Hi,

I was trying to finish Tonight my project, which I started about 6 weeks ago, and... rendering crashed (I was using kdenlive for couple of months before and had never such problem). I realized this problem is ONLY for H.264, I was trying few other options eg. MPEG-2, MPEG-4 and everything was fine, just problem with H.264. I have such message bellow:

Rendering of /mnt/.../012.mp4 crashed

consumer_avformat.c: Unable to encode audio - disabling audio output.
[mp4 @ 0x2030c30] track 1: codec frame size is not set

I use:
kdenlive 0.8.2.1
mlt 0.7.6
ffmpeg 0.10

Any ideas?

p.s. Another strange thing - I used to have (but not anymore) a option for rendering - HuffYUV lossless (video) + PCM (sound). Now, this option is unaviable and as a error is wrote: Unsupported audio codec: pcm_s16le

Thanks for any help

In my case sollution was downgrading ffmpeg from 0.10 to 0.7.8 ...

I was trying a new ffmpeg 0.10.2 (relase in March), but still the same problem. Looks like kdenlive doesn't like a new ffmpeg :(

In my case a new MLT 0.8.0 solved the problem :)
