h264打包成flv，播放的时候开头总是会有一小段是绿屏的

[sinuos]

h264文件是采集摄像头后实时编码产生的，h264直接播放是好的，打包成flv，播放的时候开头总是会有一小段是绿屏的，ffplay播放的时候出现如下错误
[h264 @ 0x7f1718000d60] Cannot use next picture in error concealment

这是什么原因导致的

楼主，能分享您的H264打包FLV的源代码吗？？？我的邮箱[e-mail]

[garefield]

有b帧? if (s->next_pic.f) { if (s->next_pic.f->width != s->cur_pic.f->width || s->next_pic.f->height != s->cur_pic.f->height || s->next_pic.f->format != s->cur_pic.f->format) { av_log(s->avctx, AV_LOG_WARNING, "Cannot use next picture in error concealment\n"); memset(&s->next_pic, 0, sizeof(s->next_pic)); } } ffmpeg源码中是这么判断的,查查转码时的参数设置

楼主，这个绿屛，解决了吗，是什么原因啊，我也遇到这个问题了？

[smilestone322]

是不是H264数据没有从sps开始

[朱韦刚]

绿色是没数据。

请问楼主是这么解决这个问题的，碰到了同样的问题。
