I see you are building MLT yourself. You need either the gtk or the qt module
built into MLT in order to display text.

I don't have 0.9.6 handy, but I tried 0.9.3 and latest git head and they both
work fine.
When you run this command, what do you see?#melt color:white -attach
dynamictext:#timecode#

I hope its not a version issue? I haven't tested it on earlier versions of
melt. Can someone else try it with 0.9.6?

You need to tell the dynamic text filter what text you want to display:
melt -verbose -profile dv_pal /Volumes/XSAN/test000.mov -attach
dynamictext:#timecode# -consumer decklink

I was trying to add timecode overlay using following command without any
success.. what is wrong with the following command? is there an argument
missing?
melt -verbose -profile dv_pal /Volumes/XSAN/test000.mov -attach dynamictext
-consumer decklink

I tried that one also but adding reset_timestamps=1 to melt solved the issue.
I was exploring the API for building custom application and it was a really a
great experience.. I would also like to add a second consumer for monitoring
captured feed in VLC so trying multi consumer now.
Thanks for a wonderful product.

Also, you can compile ffmpeg to use decklink as input device and just use

Thanks,
While waiting for your reply, I updated ffmpeg to version 2.4.3 and melt to
0.9.2 and now I am getting a warning "Using AVStream.codec.time_base as a
timebase hint to the muxer is deprecated. Set AVStream.time_base instead."
Anyways splitting works now but only first movie contains valid frames, rest of
the movies are created with blank frames
melt -verbose -profile dv_pal decklink:1 -consumer avformat:test%03d.mov
vcodec=prores acodec=pcm_s16le f=segment segment_format=mov segment_time=10
Can you guess what is wrong with files created after first one?
No, you probably need to debug it and send a patch.
