unreal.AjaMediaOutput

class unreal.AjaMediaOutput(outer=None, name='None')

Bases: unreal.MediaOutput

Output information for an aja media capture. note: ‘Frame Buffer Pixel Format’ must be set to at least 8 bits of alpha to enabled the Key. note: ‘Enable alpha channel support in post-processing’ must be set to ‘Allow through tonemapper’ to enabled the Key.

C++ Source:

• Plugin: AjaMedia

• Module: AjaMediaOutput

• File: AjaMediaOutput.h

Editor Properties: (see get_editor_property/set_editor_property)

• encode_timecode_in_texel (bool): [Read-Write] Burn Frame Timecode on the output without any frame number clipping.

• interlaced_fields_timecode_need_to_match (bool): [Read-Write] Only make sense in interlaced mode. When creating a new Frame the 2 fields need to have the same timecode value. The Engine’s need a TimecodeProvider (or the default system clock) that is in sync with the generated fields.

• invert_key_output (bool): [Read-Write] Invert Key Output

• log_drop_frame (bool): [Read-Write] Log a warning when there’s a drop frame.

• number_of_aja_buffers (int32): [Read-Write] Number of frame used to transfer from the system memory to the AJA card. A smaller number is most likely to cause missed frame. A bigger number is most likely to increase latency.

• number_of_texture_buffers (int32): [Read-Write] Number of texture used to transfer the texture from the GPU to the system memory. A smaller number is most likely to block the GPU (wait for the transfer to complete). A bigger number is most likely to increase latency. note: Some Capture are not are executed on the GPU. If it’s the case then no buffer will be needed and no buffer will be created.

• output_configuration (MediaIOOutputConfiguration): [Read-Write] The device, port and video settings that correspond to the output.

• output_in3g_level_b (bool): [Read-Write] If the video format is compatible with 3G Level A, do the conversion to output in LevelB.

• output_with_auto_circulating (bool): [Read-Write] The output of the Audio, Ancillary and/or video will be perform at the same time. This may decrease transfer performance but each the data will be sync in relation with each other.

• pixel_format (AjaMediaOutputPixelFormat): [Read-Write] Native data format internally used by the device before being converted to SDI/HDMI signal.

• timecode_format (MediaIOTimecodeFormat): [Read-Write] Whether to embed the Engine’s timecode to the output frame.

• wait_for_sync_event (bool): [Read-Write] Try to maintain a the engine “Genlock” with the VSync signal.
