ffmpeg: extracting images from video together with their frame numbers? -


i'm extracting images (variable framerate) .avi file with

ffmpeg -i movie.avi -r 25 %05d.png

(the -roption should equivalent filter -vf='fps=fps=25'), know frame number in original video stream each generated image corresponds to. there easy way that?

if use

ffmpeg -i movie.avi -vsync 0 %05d.png

no frames duplicated or dropped, each frame serial no. should correspond index in video.

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
