Hi:

The first problem is "[mpeg4 @ ...] Invalid and inefficient vfw-avi packed B frames detected"
The second problem is "/torch/install/bin/luajit: bad argument #2 to '?' (start index out of bound at /tmp/luarocks_torch-scm-1-2915/torch7/generic/Tensor.c:984)"
I don't know how to fixed these problems...
And how to prepare the dataset,do I have to extract RGB and optical frames into jpg files from video?
hi, how do you configure your Video Decoder Library for Torch, when I configured it, it appears an error.
could you give me your configure steps? thank you.
Hi.this is my install step:
step1:download torch-toolbox into "~/torch/pkg/"
step2:cd video-decoder
step3:make
step4:make install
step5:install ffmpeg follow the normal steps
$ luarocks install ffmpeg
$ sudo add-apt-repository ppa:mc3man/trusty-media
$ sudo apt-get update
$ sudo apt-get dist-upgrade
$ sudo apt-get install ffmpeg

I found a mistake at line 525,
line 525: " table.sort(nameSubVideo) -- ascending order"
"nameSubVideo" have to be "nameSubVideoTemp"
Without changing,the program will stop at line 679.
thank you very much
when I run at step3, I met an error, did you meet before?
Yes,if I use lua 5.2,will get lots of errors.
But if I install torch without lua5.2(just use luaJIT)
It'll compile successfully.
ok, thank you, i will try it immediately
@Datasharing-wow
I also found the mistake at line 525,
"nameSubVideo" have to be "nameSubVideoTemp"
you are right!
thank you for share.
