我正在尝试使用 ffmpeg 命令添加软字幕
ffmpeg -y -i test1/r.avi -c:v libx264 -map v:0 -map a:0 -map 1 r.avi
但我收到以下错误：
[avi @ 0x55d2e8c30d20] Subtitle streams other than DivX XSUB is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.
Could not write header for output file #0 (incorrect codec parameters ?): Not yet implemented in FFmpeg, patches welcome
Error initializing output stream 0:0 --
[libmp3lame @ 0x55d2e8c394c0] 4 frames left in the queue on closing
知道我做错了什么吗
答案1
尝试将 SRT（subrip）字幕添加到 AVI 容器时也发现了同样的错误（未实现除 DivX XSUB 之外的字幕流...）。
1）无需重新编码，将 AVI 转换为 MKV 容器：
ffmpeg -fflags +genpts -i input.avi -c:v copy -c:a copy output.mkv
2) 将字幕添加到 mkv 容器（上一步中的“output.mkv”）。例如：
ffmpeg -i output.mkv -i input.srt -c copy -c:s srt "output-sub.eng.mkv"
