[13:13] <JoshX> good day..
[13:13] <JoshX> Hello, Is it possible to get info about an mp4 file which should countain 1800 frames (60 seconds, 30fps) but only contains 1560 frames (240 frames missing, 8 seconds) to find out which frames are missing?
[13:13] <JoshX> or to put it in other words, can i get a list of all the frames in the file with their start and end time and frame number for example?
[13:40] <Daemon404> JoshX, maybe ffprobe -show_frames file.mp4
[13:41] <Daemon404> but this belongs in #ffmpeg
[13:42] <JoshX> yes and i got my answer.. sorry about that
[13:42] <wm4> does ffprobe still show wrong frame duration for mov?
[13:43] <JoshX> and the show_frames will probably work in my case :) i just need the 'units' for pkt_dts=553
[13:43] <Daemon404> wm4, only the last frame had wrong duration iirc
[13:44] <wm4> JoshX: ffprobe also shows the timestamps in seconds, doesn't it
[13:47] <JoshX> yes it does
[13:47] <JoshX> writing a small script now to find gaps in the timestamps
[13:50] <cone-666> ffmpeg.git 03Michael Niedermayer 07master:bbbc8c618884: avformat/mov: Check ctts_count before use
[14:06] <Daemon404> JoshX, -of json is your pal
[14:06] <Daemon404> easily consumable by most languages
[14:21] <Daemon404> michaelni, supposedly 'colr' for isombff is defined in 14496-12:2012
[14:21] <Daemon404> i cant find any copies floating around though
[14:21] <Daemon404> only the outdated 2005 ver
[14:38] <michaelni> Daemon404, it lists nclx, rICC and prof as allows color_types and refers to  A.7.2 of ISO/IEC 29199-2 for nclx with "but note that the full range flag is here in a different bit position"
[14:39] <Daemon404> right
[14:39] <Daemon404> it differs slightly from the mov colr
[14:42] <michaelni> anyone interrested in isom colr: http://pastebin.com/A3MhtacY
[14:44] <Daemon404> wait you can embedd icc profiles?
[14:44] <Daemon404> ewwwwwwwwww
[14:47] <thardin> yes
[14:47] <Daemon404> time for vlc to link in lcms2?
[14:47] Action: Daemon404 runs

[17:53] <JoshX> Daemon404: if i were to 'miss' or 'mangle' an i frame in a vcodec copy stream, would ffmpeg discard all frames untill the next iframe?
[17:53] <JoshX> i seem to miss an iframe, and then miss the next 29 pframes too and then the stream just picks up at the next iframe with a resulting 1 second gap
[17:54] <JoshX> if this ffmpegs way to cope with a video loss and to produce a clean output, preventing mpeg artefacts?
[17:54] <JoshX> or is there something entirely different going on?
