
required.
ERR_RESERVED = 7
Not used
I donn't confirm wether I understand correct or not.
So, I hopefully TI exports can give me some explain about this error and the solving method.
And additionally, I cann't loopback encoder and decoder on DM6467. when I create the encoder and decoder simultaneously, then I run the decoder only, the decoder runs normally. But then I run the encoder only, the encoder hangs.
I find the datasheet document write like this ,
Resource requirement:
The entire HDVICP (0/1) is a video resource and uses 16K ITCM and 8K DTCM.
18 EDMA channels and 64 additional param entries are required.
TC-3 is used for transferring data from DDR to L2
I donn't confirm wether the loopback error related with the condition "TC-3 is used for transferring data from DDR to L2". And I donn't known how to config this require.
So, hopefully TI experts can give me some suggest about this problem also.
Hopefully for your answers. Thank you.

LL
