我填充 MP4 文件，然后将其转换为 GIF，但为什么 FFmpeg 将 gif 修剪为较短的视频？

ffmpeg -i Media1.mp4 -f lavfi -i anullsrc -c:v copy -af apad -t 5.83 Media1extended.mp4
ffmpeg -i Media1extended.mp4 -vf "split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 Media1extended.gif

怎样才能让它不被修剪呢？例如命令-autotrim 0

编辑：这是我的命令，它不起作用

ffmpeg -i Media1.mp4 -vf tpad=stop_mode=clone:stop_duration=5.83 Media1extended.mp4
ffmpeg -i Media1extended.mp4 -vf "split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse;tpad=stop_mode=clone:stop_duration=5.83" -loop 0 Media1extended.gif

Simple filtergraph 'split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse;tpad=stop_mode=clone:stop_duration=5.83' was expected to have exactly 1 input and 1 output. However, it had >1 input(s) and >1 output(s). Please adjust, or use a complex filtergraph (-filter_complex) instead.

编辑：这有效

ffmpeg -i Media1.mp4 -vf tpad=stop_mode=clone:stop_duration=5.83 Media1extended.mp4
ffmpeg -i Media1extended.mp4 -vf "split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -t 5.83 -loop 0 Media1extended.gif

此功能将 2 个视频放在顶部底部

ffmpeg -i input0 -i input1 -filter_complex vstack=inputs=2 output

我怎样才能在两者之间添加一些填充？我怎样才能堆叠 3 个视频呢？像这条线

ffmpeg -i input0 -i input1 -i input2 -filter_complex vstack=inputs=2 --padding-between-input 100,0 output
