5 amathiphu noma amaqhinga athakazelisayo wokusebenza namavidiyo

Ngokusebenza namavidiyo, kunconywa ukuthi usebenzise I-Mencoder o I-Ffmeg, kodwa ... yini le?

I-Mencoder isifaki khodi samahhala samahhala esikhishwe ngaphansi kwelayisense ye-GPL efakiwe kwisidlali semidiya se-MPlayer ngenkathi Ffmpeg iqoqo lesoftware ekuvumela ukuthi urekhode futhi uguqule amavidiyo nomsindo.

esingakwenza ngabo?

Ukuphendula lo mbuzo wesibili, ngikulethela "amaqhinga" futhi ngikushiyela kuwe ukuthi wahlulele ukuthi uyakufanelekela yini ukuthola indawo kukhompyutha yethu.

1- Khipha ithrekhi yomsindo kuvidiyo:

mplayer -vo null -hardframedrop -ao pcm:file=audio.wav video.avi

Idatha:
ividiyo.avi: ividiyo esifuna ukukhipha kuyo umsindo.
umsindo.wav: igama lefayela elenziwe ngomsindo.

2- Zungezisa ividiyo:

mencoder -vop rotate=2 -oac pcm -ovc lavc ./normal.avi -o ./rotada.avi

Idatha:
phenduka = ​​<0-7>: Rotate and flip (uyazikhethela) isithombe +/- 90 degrees. Ngamapharamitha aphakathi kuka-4-7 ukuzungezisa kwenziwa kuphela uma i-geometry yefilimu ime mpo hhayi evundlile.
evamile.avi: ividiyo esifuna ukuyishintshanisa.
azungezise.avi: igama levidiyo ekhiqizwe ngokuzungezisa okucacisiwe.

3- Bona ividiyo kusuka kuzithombe ze-JPG:

mplayer "mf://*.jpg" -mf fps=15

Dala ividiyo:

mencoder "mf://*.jpg" -mf fps=15 -ovc lavc -o ./dest.avi

Idatha:
mf: //*.jpg: thatha zonke izithombe ngalesi sandiso, singazisebenzisa ne-PNG: mf: //*.png
fPS: Isetha ijubane lokuguquka phakathi kwezithombe.
khanyisile: igama levidiyo ekhiqiziwe.

4- Hlanganisa ividiyo nomsindo:

ffmpeg -i sonido.wav -i video.avi videoconaudio.avi

Idatha:
umsindo: ifayela lomsindo.
ividiyo.avi: ifayela levidiyo.
videocudioudio.avi: igama lefayela levidiyo ngomsindo ocacisiwe.

5- Guqula i-avi ibe yi-gif.

ffmpeg -i video.avi -pix_fmt rgb24 gif_generado.gif

Idatha:
ividiyo.avi: ividiyo esifuna ukuyiguqula ibe yi-GIF.
gif_generated.gif: igama lefayela elitholwe kuvidiyo.
amg24: sicacisa imibala.
