Xiph.Org, mis on tuntud Daala, Opus, FLAC, Vorbis ja Speexi videode ja helikodekite arendajana, esitles uut vabakoodiga kodekit Theora 1.2, mis ilmus 15 ja poole aasta p\u00e4rast eelmist v\u00e4rskendust. Kodek on saadaval vabade litsentside alusel ilma litsentsitasude (royalty-free) kogumiseta. Theora videokompressiooniformaat kasutatakse tavaliselt koos Vorbis helikodekiga Ogg konteinerites ja saab t\u00f6\u00f6tada muutuva ja fikseeritud bitikiirusere\u017eiimides. Kodeerimise kvaliteedi poolest on Theora H.264 ja DiVX l\u00e4hedal. Kodeki viidatud rakendus on saadaval BSD litsentsi alusel. <\/p>\n

Uue v\u00e4ljaande ettevalmistamisel keskenduti eelk\u00f5ige j\u00f5udluse ja kodeerimise efektiivsuse t\u00f5stmisele. Bitivoogude (bitstream) tasemel vastab Theora 1.2 t\u00e4ielikult 2004. aastal standarditud Theora videokodeerimisformaatidele. Uue versiooni API ja ABI liidesed s\u00e4ilitavad t\u00e4ieliku \u00fchilduvuse eelmine Theora versioonidega. Theora 1.2 sisaldab 190-lehek\u00fcljelist spetsifikatsiooni, API dokumentatsiooni, RPT-laiendite spetsifikatsiooni mustandi voogedastuseks ning kodeerija ja dekodeerija viidatud rakendusi. <\/p>\n

Theora 1.2 peamine muudatus on uus viidatud kodeerija rakendus, koodnimega «Ptalarbvorm». Uues rakenduses on j\u00f5udlus oluliselt t\u00f5usnud ja saavutatud on k\u00f5rgem kompressioonitaseme. Uue kodeerija loodud failid on t\u00e4ielikult \u00fchilduvad eelnevate versioonide dekodeerijatena pakutud dekodeerijatega. <\/p>\n

Theora 1.2-s on ka optimeeritud viidatud dekodeerijat, lisatud tugi RISC OS platvormile ja oluliselt parendatud ARM arhitektuuri tuge. Lisatud on optimeerimised ARM CPU ja DSP TI C64x+ jaoks. Pakutud on kolm kodeerimiskiirusetaset (vana tase 2 on \u00fcmber nimetatud 3-ks, ja teise asemel on pakutud uus vahepealne tase).
