I can cover Hungary. First of all, here's a recent interview with the authors of the book Sex and Socialism http://www.origo.hu/kultura/kotve-fuzve/20160414-szex-es-szocializmus-interju-kadar-rendszer-toth-eszter-zsofia-murai-andras.html:
Forgattak Magyarországon szexfilmet az előző rendszerben?
Nem tudunk róla, hogy forgattak volna, inkább csak erotikus fényképekről meséltek. Pest környékén 1968 után voltak értelmiségi kommunák, de nem hiszem, hogy itt filmet forgattak volna. Terjeszteni sem merték volna.
Did they shoot any sex movies in the socialist era?
As far as we know, no. We heard some tales about erotic photos. There were some communes around Pest after 1968 but I seriously doubt they shot any movies there. They wouldn't have dared to distribute it anyways.
So that's that.
But there's more. Film stock was near impossible to get. Something like the famous Zaprauder movie where anyone could just stand on the street and shoot things were absolutely impossible, you couldn't get a camera and more importantly, film negative was in very short supply. Check this interview http://comment.blog.hu/2008/11/16/sorozatklasszikusok_masfelmillio_lepes_magyarorszagon about how the classic One And A Half Million Steps In Hungary series came to be in 1977:
Ő akkor az Ismeretterjesztő Főszerkesztőségen dolgozott, én pedig az Ifjúsági Osztályon [...] a forgatáshoz 16 ezer méter színes negatív filmet kértünk, ami akkoriban a legdrágább volt, és az egész főszerkesztőségnek nem volt ennyi az éves keret
He used to work at the Education Department and I've worked at the Youth Department [...] and we asked 16 000 metres of color negative film and [in 1977] this was the most expensive and the whole department didn't have that much yearly quota.
Later the interview mentions one minute required 10 metres of film stock ("A kicsiben csak 30 méter anyag ment, tehát csak hárompercnyi anyag" -- "the little [camera] only had a 30 meter long [material] aka three minutes worth") which means the entire Youth Department of Hungarian state television had less than 26 hours worth of film stock allocated for an entire year!
As to pornography itself, check http://nol.hu/belfold/lenin-es-a-pucer-fenek-1475043 this article which details -- alas in Hungarian -- nakedness, sexuality in socialist Hungary, especially this part:
A televízióban a filmeken kívül Árkus József Parabola című műsorában „kínáltak” a férfi nézőknek meztelen nőket – pucér férfiakról szó sem lehetett.
The television "offered" naked women in some movies and Jozsef Arkus' Parabola but naked men were out of question.
And this was Hungary where the leadership tried to create at least the semblance of "modern" society. For example, in 1973 sexual education was added to the school curriculum and in 1978 a book with the title Open Marriages - Modern Lifestyle has appeared. But pornography was banned and the border guard have confiscated any and all pornographic materials they found (which of course led to the smuggling of pornographic magazines).
Hi! Not discouraging new contributions (although very much discouraging personal anecdotes, enthusiastic readers!), but this question has come up a few times, so you may be interested in previous answers
So... what was porn like in the Soviet Union? - featuring /u/facepoundr , /u/vertexoflife and /u/Georgy_K_Zhukov
What was the state of pornography in the Soviet Union? - featuring /u/Acritas
and a bit more here Was there pornography in Communist countries? If so, was it popular?

Check out this old AskHistorians thread which has some excellent discussion on the subject.
I'm not sure if this is close enough to be a related question, but in The Lives of Others the Stasi agent, Gerd, iirc, has access to some kind of official prostitution service for government employees. Did anything like this exist in these countries in the 80s?
The question doesn't specify if they mean film or print. There was a very interesting Soviet state sponsored fully explicit erotic alphabet by Sergey Merkurov in 1931 to promote adult literacy, examples of which can be seen below.
Additionally, just as bonus info, the question brings to mind a 1979 film titled "Librianna, Bitch of the Black Sea" that billed itself as "The first ever erotic adult motion picture ever filmed in Russia" which was a fully explicit adult film, though it was actually filmed in America by people using ridiculous accents.
