WebM kuya HLS Imibuzo Evame Ukubuzwa Yokuguqulwa

Ngiyifaka kanjani ikhowudi WebM ku HLS ngaphandle kokulahlekelwa ukhwalithi?

Ukufaka ifayela lakho WebM futhi hlela Quality to High Quality in the conversion options. That re-encodes the video at the highest quality setting (CRF 18 for H.264 and VP9 output), which keeps the most detail at the cost of a larger file. The default, Balanced, uses the standard setting. The HLS output gets a codec its container supports: H.264 for MP4, MOV and MKV, VP9 for WebM.

Yini i-codec esetshenziswa yi-HLS?

Kuxhomekeka ku HLS isiqoqi. MP4, MOV kanye MKV output ukusebenzisa H.264, okuyinto idlala ku ngempela wonke ifoni, ibrowser kanye TV. WebM output usebenzisa VP9. AVI, WMV kanye MPEG output ukusebenzisa codecs older labo amafomethi akhiwa.

Ingabe umsindo wami uzohlala ukhona WebM kuya ku HLS?

Yebo, umsindo omkhulu ohambayo udlula, uphinde ukhodwe ku-codec i-HLS idlala, isibonelo, i-AAC ku-MP4 ne-MOV noma i-Opus ku-WebM.

MP4 kuya ku-MOV, ne-AVI, WMV, MPEG, FLV, VOB noma M4V kuya ku-MKV, gcina wonke umsindo ohambayo.

Ingabe ngigcina ifreyimu yesiqalo uma ngiguqula WebM ku HLS?

Yebo. Izinga lefreyimu ligcinwa ngaphandle kokuthi ushintshe: i-24 fps WebM ihlala i-24 fps ku-HLS. Uhlelo lwezinga lefreyimu lingaguqulwa libe yi-60, 30 noma i-24 fps. Lishintsha kuphela inani; alisusanga ividiyo noma lisusa i-3:2 pulldown.

Yini ushintsho lobukhulu befayela phakathi kwe WebM ne HLS?

Kuxhomekeka kulokho okukwenzekayo kuvidiyo. MKV MP4 noma MOV nge default izilungiselelo ikhophi ividiyo umsinga engashintshiwe, ngakho ubukhulu ihlala eduze komthombo. Ezinye izibini eziningi ziphinde zikhophi: a high-bitrate WebM ngokuvamile ephuma ncane, ngenkathi ekhona kakhulu ecindezelwe eyodwa ingakhula. File encane ngaphansi Quality inikeza inzuzo encane, futhi H.265 ku Codec isilungiselelo (MP4, MOV ne MKV) ngokuvamile ncane kuna H.264 ku quality efana kodwa idlala ku amadivayisi ambalwa.

Akukho isikhathi esiqinile: sixhomekeke kude, isixazululo kanye nefomethi efanelekayo. Ukuguquka kuqhutshwa kumaseva ethu we-CPUs ngesoftware encoders; akukho GPU ukukhawulelwa. MKV kuya MP4 noma MOV ngezinhlelo ezijwayelekile zikopisha umsinga wevidiyo futhi zishesha. Ukuphinda-ukuguqula ku-H.264 kuthatha isikhathi eside, futhi WebM (VP9) yinjongo ehamba kancane, izikhathi eziningi ezihamba kancane kune-H.264 ezivivinyweni zethu.

Akukho HDR ukucubungula noma ukudweba kwethoni. Uma ividiyo ikhophiwe (MKV kuya ku-MP4 noma MOV ngezinhlelo ezijwayelekile), i-HDR10 idlula ngaphandle kokuchofoza. Ukuphinde ubhale kabusha i-HDR10 mastering metadata, futhi ngekhwalithi, ubukhulu noma i-frame rate setting ezinye izibini zikhuphula i-video ibe ngombala we-8-bit, ngakho-ke i-HDR WebM ingabonakalisa i-washed out.

Ingabe i-WebM yami yevidiyo ifihlakele ngesikhathi sokushintsha?

Yebo. Amafayela WebM alayishwe phezulu aphathwa kumaseva ethu okuguqula, akukho muntu obhekana nawo, futhi angeke ahlukaniswe.
