- oakcodec: de-Qt all 20 sources (QThread decode loop -> std::thread,
QObject/signals -> callbacks), pure C ABI in include/codec with
refcounted neutral handles (OakFrame/OakDecoder/OakEncoder),
framemanager moved in from render, frame_to_buffer/buffer_to_frame
moved in from oakcommon oiioutils, codec->task via submit callback
(M8 will register), all cross-module calls go through the other
side's C API, -fvisibility=hidden + OAKCODEC_API
- oakcommon: handles become refcounted value structs
{ctx, addref, release, abi_version} (FFmpeg-style), pass-by-value
signatures, free() as release wrapper; init_from_native/get_native
for copyable value objects; OakCommonXxx renamed to OakXxx
- oakcommon: add logging (log_debug/info/warning/critical with level
filtering and sink injection) + printf-style oakcommon_log C wrapper
- oakrender: add CancelAtom C API family; complete
oakrender_color_processor_convert_frame; fix get_processor() missing
definition and OCIO env var lookup
- tests: oakcommon 174, oaknode 96, oakrender 42, oakcodec 18, all
green in their standalone builds

/**
|
|
* @brief Neutral handle convention shared by all oakcommon wrappers.
|
|
*
|
|
* Every wrapper type is a by-value struct with the same four fields:
|
|
*
|
|
* typedef struct OakXxx {
|
|
* void *ctx; // opaque, points to the impl
|
|
* void (*addref)(void *ctx); // atomic +1, owner-DLL code
|
|
* void (*release)(void *ctx); // atomic -1, destroys at 0
|
|
* uint32_t abi_version; // OAKCOMMON_ABI_VERSION
|
|
* } OakXxx;
|
|
*
|
|
* Rules:
|
|
* - oakcommon_<name>_init*() returns a handle whose underlying object
|
|
* has reference count 1.
|
|
* - Copying the struct copies the pointer, not the count: call
|
|
* handle.addref(handle.ctx) for every additional long-lived copy and
|
|
* handle.release(handle.ctx) (or the oakcommon_<name>_free()
|
|
* convenience wrapper) when done with each copy.
|
|
* - release() decrements the atomic count and destroys the underlying
|
|
* object when it reaches zero; the destructor runs in the DLL that
|
|
* created the object, so cross-DLL handing is safe.
|
|
* - The struct itself carries no ownership: it is never heap-allocated
|
|
* by the API, so it needs no destruction of its own.
|
|
* - Functions that only read a handle take it BY VALUE (OakXxx self);
|
|
* an empty handle (ctx == NULL) is reported as OAKCOMMON_E_INVALID.
|
|
* oakcommon_<name>_free() deliberately stays a pointer API
|
|
* (OakXxx *h, like av_frame_unref()/av_buffer_unref()) so it can
|
|
* null out the caller's ctx after the final release; NULL and
|
|
* ctx == NULL are no-ops. Out parameters that produce a handle
|
|
* (e.g. option/positional-argument registration) also stay pointers.
