Hi, I've pulled the latest git ffmpeg and schroedinger and hacked/configured ffmpeg's libschroedinger_encode_init to use SCHRO_ENCODER_RATE_CONTROL_LOW_DELAY. I processed a sequence of 1920x1080 HD RGB24 frames one at a time as YUV422 (YUV444 coredumps) and see flickering diagonal bands of noise moving over the frames.
I then did roughly the same experiment with git dirac-research -- no low delay processing(?), and YUV444, which is what I actually want -- and the noise bands are not there for the same compression ratio. schroedinger: http://stacey-campbell.com/test-230M.mp4 dirac-research: http://stacey-campbell.com/test-107M.mp4 The compression ratio is roughly 5:1 for both. The clips were converted PPM->DRC->PPM (for per-frame PSNR calc)->MP4 (200Mbit). The diagonal noise bands are in the schroedinger clips regardless of compression ratio. My platform is Cygwin on Win 7 x64, schroedinger has threads disabled (pthreads coredumps).
