Tom qab ntau tshaj ib xyoos ntawm kev txhim kho tso tawm , tus ntoo khaub lig-platform txheej ntawm cov khoom sau hauv C rau kev tsim ntau hom kev siv multimedia, los ntawm media player thiab audio / video file converters, mus rau VoIP daim ntawv thov thiab streaming systems. GStreamer code muaj ntawv tso cai raws li LGPLv2.1. Nyob rau tib lub sijhawm, kev hloov tshiab rau gst-plugins-puag 1.16, gst-plugins-zoo 1.16, gst-plugins-phem 1.16, gst-plugins- dab tuag 1.16 plugins muaj, nrog rau gst-libav 1.16 khi thiab cov gst-rtsp-server 1.16 streaming server. Ntawm qib API thiab ABI, qhov kev tso tawm tshiab yog rov qab sib xws nrog 1.0 ceg. Binary tsim los sai sai rau Android, iOS, macOS thiab Windows (ntawm Linux nws raug pom zoo kom siv pob khoom los ntawm kev faib khoom).
Ntsiab GStreamer 1.16:
- Lub WebRTC pawg tau ntxiv kev txhawb nqa rau P2P cov ntaub ntawv raws tau siv los ntawm SCTP raws tu qauv, nrog rau kev txhawb nqa rau xa cov ntaub ntawv sib txawv ntawm cov ntaub ntawv multimedia nyob rau hauv ib qho kev sib txuas thiab muaj peev xwm ua haujlwm nrog ntau lub TURN servers (STUN txuas ntxiv mus hla tus neeg txhais lus chaw nyob);
- Ntxiv kev txhawb nqa rau AV1 video codec hauv Matroska (MKV) thiab QuickTime / MP4 ntim. Ntxiv AV1 chaw tau raug siv thiab cov ntaub ntawv tawm tswv yim txhawb nqa los ntawm tus encoder tau nthuav dav;
- Ntxiv kev txhawb nqa , nrog rau kev muaj peev xwm txheeb xyuas thiab rho tawm lwm hom kev sib koom ua ke ntawm cov ntaub ntawv video (Cov ntaub ntawv txuas ntxiv, cov ntaub ntawv ntxiv, xws li suab thiab metadata, kis tau los ntawm cov kev cuam tshuam digital hauv qhov tsis pom ntawm cov kab scan);
- Ntxiv kev txhawb nqa rau uncoded (raw) suab yam tsis muaj kev hloov suab hauv lub cim xeeb (Tsis yog-Interleaved, sab laug thiab txoj cai audio channels muab tso rau hauv cov blocks cais, es tsis txhob hloov cov channel hauv daim ntawv "LEFT|RIGHT|LEFT|RIGHT|LEFT|RIGHT" );
- Txav mus rau lub hauv paus txheej ntawm plugins (gst-plugins-base) (chav kawm rau kev sib xyaw ua yeeb yaj kiab), (ib qho kev hloov kho rau videomixer) thiab OpenGL tov khoom (glvideomixer, glmixerbin, glvideomixerelement, glstereomix, glmosaic), uas yav tas los tau muab tso rau hauv "gst-plugins- phem" teeb;
- Ntxiv tshiab teb alternation, nyob rau hauv uas txhua tsis yog ua tiav raws li ib tug cais teb nyob rau hauv interlaced video nrog kev sib cais ntawm sab sauv thiab sab teb nyob rau theem ntawm tus chij txuam nrog tsis;
- Kev them nyiaj yug rau WebM hom thiab cov ntsiab lus encryption tau ntxiv rau Matroska media ntim unpacker;
- Ntxiv ib qho tshiab wpesrc caij uas ua haujlwm raws li lub cav-based browser (tso cai rau koj kho qhov browser tso zis raws li cov ntaub ntawv qhov chaw);
- Video4Linux muab kev txhawb nqa rau HEVC encoding thiab decoding, JPEG encoding thiab txhim kho dmabuf ntshuam thiab xa tawm;
- Kev them nyiaj yug rau VP8 / VP9 kev txiav txim siab tau ntxiv rau lub tshuab txiav video siv NVIDIA kho vajtse nrawm GPU, thiab kev txhawb nqa rau H.265 / HEVC kho vajtse nrawm nrawm tau ntxiv rau lub encoder;
- Ntau qhov kev txhim kho tau ua rau msdk plugin, uas tso cai rau kev siv cov khoom siv nrawm nrawm rau kev encoding thiab txiav txim siab ntawm Intel chips (raws li Intel Media SDK). Qhov no suav nrog ntxiv kev txhawb nqa rau dmabuf ntshuam/export, VP9 decoding, 10-ntsis HEVC encoding, video post-processing thiab dynamic daws teeb meem hloov;
- ASS/SSA subtitle rendering system tau ntxiv kev txhawb nqa rau kev ua ntau yam subtitles uas cuam tshuam rau lub sijhawm thiab tso saib lawv ib txhij ntawm qhov screen;
- Kev txhawb nqa tag nrho tau muab rau Meson tsim qhov system, uas tam sim no pom zoo rau kev tsim GStreamer ntawm txhua lub platform. Kev tshem tawm ntawm Autotools kev txhawb nqa yuav tsum nyob rau hauv ceg tom ntej;
- Cov qauv tseem ceeb ntawm GStreamer suav nrog kev khi rau kev txhim kho hauv cov lus Rust thiab ib qho module nrog plugins hauv Rust;
- Kev ua tau zoo tshaj plaws tau ua tiav.
