Jinak na mém videu je i menší datový tok, takže to by snad měl zvládat. Mohu poprosit místní znalé parametrů mencoderu (příp. asi perspektivnějšího ffmpeg), jaké parametry bych měl použít, aby mi vylezl odpovídající funkční profil v mediainfo? Předem díky moc.
-xvidencopts bitrate=1500:pass=2:threads=2:vhq=4:bvhq=1:quant_type=h263:chroma_opt
no a seka se ti to i bez zvuku? taky jesem si vsimnul, ze mas -xvidencopts dvakrat, to asi nevadi, ale stejne ...
jinak jeste nerozumim tem filtrum, ja je mam takto: -sws 2 -vf crop=688:560:18:8,hqdn3d,scale=-9:-10,harddup
akurat si oprav crop, mozna neni vubec potreba a scale=160:128
no a aspect ratio je sice v souboru zapsany, ale vetsina prehravacu ho ignoruje, muzes s nim manipulovat pomoci http://www.moitah.net/download/latest/MPEG4ModifierCL.zip, jde pustit pres mono
jeste se podivej tim mpeg4modifier, jestli ty fungujici soubory nemaji packed bitstream, mencoder dela jen bez, ale mpeg4modifier ho umi pridat/oddelat
