How to fix scan­ner pro­blem on Ubuntu 18.04 with HP La­serJet Pro MFP M125nw prin­ter

Af­ter do­ing a clean in­stall of Ubuntu 18.04 in May 2018 and in­stal­ling HPLIP soft­ware to be able to print on my Hewlet Pac­kard La­serJet Pro MFP M125nw prin­ter, prin­ting wor­ked correctly. Then it got bro­ken by causes unk­nown to me in June and I had to fix it. This, however, didn’t go wi­thout com­pli­cati­ons.

Exctract blue-ray vi­deo stre­ams from ISO file un­der Li­nux (Ubuntu)

To be able to en­code blue-ray (BD) source into some more uni­ver­sal for­mat, you have to first have ac­cess to sin­gle video/audio stre­ams that com­prise the BD. These are vi­deo fi­les with ex­tension .m2ts in­side which is an Advan­ced Vi­deo Co­dec (High@L4.1) vi­deo and PCM au­dio. For now, this ar­ticle will skip the sub­tit­les be­cause I currently don’t have a BD with sub­tit­les on my disk. These fi­les are nor­mally pla­ya­ble in a pla­yer like MPV.

How to start with transco­ding aka fai­rly sim­ple long ge­ne­ral transco­ding gu­ide

In­tro­duction

So, again a transco­ding (en­co­ding – si­mi­liar terms) gu­ide, this time ge­ne­ral and in En­g­lish. This one should serve as an equi­va­lent for the Czech one i wrote some time ago (al­though much newer and up-to-date).

MS Word 2007: En­ter com­ment, en­ter note un­der line, etc. gra­yed out

Have ever hap­pe­ned to you that you were sent a do­cu­ment (.doc) from so­me­body using Ope­nO­f­fice and you couldn’t add any com­ments and no­tes and stuff? Well, it hap­pe­ned to me some while ago and it took me a while to get it sol­ved. It lo­oks like some com­plex pro­blem but it’s actu­ally very stu­pid. At le­ast, I felt stu­pid when I found out what is it about.

Blu­ray en­co­ding

A word of in­tro­duction

It’s now about 8 mon­ths since I star­ted my „en­co­der ca­reer“ in a group rip­ping anime DVDs known as Ani­me­corpx (ACX). I work for them as an en­co­der and what we do is ba­si­cally rip­ping anime DVDs re­le­a­sed in the USA to make them ac­ces­si­ble for the rest of the world, where you can’t buy them. But I actu­ally hate DVDs. They have low qua­lity vi­deo, cle­a­ning their image up is pain and they ge­ne­rally suck. It came out I’m not the only one in ACX who ha­tes low res and that shitty image of DVDs. It was shitsu, my Swiss colle­a­gue, who actu­ally made me think about an op­tion, that I could en­code BDs and that it mi­ght not be as im­possi­ble as I thou­ght it is. As I star­ted some re­search on this to­pic, I found out, that it’s not di­f­ficult at all. However, it requi­res so­mewhat di­f­fe­rent ap­pro­ach and di­f­fe­rent tools, so it took me a while to get into it and I re­lied on other gu­i­des and blog po­sts scat­ter on mul­tiple pages. That’s why I de­ci­ded I should write so­me­thing sim­ple to follow about en­co­ding BDs.

Note that this text as­su­mes some le­vel of knowledge about en­co­ding.

Mul­ti­lan­gu­age blog po­sts – Po­ly­lang

I re­cently de­ci­ded, that I want to write a ce­train gu­ide (which will ho­pe­fully ap­pear here soon), and I want it to be in more lan­gu­ages (pre­ci­sely in Czech and En­g­lish). So I star­ted some re­search on this to­pic, but it was tou­gher than I ex­pec­ted, be­cause I didn’t re­ally know what to search for. Tes­ting va­ri­ous ways of achie­ving my goal inclu­ded up­da­ting to WP 3.3 which I fea­red pretty much cause of my bad ex­pe­ri­ence with one WP up­date some time ago, but this one tur­ned out all right, though. Then I found a plu­gin called Po­ly­lang.
