still no mxf?

[pantau]

i'm trying to find a way to get avisynth to work directly with avid mxf files. is there still no import plugin around? thanks!

[TheFluff]

ffvideosource should be able to open mxf. There's also this (http://code.google.com/p/dcinematools/wiki/MXFSource) that may or may not work better (I just googled "avisynth mxf" to find it; perhaps you should have done the same before posting this thread?).

[pantau]

thanks for your answer... it's not working for me, but maybe i'm doing something wrong...

i use megui, and ffms is part of it, so my script reads:

LoadPlugin("C:\Program Files (x86)\MeGUI 0.3.5\tools\ffms\ffms2.dll")
FFVideoSource("E:\Avid MediaFiles\MXF\1\ecohhh3AA01.4F395DB7.E24FF0")

the error i encounter is "FFVideoSource: Can't open ..."

am i maybe not loading the plugin the right way?

[poisondeathray]

maybe you mistyped the filename?



FFVideoSource("E:\Avid MediaFiles\MXF\1\ecohhh3AA01.4F395DB7.E24FF0")



E24FF0 doesn't look like an .mxf extension ?

[pantau]

thanks, you're right of course, i forgot the .mxf ending...

but now the error i get is: "no video track found"

[poisondeathray]

What kind of mxf file, what compression ?

Use mediainfo if you don't know

[pantau]

they are native HDV files

[poisondeathray]

xdcam or mpeg2 in mxf opens fine with ffvideosource, so hdv should too as well - maybe something peculiar about your particular files ?

you can try re-wrapping with ffmpeg into a transport stream first

[pantau]

how would i do that? could you give me a hint on how the ffmpeg command line would look to get a transport stream output?

[poisondeathray]

ffmpeg -i input.mxf -vcodec copy -acodec copy -f mpegts output.m2ts

or you can just demux it to m2v and use dgindex (hdv is just mpeg2)

[pantau]

sorry for my ignorance, do i have to specify to vcodec and acodec? running the script like this i get a "-vcodec: no such file or directory" error.

"C:\Program Files\ffmpeg-git-a923b6b-win64-static\bin\ffmpeg.exe" -i -vcodec copy -acodec copy -f mpegts "E:\EcoHHH\output.m2ts"

you didn't specify the input file; it's blank after the -i


-i inputfile.mxf

[pantau]

i see... now it works, but the output is zero bytes:

Input #0, mxf, from 'E:\Avid MediaFiles\MXF\1\ecohhh3AA01.4F395DB7.E24FF0.mxf':
Duration: 00:30:01.36, start: 0.433771, bitrate: 770 kb/s
Stream #0:0: Data: none
Output #0, mpegts, to 'E:\EcoHHH\output.m2ts':
Output file #0 does not contain any stream

[TheFluff]

Judging by that output it looks like the file is encrypted. ffmpeg detects a track, but can't detect its type (audio/video) or compression method. Since ffvideosource is based on ffmpeg, it gets the same result and you get the error "no video track found".

[pantau]

so demuxing to m2v wouldn't work either?

[TheFluff]

so demuxing to m2v wouldn't work either?

I guess that depends on what you use for that task. Try it and see if it works?

[TheFluff]

I guess the problem could also just be a bug in ffmpeg, I can't really tell. If you upload a sample file I guess I could take a look.

[pantau]

could you help me how to demux that with ffmpeg? in the documentation there is no mpeg demuxer...

unfortunately i also lack the knowledge to work with http://code.google.com/p/dcinematools/ (no idea on how to compile that)

the smallest file i have is 27MB; if i separate it it won't probably be the same. i'll send a yousendit link to it as soon as it is uploaded...

[TheFluff]

The dcinematools package only supports jpeg2k compression.

What gave you the impression that ffmpeg would support demuxing the stream when it can't read it?

[pantau]

I guess that depends on what you use for that task. Try it and see if it works?

i guess i misunderstood your remark. so what else could i use to demux?

here's the link of a short piece of mxf video:

[poisondeathray]

you can try ffmbc, it seems to handle mxf (and transport streams) better than ffmpeg

there is a free tool called amberfin mxf desktop that can demux mxf ; there might be some free mxf tools on sourceforge as well

edit: I didn't see you posted a sample

yes, amberfin works, it will demux a raw file, but you can safely rename the extension to .m2v, or just use dgindex on the raw file (it's just elementary mpeg2 video). There seems to be no audio in the sample .mxf ?

[pantau]

no, the audio is in separate files.

i'll try amber later...

[pantau]

do you have a source for amberfin apart from the company site which obliges you to sign up to news?

[pantau]

ffmbc is not available for windows is this right?

[poisondeathray]

I'll put a mirror below

Mods: It's free software, but requires a sign up. If this is violating any rules, I'll take it down

yes it is, you can compile for windows, but still has problems with your sample

[pantau]

thanks for the link... i can install it, but it crashes media player and vlc when i try to play a file.

anyway, i don't understand how it could help me to get the mxf-files into avisynth?

you demux to elementary video (i.e. video without mxf wrapper)

avisynth can open .m2v video (e.g. dgindex or ffvideosource)

[pantau]

it works, thanks... not really practical, as i have to demux the files one by one. hopefully some day in the future ffvideosource will work directly with mxf files.

VideoHelp (http://www.videohelp.com/tools/ffmbc) also has Windows builds of ffmbc

[pantau]

thanks... i can't find a description of parameters, neither on the videohelp nor the developers site...

[Brazil2]

ffmbc -h

or
ffmbc -h > ffmbc.txt
to print it all into a text file.

[pantau]

wow, i've never seen so many parameters... could you maybe help me with a simple command line?

is there a input filter based on ffmbc that would allow to directly ingest .mxf into avisynth? or would i have to unwrap/demux?

[poisondeathray]

I stated above, ffmbc doesn't work on your particular test file

The commandline would be basically the same as ffmpeg (just change ffmbc for ffmpeg)

(But it works for other mxf files, including mpeg2)

[pantau]

ok, so i'll give up for the moment... my test file is a standard avid hdv mxf file.

[poisondeathray]

other 'standard' avid files work, like dnxhd
