`unreal.AjaMediaOutput`¶

class unreal.AjaMediaOutput(outer: Object | None = None, name: Name | str = 'None')¶

Bases: 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)

audio_buffer_size (int32): [Read-Write] Size of the buffer that holds rendered audio samples, a bigger buffer will produce a more stable output signal but will introduce more delay.
audio_sample_rate (AjaMediaOutputAudioSampleRate): [Read-Write] Audio output sample rate.
encode_timecode_in_texel (bool): [Read-Write] Burn Frame Timecode on the output without any frame number clipping.
hdr_options (AjaMediaHDROptions): [Read-Write] HDR Metadata of the video signal.
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.
num_output_audio_channels (AjaMediaOutputChannelConfiguration): [Read-Write] Number of audio channels used when output audio on the card.
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_audio (bool): [Read-Write] Whether to capture and output audio from the engine.
output_audio_on_audio_thread (bool): [Read-Write] Whether to output audio on the audio thread instead of the rendering thread. Only available in Ping Pong mode. (Experimental)
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_interlace_as_progressive (bool): [Read-Write] If this is enabled when outputting media in interlace format, frames will be treated as progressive and will be outputted as-is. (Experimental)
output_interlace_on_even_frames (bool): [Read-Write] Whether to only schedule interlace frames if we land on an even timecode. Useful when you have an interlace input and want to ensure that we interlace the original frames. (Experimental)
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.
stop_output_on_card_timeout (bool): [Read-Write] If this is disabled, output will keep going even if we hit a timeout when waiting for a vertical interrupt from the card.
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.
