用的最新的ffmpeg封装的

可以参考一下ffmpeg的doc/examples/muxing.c

HISI3516

嗯，但是我现在这边是直接给数据就发生[mp4 @ 0x23f7950] muxer does not support non seekable output这个错误

代码是否方便贴出来看一下

这是write的代码

HISI3516

        {
                //cout << "iBufSize :" << iBufSize << "frametype:" << frametype << "pBuffer" << pBuffer[0]<< endl;

                int64_t pts = av_rescale_q(ts, av_time_base_q, m_VideoStream->time_base);
                if(m_video_pts >= pts){
                        printf("!!!!!!v!!!!!!!imposible, pts(%lld) > pts(%lld)\n", m_video_pts, pts);
                        return 0;
                }
                if(m_audio_pts > pts){
//                        printf("!!!!!maybe!!!!!imposible, apts(%lld) > pts(%lld)\n", m_audio_pts, pts);
                }
                m_video_pts = pts;

                AVPacket pkt;
                av_init_packet(&pkt);
                pkt.pts = pts;
                pkt.dts = pts;
                if(frametype){
                        pkt.flags |= AV_PKT_FLAG_KEY;
                }
                pkt.stream_index = m_VideoStream->index;
                pkt.data = (uint8_t *)pBuffer;
                pkt.size = iBufSize;

               
                //printf("get[%d] : %d\n",pkt.stream_index,m_FormatContext->streams[pkt.stream_index]->codec->codec_id);

                return av_interleaved_write_frame(m_FormatContext, &pkt);
               
        }

av_interleaved_write_frame这里面报的错误

你好，你的在linux 怎嘛变异的，我的总是编译不通过。支持h264 在·arm 交叉编译
