Trying to understand mplayer + EDL list usage

[Selur]

I'm trying to get my head around EDLs in mplayer.
What I want to archive is that I want to only decode/analyse roughly a total of 100 frames across 9 different places across my input.
My input is 23.976 fps (so each frame is displayed ~41ms) and has a duration of 2710 seconds.
So my thought was to split the source into 10 sections using an EDL (http://mplayerhq.hu/DOCS/HTML/en/edl.html):

0 406.538 0
407.002 678.027 0
678.492 949.517 0
949.981 1221.01 0
1221.47 1492.5 0
1492.96 1763.99 0
1764.45 2035.48 0
2035.94 2306.97 0
2307.43 2578.45 0
2578.92 2710.75 0

so that the frames between the sections gets analysed.
In my case that would be 465ms which is roughly 12 frames.
So if everything works the way I understood it, the output should consist of roughly 100 frames.
With that in mind I saved my list into a file named cropEDL.txt and called:

"G:\Hybrid\mplayer_64.exe" -noframedrop -speed 100 -quiet br://10 -bluray-device "Y:\SULXMY~E" -tsprobe 100000000 -nosound -vo null -ao null -nosub -fps 23.976 -vf cropdetect=24:2 -edl "h:\cropEDL.txt"

Problem is that this doesn't decode/analyse just roughly 100 frames, but more like all frames.

Is someone here who has some experience with MPlayer and EDL lists who can shed some light on where I go wrong?

mplayer edl works ok for me

Try a different mplayer build, and/or try naming the edl the same name as input video (e.g. "video1.mp4" , "video1.edl")

Each of those listed are SKIPPED, so the part you are wanting are the parts in between? I see only 9 clips in between, and since the first starts at zero and the last is longer than the total duration that you mentioned, it looks like there are only 9 clips.

I haven't used this feature in mplayer, so can't help you too much. Too bad they didn't use industry-standard nomenclature (timecode notation, using elements to keep), would make for easier translation from other EDL files.

I would agree w/ pdr re:_same name & "edl" extension, though it shouldn't make a difference. Also, does your video file not have an extension?

There is only one clip, and yes, I only want to analyze 9 sections of that clip.

Also, does your video file not have an extension?

"-bluray-device" is fed with a folder not with a file. "br://10" tells mplayer which playlist should be selected.

I would agree w/ pdr re:_same name & "edl" extension, though it shouldn't make a difference.

Renaming the edl to the 'foldername.edl' doesn't change a thing.

output says that the edls are read:

Playing br://10.
Read 10 EDL actions.

but since the crop detection doesn't stop, there seems to be something off.

[poisondeathray]

Debug it step by step like you would for anything. Start by removing -vf cropdetect, test, then remove something else, test... etc...

I'm guessing it's because you're reading from a mpls and a problem with libbluray. So I would actually start with a test video
and work from there

Okay, so no-one sees a direct problem.

Using a clip with a play length of 6180 seconds, adjusting the last edl entry accordingly and shrinking the call to:

"G:\Hybrid\mplayer_64.exe" -edl "h:\wmpreperation.edl" "F:\soccer\wmpreperation.m4v"

doesn't help and switching to a build from http://mplayerwin.sourceforge.net/downloads.html doesn't help either.
