ffmpeg - 如何使用 ffmpeg 为 wmv 和 avi 视频文件生成 m3u8 文件和 TS 段文件列表

Question

我能够生成 m3u8和来自 .ts 的段 (mp4) 文件列表视频文件使用以下 ffmpeg命令

ffmpeg -i Bee_Free.mp4 -codec copy -vbsf h264_mp4toannexb -map 0 -f segment -segment_list free.m3u8 -segment_time 10 free%03d.ts

我正在使用相同的命令来生成 m3u8和 ts来自 .wmv 的文件和 .avi文件
.avi 的命令文件
ffmpeg -i PalivalaBadraVatakam.avi -codec copy -vbsf h264_mp4toannexb -map 0 -f segment -segment_list palivaala.m3u8 -segment_time 10 palivaala%03d.ts

带有 TS 文件的 HLS 仅支持 h.264 视频编解码器和 aac 或 mp3 音频。因此 -codec 副本将不起作用。只需删除它，ffmpeg 应该会自动选择 libx264。
