  • How to wmv video file in alfresco

    14 mai 2014, par sameer

    I am using Media Viewer add on to preview documents. For video files I am using FFMPEG as described in Media Viewer configuration page. It is able to convert for .avi files. But when I preview .wmv file it says could not load thumbnail list and the page is stuck. When I reload all I get is black screen and only volume is audible no video is available.

  • Overlay two sequences of png's and turn them into a movie

    12 mai 2014, par Lau Llobet

    I’ve found how to turn a png sequence into a movie and I’ve found how to overlay two movies using transparency but I don’t know how to do both things at once (using png’s transparency).

    The bottom layer of png’s is smaller than the top one and needs to be stretched to a certain resolution and also have a padding to be centered.

    The output doesn’t have to have alpha (black for alpha is ok). I’m a bit confused by the abundance of filter options.

    For the moment I’ve found :

    ./ffmpeg -i ./seq1/%d.bmp -vf "movie=./%d.png [a]; [in][a] overlay=0:366" combined.m2v

    It works, now I’ve got to find the padding and resize things
