[Mlt-devel] Question about decklink producer

[j-b-m <j-...@us...>]

Hi.

I made a few tests with the Decklink producer, using an Intensity Pro card. I 
can correctly preview the video:

melt -profile atsc_1080i_50 decklink:0

However, when I try to encode the stream using an avformat consumer, the 
process quickly eats all my memory (goes up to more than 1 Giga in 20 seconds) 
and then freezes my system.

I used the following command to encode:

melt -profile atsc_1080i_50 decklink:0 -consumer avformat:test.mpg 
vcodec=mpeg2video minrate=0 b=6000k acodec=mp2 ab=128k ar=48000

I tried a few other encoding params without more success. Any ideas? Is it 
because encoding is too slow and MLT caches more and more frames? Did anybody 
succeed in capturing from the decklink producer to a file?

regards
