android ffmpeg错误致命信号11

我在Android上使用ffmpeg。并使用RTSP网络摄像头

我指的是

我有很好的视频

但我在结束视频时收到错误

螺纹2537（螺纹-13225）0x8a7c0d04（代码=1）处的致命信号11（SIGSEGV）

因此，我使用日志发现了错误。但我不知道为什么会发生错误

下面的代码是错误的位置

void closeMovie(){
  av_read_pause(gFormatCtx);
  if (gVideoBuffer != NULL) {
    free(gVideoBuffer);
    gVideoBuffer = NULL;
  }
  if (gFrame != NULL)
      av_free(gFrame);
  if (gFrameRGB != NULL)
      av_free(gFrameRGB);
  if (gVideoCodecCtx != NULL) {
      avcodec_close(gVideoCodecCtx);
      av_free(gVideoCodecCtx);
      gVideoCodecCtx = NULL;
  }
  if (gFormatCtx != NULL) {
      **av_close_input_file(gFormatCtx);** //here
      gFormatCtx = NULL;
  }
}

及

及

如果

//s->iformat->read\u close（s）不崩溃

但是我不能再打开视频了。再次打开视频，我必须退出应用程序

对不起，我英语说得不好。
谢谢你的阅读

ps2.日志的顺序

(BasicPlayer.c) closeMovie in->

谢谢你的阅读

我必须解决这个问题

添加代码utils.c

typedef struct {
    int audio_size;    /**< audio packet size (bytes) */
    int video_size;    /**< video packet size (bytes) */
    int palette_size;  /**< palette size (bytes) */
    int video_type;    /**< per-frame video compression type */
} JVFrame;
typedef struct {
     JVFrame *frames;
     enum {
         JV_AUDIO = 0,
         JV_VIDEO,
         JV_PADDING
     } state;
     int64_t pts;
} JVDemuxContext;

以及修改代码

void av_close_input_stream(AVFormatContext *s)
{
    flush_packet_queue(s);
    if (s->iformat->read_close)
       //**s->iformat->read_close(s);** //here fixed --> 
       read_close(s);
    avformat_free_context(s);
}

我不知道。为什么会产生错误

但通过修改代码解决了这个问题

void av_close_input_stream(AVFormatContext *s)
{
    flush_packet_queue(s);
    if (s->iformat->read_close)
       //**s->iformat->read_close(s);** //here fixed --> 
       read_close(s);
    avformat_free_context(s);
}

如果您有任何问题，我希望这会有所帮助

对不起，我英语说得不好。谢谢你的阅读

static int read_close(AVFormatContext *s)
{

    JVDemuxContext *jv = s->priv_data;
    av_free(jv->frames);
    return 0;
}

void av_close_input_stream(AVFormatContext *s)
{
    flush_packet_queue(s);
    if (s->iformat->read_close)
       //**s->iformat->read_close(s);** //here fixed --> 
       read_close(s);
    avformat_free_context(s);
}
