Sziasztok!<br>
<br>
Gyakran találkozok olyan filmekkel, melyek .mkv kiterjesztésű
formátumba vannak kódolva. <br>
Ezt az asztali DVD lejátszók 90%-a nem ismeri, továbbá az 500MHz-es
vagy annál lassabb gépeken akadozik, talán a túl nagy számításigényű
hang miatt. (128MB RAMmal)<br>
Érdekelne olyan megoldás is, mely lejátszásnál lecsökkenti a gépigényt,
ugyanis nincs többcsatornás hangkártyám, csak stereo.<br>
<br>
Ezzel a parancssorral próbáltam aviba kódolni:<br>
mencoder -ovc copy -oac mp3lame bemenet.mkv -o kimenet.avi<br>
<br>
Eeredmény:<br>
