L-Smash: how usable are its binaries?

I have been trying to use the builds by 06_taro, but unfortunately

1) they seem to be very picky, and

2) their help screens and error messages remain very unhelpful

Code:
=>remuxer -i input.mp4 -o output.mp4
Error: failed to construct timeline.
Error: failed to get input movie.
Error: failed to parse command line options.
Code:
=>muxer -i input.m1v -o output.mp4
MP4 muxing mode
Error: failed to open input file.
Error: failed to open input files.
EDIT:

It would be interesting if someone took the time to "patch" mp4box with support for both DTS and VC-1

I can't help you with anything unless you show me what input files you try.

Anyway DTS-HD in MP4, and VC-1 in MP4 that starts without sequence header and entry point header can't play with the current libav/ffmpeg.
For DTS-HD: https://github.com/VFR-maniac/libav/...09f5a5d0.patch
For VC-1: http://patches.libav.org/patch/16191/

Edit: Now, both libav and ffmpeg includes the patch for VC-1.

Okay, I need some time for finding / creating / selecting / uploading the "killer samples" ,

BTW for the attention

As for the page:

http://up-cat.net/L%252DSMASH%2527s%2Brestrictions.html

it should clearly state, L-Smash does NOT support m1v nor m2v

( with or without an "acceptable" excuse )

P.S.: Besides,

why not combine "muxer" and "remuxer" into a single executable ?

At last...

vc-1-in-mp4.zip @

https://skydrive.live.com/?cid=5ACF0...0EBAE8D5%21126

The archive contains 8 files, 2 of which are VC-1 elementary streams generated by the !^#$%&#ly-named "avs2asf.exe"

* closed entry point = 0 * is accepted by L-Smash muxer

* closed entry point = 1 * is rejected by L-Smash :—/

filmleader01.mp4 was created thru muxer.exe ;
filmleader02.mp4 was created thru Zeranoe's build of ffmpeg ;

Besides:

In VirtualDub ++ the latest QuickTime plugin,

ffdshow (r4382) w/ wmv9 decoder shows only a sequence of black frames

ffdshow w/ libavcodec, && "easy" vc-1,
first frame = green

ffdshow w/ libavcodec, && "difficult" vc-1,
VirtualDub crashes

Hope this helps

I don't know.
If QuickTime plugin for VirtualDub is VfW based, then it might work incorrectly.
At least, that is not the problem of L-SMASH side.

You are right, I'd better link my next post on the ffdshow thread to this one

( again )

EDIT:

Just confirming, now muxer.exe is working as it should:

Code:

No.

AFAIK, there are no projects that use L-SMASH library except for what I manage (L-SMASH Works) and its forks, yet.

I continue to refactor the codes strongly so it is not recommended to use APIs currently, but you can use it for demuxing and muxing.
