I want to output a video of gource, I follow this guide Creating videos with gource but I get error on video codec. I also use this guide enable libx264 support on

This is my error :

gource -o - | ffmpeg -y -b 3000K -r 60 -f image2pipe -vcodec ppm -i - -vcodec libx264 -vpre slow -threads 0 gource.mp4

pipe:: could not find codec parameters

I think I finally fixed this problem for me by installing the following packages (you probably don't need all of them):

libnetpbm10-dev (2:10.0-12.2)

libavfilter1 (4:0.6.2-1ubuntu1.1) libavformat52 (4:0.6.2-1ubuntu1.1) libpostproc51 (4:0.6.2-1ubuntu1.1) libswscale0 (4:0.6.2-1ubuntu1.1)

libavcodec-extra-52 (4:0.6.2-1ubuntu2) libavutil-extra-50 (4:0.6.2-1ubuntu2)

The complete error I got to start with:

[image2pipe @ 0x23036e0]Could not find codec parameters (Video: ppm)
[image2pipe @ 0x23036e0]Estimating duration from bitrate, this may be inaccurate
pipe:: could not find codec parameters
