Arch Linux

Description:
A few days ago, converting ppm streams from 'gource' to mp4 worked just fine.
The command I used was

gource -1200x720 --key --camera-mode overview --highlight-all-users --file-idle-time 0 -auto-skip-seconds 0.001 --seconds-per-day 0.5 --hide progress,mouse --stop-at-end --max-files 99999999999 --max-file-lag 0.00001 --output-ppm-stream - | ffmpeg -f image2pipe -vcodec ppm -i - -y -vcodec libx264 -threads 4 -b 3000k -maxrate 8000k -bufsize 10000k video.mp4

When I do the same now (I had to replace -b with -b:v because ffmpeg complained):


gource -1200x720 --key --camera-mode overview --highlight-all-users --file-idle-time 0 -auto-skip-seconds 0.001 --seconds-per-day 0.5 --hide progress,mouse --stop-at-end --max-files 99999999999 --max-file-lag 0.00001 --output-ppm-stream - | ffmpeg -f image2pipe -vcodec ppm -i - -y -vcodec libx264 -threads 4 -b:v 3000k -maxrate 8000k -bufsize 10000k video.mp4

, ffmpeg gets me this output:

and the video just appears to be completely green watched with vlc player.

When I watch the video using mplayer, the video is not just a green screen, but the colors of things are wrong.
