Inguqulo entsha ye-GStreamer 1.18.0 isivele ikhishiwe

Ngemuva konyaka nohhafu intuthuko, I-GStreamer 1.18 ikhishwe, iqoqo lezinto ezinqamulelayo ezibhalwe ku-C ukudala izinhlelo eziningi ezahlukahlukene, kusuka kubadlali be-multimedia kanye nabaguquli befayela lomsindo / ividiyo baye kuzinhlelo zeVoIP nezinhlelo zokusakaza.

Enguqulweni entsha i-API entsha yamafayela wokufaka amakhodi yethulwe kusuka kufomethi eyodwa kuya kwenye, kanye ne- ukuthuthukiswa kokusekelwa kwe-HDR, ukuxhaswa kokwandiswa I-RTP TWCC nezinye izinto eziningi.

Izici ezintsha eziyinhloko ze-GStreamer 1.18

Kule nguqulo entsha eveziwe Umsebenzi wenziwe ekuthuthukiseni ukwesekwa kweGstreamer futhi lokho singathola izengezo ezahlukahlukene kule nguqulo entsha 1.8, njenge-plugin ye-AVTP (I-Audio Video Transport Protocol) yokudluliswa kwevidiyo nomsindo okuzwelayo.

Kanye futhi nokusekelwa okusha kwephrofayili ye-TR-06-1 (RIST - Ezokuthembeka Zokusakaza Kwe-inthanethi), i ikhono lokushintsha isivinini sokudlala endizeni futhi usekela nokwandiswa kwe-RTP TWCC (Google All Transport Congestion Control) ku-rtpmanager.

Endabeni ye- Windows, lo ukusonjululwa kwamavidiyo okusheshisiwe kusetshenziswa i-DXVA2 / Direct3D11 APIkanye ne-plugin yokubamba ividiyo nokusheshisa ukufaka ikhodi usebenzisa iMicrosoft Media Foundation. Kungezwe ukusekelwa kwe-UWP (Universal Windows Platform).

Kusiphakeli nakwiklayenti, I-RTSP ingeze ukusekelwa kwezindlela zokukhohlisa (ukuskrola ngokushesha lapho ugcina isithombe), esichazwa kusimo se-ONVIF (Open Network Video Interface Forum).

Izinsizakalo Zokuhlela ze-GStreamer zengeza ukusekelwa kwemigqa yesikhathi esidaliwe, izivinini ezenzelwe isiqeshana, kanye nekhono lokusebenzisa ifomethi ye-OpenTimelineIO.

Ngaphezu kwemibhalo yokwakha esekwe ku-Autotools isusiwe futhi iMeson manje isetshenziswa njengethuluzi lamathuluzi eliyinhloko lomhlangano.

Kwezinye izinguquko ezigqamile yale nguqulo entsha:

• I-API entsha esezingeni eliphakeme, iGstTranscoder, iphakanyisiwe engasetshenziswa kuzinhlelo zokusebenza zokudlulisa amafayela kusuka kufomethi eyodwa kuya kolunye.
• Kungezwe ukusekelwa kwe-AFD (Incazelo Yefomethi Esebenzayo) ne-Bar Data codec set.
• Isici se-qmlgloverlay sesingeziwe ukuvumela indawo ye-Qt Quick ukuthi ivele ngaphezulu kokusakazwa kwevidiyo okungenayo.
• Isici se-imagesequencesrc singeziwe ukuze kube lula ukwenziwa kokulandelana kwevidiyo kulandelana kwezithombe ze-JPEG noma ze-PNG.
• Kufakwe i-dashsink element ukukhiqiza okuqukethwe kwe-DASH.
• Kungezwe into ye-dvbsubenc yokufaka ikhodi engezansi kwe-DVB.
• Kungenzeka ukupakisha imifudlana ye-MPEG-TS ngesilinganiso esincane esinqunyelwe nokusekelwa kwe-SCTE-35, ngendlela ehambisana namanethiwekhi wethelevishini wekhebula.
• I-Rtmp2 yaqaliswa ngokusetshenziswa kweklayenti elisha le-RTMP ngezinto zomthombo nezamukeli.
• I-RTSP Server ingeza ukuxhaswa kwekhanda ukulawula isivinini nokukala.
• Kungezwe i-svthevcenc, isifaki khodi sevidiyo esingu-H.265 esuselwa kusifaki khodi se-Intel's SVT-HEVC.
• Kungezwe i-vaapioverlay element yokuqamba usebenzisa i-VA-API.
• Izinto ze-splitmuxsink ne-splitmuxsrc manje zisekela ukusakazwa kwamavidiyo asizayo (AUX).
• Izinto ezintsha zethulwe ukwamukela nokukhiqiza ukusakazwa kwe-RTP kusetshenziswa i- "rtp: //" URI.
• Kungezwe isici se-rpicamsrc sokuthwebula ividiyo yekhamera yebhodi le-Raspberry Pi.
• Ukwethulwa kolwazi okuthuthukisiwe nokulungiswa kwevidiyo nge-High Dynamic Range (HDR).

Okokugcina uma ufuna ukwazi kabanzi ngayo mayelana nale nguqulo entsha yeGstreamer ungabheka i-changelog Kulesi sixhumanisi esilandelayo.

Ungayifaka kanjani iGstreamer 1.18 ku-Ubuntu nakwezinye izinto?

Uma unentshisekelo yokufaka iGstreamer 1.18 ku-distro yakho Ungakwenza ngokulandela izinyathelo esabelana ngazo ngezansi.

Inqubo isebenza kokubili kunguqulo entsha ye-Ubuntu 20.04 kanye nezinguqulo zangaphambilini ngokuxhaswa.

Ukufaka, kufanele sivule ukuphela (Ctrl + Alt + T) futhi kulo sithayipha imiyalo elandelayo:

sudo apt-get install gstreamer1.0-tools gstreamer1.0-alsa gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav

Futhi ngomumo ngalo, bazobe sebevele befake iGstreamer 1.16 kusistimu yabo.
