How to add custom event to Media Player during play?

[getarobo]

hi

I have Image Sequence Source(0~300) and Media Player to control it.

I want this sequence to go to 240 and loop 121~240 until some bool becomes false. After that it will play through 300 and end.

I cant seem to find a way to trigger some event at 240th frame to seek media player to 121th frame.

Any ideas on doing this?

Thanks!

Hey @getarobo
Unfortunately Media Player doesn’t have a way to loop at a specific segment and continue when coding logic requires. Though due to your question I was testing running media player through sequencer and it kinda works. There are some weird glitches that exists but I believe you will be able to figure that out. I am sharing gifs to showcase that.

Hey @zer0chi!

Yeah I tried using sequencer and get the event but the problem was I needed sequencer to go back to certain point to loop. Ive been searching on how to do this but was unable to figure out.

I am looking into IMediaPlayer.cpp 's TickInput(). Engine seems to use this to trigger EndReached() event.

Thanks for the help! I will update on what I find

well I just added a Actor class that checks time of media player and handles the logic. OnEndReached didnt work for me for some reason so i just added my own.

I tried to override TickInput from imgmediaplay.h but cant figure this out

This might not be the most accurate solution but seems to work fine for my image sequence media player

.h
DECLARE_DYNAMIC_MULTICAST_DELEGATE_OneParam(FOnEndReached, int
...
class MY_API AMediaManager : public AActor
...
	PROPERTY(EditAnywhere, BlueprintReadWrite)
	UMediaPlayer * MediaPlayer;
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	bool LoopOn = true;
	UPROPERTY(EditAnywhere, BlueprintReadWrite)
	bool IsPlaying = false;
	UPROPERTY(BlueprintAssignable)
	FOnEndReached OnEndReached;


.cpp
void AMediaManager ::Tick(float DeltaTime)
{
	Super::Tick(DeltaTime);
	if(MediaPlayer && MediaPlayer->IsPlaying())
	{
		if(LoopOn && MediaPlayer->GetTime().GetTotalMilliseconds() > 8000)
		{
			ty0_MediaPlayer->Seek(FTimespan(0,0,4));
		}
		if(MediaPlayer->GetTime().GetTotalMilliseconds() > 10000)
		{
			MediaPlayer->Pause();
			isPlaying = false;
			OnEndReached.Broadcast(0);
		}
	}
}
