"seek" in plugins- Which formats/codecs to use?

[alexsott2]

Hi,

Which file formats/codecs support an arbitrary seek in plugins? For example, skipping to the pre-defined point in the file by using JS.

I tried a bunch of files, on some of them "seek", or jumping to the predefined time position works just fine, on others it is just ignored and VLC keep playing the content.

Please advice what is the requirements for file format and codecs to make "seekable" video files.

Thanks
