Ubuntu ffmpeg不能使用libx264

Question

命令

ffprobe rtsp://localhost/myvideo -codec:v libx264 -show_frames -of csv

输出

Failed to set value 'libx264' for option 'codec:v': Option not found

但似乎已经安装了libx264 - sudo apt install libx264-dev

libx264-dev is already the newest version (2:0.152.2854+gite9a5903-2).

Answer 1

libx264是一个编码器。ffprobe只探测和打印关于现有媒体输入的信息-没有指定编码器的范围。删除-codec:v libx264。
