EVA Q BDMV原盘
avs内容如下：（事先已经创建好index文件）
FFVideoSource("00002.m2ts", cachefile="00002.m2ts.ffindex").Crop(0,132,0,-132)
压制命令如下：
FFMPEG -i "00002.m2ts.avs" -f yuv4mpegpipe -an -v 0 - | X264 --profile high10 --preset veryslow --tune animation --crf 16 --demuxer y4m -o "00002.m2ts.264" -
声音部分我是用tsMuxeR_2.6.12直接Demux，然后flac压缩
最后用mmg直接合并
合并完之后发现画音严重不同步，声音比画面快0.5秒左右。。。
然后LZ给源文件跟压制后的文件都挂上FFVideoSource/AVS，随机抽取几帧来检查，发现问题有点复杂
有些相差11帧，有些相差12帧，有些相差13帧，这是什么情况？明显不太科学啊，MPC自身问题？

FFVideoSource并不适合作为m2ts的源滤镜
你可以试试FFVideoSource(xxxxxx, threads=1, seekmode=-1)

FFVideoSource读m2ts会出现seek不准确。建议使用LWLibavVideoSource或者DGNV

Decoding some M2TS files using Haali's splitter will cause massive blocking and other corruption issues. You can work around the issue either by remuxing the file to MKV (using GDSMux (make sure you untick "minimize output file size" in the Global settings tab) or eac3to), or (if you will be doing linear decoding only) by setting demuxer="lavf" in FFIndex and using seekmode=0 with FFVideoSource. The cause of this issue is unknown but being investigated.
