		const NvSciSyncFence *	prenvscisyncfence
	)

Sets an NvSciSyncFence as a prefence for an NvMediaIJPDRender() NvSciSyncFence operation.

You must call NvMediaIJPDInsertPreNvSciSyncFence() before you call NvMediaIJPDRender(). The NvMediaIJPDRender() operation is started only after the expiry of the prenvscisyncfence.

For example, in this sequence of code:

nvmstatus = NvMediaIJPDInsertPreNvSciSyncFence(handle, prenvscisyncfence);

nvmstatus = NvMediaIJPDRender(handle, arg2, arg3, ...);

the NvMediaIJPDRender() operation is assured to start only after the expiry of prenvscisyncfence.

You can set a maximum of NVMEDIA_IJPD_MAX_PRENVSCISYNCFENCES prefences by calling NvMediaIJPDInsertPreNvSciSyncFence() before NvMediaIJPDRender(). After the call to NvMediaIJPDRender(), all NvSciSyncFences previously inserted by NvMediaIJPDInsertPreNvSciSyncFence() are removed, and they are not reused for the subsequent NvMediaIJPDRender() calls.

Precondition: Pre-NvSciSync fence obtained from previous engine in the pipeline

Postcondition: Pre-NvSciSync fence is set

Usage considerations

Allowed context for the API call
- Interrupt handler: No

NVMEDIA_STATUS_NOT_SUPPORTED if NvMediaIJPDInsertPreNvSciSyncFence() has already been called at least NVMEDIA_IJPD_MAX_PRENVSCISYNCFENCES times with the same decoder handle before an NvMediaIJPDRender() call.

◆ NvMediaIJPDRegisterNvSciBufObj()

NvMediaStatus NvMediaIJPDRegisterNvSciBufObj	(	const NvMediaIJPD *	decoder,
		NvSciBufObj	bufObj
	)

Registers NvSciBufObj for use with a NvMediaIJPD handle.

NvMediaIJPD handle maintains a record of all the objects registered using this API and only the registered NvSciBufObj handles are accepted when submitted for decoding via NvMediaIJPDRender. Even duplicated NvSciBufObj objects need to be registered using this API prior.

This needs to be used in tandem with NvMediaIJPDUnregisterNvSciBufObj(). The pair of APIs for registering and unregistering NvSciBufObj are optional, but it is highly recommended to use them as they ensure deterministic execution of NvMediaIJPDRender().

To ensure deterministic execution time of NvMediaIJPDRender API:

NvMediaIJPDRegisterNvSciBufObj must be called for every input NvSciBufObj that will be used with NvMediaIJPD
All NvMediaIJPDRegisterNvSciBufObj calls must be made before first NvMediaIJPDRender API call.

Registration of the buffer (output) is always with read-write permissions.

Maximum of 32 NvSciBufObj handles can be registered.

Note: This API is currently not supported and can be ignored

Precondition: NvMediaIJPDCreate(); NvMediaIJPDRegisterNvSciSyncObj()

Postcondition: NvSciBufObj is registered with NvMediaIJPD object

Usage considerations

Allowed context for the API call
- Interrupt handler: No
- Signal handler: No
- Thread-safe: Yes, with the following conditions
  - Every thread should be invoked with relevant NvMediaIJPD object.
- Re-entrant: No

Required privileges: None
API group
- Init: Yes
- Runtime: No
- De-Init: No

Parameters

[in]	decoder	A pointer to the NvMediaIJPD object. Input range: Non-NULL - valid pointer address
[in]	bufObj	NvSciBufObj object Input range: A valid NvSciBufObj

Returns

NvMediaStatus, the completion status of operation:

NVMEDIA_STATUS_NOT_SUPPORTED if API is not functionally supported

◆ NvMediaIJPDRegisterNvSciSyncObj()

NvMediaStatus NvMediaIJPDRegisterNvSciSyncObj	(	const NvMediaIJPD *	decoder,
		NvMediaNvSciSyncObjType	syncobjtype,
		NvSciSyncObj	nvscisync
	)

Registers an NvSciSyncObj with NvMediaIJPD.

