Hello,
I try to build a mpeg file as a dvdauthor input (I am a beginner).
So I transform each image as m2v file
(q1.m2v
Mpeg 2 Video File
Estimated Duration: 00.45s
Aspect ratio 4/3 (TV)
Interlaced, chroma format: 4:2:0
Video Format: PAL
Size [720 x 576] 25.00 fps 7.50 Mbps
)
cat q1.ppm | ppmtoy4m -n50 -F25:1 -A59:54 -I p -r -S 420mpeg2 |
mpeg2enc -n p -f8 -b7500 -a2 -I 0 -o q1.m2v
cat q2.ppm | ppmtoy4m -n50 -F25:1 -A59:54 -I p -r -S 420mpeg2 |
mpeg2enc -n p -f8 -b7500 -a2 -I 0 -o q2.m2v
Then I build a audio file
ffmpeg -ab 224 -ar 48000 -ac 1 -t 4 -i soung.mp3 menu_audio.ac3
Then I put together the different part of the movie (mpgjoin)
mpgtx -j q1.m2v q2.m2v -o joined.m2v
And I convert the element to be compatible with the dvdauthor tool (I
think it it the -f8 argument).
mplex -f8 -o firstplay.mpg joined.m2v menu_audio.ac3

**ERROR: [mplex] Need to split output but there appears to be no %d in
the filename pattern firstplay.mpg
I thing this problem is a consequence of the join operation, because the
script works when the file is not catenated.
Question :
1) Why does not this method work ? Any idears or pointers
2) Do you know a solution to convert the list of image into a movie ? If
possible, the duration of each picture must be tuned (2s for the first
one, 4s for the second, 1s for the third, ...)
Thanks.
