Removing audio streams with ffmpeg

I just found that WMP11 can’t select which audio stream is played from a DVB-S m2t (AVCHD) file. So I turned to Linux to figure out how to fix a Windows bug as usual! Turns out the fix is easy and takes about 1m20s: ffmpeg -i infile.m2t -acodec copy -vcodec copy -map 0:0 -map 0:4 outfile.m2t The 0:0 is the video track and 0:4 is the English audio track we want to keep; 0:1/2/3 are the voiceover audio and subtitle tracks we want to remove.

Its Like Dixons In Here

Now my server is finally back online (apparently although hosted in Germany somewhere, the support staff are in flood-ridden Australia) so I thought I’d update the blog. I’ve rebuilt my desktop machine now I’ve got the HDTV card. I finally fitted the 64Gb Kingston SSD boot drive, installed Fedora 14 and put the 1Tb SpinPoint F3 hard disk back in to supplement the rapidly-filling 1Tb F1. I noticed how much of a difference the SSD makes when rebuilding the Nessus plugin cache – on a HDD it takes literally minutes, on the SSD its almost instant!

Freesat HD recording

I’m thinking of getting a WinTV Nova HD-S2 card for my PC as there’s a satellite feed right by the computer in my bedroom – albeit with an aerial connector on it, so I’d need a female aerial to female F-type adaptor. I could watch/record Freesat HD in my bedroom and stream it over the new GigE to the Revo downstairs (which has hardware accelerated HD playback – currently using about 30% CPU watching 720p from BBC iPlayer) and also watch SD Sky using the box in the lounge.

Network wiring

I received my new Acer Aspire Revo R3610-M nettop which comes preloaded with Windows7. Plugged it in a wireless is pretty crap on it (could also be the BT Business Hub as I’m getting a stronger signal from nextdoor’s BE-box!) its good enough for surfing but not stable enough even for SD movies. I Installed Fedora14 and it didn’t even pick up the RT3090 wireless-N card, which is supposed to work with the RT2x00 drivers (awful drivers I’ve used before).

Gawker password cracking with JtR

I built some 64-Bit Fedora 13/14 RPM’s for John-The-Ripper 1.7.6 with the OpenMP-7 patch applied so I could use more than one core for cracking the Gawker list. Download here. I had to remove the Fedora-specific CFLAGS and edit params.h to force “#define JOHN_SYSTEMWIDE 1”, plus applying the single-have_words-fix-1 patch that is needed when not building with Jumbo-9. So I acquired the Gawker password list, which contains 1,247,893 usernames and passwords; however only 541,520 of those have email addresses too (which I expect will be seeing an increase in their spam soon!
