Processing failed on some videos

[AEM120]

Video File: https://we.tl/t-pAhUdQeXmG

Open Safari, paste the link and download the video. Go to Files. Save Video to Photos. Using the Demo try to edit the video by cropping "square for example" only Then hit finish "Processing failed"

Some videos work fine, the video example that you have does not produce any issues. While the video example that I provided you have some issues when editing.

Example,

1. select the video, and crop it to square. click finish, you get processing failed.
2. select the video, and trim from the start. click finish, you get processing failed.

Please watch the following demo:

ok i will try to fix it

I been using different instruments to see where is the error. But it seems something to do with the EditorVideoCompositor. I also found out that some videos have full cpu usage when processing the edit

I found the problem, this is just a temporary solution

EditorVideoTool.swift

func insertAudioTrack(
        duration: CMTime,
        timeRang: CMTimeRange,
        audioTracks: [AVAssetTrack]
    ) throws 

Modify as follows

var audioInputParams: [AVMutableAudioMixInputParameters] = []
for audioTrack in audioTracks {
    guard let track = mixComposition.addMutableTrack(withMediaType: .audio, preferredTrackID: kCMPersistentTrackID_Invalid) else {
        continue
    }
    let audioTimeRange: CMTimeRange = .init(start: .zero, duration: .init(seconds: audioTrack.timeRange.duration.seconds - 0.5, preferredTimescale: audioTrack.timeRange.duration.timescale))
    try track.insertTimeRange(audioTimeRange, of: audioTrack, at: .zero)
    track.preferredTransform = audioTrack.preferredTransform
    let audioInputParam = AVMutableAudioMixInputParameters(track: track)
    audioInputParam.setVolumeRamp(fromStartVolume: factor.volume, toEndVolume: factor.volume, timeRange: audioTimeRange)
    audioInputParam.trackID = track.trackID
    audioInputParams.append(audioInputParam)
}
