    I'm not at all familiar with Visionlib. You might want to reach out to its support. NatCorder works entirely independently; it doesn't interfere with other system processes except using the hardware encoders.

    Any update on the release date? We are currently delaying a launch waiting for the fix.

    What device does this happen on? You say your video freezes, what video? Please be exact when describing issues like this.

    I have the same issue. It will not record audio. I reached out to the developer and was assured the 1.6.1 version would have a fix. Updated my project today with the latest version and it also does not work. Even just deploying the ReplayCam example to my Android phone crashes every time. I feel this is not tested thoroughly.

    My project is held up cause of this issue and I'll have to look into another solution. I am also doing an ARCore app, so I need to essentially screen capture the session and capture and the audio as well. Seems if I enable the microphone the app freezes. Without that checked it records fine. I am testing on a Galaxy S7 and a Note 9.

    I used the NatCorder plugin back when it was 1.2 and had no issues. However the latest iterations feel unfinished. Even the Asset Store has links to the documentation, which takes you to the 1.3 version!

    I wasn't able to reproduce a crash when recording audio on the ReplayCam example. There was definitely a sporadic crash when trying to record audio in 1.6.0, an issue which we explicitly fixed. Crashes are a manifestation of potentially very different underlying causes (for instance, it could be a permissions issue which is trivial). I never asked for a crash log from you to confirm that this was in fact the same issue as the other one we fixed, so my bad on that. Email me the full (unfiltered) logs from logcat in a .txt file.
    Definitely sounds like permissions. The ReplayCam example intentionally runs a hot loop until the microphone has started.
    Because of the microphone issue? Please expatiate.
    We have been deliberating entirely removing the online docs, because the asset itself includes docs (and those are always updated, you can verify this by opening index.html in NatCorder > Docs). To avoid confusion, I'll remove all online docs now.

    NatCorder 1.6.1 has significant performance improvements when recording from a RenderTexture (and reflexively, when recording from a game camera) on iOS and Android:

    1.5.1 (used Texture2D.ReadPixels):
    1.5.1.png
    1.6.0 (used AsyncGPUReadback):

    1.6.1 (uses our custom Metal texture readback):

    I updated to the new v1.6.1, but I'm facing an issue with it. When executing the example ReplayCam, everything works fine and the recording is saved. But when playing the scene again in the editor, it becomes stuck and is necessary to use Task Manager to kill the process and restart Unity. I've re-imported the plugin to discard any external issues, and it still has the same behaviour.
    Thanks for your help with this problem.

    When starting to record in Android, it immediately crashes. Attached is the resulting log.

    Thank you for your hard work! Just updated to 1.6.1 and see the tremendous performance improvements. Unfortunately, also facing a few issues:

    1) There is a 1-2 second lag on-device (in this case an iPhone X) when starting each video record session. This breaks AR tracking and leads to a bad user experience. For this reason alone I have to keep using NatCorder 1.4, where there is lag at the start of only the first record session, which can be worked around by starting and stopping a session on app startup and disposing the video.

    2) This update now causes Unity to hang when doing the following: press play in editor to start app > record video > stop recording video > press play to stop app > press play again to start app > Unity hangs. This is with 2018.4.4 on MacOS 10.14.5, build target iOS. Starting and stopping multiple record sessions in a row on device, however, works fine.

    Awesome update!

    I tested it on a build, worked like a charm. But archiving it results in undefined symbols for armv7. Is it possible to get a build that has support for this, or is there some other workaround? I know support will be dropped in the future, but we still have users on armv7 :)

    Ah I think I know why this happens. Just to confirm my suspicion, open Player Settings and disable multithreaded rendering. Let me know if it still crashes (it shouldn't).

    I can't reproduce this. I get some lag on the first recording, but this is unavoidable as the encoder is starting up. But on subsequent recordings, there is no lag. Also the first lag is nowhere close to 1-2 seconds, more like a few hundred milliseconds (recording 1920x1080 at 60FPS).
    I'll look into this.

    We build for iOS 11, which doesn't support building armv7 slices. Armv7 has been officially deprecated by Apple for a while now, and the market share reflects this very much.

    it works now.

    But the audio sounds really bad, playing saved video, console prints lots of "AudioSampleProvider buffer overflow. 1216 sample frames discarded."

    NatCorder shows this when recording:

    Found the culprit: was calling iPhoneSpeaker.ForceToSpeaker() before recording, which combined with NatCorder / NatMic leads to the delay. Need to test more to see if its ok to remove this line, but without it record delay is minimal, which preserves AR tracking :)

    I am, however, having issues with data synchronization because the new API no longer allows us to manually commit timestamps. Am I missing something or has it been removed?

    Thanks again!

    The NatCorder logs look normal. Are you running the ReplayCam example?

    EDIT: What audio are you recording? You channel count is 1 (mono), which is not a conventional setting when recording Unity game audio.

    What do you mean the new API doesn't allow to commit timestamps? None of this has changed (see the Changelog for a list of changes between versions).

