Error Codes.

Enumerator
NV_ENC_SUCCESS 

This indicates that API call returned with no errors.

NV_ENC_ERR_NO_ENCODE_DEVICE 

This indicates that no encode capable devices were detected.

NV_ENC_ERR_UNSUPPORTED_DEVICE 

This indicates that devices pass by the client is not supported.

NV_ENC_ERR_INVALID_ENCODERDEVICE 

This indicates that the encoder device supplied by the client is not valid.

NV_ENC_ERR_INVALID_DEVICE 

This indicates that device passed to the API call is invalid.

NV_ENC_ERR_DEVICE_NOT_EXIST 

This indicates that device passed to the API call is no longer available and needs to be reinitialized.

The clients need to destroy the current encoder session by freeing the allocated input output buffers and destroying the device and create a new encoding session.

NV_ENC_ERR_INVALID_PTR 

This indicates that one or more of the pointers passed to the API call is invalid.

NV_ENC_ERR_INVALID_EVENT 

This indicates that completion event passed in NvEncEncodePicture() call is invalid.

NV_ENC_ERR_INVALID_PARAM 

This indicates that one or more of the parameter passed to the API call is invalid.

NV_ENC_ERR_INVALID_CALL 

This indicates that an API call was made in wrong sequence/order.

NV_ENC_ERR_OUT_OF_MEMORY 

This indicates that the API call failed because it was unable to allocate enough memory to perform the requested operation.

NV_ENC_ERR_ENCODER_NOT_INITIALIZED 

This indicates that the encoder has not been initialized with NvEncInitializeEncoder() or that initialization has failed.

The client cannot allocate input or output buffers or do any encoding related operation before successfully initializing the encoder.

NV_ENC_ERR_UNSUPPORTED_PARAM 

This indicates that an unsupported parameter was passed by the client.

NV_ENC_ERR_LOCK_BUSY 

This indicates that the NvEncLockBitstream() failed to lock the output buffer.

This happens when the client makes a non blocking lock call to access the output bitstream by passing NV_ENC_LOCK_BITSTREAM::doNotWait flag. This is not a fatal error and client should retry the same operation after few milliseconds.

NV_ENC_ERR_NOT_ENOUGH_BUFFER 

This indicates that the size of the user buffer passed by the client is insufficient for the requested operation.

NV_ENC_ERR_INVALID_VERSION 

This indicates that an invalid struct version was used by the client.

NV_ENC_ERR_MAP_FAILED 

This indicates that NvEncMapInputResource() API failed to map the client provided input resource.

NV_ENC_ERR_NEED_MORE_INPUT 

This indicates encode driver requires more input buffers to produce an output bitstream.

If this error is returned from NvEncEncodePicture() API, this is not a fatal error. If the client is encoding with B frames then, NvEncEncodePicture() API might be buffering the input frame for re-ordering.

A client operating in synchronous mode cannot call NvEncLockBitstream() API on the output bitstream buffer if NvEncEncodePicture() returned the NV_ENC_ERR_NEED_MORE_INPUT error code. The client must continue providing input frames until encode driver returns NV_ENC_SUCCESS. After receiving NV_ENC_SUCCESS status the client can call NvEncLockBitstream() API on the output buffers in the same order in which it has called NvEncEncodePicture().

NV_ENC_ERR_ENCODER_BUSY 

This indicates that the HW encoder is busy encoding and is unable to encode the input.

The client should call NvEncEncodePicture() again after few milliseconds.

NV_ENC_ERR_EVENT_NOT_REGISTERD 

This indicates that the completion event passed in NvEncEncodePicture() API has not been registered with encoder driver using NvEncRegisterAsyncEvent().

NV_ENC_ERR_GENERIC 

This indicates that an unknown internal error has occurred.

NV_ENC_ERR_INCOMPATIBLE_CLIENT_KEY 

This indicates that the client is attempting to use a feature that is not available for the license type for the current system.

NV_ENC_ERR_UNIMPLEMENTED 

This indicates that the client is attempting to use a feature that is not implemented for the current version.

NV_ENC_ERR_RESOURCE_REGISTER_FAILED 

This indicates that the NvEncRegisterResource API failed to register the resource.

NV_ENC_ERR_RESOURCE_NOT_REGISTERED 

This indicates that the client is attempting to unregister a resource that has not been successfully registered.

NV_ENC_ERR_RESOURCE_NOT_MAPPED 

This indicates that the client is attempting to unmap a resource that has not been successfully mapped.
