h264封装ts—ffmpeg的源码怎么用呢

打算对h264的es流进行ts封装，参考ffmpeg mpegtsenc.c的源码，mpegts_write_pes（）这个函数对es流打包成ts流，在这之前应该调用mpegts_init(),初始化AVFormatContext s类型变量，参考书明用s = avformat_alloc_context()，可是在mpegts_init()一开始就失败； 代码如下： AVFormatContext s = NULL; if (countProcess == 0) { pDataTs = (HI_U8 )malloc(sizeof(HI_U8) FRAMELEN); if (!pDataTs) { printf("%s:%d malloc false\n", FILE, LINE); return -1; }

        s = avformat_alloc_context();
        if (!s)
        {
            printf("%s:%d  avformat_alloc_context false\n", __FILE__, __LINE__);
            return -1;
        }
        countProcess = 1;
        printf("%s:%d\n", __FILE__, __LINE__);
        mpegts_init_ts(s);
        st = s->streams[0];
    }
    Is_IFrame = isIFrame_Sendpack(pDataAddr, u32DataLen, PackageType);
    key = Is_IFrame;
    memset(pDataTs, 0, sizeof(HI_U8) * FRAMELEN);
    printf("%s:%d\n", __FILE__, __LINE__);
    mpegts_write_pes(s, st, pDataAddr, u32DataLen, u32TimeStamp, u32TimeStamp, key, stream_id, pDataTs, &DataTsLen);
s32Ret = HI_RTP_SendSock(WriteSock, pDataTs, DataTsLen, pPeerSockAddr);

static int mpegts_init_ts(AVFormatContext *s) { printf("%s:%d\n", FILE, LINE);

MpegTSWrite *ts = s->priv_data;
 printf("%s:%d\n", __FILE__, __LINE__);
MpegTSWriteStream *ts_st;
MpegTSService *service;
AVStream *st, *pcr_st = NULL;
AVDictionaryEntry *title, *provider;
int i, j;
const char *service_name;
const char *provider_name;
int *pids;
int ret;

printf("%s:%d\n", __FILE__, __LINE__);
printf("%s:%d  ts->pes_payload_size:%d  s->max_delay:%d\n", __FILE__, __LINE__, ts->pes_payload_size, s->max_delay);

[color=Red] if (s->max_delay < 0) / Not set by t[/color]he caller / s->max_delay = 0;

// round up to a whole number of TS packets

[color=Red] ts->pes_payload_size = (ts->pes_payload_size [/color]+ 14 + 183) / 184 184 - 14; 在红字体这块就崩了，也就是说给mpegts_init_ts()的实参初始化有问题，可是源码没找见怎么调用mpegts_init（）给他的实参赋值， 群里的大神这个AVFormatContext s怎么赋值？[size=5][/size]
