video - FFMPEG 棕褐色滤镜

Question

似乎无法弄清楚为什么我的 colorchannelmixer 过滤器不能与 ffmpeg 一起工作。它似乎没有输出任何错误，但 ouput.mp4 视频只是一个没有缩略图的 0 秒长视频。

这是我正在尝试的命令。

ffmpeg -i video.mp4 -filter_complex \
"[0:v] colorchannelmixer=.393:.769:.189:0:.349:.686:.168:0:.272:.534:.131[f1];\
[f1] eq=1.0:0:1.3:2.4:1.0:1.0:1.0:1.0 [outv]" -map "[outv]" output.mp4

以及我收到的输出。

我遇到了同样的问题。我的问题是视频已生成但不支持在移动设备上播放。我通过将 -vcodec libx264 更改为 -vcodec mpeg4 解决了这个问题最终命令变为:"-threads 2 -y -i"+ initialFile + "-strict experimental -filter_complex [0:v]colorchannelmixer=.393:.769:.189:0:.349:.686: .168:0:.272:.534:.131[colorchannelmixed];[colorchannelmixed]eq=1.0:0:1.3:2.4:1.0:1.0:1.0:1.0[color_effect] -map [color_effect] -map 0:a -vcodec mpeg4 -crf 23 -b:v 1000K -maxrate 1500K -bufsize 500K"+ resultFile;
