Ubuntu 15.04 - Blank/Transparent Gif

[albertossilva]

When I use silencast, all images and the gif get blank/transparent

Blank images and gif

I have been experiencing this bug myself, but have so far been unable to determine if it is a bug with avconv/ffmpeg or the way silentcast uses it.

Can you check if v2.1 solves this problem?

[Seth-Johnson]

v2.1 seems to work on my end, although I don't know why, temptoanim hasn't been touched by any of the recent changes.. @albertossilva what version of avconv do you have installed? Check by running avconv -version please. On my 15.04 box I have:

seth@tanager:~/Downloads/silentcast-2.1$ avconv -version

A friend of mine was unable to reproduce on 14.04 as well, running Silentcast 2.0 with avconv version:

$ avconv -version 
avconv version 9.18-6:9.18-0ubuntu0.14.04.1, Copyright (c) 2000-2014 the Libav developers

libavresample 1. 0. 1 / 1. 0. 1 
libswscale 2. 1. 1 / 2. 1. 1  

At this point I am unsure how to proceed, as I am unable to reproduce the issue any longer.

I think this is resolved with v2.4
