How to setup Socks proxy?

[bucky0970]

I saw rtmp.c has options for socks, but I do not know where to enable this option?

static struct urlopt {
    AVal name;
    off_t off;
    int otype;
    int omisc;
    char *use;
} options[] = {
    {AVC("socks"), OFF(Link.sockshost), OPT_STR, 0,
     "Use the specified SOCKS proxy"},
    {AVC("app"), OFF(Link.app), OPT_STR, 0,
     "Name of target app on server"},
    {AVC("tcUrl"), OFF(Link.tcUrl), OPT_STR, 0,
     "URL to played stream"},
    {AVC("pageUrl"), OFF(Link.pageUrl), OPT_STR, 0,
     "URL of played media's web page"},
    {AVC("swfUrl"), OFF(Link.swfUrl), OPT_STR, 0,
     "URL to player SWF file"},
    {AVC("flashver"), OFF(Link.flashVer), OPT_STR, 0,
     "Flash version string (default " DEF_VERSTR ")"},
    {AVC("conn"), OFF(Link.extras), OPT_CONN, 0,
     "Append arbitrary AMF data to Connect message"},
    {AVC("playpath"), OFF(Link.playpath), OPT_STR, 0,
     "Path to target media on server"},
    {AVC("playlist"), OFF(Link.lFlags), OPT_BOOL, RTMP_LF_PLST,
     "Set playlist before play command"},
    {AVC("live"), OFF(Link.lFlags), OPT_BOOL, RTMP_LF_LIVE,
     "Stream is live, no seeking possible"},
    {AVC("subscribe"), OFF(Link.subscribepath), OPT_STR, 0,
     "Stream to subscribe to"},
    {AVC("token"), OFF(Link.token), OPT_STR, 0,
     "Key for SecureToken response"},
    {AVC("swfVfy"), OFF(Link.lFlags), OPT_BOOL, RTMP_LF_SWFV,
     "Perform SWF Verification"},
    {AVC("swfAge"), OFF(Link.swfAge), OPT_INT, 0,
     "Number of days to use cached SWF hash"},
    {AVC("start"), OFF(Link.seekTime), OPT_INT, 0,
     "Stream start position in milliseconds"},
    {AVC("stop"), OFF(Link.stopTime), OPT_INT, 0,
     "Stream stop position in milliseconds"},
    {AVC("buffer"), OFF(m_nBufferMS), OPT_INT, 0,
     "Buffer time in milliseconds"},
    {AVC("timeout"), OFF(Link.timeout), OPT_INT, 0,
     "Session timeout in seconds"},
    {{NULL, 0}, 0, 0}};

I found here can do setting. in LFStreamRtmpSocket.m at Top static const AVal av_sockhost = AVC("127.0.0.1"); and modify this method,add Link.sockshost and Link.socksport.

- (NSInteger)RTMP264_Connect:(char *)push_url {
    //由于摄像头的timestamp是一直在累加，需要每次得到相对时间戳
    //分配与初始化
    _rtmp = PILI_RTMP_Alloc();
    PILI_RTMP_Init(_rtmp);

    //设置URL
    if (PILI_RTMP_SetupURL(_rtmp, push_url, &_error) == FALSE) {
        //log(LOG_ERR, "RTMP_SetupURL() failed!");
        goto Failed;
    }

    _rtmp->m_errorCallback = RTMPErrorCallback;
    _rtmp->m_connCallback = ConnectionTimeCallback;
    _rtmp->m_userData = (__bridge void *)self;
    _rtmp->m_msgCounter = 1;
    _rtmp->Link.timeout = RTMP_RECEIVE_TIMEOUT;
    _rtmp->Link.sockshost = av_sockhost;
    _rtmp->Link.socksport = 60111;

    //设置可写，即发布流，这个函数必须在连接前使用，否则无效
    PILI_RTMP_EnableWrite(_rtmp);

    //连接服务器
    if (PILI_RTMP_Connect(_rtmp, NULL, &_error) == FALSE) {
        goto Failed;
    }

    //连接流
    if (PILI_RTMP_ConnectStream(_rtmp, 0, &_error) == FALSE) {
        goto Failed;
    }

    if (self.delegate && [self.delegate respondsToSelector:@selector(socketStatus:status:)]) {
        [self.delegate socketStatus:self status:LFLiveStart];
    }

    [self sendMetaData];

    _isConnected = YES;
    _isConnecting = NO;
    _isReconnecting = NO;
    _isSending = NO;
    return 0;

Failed:
    PILI_RTMP_Close(_rtmp, &_error);
    PILI_RTMP_Free(_rtmp);
    _rtmp = NULL;
    [self reconnect];
    return -1;
}

After run the code, it seems to be setting make different. But it shows

ERROR: PILI_RTMP_Connect0, SOCKS negotiation failed.
liveStateDidChange: 1
ERROR: PILI_RTMP_Connect0, SOCKS negotiation failed.
liveStateDidChange: 5
ERROR: PILI_RTMP_Connect0, SOCKS negotiation failed.
liveStateDidChange: 5

I will keep trying,If anyone can help me with this,it would be great...
