2.  push stream by ffmpeg

ffmpeg -f mpegts -re -i war.ts -c:v libx264 -s 640x360 -c:a libfdk_aac -ar 48000 -f flv rtmp://localhost/hls/test1

ffmpeg -f mpegts -re -i war.ts -c:v libx264 -s 640x360 -c:a libmp3lame -ar 48000 -f flv rtmp://localhost/hls/test

Notes: As far as mp3, flv not support mp3 with sample rate 48000. Following errors will be output.

[flv @ 0x96e340] FLV does not support sample rate 48000, choose from (44100, 22050, 11025)
[flv @ 0x96e340] Audio codec mp3 not compatible with flv

If you change its sample rate from 48000 to 44100 as followings, it will be work normally.

ffmpeg -f mpegts -re -i war.ts -c:v libx264 -s 640x360 -c:a libmp3lame -ar 44100 -f flv rtmp://localhost/hls/test

3. pull stream by vlc
