Hi All,
I have downloaded the evaluation versions of codec from TI's website. I
was working on making the decode application with the decodecombo
created with this eval version of codecs.
What i have seen in the description written on the top of It's
application's c source file is, it will use 8MB CMEM for encoded input
file length of 2MB, and i have to increase the length of CMEM if i want
to decode the file whose size is more than 2MB.
Version of codec combo package is as below:
dm6446_dvsdk_combos_1_35_evaluation
My problem is like when i decode only 30 frames TI's decode application
works fine and write the decoded data in to the file. But if i increase
the no. of frames from 30 to 60 it starts giving me the dump shown below:
Unable to handle kernel NULL pointer dereference at virtual address 00000000
pgd = c0004000
[00000000] *pgd=00000000

So I just want to confirm that is it a problem with application or it is
due to the evaluation versions of codec.
And if it is the problem with application then how to solve it. As what
i have observed that if i comment out the fwrite after the decoding of a
frame, the same application works perfectly for more no. of frames.
