The issue

Hello. I’m still using AVPro Video – Core Edition (2.9.3 · March 11, 2024).
I’m experiencing the following issues when playing videos:

1. Although the orientation appears correct in your MediaPlayer, the actual Texture is flipped, so I have to use “Resolve To RenderTexture,” as you suggested here. However, this consumes significant resources, which heavily impacts performance because...

2. My videos play at 240 FPS, and when I either press Play or perform a Seek, the frames take a long time to load.

I need to receive the Texture (ideally a Texture2D) directly from your MediaPlayer in the correct orientation, and I also need smooth 240 FPS playback without freezes.
I’m working and testing on both Windows/Mac Editor and iPadOS.
Has this issue been fixed in the current 3.3.3 version so I can decide whether it’s worth upgrading?

I'd suggest testing using the free trial version, to make sure you are testing the exact same thing.

I'd suggest testing using the free trial version, to make sure you are testing the exact same thing.

I’ve tested different combinations of AVPro Video Core 2.9.3 and Trial 3.3.3 with Unity 6 and Unity 6.2 using 240 FPS videos.
In my main app, playback stutters occasionally, while in an empty test scene (where only the video is played) it usually runs smoothly — although there are still cases where the video visually lags, even though the playback time continues to advance without interruption.

Regarding the flip issue, I found that mediaPlayer.TextureProducer.RequiresVerticalFlip() indicates whether the video texture is upside down. In my case, it always reports that the texture is flipped, even though the video itself — both in the MediaPlayer preview and as a standalone file — looks perfectly fine. Why does this happen? Can you explain how this mechanism works?

I’m currently retrieving the texture using mediaPlayer?.TextureProducer?.GetTexture(), but it requires a short await delay before the texture is fully loaded. What’s the proper way to get a Texture2D directly — already in the correct orientation (not flipped) — without heavy processing or performance drops? Because ResolveToRenderTexture() is definitely expensive and adds a lot of per-frame overhead.

Adding an event listener and waiting for the FirstFrameReady event is the best way to wait for the video player to have started producing frames.

With AVPro Video 3 the texture output from the TextureProducer should be in the correct orientation. If this is not the case then please share your video with us so we can investigate further (please send to unitysupport@renderheads.com).

please share your video with us

Hello. I’ve sent you the video by email. So far, I haven’t had a single video that appears with the correct orientation - neither in the old nor in the new version of the plugin. This applies to videos recorded directly with the iPhone/iPad camera as well as those recorded through a third-party Unity plugin.

the best way to wait for the video player to have started producing frames

Could you please share the most reliable example code showing how to:

• load a video from a given filePath,
• retrieve all its metadata (duration, resolution, framerate, etc.),
• obtain a Texture2D in the correct orientation,
• and ensure smooth playback without freezes or delays (both when using Play and Seek)?

Any updates?

We've not been able to reproduce this using your video and AVPro Video version 3.3.3

How does it work for you? I’m just testing it on the trial version…

I added you to my test repository. Please take a look.