    This is my setup:

    Code (CSharp):
    1.  
    2.         NatCorderMP4Recorder = new MP4Recorder(
    3.             Ancho,
    4.             Alto,
    5.             30,
    6.             AudioSettings.outputSampleRate,
    7.             (int)AudioSettings.speakerMode,
    8.             OnVideo,
    9.             2340000
    10.         );
    And this is where i get the audio data:
    Code (CSharp):
    1.  
    2.     private void OnAudioFilterRead(float[] data, int channels) {
    3.         if (Recording) {
    4.             NatCorderMP4Recorder.CommitSamples(data, recordingClock.Timestamp);
    5.             if (mute) Array.Clear(data, 0, data.Length);
    6.         }
    7.     }

    Are you forcing Unity to produce mono audio?

    hi, I have a problem with recording the screen. when I record 3-4 times, the app will just freeze, the background music is still playing but the screen is freeze. This only happened to new iPad pro (11inch)
    the Natrecorder version I used is 1.4.0, I also tried 1.6.1 but it was the same result.

    I have attached the log from iOS.
    Thank you!

    Can you try 1.6.1 and send the logs? The code for 1.6.1 and 1.4.0 aren't the same.

    Hi, nice update, thank you
    But i have same issue about editor crash, i have disabled the multithread rendering but it still crashed.

    How to reproduce this issue:

    - Press play in editor to start app > record video > stop recording video > press play again in editor > Unity hangs. This is with 2018.3.14f1 on Win 10, build target android.

    I am still facing that issue too, disabling multithread rendering only solves Android crash.

    When using the ReplayCam example, I'm getting an error when recording with the microphone (audio) on. I've tested two cases, the first is without using the microphone, which creates the video well and can be shared without problem. But when recording with the mic on, the file is created, but at the moment of sharing it (for example Facebook or Whatsapp) the file cannot be played. To further prove this, when running the following command "ffmpeg.exe -v error -i video.mp4 -f null - >error.log 2>&1", it can be seen that the file is partially corrupt.

    Again, Android..

    Log with mic off:

    first the API in this article is irrelevant for experiments with live camera : https://medium.com/@olokobayusuf/natcorder-unity-recording-made-easy-f0fdee0b5055
    since it doesnt work out of the box.

    you samples in the plugin have a different namespace. and i cant seem to make it work (i have now tried to update again and things got damaged).

    third, a lot of people here are facing issues with making this to work on mobile and then on AR. i am willing to pay 5-10 dollar more if you make an example showing this!
    or maybe even better for you- make another plugin as such example (that depends on having this one).

    i hope you take these as suggestions, rather than critic. i really want this plugin to work but right now im stuck.

    The editor issue is separate from the one on Android. I have submitted an update that fixes the crash on Android.

    This issue is explicitly from Unity as far as I can tell (GetNativeTexturePtr is crashing). File a bug report with Unity.

    Are you using 1.6.1?
    I've updated the code (it was for NatCorder 1.5, forgot to update it to the 1.6 API).
    We renamed the overarching namespace to `NatCorder` in 1.5 (see the Changelog.md where we keep a comprehensive list of changes) and it hasn't changed (and will not change).
    An example showing what? A lot of developers use NatCorder with ARKit, ARCore, and Vuforia. Using NatCorder with any of these is as simple as modifying the ReplayCam code to record their AR game camera (instead of Camera.main).

    Yes, I can even play it inside unity with a videoplayer but at the end of the video, it starts spamming "AudioSampleProvider buffer overflow"

    Bravo on performance!
    After the degrade in performance in 1.6 this is great...
    I'm adding my voice to the fact that Unity Editor is stuck after recording, stopping and pressing play again... does seems to work good on android though.

    Alright, I'm attempting to see if the 1.6.1 update would help, but I'm seeing compilation errors when importing in updated natcorder scripts.

    Assets/3rd Party/NatCorder/Plugins/Managed/Internal/AsyncGPUReadback.cs(19,13): error CS0103: The name 'Dispatcher' does not exist in the current context

    Is there another auxiliary package I need to install? Doesn't appear to be using the .Net dispatcher, as we are using the latest .net settings

    Always delete NatCorder in your project before importing an update from the Asset Store.

    hi guys and lanre :),
    so i also updated to 1.6.1
    running the sample out of the box on the Editor and it works.
    made an android build, the video is recorded and replayed, but i cant find the file on the phone. does anybody know where to look? i found the com.XXX.YYY folder, in the Android\data\ folder, but its not there.

    does anybody managed to bring it to the gallery?

    NatCorder always records to the app's private documents directory. You can use NatShare API (it's open source) to copy the video to the camera roll on mobile platforms.

    Thanks, after fixing that, I found a workaround to make the two systems work together. It involves two cameras, the first for the Real work background, and the second for the culled out AR objects. The first one with the background is for some reason twisted 90* counterclockwise and only on device. It stretches to fit the video size as well I can email a video of the effect if needed. Looks like the issue stops if I only use one camera. Seen on iOS working on getting an android to test reproducibility there

    I packaged the 32-bit exe under window platform. Why did the program flash back after recording.

    Are you aware of any issue(s) of Android crashing when recording using a combination of NatCam (1.6) and NatCorder (2.2.1)?

    Have tested on two different devices (different in performance) and sometime after roughly 17 seconds of recording the app simply dies, both in our actual project as well in new, clean, project. Have used both the InputCamera class as well as a "copied" implementation of its "CommitFrame" that use a Texture instead of a RenderTexture. Both implementations will crash after a certain recording period has elapsed.

    NatCorder doesn't support 32-bit on standalone platforms (Windows or macOS).

    Use NatCam's CaptureFrame method to get the preview data, then commit that preview data directly. Can you share your code?
