ffmpeg 添加-bsf:a   aac_adtstoasc 参数的方法

bsf：表示binary  steam fiter

a：表示audio

找到srs对应的配置文件，在配置文件里面添加aparams，在aparams里面添加aac_adtstoasc。

一个配置例子如下：

listen              1935;

max_connections     1000;

pid                 objs/edge.pid;

srs_log_file        ./objs/edge.log;

#vhost __defaultVhost__ {

#    mode            remote;

##    origin          127.0.0.1:19350;

#    origin           103.242.147.227:1935;

#}

vhost __defaultVhost__ {

#    mode            remote;

#    origin          58.218.152.98:1935;

ingest livestream {

enabled      on;

input {

#   file: ingest file specifies by url.

#   stream: ingest stream specifeis by url.

#   device: not support yet.

# default: file

type    stream;

# the url of file/stream.

url http://live.hkstv.hk.lxdns.com/live/hks/playlist.m3u8;

}

# the ffmpeg

ffmpeg      /tmp/ffmpeg;

# the transcode engine, @see all.transcode.srs.com

# @remark, the output is specified following.

engine {

enabled         on;

vcodec          copy;

acodec          copy;

aparams

{

profile:a   aac_low;

bsf:a       aac_adtstoasc;

}

output          rtmp://127.0.0.1:1935/live/livestream;

}

}

hls {

enabled         on;

hls_fragment    10;

hls_window      60;

hls_path        ./objs/nginx/html;

hls_m3u8_file   [app]/[stream].m3u8;

hls_ts_file     [app]/[stream]-[seq].ts;

}

}

http_server {

enabled         on;

listen          8088;

dir             ./objs/nginx/html;

}

srs指定这个文件ffmpeg就可以带参数-bsf:a   aac_adtstoasc 转码
