Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: pix_film (gmerlin) crashes with animated gifs

Initial Comment: when trying to open an animated gif (as attached) with [pix_film], Gem crashes.

the problem might be within gmerlin-avdecoder:

Message: i checked with gmerlin-avdecoder upstream, and indeed it was missing "seeking" for animated gifs.

i submitted a fix for the problem, which (once it's accepted) will magically make animated gifs work properly in Gem.

i think i can therefore close this ticket.

Message: indeed there was a problem in Gem. unfortunately gifs still cannot be played in random access mode. (and in threaded decoding they usually will be decoded before all the frames have been displayed)

Message: but then: gmerlin_play does _not_ crash on the same file.
