No probs, good luck for tomorrow.

Mark_Greaves_PCNetSp · 4 June 2014 22:06

Just noticed … SeZo has made exactly 1337 posts to date

SeZo · 4 June 2014 22:16

You lost me there. Why is 1337 significant? :-
OK, now it is 1338

Kiddie “hacker” term for “elite”.

I guess you’re now a “leeb” :-/

OK I tried your suggestions , mplayer would play the sound but no video just the same as VLC, running the other commands you posted made no difference

The good news is that the fixed files will play in avidemux albeit heavily pixilated and sound out of sync 
I tried to upload a sample to videobin which transcodes to ogg vorbis but it too only played the sound

If you think it would be easier I could send you a sample video to let you work on it directly but if you think it would be better to keep doing it this way that's fine :)


Many thanks

Just drop the sample video somewhere and then pm me the link.

[EDIT]
Looks like we are getting somewhere.
I had to download the earlier version of untrunc from here and used the already compiled untrunc executive from the extracted file.
run it with:

./untrunc ref1.mp4 004.mp4

This produced the video but only the sound was playable.
First tried avidemux:

avidemux --rebuild-index  --force-alt-h264 --load 004.mp4_fixed.mp4 --save "video.avi" --output-format AVI --quit

This produced a good quality playable video (sound is way out of sync)
Then tried ffmpg (sent you the link)

ffmpeg -i 004.mp4_fixed.mp4 -acodec copy -vcodec libx264 -s 722x406 -r 25 004-fixed.mp4

which produced similar result to the previous try (slightly smaller file size) unfortunately the audio is still out of sync.
See if you can reproduce that.

Ok I’ve downloaded the untrunc v1.0 .tar file as per your link to my Downloads folder nut I’m not really sure what you mean by this bit

and used the already compiled untrunc executive from the extracted file.

I managed to identify all the fixed.mp4 files I have by listening to the sound tracks and the videos I’m after ( 2 that I can think of) are not there so I suspect they’re among a load of .mov files (83 in total)

I tried fixing them using this format

./untrunc /home/graeme/movref.mov /home/graeme/Corrupted/mov/mov084.mov

but although it produced fixed files they wouldn’t play audio or video so i have no way to identify them.

I had a look at the Blondie video you worked on and the result is spot on other than the sound sync, the sound is too far advanced by approximately 2.5 secs and although I was able to correct that at the beginning of the video it seemed to run out again as the video progressed but I’m not 100% sure of that, I find adjusting audio sync gets more difficult the closer you get to it being right if that makes any sense.

Anyway thanks so much for your help I really appreciate it

If you look in ~/Downloads/untrunc_1.0/ there should be a file named untrunc which is an executable. I used that on mine.
You should test the corrupt files first with ffmpeg:
ffmpeg -i <filename>
If you get this line: [mov,mp4,m4a,3gp,3g2,mj2 @ 0x9ada840] moov atom not found then run untrunc on it, otherwise you will need to find different method to repair the file.

Ok that’s clear and understood, I’ll try your suggestions tonight when I get home

Many thanks

Hi again

I’m working on the .mov files here’s the output of a sample file using ffmpeg

graeme@Linux1 ~ $ cd /home/graeme/Corrupted/mov
graeme@Linux1 ~/Corrupted/mov $ ffmpeg -i mov000.mov

I tried to run untrunc on all the .mov files I have and although it placed fixed files in the folder none of them produced any audio or video

I tried to open the untrunc v1.0 executable and I can’t get it to open, if I click on “Execute” nothing happens and if I click “Execute in Terminal” the terminal flashes up for a second then disappears.

Many thanks

Graeme

I tried to open the untrunc v1.0 executable and I can't get it to open, if I click on "Execute" nothing happens and if I click "Execute in Terminal" the terminal flashes up for a second then disappears.

I just copied the untrunc executable to the folder where the clips reside. Then opened the terminal in that folder and run like this;

./untrunc ref.mp4 corrupt.mp4

I’m obviously doing this wrong I’m sorry :-[

Did you copy ~/Downloads/untrunc_1.0/untrunc to /home/graeme/Corrupted/mov ?
If not then do it like this:

cp ~/Downloads/untrunc_1.0/untrunc /home/graeme/Corrupted/mov

then cd in (just in case)

cd /home/graeme/Corrupted/mov

then run

./untrunc movref.mov mov000.mov

Mark_Greaves_PCNetSp · 6 June 2014 20:32

If it mentions ELF, isn’t that usually an error you see when trying to run a 64bit executable on a 32bit system … or vice-versa ?

Graeme

SeZo · 6 June 2014 20:48

Mark might be right, it worked on my 64bit system.

The bottom 3 lines are commented out. So not relevant.
Source code is usually neutral, you compile against the target (32 bit or 64)

Perhaps better to compile that from the source.

cd ~/Downloads/untrunc_1.0/

then

g++ -o untrunc file.cpp main.cpp track.cpp atom.cpp mp4.cpp -L/usr/local/lib -lavformat -lavcodec -lavutil

See if that version fares any better
