CarlFKmithro: I am trying to figure out the end time or duration of a gst-switch output file.   any suggestions?23:12
mithroCarlFK: avconv (ffmpeg) doesn't give you useful information?23:13
CarlFKmithro: guessing I need some switches or something.  $ avconv foo.avi .... File 'foo.avi' already exists. Overwrite ? [y/N]23:14
mithroCarlFK: what would you use with ffmpeg?23:14
CarlFKno clue23:14
mithroCarlFK: how did you do this previously?23:15
CarlFK.dv files have 120,000 byte frames, so filesize and fps23:15
mithroDoes file show anything useful?23:16
CarlFKfoo.avi: RIFF (little-endian) data, AVI, 300 x 200, 30.00 fps, video:, audio: (stereo, 48000 Hz)23:16
mithrogoogle says23:17

CarlFKsurprising: audio Compression mode                         : Lossy23:18
mithroCarlFK: yeah23:19
mithroCarlFK: the whole recording pipeline needs tuning / fixing23:19
CarlFKnb: I have no idea how accurate that is23:19
CarlFKavconv -i foo.avi    Duration: 00:00:00.00, start: 0.000000, bitrate: -2147483 kb/s23:19

mithroCarlFK: okay, my guess is that gstreamer isn't writing out the index after closing the file23:20
mithromencoder -identify -forceidx23:21
CarlFK-identify is not an MEncoder option23:22
mithrotry mplayer instead?23:23
mithroIf that works, somewhere in your pipeline you should generate idx files23:25
mithroheading around to shenki's place now - be back in 1523:33
CarlFKim off to dinner with Sheilas family - prolly a few hours23:33
CarlFKI am going to open a 1/2 baked issue about file duration.  I haven't had time to try your last few suggestions23:35