Every NvSciSyncObj (even duplicate objects) used by NvMediaIJPD must be registered by a call to this function before it is used. Only the exact same registered NvSciSyncObj can be passed to NvMediaIJPDSetNvSciSyncObjforEOF(), NvMediaIJPDGetEOFNvSciSyncFence(), or NvMediaIJPDUnregisterNvSciSyncObj().

For a given NvMediaIJPD handle, one NvSciSyncObj can be registered as one NvMediaNvSciSyncObjType only. For each NvMediaNvSciSyncObjType, a maximum of 16 NvSciSyncObjs can be registered.

		NvMediaJPEGInstanceId	instanceId
	)

Decodes a JPEG image.

The decode pipeline produces a result equivalent to the following sequence:

Decodes the full JPEG image.
Downscales the 8x8 block padded image by the downscaleLog2 factor. That is, a "width" by "height" JPEG is downscaled to:
```
((width + 7) & ~7) >> downscaleLog2
```
by
```
((height + 7) & ~7) >> downscaleLog2
```
From the downscaled image, removes the rectangle described by srcRect and optionally (a) mirrors the image horizontally and/or vertically and/or (b) rotates the image.
Scales the transformed source rectangle to the dstRect on the output surface.

Specifying Dimensions

The JPEG decoder object must have maxWidth and maxHeight values that are greater than or equal to the post-downscale JPEG image. Additionally, it must have a maxBitstreamBytes value that is greater than or equal to the total number of bytes in the bitstream buffers. You set these values when you create the JPEG decoder object with NvMediaIJPDCreate(). Alternatively, you can user NvMediaIJPDResize() to change the dimensions of an existing JPEG decoder object.

If the JPEG decoder object has inadequate dimensions, NvMediaIJPDRender() returns NVMEDIA_STATUS_INSUFFICIENT_BUFFERING.

Supporting Partial Acceleration

If the JPEG stream requires partial acceleration, created the JPEG decoder object with supportPartialAccel set to '1'. Otherwise, the function returns NVMEDIA_STATUS_BAD_PARAMETER.

Use NvMediaIJPDGetInfo() to determine whether a stream requires paritialAccel.

Determining Supported JPEG Streams

If the JPEG stream is not supported, the function returns NVMEDIA_STATUS_NOT_SUPPORTED.

Use NvMediaIJPDGetInfo() to determine whether a stream is unsupported.

Note: NvMediaIJPDRender() with the NVJPG 1.0 codec does not support rotation.

Parameters

[in]	decoder	A pointer to the JPEG decoder to use.
[out]	target	NvSciBufObj that contains the decoded content, allocated with a call to NvSciBufObjAlloc. Supported surface format attributes: Buffer Type: NvSciBufType_Image Surface Type: RGBA Bit Depth: 8 Layout: NvSciBufImage_PitchLinearType Scan Type: NvSciBufScan_ProgressiveType Plane base address alignment: 256
[in]	srcRect	The source rectangle. The rectangle from the post-downscaled image to be transformed and scaled to the dstRect. You can achieve horizontal and/or vertical mirroring by swapping the left-right and/or top-bottom coordinates. If NULL, the full post-downscaled surface is implied.
[in]	dstRect	The destination rectangle on the output surface. If NULL, a rectangle the full size of the output surface is implied.
[in]	downscaleLog2	A value clamped between 0 and 3 inclusive, gives downscale factors of 1 to 8.
[in]	numBitstreamBuffers	The number of bitstream buffers.
[in]	bitstreams	The bitstream buffer. `NvMediaIJPDRender`() copies the data out of these buffers so the caller is free to reuse them as soon as `NvMediaIJPDRender`() returns.
[in]	flags	Flags that specify a clockwise rotation of the source in degrees and horizontal and vertical flipping. If both are specified, the image is flipped before it is rotated. You can set the flags argument to any one of the following: NVMEDIA_RENDER_FLAG_ROTATE_0 NVMEDIA_RENDER_FLAG_ROTATE_90 NVMEDIA_RENDER_FLAG_ROTATE_180 NVMEDIA_RENDER_FLAG_ROTATE_270 Additionally, you can use the bitwise OR operation to apply either or both of the following: NVMEDIA_RENDER_FLAG_FLIP_HORIZONTAL NVMEDIA_RENDER_FLAG_FLIP_VERTICAL
[in]	instanceId	The ID of the engine instance. The following instances are supported: NVMEDIA_JPEG_INSTANCE_0 NVMEDIA_JPEG_INSTANCE_1 [Supported only on T23X] NVMEDIA_JPEG_INSTANCE_AUTO [Supported only on T23X]

