How to get the number of frames of a video file with ffprobe?

[marcorocchini]

"v:\automazioneclip\virtualdub\FFProbe" shouldn't there be a .exe at the end on Windows?

but no make difference (seems to me) if work also without the .exe

and however in this case .. do make differences: batch (in my pc) don't work in everycase. But shure ndjamena have modify it to work also in the case of a variable framrate, shure is only a small character or a sintax error, or an error in my script that I cannot identify

marcorocchini , Not too sure what you want to do here but if you want to find the number of frames and use in ffprobe then my last post shows how to find the variable and add it back into your script for ffprobe if you want to use it. What you want ffprobe to show looks confusing to me since there are a lot of variations here.

If you just want to find the number of frames then my first post will do it. It's a pretty simple use of MediaInfo CLI (thats the Command Line version) available at http://mediaarea.net/en/MediaInfo/Download/Windows. The 2 files you need are the Mediainfo.exe (CLI version) and the Mediainfo.dll (from CLI version). Just be sure to follow the punctuation and Capitalization .

the ndjamena's summarily works, his last to my pc go wrong but it's probably a little thing, maybe the point

if "%% CType =="video"

maybe it something of undefined: I try with a .mxf file

I think his procedure try to retrive the variabile framerate and puts a conditional. However thanks to both

in the same script I use also mediainfo cli with the updated mediainfo.dll 07.70.00 and it works well to retrive some information

I'm attempting to clean up your script to make it easier to work with. I've changed some of the variable names, you may have to alter the rest of the batch to match. FFProbe outputs XML if there's itunes data in an mp4, I haven't figured out how to deal with that properly.

[marcorocchini]

but it work, and recognize time base and other info, absolutly considerable! with 15/20 file of various type seems work well
big thanks. If I'm not wrong, it do a real count of frames into a video file

Best method (direct)

Best method:

Cmd ->

ffprobe.exe -v error -select_streams v:0 -show_entries stream=r_frame_rate,duration -of default=nw=1 "d:\movies\The.Matrix.1999.1080p.BrRip.x264.YIFY.d ut.mp4"

Result ->

r_frame_rate=24000/1001
duration=8177.794625

Calculation ->

Frames=24000/1001*8177.794625=196071

Proof ->

ffmpeg -i "d:\movies\The.Matrix.1999.1080p.BrRip.x264.YIFY.d ut.mp4" -f null /dev/null
