Quick way to show Picture Type in AVC or MPEG2 stream

Lyris · 23rd February 2013, 06:54

Hey forum,
When authoring BDs with Sony DoStudio (previously Netblender), I ideally want to have the chapter marks on I-Frames.

Trouble is, DoStudio doesn't have any feedback on whether or not the timecode you gave it actually is an I-frame.

Is there some sort of Avisynth filter that can display the coded picture type on screen so I can be sure?

For MPEG2 you can use VDub and the fccHandler mpeg2 plugin. It will tell you the type of every frame.
For AVC, try to take a look at AVIDemux. You probably need to put your raw AVC stream in a container.

Perhaps the three consecutive posts here can assist:-

EDIT: You can use 'ShowFrameNumber()' on source clip or
'Show=true' in either Prune() or FrameSelect() to show the frame numbers
in extracted I/KEY frame only clips.

EDIT: Or just use the generated text list of I/KEY frames.

EDIT: This method allows programatical control rather than just viewing I frame numbers.

LoadPlugin("DGDecode.dll")
MPEG2Source("video", info=1)

and

LoadPlugin("ffms2.dll")
Import("ffms2.avsi")
FFVideoSource("video").FFInfo()

For AVC and VC1 you can use DGDecNV:

DGSource(...,debug=true)

Or FFDShow with OSD ON - then select information to display as you like.
