解决办法 #
根据作者的github上提交的代码描述
https://github.com/MediaArea/MediaInfoLib/commit/78f739893c85d4b1397276ef15badd160907b7aa
vim "Source/MediaInfo/Multiple/File_MpegTs.cpp"
void File_MpegTs::Streams_Accept()
{
...
if (!IsSub)
{
...
//TestContinuousFileNames();
...
}
}
我们只要将”TestContinuousFileNames();“这行注释掉即可解决默认获取ts文件序列问题
