<br>
I am trying to play an SD interlaced file out on a Blackmagic
Decklink card but having troubles. I cannot get the following
pipeline to link -<br>
<i>gst-launch-1.0 uridecodebin uri=<a class="moz-txt-link-freetext" href="file:///Volumes/Video/race.mov">file:///Volumes/Video/race.mov</a>
! autovideoconvert ! decklinkvideosink mode=3</i><br>
If I deinterlace then interlace with<br>
<br>
<i>uridecodebin uri=<a class="moz-txt-link-freetext" href="file:///Volumes/Video/race.mov">file:///Volumes/Video/race.mov</a> ! deinterlace !
autovideoconvert ! interlace field-pattern=2:2 ! videoscale !
videorate ! decklinkvideosink mode=3<br>
<br>
</i>This works but if I add audio<br>
<br>
<i>uridecodebin uri=<a class="moz-txt-link-freetext" href="file:///Volumes/Video/race.mov">file:///Volumes/Video/race.mov</a> name=decoder
decoder. ! deinterlace ! autovideoconvert ! interlace
field-pattern=2:2 ! videoscale ! videorate ! decklinkvideosink
mode=3 decoder. ! audioconvert ! decklinkaudiosink</i><br>
<br>
The audio plays at the correct speed and pitch but stutters as if
half the samples are missing.<br>
<br>
What is the correct pipeline for playing interlaced files to a
Decklink card in interlaced mode?<br>
<br>
My source files are DV in a QT container, also tried ProRes.
Using pre-compiled binaries (v1.8) for OS X (Yosemite).<br>
<br>
As for HD, even the above trick does not work.<br>
<br>
Regards,<br>
