[Mjpeg-users] Strange mplex problem

[Hans v. d. M. <ha...@uk...>]

Hi,

This used to work, but after updating it's a no-go:

mpeg2enc        --format 2                              \
                --aspect 2                              \
                --video-bitrate 1800                    \
                --nonvideo-bitrate 224                  \
                --video-norm p                          \
                --motion-search-radius 24               \
                --reduction-4x4 2                       \
                --reduction-2x2 1                       \
                --sequence-length 690                   \
                -o [videooutput]

Works fine:

toolame -b 224 [in] [out]

Works fine:
Input File : 'out.wav'   44.1 kHz
Output File: 'out.m1a'
224 kbps MPEG-1 Layer II j-stereo Psy model 1

Avg slots/frame = 731.429; b/smp = 5.08; bitrate = 224.000 kbps


But:

mplex -f 2 -o [output]

with previous output files doesn't!

**ERROR: [mplex] Too many frame drops -exiting

Any ideas?

Thanks in advance!
