Video generate thumbnail called on non-existent video.

Video generate thumbnail called on non-existent video.

Hi @reagle ,
from the trace you put in #53, it seems that the thumbnail for the video is not generated. I would guess that some option is not compatible with avconv, if you can check manually ?
For easier debugging you can use the -n to use only one cpu, then the pool is not used:

sigal build -fd -n 1

Can you paste the output ?

Thanks, it confirms that there is an issue with the call to avconv. I will check how to trace back the errors from the call to subprocess, but I can't test with avconv.
Can you try this manually ?

cd /home/reagle/f/photo/_build/
# check that 09-1315-nora-snow.webm exists
ffmpeg -i 09-1315-nora-snow.webm -an -r 1-vframes 1 -y thumbnails/09-1315-nora-snow.jpg.tmp.jpg

[reagle]

Sorry, 09-1315-nora-snow.webm didn't exist because of a unsupported argument I was passing in webm_options (apparently -c:a libvo_aacenc is no good on Debian/Ubuntu.) Thanks for your help!
