[FFmpeg-user] how to transcode mp4 file into hls stream

[qw]

Hi,
 
I use the following command to do transcoding from mp4 file into hls stream:
 
ffmpeg -y -i input.mp4 -vbsf h264_mp4toannexb -c:v libx264 -c:a libfdk_aac -f hls -hls_list_size 10 -hls_wrap 10 ./output.m3u8
 
Then ffmpeg outputs 10 ts files, but there is big different between the size of 10 ts files.
