These days, while according to neutral sources movies industry has never been so juicy so it made obviously necessary to restrict freedom in France in the name of its survival, I thought nice to share two small scripts handy when dealing with videos on your harddrive.
Surely, you wouldn’t store videos downloaded over the internet that you haven’t paid for. I guess that’s immoral since in 2009 the US box office top $10bn for the first time in history, during worldwide economic downfall . An advertisement paid by these guys that made these $10bn, while bankrupcy was really an option for major financial institutions and eviction just the same for poor tenants, said it is piracy – while it is still hard for me to envision how it relates to these events occuring on regular basis in Malaysia, Cameroon, Red Sea, etc.
And if you are not concerned by the moral issue (a communist like Jesus Christ, aren’t you?), maybe you are afraid to get caught anyway. Well, it is unlikely that police would come to your house with a search warrant looking for piracy evidence. Mostly because there is no such thing in French law as a search warrant. Indeed, police is entitled to enter in your house in some cases: in three cases only. First, there is what is named commission rogatoire, an order given to a policemen by a judge to do something specific in his name such as search in your house. Looks obviously like an US/UK common law search warrant but it is not: sure it gives the same rights to the police, but it is not an usual procedure in France as it applies only to criminal investigations (information judiciaire), not for trivial misdemeanour/regulatory offences. Second, in the case of a enquête de crime ou délit flagrant (felony or misdemeanour punishable by jail time that just occurred), police can enter your house without your consent. Three, in what is actually the only case that would allow police to enter your house for a regulatory offence (which what this piracy is actually more or less about) is the enquête préliminaire – funny, in this case, police requires your (written) consent to enter. If guess that if I had this kind of piracy evidence at home and the police coming to my doorstep asking to enter in an enquête préliminaire, I would probably not consent.
And I would not even dare to bring the issue of the fine endorsed by this HADOPI law. It is said that, as a friendly reminder of your place you should not have forgotten so easily (customer, yes, that’s you – nothing else – even if you do no harm, it is not up to you to proceed otherwise as you’d wish), by Law, your Internet access will be discarded while you’ll still pay for it. Well, French penal Law states also that “Nul n’est responsable que de son propre fait”, meaning that you can only be punished for your own doings. Sure, there are exceptions (boss that somehow forced employee to misbehave, etc). But none that I think of such as the case of two persons living in the same house and being punished together for the actions of only one of them without the knowledge and consent of the other. By principle, this idea is outlaw, a regression of two thousands years of penal law, dropping us back in the days when you were entitled to take possessions (by force if necessary) of the belongings of a spartian you’ve just met because, as athenian (or whatever), you were recently spoiled by another spartian, no matter that they had no ties aside their citizenship.
It could surely be tuned – I noticed issues when dealing with .mkv files. So far it uses mencoder (mplayer’s encoder) with lavc as audio codec and x264 as video codec. So obviously it requires mencoder, with support of these two (usual) codecs. It implies ffmpeg as well.
To use it, go in the directory where you have avi or mpg files, put the script in there and call it (it will always process all the files in the current `pwd`).
$ cd ~/myvideos
$ chmod +x dir2x264.sh # (if not made executable already)
It will log work being done in dir2x264log, to easily evaluate the harddisk space saved.
2. In case you cannot find (Have you tried SMPlayer?) the exact correct subtitle file for your video but found one that is just fine except there is a delay between the sound/image and the subtitle, the subtitle_reset.pl could do the trick for you. It depends on Subtitles.pm (libsubtitles-perl in debian).
This script takes two command line arguments: –file and –time (in seconds, positive value or negative), so the usage is quite obvious.
It will make a backup of the original file. If you run it several times to finely adjust your file, it will always restart from the backup file, unless removed obviously.
Note that however this script will not help if the matter is that the video and subtitles file frame-rate differs. You may want to give a try to subs, a script that is now shipped with Subtitles.pm (that was not there or that I missed when I first wrote this one).
July 31, 2010 Update: I thought I found a workaround the Matroska sound issue (Too many audio packets in the buffer). As mencoder is unable to properly convert them, after googling around, I gave a try to the idea of extracting apart the audio and video stream and to put them back together afterwards with mencoder. It actually now is able to produce a working mp4 file with the two streams but it seems that the audio is out of synch with the video. SMPlayer can correct the delay while running, though. So it is better than before but it is still buggy.
August 11, 2010 Update: I noticed several issues with mencoder-produced mp4. I modified the script to use only ffmpeg (except the mkv-specific part that I have not modified).
