我正在尝试使用 Kdenlive 渲染垂直高清 30 fps 视频。
但是，无论我选择哪种输出格式（GIF HQ、MP4-H264/AAC、MPEG-2、Matroska-H264/AAC、WebM-VP8/Vorbis），渲染都会崩溃。
记录以下错误：

我使用的是 Arch Linux ( 6.3.8-arch1-1)。
我的系统上确实缺少错误日志中提到的特定版本的共享对象文件：
$ ls /usr/lib/(libopencv_tracking|libavformat|libvidstab).so*
/usr/lib/libavformat.so@ /usr/lib/libavformat.so.58.76.100* /usr/lib/libavformat.so.60.3.100* /usr/lib/libopencv_tracking.so.407@ /usr/lib/libvidstab.so@
/usr/lib/libavformat.so.58@ /usr/lib/libavformat.so.60@ /usr/lib/libopencv_tracking.so@ /usr/lib/libopencv_tracking.so.4.7.0* /usr/lib/libvidstab.so.1.2*
安装了以下软件包版本：
$ yay -Q kdenlive opencv ffmpeg ffmpeg4.4 mlt mlt6
kdenlive 23.04.2-1
opencv 4.7.0-12
ffmpeg 2:6.0-8
ffmpeg4.4 4.4.4-1
mlt 7.16.0-1
mlt6 6.26.1-10
我不确定这是否会导致渲染崩溃（例如，我没有使用任何 OpenCV 跟踪）。我找不到有关其他错误的任何相关信息。
答案1
卸载该mlt6软件包解决了该问题。
