Yeimwe shanduko dzinomira yeiyi vhezheni itsva:

• Iyo nyowani yepamusoro-soro API, GstTranscoder, yakataurwa iyo inogona kushandiswa mukushandisa kushandura mafaira kubva kune imwe fomati kuenda kune imwe.
• Yakawedzera rutsigiro rweiyo AFD (Inoshanda Fomati Tsananguro) uye Bar Dhata codec yakaiswa.
• Iyo qmlgloverlay element yakawedzerwa kubvumira iyo Qt Kurumidza chiitiko kuti chiwoneke pamusoro peinouya vhidhiyo kuyerera.
• Icho chifananidzo chekushurerc chakawedzerwa kuti zvive nyore kugadzirwa kwekuteedzana kwevhidhiyo kubva mukuteedzana kweJPEG kana PNG mifananidzo.

• Wakawedzera vaapioverlay element kunyora uchishandisa VA-API.
• Iyo splitmuxsink uye splitmuxsrc zvinhu izvozvi zvinotsigira zvinobatsira (AUX) vhidhiyo hova.
• Zvinhu zvitsva zvakaunzwa kugamuchira uye kugadzira RTP hova uchishandisa iyo "rtp: //" URI.
• Yakawedzera rpicamsrc element yekutora kamera vhidhiyo yeRaspberry Pi bhodhi.
• Yakagadziriswa ruzivo mharidzo uye vhidhiyo kugadzirisa neHigh Dynamic Range (HDR).

Finalmente kana iwe uchida kuziva zvakawanda nezvazvo nezve iyi nyowani vhezheni yeGstreamer unogona kutarisa iyo changelog Mune inotevera chinongedzo.
