Názory k článku AVI 2 DVD pod Linuxem

Pro jednoho znameho jsem jako 'proof of concept' stvoril v pythonu generator BMP titulkovych slajdu pro jeden Windowsovsky DVD software (chvastal jsem se, ze je to prace na 10 minut :)). Nevim o jaky sw slo, vim jenom, ze jako vstupni soubory pro tvorbu VobSubu byla sada BMP souboru s titulky a jednoduchy TXT soubor urcujici jejich cas. Mym vstupem byl .SUB format a kreslilo to i texty kurzivou (v .SUB tusim jako {Y:i}). Mozna bych to jeste nekde vyhrabal, pokud by to nekdo chtel (i kdyz to byl opravdu jen 10ti minutovy ugly hack :))

Zkuste Avidemux2, nahradi 2/3 clanku, protoze ovladani je intuitivni. Skriptovatelny je taky.

Casem jsem postup zautomatizoval, pouzivam to hlavne na vytvareni DVD z DV capture (Kino), a prilezitostne nahravky z TV DVB-T, od znamych:

Neviem ci tento clanok bude mat aj nejake pokracovanie, ale celkom pekny serial o tom ako si vytvorit DVD aj s menu je na http://www.abclinuxu.cz

Super clanek. Neznate neco jako avisynth pod Linux? Je to vinikajici nastroj a urcite mi v tomto systemu chybi. Avisynth-linux na sourceforge vypada mrtve...

No nevim. Vzhledem k tomu ze HW DVD prehravac nemam a DVD prehravam mplayerem, nevidim jediny duvod proc na DVD nepalit rovnou .avi. Usetri to spoustu mista.

Nacpat titulky natvrdo do obrazu je priserna prasarna, omluvitelna jen v pripade ze na stejny disk hodite zdrojove .avi i titulky, aby si to kdokoliv mohl pustit normalne alespon na pocitaci.

No prostě proto, že spousta lidí DVD přehrávač má a pak jaksi přehrávání videa na PC (větráky, malý monitor oproti TV) není to pravé ořechové :-).

Pekny postup ako z AVI na DVD. Skor by ma ale zaujimala nejaka odporucana modifikacia postupu/nastrojov na konverziu AVI -> SVCD. Existuje pod Linuxom nastroj na napalenie mpeg2(s vhodnym rozlisenim a fps) vo formate SVCD?

skript mencvcd s parametrom -svcdout vyrobi svcd-cko s hocicoho co prehrate mplayer-om, je sucastou mplayer-u, mozno treba stiahnut zdrojaky, alebo prebrowsit cvs tree

Ospravedlnujem sa za chybajuci Subj. v mojom predchadzajucom komentari.

Snad Vas to vsechny bude zajimat. STRANECKU KTERA POJEDNAVA O PREHOZENI DVD-ROM MECHANIKY VE STOLNIM DVD PREHRAVACI JSEM DAL NA http://www.bigosi.com/phprs/view.php?cisloclanku=2004031701

Protoze se mnozi dotazy proc neni dostupna stranka o PREHOZENI DVD-ROM MECHANIKY VE STOLNIM DVD PREHRAVACI DAL JSEM JI I NA http://www.aviatic.cz/phprs/view.php?cisloclanku=2004031701

V odstavci 3-5 autor píše: "nutno dodržet název "stream.yuv", je interně hardcoded v mplayeru" a navrhuje příkaz
   $ mplayer chickflick.avi
         -sub chickflick.sub
         -speed 25000/23976
         -autosync 30
         -benchmark
         -noframedrop
         -ao pcm
         -aofile audio.wav
         -vo yuv4mpeg
         -vop scale=720:576,expand=-1:-153:-1:-1
         -subpos 84 &

Právě jsem to zkoušel, ale nefungovalo mi to (MPlayer 1.0pre7-3.4.1). Jednak se podle dokumentace volba -ao používá trochu jinak, a jednak to vypadá, že jméno roury 'stream.yuv' není v mplayeru natvrdo. Mě fungoval příkaz
   $ mplayer chickflick.avi
         -sub chickflick.sub
         -speed 25000/23976
         -autosync 30
         -benchmark
         -noframedrop
         -ao pcm:file=audio.wav
         -vo yuv4mpeg:file=stream.yuv
         -vop scale=720:576,expand=-1:-153:-1:-1
         -subpos 84 &

Toť vše.

Starsi verze Mplayeru (0.9x) se chovaly opravdu viz. autoruv popis.
1.0-pre7 je novejsi generace, a chova se v nekterych aspektech jinak.
Princip ovsem zustava.

Přednastavené formáty jsou dva 8 a 9 co který znamená? v helpu jsem nenašel víc , než že je to DVD formát.

...od doby psani clanku prodelal vyvoj. Velmi pouzitelny software. Z postupu pouzivam hlavne authoringovou cast (viz. skript v komentarich/reakcich, kdesi vyse v tomto threadu).
