使用AVAssetExportPresetPassthrough的AVAssetExportSession中断输出 [英] AVAssetExportSession using AVAssetExportPresetPassthrough breaking output

问题描述

我将AVAssetExportSession与AVAssetExportPresetPassthrough结合使用来将多个视频拼接在一起.一切工作都很好，除非在我的第一个子剪辑完成后，它的图片在最后一帧冻结"，但第二帧不播放.每个剪辑完成后，我确保将图层不透明度设置为0.0f，如果我使用另一个Preset-Type，则一切正常. 有提示吗?

I'm using AVAssetExportSession in combination with AVAssetExportPresetPassthrough to stitch multiple videos together. Everything works quite fine, except after my first sub-clip should have finished, it's picture "freezes" on the last frame but the second is not going to play. I made sure to set the layer opacity to 0.0f once each clip has finished, if I use another Preset-Type everything works... Any hints?

推荐答案
