Hi, Oleg, thanks again for the support!
I tried the script with the mkv but no success. I am uploading a small
mkv (75MB) for you to see. I guess you are right: ffmpeg probably
change the headers.
With this file I'm uploading, the same cenario occurs: the php script
won't split it; ffmpeg does
Hello Flavio,
What are your source files? Did you record video on HDD or you streamed it over
the network and used other software for converting and recording?
Files recorded by the camera to the HDD have all the Exif fields, including
MakerNote, but I'm not sure if other programs preserve
Hi, Andrey,
I have recorded both in the HDD and the stream.
In this shot in particular, the hdd failed because we stood there 2 hours
under a 5000w light inside a room setting the scene - the hdd had no cooler
and eventually failed when the shot was made. I was able to mix two of
these shots so
No success here... =/
I uploaded two files to elphel's ftp (folder Videos). I used ffmpeg to
convert a mkv file to a series of jpegs. One of them is the jpg, the
other is just the jpg renamed to jp4. If I use elphel_dng to convert
them to dng, the colors shift completely. I can't seem to make
Flavio,
Looks like ffmpeg puts (at least) its own headers into the
files: JFIF Lavc52.123.0... - this causes the wrong conversion.
I don't know whether an *.mkv file has full frames inside (most likely it's
not)
If it does then
That's quite odd! That's exactly how it's supposed to look like, how did
you do that? I didn't know that you could actually use movie2dng for single
JP4 files! That changes everything!
This frame was from one of those 'broken' header mov sequences. I used your
php script to break it into JP4
Oleg, this made the trick! Thank you very much! =)
And thanks for modifying the script to work via command line, that was also
very helpful!
I left my house today and the footage was about 80% converted. Raise the
drums! =)

Btw, do you know what might be the cause of this header error? The cam

Flavio, I do not know what caused it - maybe by analyzing th footage you
Guys, yesterday we shot 90% of our movie, in heavy days in our location.
I notice at the moment that even though some files are here in the HDD
(some with 1GB, others with 500MB), they do not play in mplayer, and
do not convert with ffmpeg nor movie2dng. I would guess this may be a
problem with
VLC (and VirtualDub - only for windows though - also not sure if it can
handle quicktime files) have some header fixing routines that can often
rescue these kind of files.

Flavio,
Here http://community.elphel.com/files/php_scripts/ there's a file
split_mov.php (get it in an archive). You could try splitting one of the
MOVs to check if they have valid frames at least.

Flavio, maybe you can compress and upload one of the clips so we can
collectively try out methods to fix it?

You should be running it from a browser
Ok, one last try. I have Apache installed now and followed your steps
- copied the file to the folder. The /teste/ folder is writable by
everyone.
Now the browser tells me you selected to open split_mov.php. If I
download it, it downloads the script.
*I'm also uploading a 100mb sample to the ftp
oh, sorry, the first one was sort or 'readable' (with defect by
mplayer) so I decided to upload one that was completely non-readable,
sorry. but since that one ends, (it's bigger, 200mb), if you'd be so
kind to test it, i'd appreciate!!! =)

Ok,
1. You have apache installed right? In Ubuntu the www-root folder is at
/var/www - copy split_mov.php there,
2. Make /home/livre/Desktop/teste/ writable for everyone.
3. Then go:

Ok, you just don't have php enabled on the web server.
I see you have been uploading 2 files - one is already done ~21MB and
another one is still being uploaded. Shall I try the 1st one?

Looked at the file header - the MOV header is emtpy (all zeros), while the

Oleg, thank you very much! I'll definitely test it tomorrow
(currently, my comp is gasping with the bunch or raw frames). I
believe I can proceed from the jp4s using one of Carlos Padial scripts

I don't believe I had wb on, I always kill the autoexposure before
recording and I believe I turned
