[FFmpeg-devel] [PATCH] fate/jpeg2000dec: add selected conformance codestreams from ISO/IEC 15444-4

[WATANABE Osamu]

Hi Pierre, Tomas,

For lossy codestreams, I found a potential problem on the current 9x7 integer IDWT (which will be activated with the +bitexact flag.)

I have confirmed that FFMPEG passes all the test cases without the flag.

The problem has been locally solved with the updated code, however, the patch set is not yet ready.
(It won't take long)

Best,
Osamu
