Request by the PvSoftDeviceGEV to abort all buffers queued for acquisition.
This method should block until acquisition has been aborted or canceled for all buffers provided by QueueBuffer that have not yet been retrieved with RetrievedBuffer.
When this method returns, it should be possible to call RetrieveBuffer for all aborted buffers.
Implemented in PvStreamingChannelSourceDefault.

pure virtual |
Request by the PvSoftDeviceGEV to allocate a PvBuffer.
On initialization, the PvSoftDeviceGEV will call this method, asking the application to allocate buffers that will be used for image acquisition and transmission. The application should return buffers until it has reached the desired number of buffers it wants to use for streaming and then return NULL.
The more buffers you use, the more buffers you can have queued in the application for image acquisition and the more buffers you can leave in the transmission output queue for packet resend. The downside of using more buffers is increased memory usage.
Buffers returned on AllocBuffer calls should be unique: you should not return the same buffer more than once.
A maximum of 64 buffers can be used by one streaming channel of the PvSoftDeviceGEV. If your application does not return NULL on the 64th buffer, AllocBuffer will not be called a 64th time.
Implemented in PvStreamingChannelSourceDefault.

pure virtual |
Request by the PvSoftDeviceGEV to free or release a buffer allocated with AllocBuffer.
You should not delete or free any PvBuffer provided by the AllocBuffer method. FreeBuffer will be called for each buffer created with AllocBuffer when PvSoftDeviceGEV::Stop is called.
| [in] | aBuffer | Buffer to free. |
Implemented in PvStreamingChannelSourceDefault.

This method is requested by PvSoftDeviceGEV to limit the number of buffers used by the transmitter. It will be called before MySource->OnStreamingStart(). To specify a different number of buffers, override this method in your source and return an integer value aNumBuffer.
Typical Use Case: You may want to use different numbers of buffers for different frame rate or payload sizes during streaming. For example, if you have two scenarios requiring 40 and 8 buffers respectively, you must initialize your source buffer queue with 40 buffers. Then, inside this method returns 8 or 40 based on image size or frame rate .
Rules:
| [in] | aNumBuffer | The maximum number of buffers to be used by the transmitter. Valid range: 4 to number of buffer initialized. |
Implemented in PvStreamingChannelSourceDefault, and PvStreamingChannelSourceTrigger.
Request by the PvSoftDeviceGEV to queue a buffer for acquisition.
If the application can accept the buffer and queue it for image acquisition, it returns success. If the acquisition queue or pipeline is full, return a PvResult error code.
| [in] | aBuffer | Buffer to queue for image acquisition. |
Request by the PvSoftDeviceGEV to retrieve a buffer from the streaming source.
During acquisition, buffers retrieved with this method will contain valid image data and are going to be transmitted using the GVSP protocol. This method is also used to retrieve queued buffers after calling AbortQueuedBuffers.
If no image is immediately available, we recommend that you wait until an image is available in this method to allow the acquisition thread to wait efficiently for a new image. If getting a new image can take a long time, your application should wait small chunks of time (10, 20, or 50 ms) to prevent deadlocking the acquisition thread and to allow the PvSoftDeviceGEV to stop streaming gracefully.
| [in] | aBuffer | A pointer to a pointer to a buffer: set to a pointer to the PvBuffer being retrieved. |