Returns

NvMediaStatus The completion status of the operation. Possible values are:

NVMEDIA_STATUS_OK if successful.
NVMEDIA_STATUS_BAD_PARAMETER if any of the input parameter is NULL.
NVMEDIA_STATUS_ERROR

◆ NvMediaIJPDRenderYUV()

NvMediaStatus NvMediaIJPDRenderYUV	(	const NvMediaIJPD *	decoder,
		NvSciBufObj	target,
		uint8_t	downscaleLog2,
		uint32_t	numBitstreamBuffers,
		const NvMediaBitstreamBuffer *	bitstreams,
		uint32_t	flags,
		NvMediaJPEGInstanceId	instanceId
	)

Decodes a JPEG image into YUV format.

This function is similar to NvMediaIJPDRender() except that the output surface is in YUV format, not RGBA format. Also, clipping and scaling (other than downscaleLog2 scaling) are not supported, so there are no source or destination rectangle parameters.

Note

NvMediaIJPDRenderYUV() with the NVJPG 1.0 codec has the following limitations:

It supports chroma subsample conversion to 420 and 420H from any input format except 400.
It does not simultaneously support downscaleLog2 and subsample conversion.

◆ NvMediaIJPDSetNvSciSyncObjforEOF()

NvMediaStatus NvMediaIJPDSetNvSciSyncObjforEOF	(	const NvMediaIJPD *	decoder,
		NvSciSyncObj	nvscisyncEOF
	)

Specifies the NvSciSyncObj to be used for an EOF NvSciSyncFence.

To use NvMediaIJPDGetEOFNvSciSyncFence(), the application must call NvMediaIJPDSetNvSciSyncObjforEOF() before it calls NvMediaIJPDRender().

NvMediaIJPDSetNvSciSyncObjforEOF() currently may be called only once before each call to NvMediaIJPDRender(). The application may choose to call this function only once before the first call to NvMediaIJPDRender().

Precondition: NvMediaIJPDRegisterNvSciSyncObj()

Postcondition: NvSciSyncObj to be used as EOF NvSciSyncFence is set

Usage considerations

Allowed context for the API call
- Interrupt handler: No
- Signal handler: No
- Thread-safe: Yes, with the following conditions
  - Every thread should be invoked with relevant NvMediaIJPD object.
- Re-entrant: No
- Async/Sync: Sync
Required privileges: None
API group
- Init: No
- Runtime: Yes
- De-Init: No

Note: This API is mandatory when multiple engines are pipelined in order to achieve synchronization between the engines

Parameters

[in]	decoder	A pointer to the NvMediaIJPD object. Input range: Non-NULL - valid pointer address
[in]	nvscisyncEOF	A registered NvSciSyncObj which is to be associated with EOF NvSciSyncFence. Input range: A valid NvSciSyncObj

Returns

NvMediaStatus The status of the operation. Possible values are:

NVMEDIA_STATUS_OK if the function is successful.
NVMEDIA_STATUS_BAD_PARAMETER if decoder is NULL, or if nvscisyncEOF is not registered with decoder as either type NVMEDIA_EOFSYNCOBJ or NVMEDIA_EOF_PRESYNCOBJ.

◆ NvMediaIJPDUnregisterNvSciBufObj()

NvMediaStatus NvMediaIJPDUnregisterNvSciBufObj	(	const NvMediaIJPD *	decoder,
		NvSciBufObj	bufObj
	)

Un-registers NvSciBufObj which was previously registered with NvMediaIJPD using NvMediaIJPDRegisterNvSciBufObj().

For all NvSciBufObj handles registered with NvMediaIJPD using NvMediaIJPDRegisterNvSciBufObj API, NvMediaIJPDUnregisterNvSciBufObj must be called before calling NvMediaIJPDDestroy API. For unregistration to succeed, it should be ensured that none of the submitted tasks on the bufObj are pending prior to calling NvMediaIJPDUnregisterNvSciBufObj(). In order to ensure this, NvMediaIJPDUnregisterNvSciSyncObj() should be called prior to this API on all registered NvSciSyncObj. Post this NvMediaIJPDUnregisterNvSciBufObj() can be successfully called on a valid NvSciBufObj.

