iso版本，苹果5手机在播放m3u8的视频。播放一段时间后，会一直缓存中，导致视频无法继续播放。

[OCer]

我也出现了这个问题，不知道什么时候缓存结束

[andyjmzheng]

现在的场景是 如果在播放到视频快结束的时候。开始缓存。这样就会一直停留在缓存的状态开始：FFP_MSG_BUFFERING_START。没有来状态FFP_MSG_BUFFERING_END。 通过分析代码发现：要切换到FFP_MSG_BUFFERING_END需要满足下面的if 要保证音频和视频中的队列数据大于队列的总大小。并且音频和视频的队列中的nb_packet大小也要大于50000.如果快到文件尾缓存了。上边的俩个条件都达不到。所以就不会来FFP_MSG_BUFFERINGEND 消息了。 /* if the queue are full, no need to read more / if (ffp->infinite_buffer<1 && !is->seek_req &&

ifdef FFP_MERGE

          (is->audioq.size + is->videoq.size + is->subtitleq.size > MAX_QUEUE_SIZE

else

          (is->audioq.size + is->videoq.size > ffp->dcc.max_buffer_size

endif

        || (   stream_has_enough_packets(is->audio_st, is->audio_stream, &is->audioq, MIN_FRAMES)

            ))) {

endif

        if (!is->eof) {
            ffp_toggle_buffering(ffp, 0);
        }

@bbcallen

[andyjmzheng]

出现了 FFP_MSG_BUFFERING_START 这个后就一直缓存卡在哪里。不来 FFP_MSG_BUFFERING_END。 @bbcallen @Android4MediaPlayer

[andyjmzheng]

把MAX_QUEUE_SIZE 修改小了。非常容易出现缓存卡住的问题

[Android4MediaPlayer]

It works well.

[andyjmzheng]

我现在测试用的是ijkplayer最新版本的demo测试的。以前的0.4.4.1版本在ios也有此类问题。 @Android4MediaPlayer

[andyjmzheng]

android的手机测试没有问题。

[bbcallen]

Can't reproduce here. You can run git grep "Continuity check failed for pid" in ffmpeg's directory to see where it happens.

[albertcsg]

您好，我也是遇到了这个问题，卡在FFP_MSG_BUFFERING_START:不返回END，请问您是怎么解决的呀。@andyjmzheng

[Joe-xuzejia]

我也是 啊 ，有解决的办法吗？

[babyfish21]

同样的问题，有解决方案了吗？
