How can I determine that from a vdr-1.7.10 recording? Unfortunately vdrsync doesn't work any more :-(.

I don't know how you could find the length; maybe it's a simple calculation from the size of the index.vdr file?

If the recordings store PCR, you could just read the first and last PCR and do some quick math?

Does vdr store the pcr? What do you mean with quick math? Can you post an example? Regards halim

No, it doesn't.

You can take the size of the index file, divide it by 8 and you get the number of frames in the recording. The info file tells you the number of frames per second (at least with newer TS recordings).

That makes it pretty easy! :)

I don't think this calculation is always accurate (i.e. for h264/HD recordings) right now. For a 1080i recording the info file contains "F 25" (shouldn't it be 50 frames for 1080i50?)

Example (recorded with vdr 1.7.10): # ls -la insgesamt 7219260 drwxr-xr-x 2 vdr vdr 59 28. Nov 15:04 . drwxr-xr-x 3 vdr vdr 38 22. Nov 20:12 .. -rw-r--r-- 1 vdr vdr 7389603764 22. Nov 22:13 00001.ts -rw-r--r-- 1 vdr vdr 2901984 22. Nov 22:13 index -rw-r--r-- 1 vdr vdr 681 22. Nov 20:12 info

# grep "^F\ " info F 25

2901984 (size of the index file) / 8 = 362748 (frames) 362748 / 25 (framelength according to info) = 241min 49sec (wrong!) 362748 / 50 (real framelength) = 120min 54sec (actual length)

Can you give me link to a one minute recording where I can see this?
