Stephen Neal pointed out that professional PCM was 44055hz for this reason... so my plan for fixing this is to offer a locked NTSC option for that (735 samples/field) and...
Fixing this should take care of the Blackadder issues raised in #252
Added a sample from the Swedish Karaoke disk that dramatically slows down and fails to decode.
Yup. My personal philosophy is when it's in RGB and pcm, it's out of ld-decode's domain - ffmpeg can crop overscan, and it may vary according to the content.
N5105 notes: Not nearly as slow as I expected. Looks like ~1fps on ld-decode, and most of the slowness in OpenCL is data transfer, so the GPU results are even...
I played around with doing int16->complex64 conversion on the GPU side, and it's now 50x faster at 1MB buffers and ~2x with 32K buffers on my main system, if I'm...
I OpenCL'ified the RF stage, but performance gains are slight now because of pyopencl not releasing the GIL much, on top of switching to the threading model. https://github.com/happycube/ld-decode/tree/chad-2023.06.11-opencl2 I hear...
I converted the filters and FFT processing to float32/complex64 (which should convert much of the TBC code further down the line), and performance is 15% higher on my AVX1 Sandy...
It's regressed and now vrooping
oopsie. backed out unintentional commit.
