Impossible to encode from an avisynth script about ffmbc HOT 7 CLOSED

Can you please provide the ffmpeg commandline and its output like requested ?

Thanks.

Sorry. Here is the command line and the output using a simple Avisynth script. 
The 
"*** drop!" warning only occurs when we use Avisynth, and the output file is 
always 
empty. in this case. 

Encoding the same input file without using Avisynth works well. 

Thank you.

Could you please try with 0.4-rc1 ?

the same here:
The file is self contained QuickTime loaded via QTInput() avisynth plugin 
because
without avisynth I get [dvvideo @ 0x179aa10]AC EOB marker is absent pos=66

I understand there is DV decoding bug, which should be fixed.
Can you rerun the command with -v 4 to have vsync info ?

Unfortunately I cannot test avisynth support myself, so this will be hard to 
debug. 

Thank You for the quick response:)
I must say that even with "[dvvideo @ 0x16baa00]AC EOB marker is absent pos=xx"
message the result seems to be OK, but was worried about that message and 
because of
that I decided to use QuickTime decoder via avisynth for DV decoding
Here is the -v 4 test:
