解决方案：avcodec_receive_packet AVERROR(EAGAIN)在使用FFmpeg进行音视频编解码时，我们经常会遇到各种错误和异常情况。...其中，一个常见的错误是avcodec_receive_packet返回AVERROR(EAGAIN)。本篇博客将围绕这个错误展开讨论，并提供解决方案。...然而，有时候这个函数会返回AVERROR(EAGAIN)错误，导致我们无法获取到数据包。错误原因AVERROR(EAGAIN)表示再试一次。这个错误通常出现在数据包的缓冲区中没有可用的数据包时。...解决方案要解决avcodec_receive_packet返回AVERROR(EAGAIN)错误，我们可以采取以下策略：在收到AVERROR(EAGAIN)错误后，继续调用avcodec_receive_packet...总结： avcodec_receive_packet返回AVERROR(EAGAIN)可能是因为解码器内部缓冲区没有可用的数据包。
