Hi,
I just came across an encoding command that results in an error just
before the encoding is finished. The command was:
ffmpeg -i "widescreen.dv002.dv" -f image2pipe -vcodec pgmyuv -y
/dev/stdout | pgmtoy4m -r 25:1 -i b -a 118:81 | y4mscaler -I sar=118:81 -O
infer=exact -O infer=preserve_x -O size=720x352 -O sar=10:11 | y4mscaler
-O chromass=420_MPEG2 -S option=sinc:4 | y4mspatialfilter -L 4,.90,4,.90
-C 3,.810000,3,.810000 | yuvdenoise -s 1,3,3 -t 4,31,31 -g 0,255,255 |
y4mscaler -I active=720x352+0+0cc -I matte=720x480+0+0cc -O preset=DVD |
yuvcorrect -Y LUMINANCE_3.00_30_225_0_255 -Y
CHROMINANCE_0.0_1.00_128_1.00_128_0_255 | yuvcorrect -Y
LUMINANCE_1.0_16_235_16_235 -Y CHROMINANCE_0.0_1.0_128_1.0_128_16_240 |
y4mscaler -I active=720x352+0+0cc -I matte=720x480+0+0cc -O preset=DVD |
yuvfps -n -r 30000:1001 | tee "./EncoderPipe_23295" | mpeg2enc -M 0 -f 8
-b 8000 -B 384 -D 10 -K default --cbr -a 2 -N 1.0 -o "./Encoded.m2v"
In case you want to know: This command was generated by a script, it isn't
optimal, I know. :) But anyway, I believe it should not generate this
error message:
INFO: [yuvplay] Playing frame 0122 - 0:00:04.02
INFO: [yuvdenoise] Buffers freed.
INFO: [y4mscaler] End of stream at frame 102.
INFO: [yuvcorrect] End of stream!
INFO: [yuvcorrect] Normal exit: end of stream with frame number 102!

Runtime error (func=(main), adr=9): Divide by zero
(standard_in) 1: parse error
bash-2.05b$
The resulting output file is empty. When I remove the yuvfps part from the
above command, everything works as expected.
Any help on this one would be greatly appreciated!
Cheers,
Dik
