ijkplayer怎么更精简的支持RTSP？

Created on 11 Nov 2016 · 18Comments · Source: bilibili/ijkplayer

1、我用module-default.sh是可以播放RTSP，但是打的包快500M，太大了。
2、现在是采用修改module-lite.sh文件，
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-protocol=rtp"
export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-demuxer=rtsp"
然后修改ff_ffplay.c文件，
修改：static int packet_queue_get_or_buffering(FFPlayer *ffp, PacketQueue *q, AVPacket *pkt, int *serial, int *finished)
{
assert(finished);
if (!ffp->packet_buffering)
return packet_queue_get(q, pkt, 1, serial);

while (1) {
    int new_packet = packet_queue_get(q, pkt, 0, serial);
    if (new_packet < 0)
        return -1;
    else if (new_packet == 0) {
        if (q->is_buffer_indicator && !*finished)
            ffp_toggle_buffering(ffp, 1);
        new_packet = packet_queue_get(q, pkt, 1, serial);
        if (new_packet < 0)
            return -1;
    }

    if (*finished == *serial) {
        av_packet_unref(pkt);
        continue;
    }
    else
        break;
}

return 1;

}

TO----->
static int packet_queue_get_or_buffering(FFPlayer *ffp, PacketQueue *q, AVPacket *pkt, int *serial, int finished)

{

while (1) {

    int new_packet = packet_queue_get(q, pkt, 1, serial);

    if (new_packet < 0)

    {

        new_packet = packet_queue_get(q, pkt, 0, serial);

        if(new_packet < 0)

        return -1;

    }
    else if (new_packet == 0) {

        if (!finished)

        ffp_toggle_buffering(ffp, 1);

        new_packet = packet_queue_get(q, pkt, 1, serial);

        if (new_packet < 0)

        return -1;

    }
    if (finished == *serial) {

        av_free_packet(pkt);

        continue;

    }
    else

    break;

}
return 1;

}

然后编译，打包播放不了，我从网上搜到的开源视频流地址：rtsp://218.204.223.237:554/live/1/66251FC11353191F/e7ooqwcfbqjoo80j.sdp

求大家指教！！！

./configure --help in ffmpeg's directory.

./configure --help in ffmpeg's directory. 能不能详细点，大神？

大神解决了没有。。求解释

哈哈,已经解决了,支持 rtsp,编译出来只有13M.

fengbenpaao on 28 Nov 2016

加入那几个之后,还不行,要把这个http的网络协议打开才行:# ./configure --list-protocols 这个地方全部开放, 不过也可以过滤掉一些,具体你可以试一下, 编完之后,查看config.h, 看看那个rtsp的宏是否已经打开了,

我现在测试 ,我的rtsp网络延时很慢,要5到6秒, 听说要改缓存, 正在查找....

fengbenpaao on 28 Nov 2016

另外还需要,注意你的视频,音频格式是否支持rtsp的播放, 网络缓存设置那个地方要加大,50ms, 似乎太短了

fengbenpaao on 28 Nov 2016

哈哈,不错, 在对 ijkMediaPlay 加点参数, 现在rtsp的码流播放速度很快啊, 没有延时.
