关于编译android ijkplayer遇到的问题

作者: 浅吟且行的时光 | 来源:发表于2019-03-01 10:19 被阅读3次

    1. 执行./init-android.sh git拉取出错

    
error: RPC failed; curl 18 transfer closed with outstanding read data remaining 
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed```

----- 解决方法 -----
配置git缓冲区大小，命令行输入：git config --global http.postBuffer 2124288000
查看设置参数输入：git config --list

    2.执行./init-android.sh遇到的问题

    error: RPC failed; curl 56 SSLRead() return error -9806.42 MiB/s     
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: index-pack failed
error: Could not fetch origin

    ----- 解决方法 -----
    安装命令行输入：ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

    3.执行./compile-ffmpeg.sh all出错

    IJK_NDK_REL=19.0.4442982
You need the NDKr10e or later

    ----- 解决方法 -----
    使用的ndk版本过高，使用低版本的

    4.支持rtsp协议

    • 修改module-lite.s 件 录:~/config/module-lite.sh 将这 :
    export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --disable-protocol=rtp"

    替换为：

    export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-protocol=rtp"
    • 接着在下面添加上:
      export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-
  demuxer=rtsp"
  export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-
  protocol=tcp"
  export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-
  decoder=mjpeg"
  export COMMON_FF_CFG_FLAGS="$COMMON_FF_CFG_FLAGS --enable-
  demuxer=mjpeg"

    5. 解决延时大问题（优化后延时400毫秒左右）

    • ~/ijkmedia/ijkplayer/ff_ffplay.c文件中 将这一方法:
    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; }

    替换为：

    static int packet_queue_get_or_buffering(FFPlayer *ffp, PacketQueue
*q, AVPacket *pkt, int *serial, int *finished){
if (!ffp->packet_buffering)
return packet_queue_get(q, pkt, 1, serial);
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 (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; }
    • ~/ijkmedia/ijkplayer/ff_ffplay.c```文件中 修改这一方法为:
    static double vp_duration(VideoState *is, Frame *vp, Frame *nextvp) {
    //注释的源代码
    /*if (vp->serial == nextvp->serial) {
        double duration = nextvp->pts - vp->pts;
        if (isnan(duration) || duration <= 0 || duration > is->max_frame_duration)
            return vp->duration;
        else
            return duration;
    } else {
        return 0.0;
    }*/
    //新增代码
    return vp->duration;
}
    • ~/ijkmedia/ijkplayer/ff_ffplay.c```文件中 修改这一方法为:
    static int ffplay_video_thread(void *arg)
{
    FFPlayer *ffp = arg;
    VideoState *is = ffp->is;
    AVFrame *frame = av_frame_alloc();
    double pts;
    double duration;
    int ret;

    int64_t dst_pts = -1;
    int64_t last_dst_pts = -1;
    int retry_convert_image = 0;
    int convert_frame_count = 0;

    enum AVPixelFormat last_format = -2;
    int last_serial = -1;
    int last_vfilter_idx = 0;
    if (!graph) {
        av_frame_free(&frame);
        return AVERROR(ENOMEM);
    }

#else
    ffp_notify_msg2(ffp, FFP_MSG_VIDEO_ROTATION_CHANGED, ffp_get_video_rotate_degrees(ffp));
#endif

    if (!frame) {
#if CONFIG_AVFILTER
        avfilter_graph_free(&graph);
#endif
        return AVERROR(ENOMEM);
    }

    for (;;) {
        ret = get_video_frame(ffp, frame);
        if (ret < 0)
            goto the_end;
        if (!ret)
            continue;

                av_frame_unref(frame);
                continue;
            }

            last_dst_pts = dst_pts;

            if (dst_pts < 0) {
                dst_pts = ffp->get_img_info->start_time;

            }

            pts = (frame->pts == AV_NOPTS_VALUE) ? NAN : frame->pts * av_q2d(tb);
            pts = pts * 1000;
            if (pts >= dst_pts) {
                while (retry_convert_image <= MAX_RETRY_CONVERT_IMAGE) {
                    ret = convert_image(ffp, frame, (int64_t)pts, frame->width, frame->height);
                    if (!ret) {
                        convert_frame_count++;
                        break;
                    }

                retry_convert_image = 0;

    • 编译后的Demo工程中setOption
    ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "packet-buffering", 0);
ijkMediaPlayer.setOption(IjkMediaPlayer.OPT_CATEGORY_PLAYER, "infbuf", 0);

    6. 执行./init-android.sh git拉取源码慢,几kb/s

    • 修改host文件，添加：
