我试图从原始的2字节灰色视频（以16位值编码的14位范围）生成h.264视频。我可以这样做：
ffmpeg -f rawvideo -pix_fmt gray16le -s:v 1280x720 -r 60 -i input.raw -c:v libx264 output.mp4
我得到了视频，但它很暗，不确定它是否剪辑，进行线性重映射，或存储16位数据和VLC正在进行重映射。 ffprobe正在报告Video: h264 (High 4:4:4 Predictive) (avc1 / 0x31637661), yuvj444p(pc), 1280x720, 108 kb/s, 60 fps, 60 tbr, 15360 tbn, 120 tbc
我在想我是否会使用色调图滤镜来制作更好的贴图。我在输出文件-vf之前添加了一个过滤器。
