rendering fails

Any idea why rendering is failing on my project?

All profiles end up with 0% and a waiting status forever and I see nothing interesting in the debug output.

Using based packaging for kdenlive 0.7.3-0.0svn3376 and:

Hmm, downgrading kdenlive from svn3376 to plain 0.7.3 seems to help. At least rendering starts and an output file starts getting bigger.

Maybe you should try to run the Config Wizard from the "Settings" menu and make sure it correctly finds all MLT related stuff, you can also check in Kdenlive Settings dialog if in the tab "Environment", the path to "inigo" is set correctly. Last, you can try to delete your ~/.kde/share/config/kdenliverc file

Rendering worked but output contains quite a few bugs. I'm mixing pal dv, 720p30 and 1080i videos and still images. Major gripes are:

* 1080i videos[1] play with double speed, audio with normal speed

The files are 'double speed' also on the kdenlive time line, but playback during editing is so slow I had not noticed this. ffplay and mplayer play these fine, inigo is jerky. I converted these from the original mts files with ffmpeg, perhaps I made something wrong since ffmpeg -i complains:

Seems stream 0 codec frame rate differs from container frame rate: 60000.00 (60000/1) -> 59.94 (60000/1001)
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'tommin_kamera/Tommin kamera 1/avi/00010.avi':
Duration: 00:00:03.71, start: 0.000000, bitrate: 75575 kb/s
Stream #0.0(eng): Video: mpeg4, yuv420p, 1920x1080 [PAR 1:1 DAR 16:9], 59.94 tbr, 59.94tbn, 60k tbc
Stream #0.1(eng): Audio: aac, 48000 Hz, stereo, s16

For this I will try if the original .mts files work better, sigh.

* mixing interlaced pal dv stream with 720p, and forcing rendering output to be progressive, results in partially deinterlaced output. I noticed a few places where dv stream was not deinterlaced.

For this I think I should deinterlace all .dv files before feeding them to kdenlive. I used to do the same with kino which at some point couldn't handle them both.

I ran config wizard on the svn version, inigo and others are found. Rendering a test project also works. But with my large project wizard failed once complaining at start about inigo or mlt's sdl support, which exists and mostly works from what I can tell, and rendering my project fails to go past waiting state and 0%.

Test project rendering brought this to the log:

//STARTING RENDERING: true , false , "/usr/bin/inigo" , "hdv_720_30p" , "avformat" , "-" ,"/tmp/kde-mcfrisk/kdenlivejM2861.westley" , "/home/mcfrisk/kdenlive/untitled.mp4" , () , ("f=mp4", "acodec=libmp3lame", "ab=128k", "ar=44100", "vcodec=mpeg4", "minrate=0", "b=400k", "aspect=@16/9", "mbd=2", "trellis=1", "mv4=1", "s=1280x720") , -1 , -1

Rendering of "/home/mcfrisk/kdenlive/untitled.mp4" finished

I newer see similar logs when rendering my large project. I think this is something else than a plain config mess.

Rendering the test project also fails to deinterlace 1080i and some of the pal-dv clips even when forced, but using original mts files instead of my manually converted mpeg4 avi's takes care of the double speed issue with 1080i clips.

Btw, loading my large project takes around 20 minutes! A lot of FUile infos are loaded slowly for each clip and kdenlive swaps like hell on this machine with only one gigabyte of memory. A quite a few crashes have happened, but nothing repeatable yet.

Two days ago I edited a video and when I tried to rendering everything went well.
But today I edited a new video, and I cant render it is saying that the streams contains no data. I'm so frustrated, and I dont know what to do.
I did nothing different...same camera, same program, same everything.
I tried to understand this up here, but honestly I cant =/
Really need help, I'm going crazy!

what type of input files?

What vers of kdenlive?
