how to open mpeg2 video files in avisynth without the ffms2 plugin?

[marcorocchini]

Hi cats

please I wonder if exist a way to open a .mxf mpeg2-Iframe video file, or .mpg but alwais mpeg2 video file
without the ffmpeg plugin (ffms2.dll) or dgdecode

What are other plugins to demux/decode mpeg2 video files?

Thanks

Probably l-smash , it can do most things ffms2 can

Last resort is directshow, because of the potential problems and frame accuracy.

mmm l-smash is interesting and seems frame accurate than ffmpeg

please consider my usual .mxf video source:

https://www.dropbox.com/s/ioy79qrqvfo0pss/C0020.mxf?dl=0

I have installed avisynth 2.6.0 and lsmash R729 with libav (L-SMASH-Works-r729-20141117-32bit-Libav.7Z)

but crash:



but if I convert the .mxf in .mov

ffmpeg -i C0020.MXF -vcodec copy -an C0020.mov

and try to open the .mov this error happen:



so I try to replace the LSMASHSource.dll with another version (I don remeber is is a older version or not)

I have try with this:

https://www.dropbox.com/s/zc2sri25g3qtkz8/LSMASHSource.dll?dl=0

(I have put it on the avisynth/plugins directory)

and opening the .mov is OK



but lsmash won't opens in all cases the .mxf

I wonder: is there a way to open the directly the .mxf with l-smash? thanks

Never heard of a .mxf until this post. You could also just mux the contents of the .mxf into an .mkv instead of a .mov. I tend to get better l-smash indexing when I put the video and audio into an .mkv. Whatever works for you.