This needs to be used in tandem with NvMediaIJPDRegisterNvSciBufObj(). The pair of APIs for registering and unregistering NvSciBufObj are optional, but it is highly recommended to use them as they ensure deterministic execution of NvMediaIJPDRender().

To ensure deterministic execution time of NvMediaIJPDRender API:

NvMediaIJPDUnregisterNvSciBufObj should be called only after the last NvMediaIJPDRender call

Note: This API is currently not supported and can be ignored

Precondition: NvMediaIJPDUnregisterNvSciSyncObj() [verify that processing is complete]

Postcondition: NvSciBufObj is un-registered from NvMediaIJPD object

Usage considerations

Allowed context for the API call
- Interrupt handler: No
- Signal handler: No
- Thread-safe: Yes, with the following conditions
  - Every thread should be invoked with relevant NvMediaIJPD object.
- Re-entrant: No
- Async/Sync: Sync
Required privileges: None
API group
- Init: No
- Runtime: No
- De-Init: Yes

Parameters

[in]	decoder	A pointer to the NvMediaIJPD object. Input range: Non-NULL - valid pointer address
[in]	bufObj	NvSciBufObj object Input range: A valid NvSciBufObj

Returns

NvMediaStatus, the completion status of operation:

NVMEDIA_STATUS_NOT_SUPPORTED if API is not functionally supported

◆ NvMediaIJPDUnregisterNvSciSyncObj()

NvMediaStatus NvMediaIJPDUnregisterNvSciSyncObj	(	const NvMediaIJPD *	decoder,
		NvSciSyncObj	nvscisync
	)

Unregisters an NvSciSyncObj with NvMediaIJPD.

Every NvSciSyncObj registered with NvMediaIJPD by NvMediaIJPDRegisterNvSciSyncObj() must be unregistered before calling NvMediaIJPDUnregisterNvSciBufObj() to unregister the NvSciBufObjs.

Before the application calls this function, it must ensure that any NvMediaIJPDRender() operation that uses the NvSciSyncObj has completed. If this function is called while NvSciSyncObj is still in use by any NvMediaIJPDRender() operation, the API returns NVMEDIA_STATUS_PENDING to indicate the same. NvSciSyncFenceWait() API can be called on the EOF NvSciSyncFence obtained post the last call to NvMediaIJPDRender() to wait for the associated tasks to complete. The EOF NvSciSyncFence would have been previously obtained via a call to NvMediaIJPDGetEOFNvSciSyncFence(). The other option would be to call NvMediaIJPDGetBits() till there is no more output to retrieve.

Precondition: NvMediaIJPDRender(); NvMediaIJPDGetBits() or NvSciSyncFenceWait() [verify that processing is complete]

Postcondition: NvSciSyncObj un-registered with NvMediaIJPD

Usage considerations

Allowed context for the API call
- Interrupt handler: No
- Signal handler: No
- Thread-safe: Yes, with the following conditions
  - Every thread should be invoked with relevant NvMediaIJPD object.
- Re-entrant: No
- Async/Sync: Sync
Required privileges: None
API group
- Init: No
- Runtime: No
- De-Init: Yes

Note: This API is mandatory when multiple engines are pipelined in order to achieve synchronization between the engines

Parameters

[in]	decoder	A pointer to the NvMediaIJPD object. Input range: Non-NULL - valid pointer address
[in]	nvscisync	An NvSciSyncObj to be unregistered with decoder. Input range: A valid NvSciSyncObj

Returns

NvMediaStatus The status of the operation. Possible values are:

NVMEDIA_STATUS_OK if the function is successful.
NVMEDIA_STATUS_BAD_PARAMETER if decoder is NULL, or nvscisync is not registered with decoder.
NVMEDIA_STATUS_PENDING if the NvSciSyncObj is still in use, i.e., the submitted task is still in progress. In this case, the application can choose to wait for operations to complete on the output surface using NvSciSyncFenceWait() or re-try the NvMediaIJPDUnregisterNvSciBufObj() API call, until the status returned is not NVMEDIA_STATUS_PENDING.
NVMEDIA_STATUS_ERROR if decoder was destroyed before this function was called.
