    Hello,

    I'm playing with augmented reality in Unity (I use EasyAR SDK). I found some sample projects on youtube and started learning (About: playing video on an image target)

    Everything works fine in Unity, but when I export the skd and try the application on my android phone, the video on Quad freezes suddenly. There is no any error for other functions of the application. Only the video freezes sometimes and suddenly.

    I also changed the transcoding settings of my video, I changed the codec, I reduced the resolution again, nothing has changed. I tried to run with another video, but the result has not changed too. My video always freezes...

    My Video Player settings are as attached.

    Thanks for your help.

    Hi!

    It sounds like you should submit a bug so we can have a look at the situation. There probably is something specific about the video(s) you are using that are causing the problem. For instance, maybe there is a bad interaction between Unity and the movie's frame rate (transcoding doesn't change this).

    You can try with other movies to see if the problem is generalized or specific to the movie you're working with.

    You can also experiment with the VideoPlayer properties "Wait for First Frame" and "Skip on Drop". Enabling "Wait for First Frame" will make sure the first frame of the movie has been decoded before starting to run the clock. Enabling "Skip on Drop" will cause the VideoPlayer to skip ahead when it finds it's late compared to the current time, and this may help unblock if something in the movie is causing trouble during decoding.

    To simplify the exploration, you should try to replicate the problem in isolation, using a new scene that just has a VideoPlayer on the main camera and plays the movie in one of the camera planes (near or far).

    Let us know what you find, and again, don't hesitate to submit a bug so we can help with the analysis and fix this for you if possible.

    Doesn't seem like the specific clip.

    You can find a bug report here. https://issuetracker.unity3d.com/is...video-clip-is-transcoded-on-android-9-devices

    I've tried lowering the resolution, bitrate, and the spatial quality. It seems that it's the transcoding. I'm using a .webm file to get transparency. If I don't transcode for Android playback is fine, except no transparency. If I transcode, I get the transparency but playback is truly awful. There currently seems like no way of developing an Android app with Unity that handles video with alpha in an acceptable way.

    That bug report says lowering the resolution fixes it. So maybe it’s something else?

    i am using unity video player and video is freezing on 2 or 3 sec. even i play video in new scene with camera near plane rendering mode video work fine in desktop but in android device this problem is occure i am using 1080p .mp4 video in 30 fps than i realize when i use video resolution higher than device screen size it with freez so i use 720p video and it works, so you need to choose multipal videos for diffrent screen size and choose dynamically according to device screen size
