• • 将问题标记为过时，因为使用了过时的**avcodec_decode_video2

我目前在使用ffmpegs api解码视频时遇到了伪像。在我假设为中间帧的帧上，伪像只会从帧中的活动移动缓慢地构建。这些伪像会构建50 - 100帧，直到我假设一个关键帧重置它们。然后帧被正确解码，伪像继续构建。
有一件事困扰着我，我有几个视频样本是30fps（H264）的工作正常，但我所有的60fps视频（H264）经验的问题。
我目前没有足够的声誉来发布图像，所以希望这个链接将工作. http://i.imgur.com/PPXXkJc.jpg

我尝试建立一个解码帧队列，然后使用并根据需要释放。我的帧分离是否会导致中间帧解码不正确？我还打破了解码循环，一旦我成功地收集了一个帧（解码：：成功，我见过的大多数例子往往循环通过整个视频。
所有编解码器内容、视频流信息和格式上下文的设置完全如https://github.com/chelyaev/ffmpeg-tutorial/blob/master/tutorial01.c的main函数所示
