Hi, some time ago I fould this program. Compiled without errors but I dont
know how to use it. From the official (?) mpeg4 audio site. Uni Hannover.
Somebody knows more ?
Thanks,
H.
mpeg4_filter -h says this, dont understand it, format of the input files
etc:
CCIR 601 <-> CIF/QCIF/SIF conversion
(c) 1996,1997 Andreas Hutter, TU Muenchen / FhG-IFT
Usage for downsampling:
./mpeg4_filter -s x [-c x] [-f] [-t | -b x | -g x] <input> <output>
<nframe>
Usage for upsampling:
./mpeg4_filter -u x <input> <output> <nframe>
where "input" and "output" indicate the input and output filename
"x" is the upsampling mode and "nframe" is the number of frames
option: -h help
option: -s x number of lines per frame in CCIR format,
x = {576, 486, 480}, DEFAULT is 576
option: -c input sequence is in 4:2:0 format
option: -d input sequence is in "class D format"
option: -f additionally produce SIF format
option: -t input sequence is two level (0,255) alpha plane
option: -b x input sequence is multilevel (0,1,..) alpha plane
x = number of objects (x >= 2)
option: -g x input sequence is grey scale alpha plane
x = threshold level
option: -o x manually adjust active picture area
x = [0 .. 15], offset from left
option: -r x replace first and/or last line to avoid retrace effects
x = [1,2,3], where 1 = first, 2 = last, 3 = both
option: -u x perform upconversion for display
x specifies input format, x = {1, 2, 3, 4, 5}, where
1 = QCIF, 2 = CIF, 3 = SIF->CCIR, 4 = CIF->CCIR, 5 = QCIF->CCIR
