0002655: some frozen frames in clip when viewing in clip/project monitor and after render

Notes

Reduced the project to just one clip and then created brand new project with just that same clip. Issue still present. ie clip shows same frame near start of clip for 5-10 frames. Issue is visible in clip monitor, in project monitor (after adding clip to start of timeline) and after render using default h264 profile. If I enable proxy clips the issue dissappears (or at least reduces to the very first frame). proxy clip config is: -f mpegts -acodec libmp3lame -ac 2 -ab 128k -ar 48000 -vcodec mpeg2video -g 5 -deinterlace -s 960x540 -vb 8000k playing the same clip from command-line with ffplay, melt, totem, mplayer does not show frozen frames the clip I am using is: http://www.realtsp.com/download/IMGA0191.MP4 [^] this clip also does it: http://www.realtsp.com/download/IMGA0156.MP4 [^] Here is the trivial projcet: http://www.realtsp.com/download/Debug.kdenlive [^]

Given this is kdenlive 0.8.3, could this be related to some lib change in ubuntu 12.04, because these clips were behaving fine earlier in the year..? What other libs could this be related to, I could provide versions in both 11.10 and 12.04 and test in both potentially.

(0008136) oschonrock (reporter) 2012-06-22 14:33 edited on: 2012-06-22 14:38	ok..have now tested on an ubuntu 11.10 machine and the result is different, ie the problem does not exist. Clips plays perfectly in clip monitor and in project monitor on timeline. Also I have confirmed that the playing of proxy clips above is not a 100% "workaround" as it is still frozen for exactly 1 frame. In something like totem or in kdenlive on the 11.10 machine the 1st 2 frames are different..ie as soon you hit "right arrow" from first frame, you get movement (see the flag blowing in wind at top of IMGA0191.MP4 test clip linked to above). On ubuntu 12.04 the un-proxied clip is "stuck" on 1st frame for about 5 frames. With proxied-clip it is "stuck" for 1 frame (ie the 1st 2 frames look identical). Here are the version of the working 11.10 machine: ffmpeg 4:0.7.6-0ubuntu0.11.10.1 frei0r-plugins 1.3.0+git20120530.dcb0dd04-0ubuntu0~sunab~oneiric1 kdenlive 0.9.2-0ubuntu0~sunab~oneiric1 melt 0.7.8-0ubuntu0~sunab~oneiric3 so which lib could it be? ffmpeg or something else? or maybe its a bug in mlt 0.8.0, because the 11.10 machine seems to be running 0.7.8 which is the max version that the sunab/kdenlive-release repo provide for 11.10 oneirix Need some help on how to narrow it down further...

(0008137) oschonrock (reporter) 2012-06-22 14:59	ok..another test ubuntu 12.04 with sunab/kdenlive-svn same problem and behaviour as ubuntu 12.04 with sunab/kdenlive-release versions: ffmpeg 4:0.8.3-0ubuntu0.12.04.1 frei0r-plugins 1.3.0+git20120612.b6528c5f-0ubuntu0~sunab~precise1 kdenlive 0.9.3+git20120621.4d988e59-0ubuntu0~sunab~precise1 melt 0.8.1+git20120621.9358509a-0ubuntu0~sunab~precise1

(0008138) oschonrock (reporter) 2012-06-22 15:03	so..not being an expert on the interaction of the lib supporting kdenlive my current guess is, that the issue could be between: ffmpeg 0.7.6 => 0.8.3 or melt 0.7.8 => 0.7.9

(0008206) oschonrock (reporter) 2012-08-23 13:31 edited on: 2012-08-23 13:33	I have just rested with the following and the issue now seems resolved: ffmpeg 4:0.8.3-0ubuntu0.12.04.1 frei0r-plugins 1.3.0+git20120612.b6528c5f-0ubuntu0~sunab~precise1 kdenlive 0.9.3+git20120815.72a8dbe8-0ubuntu0~sunab~precise1 kdenlive-data 0.9.3+git20120815.72a8dbe8-0ubuntu0~sunab~precise1 libmlt++3 0.8.1+git20120817.99d95a01-0ubuntu0~sunab~precise1 libmlt-data 0.8.1+git20120817.99d95a01-0ubuntu0~sunab~precise1 libmlt5 0.8.1+git20120817.99d95a01-0ubuntu0~sunab~precise1 melt 0.8.1+git20120817.99d95a01-0ubuntu0~sunab~precise1 I am unable to update bug status...but consider this resolved with latest git packages on ubuntu 12.04 64 bit. I will update here if it re-occurs
