Hi,

Could someone give me any hints to deal with AVCHD (*.MTS) files with free software?

I've tried mplayer (MPlayer SVN-r37150-4.8.3) with no result.
ffmpeg (version 2.1.5) seems go better: it'a problem on my hw resource, also, I think \
(Athlon 64X2@2.7Ghz, with 4GB RAM).


And these files are on some DVD UDF that are damaged, too.
GNU ddrescue (v.1.17) is a excellent tool for recovering a disk image, then I'd carve \
it with foremost.  Foremost (version 1.5.7) is also a excellent tool, but needs \
instructions on what types of file are to be found. File (v.5.19) enigmatically say \
that *.MTS files are "data".

With a little research on the net I cannot found the signature (magic number) for \
these files: it's depends on copyright reason?

I've tried also empirically with hexdump and strings on the head of some valid MTS \
file, looking for it. Then on the basis of some MTS file head comparison I've write \
these lines on my foremost.conf # euristic AVCHD MTS from head confontation:
    MTS    y    2000000000 \x00 \x00 \xb0 \x11 \x00 \x00 \xc1 \x00 \x00 \x00 \x00 \
\xe0 \x1f \x00 \x01 \xe1 \x00 \x23 \x5a \xab \x82 

Is this a reliable test?

Thanks,
 enrico
