PR描述:
ffmpeg 长时间推送rtmp音视频流，导致ffmpeg 报错av_interleaved_write_frame(): End of file，进而导致程序退出 error conversion failed。
详细描述:
原因:ffmpeg 通过av_interleaved_write_frame将音视频数据通过librtmp库函数RTMP_Write将数据发送到rtmp服务器。RTMP_Write内部会检查buffer数据大小，当size小于11时，RTMP_Write返回false，进而导致av_interleaved_write_frame函数返回AVERROR_EOF，该bug出现。
解决方法:当RTMP_Write返回false时，如果因为size太小的原因导致，不再返回AVERROR_EOF，继续运行，忽略该错误。至于什么原因导致的此次传输buffer size太小，暂不细究。
