[PD] Gem - loading UT or Magicyuv Codec (Debian/Linux)

[oliver]

Hi,

I recently tried to load some video clips encoded with either a "UT" or 
"magicyuv" Codec, that play fine on any other video software i use 
(mplayer, mpv, vlc, kdenlive etc.)

Loading one of these immediately causes PD/Gem to quit.

Running PD from the commandline with "-d 4" i only get this error 
message on the console:

===========================================
Pixelformat not specified for video frame
Pd: signal 6
===========================================

In the PD terminal window, i get (before quitting):

GEM: compiled for MMX/SSE2 architecture
GEM: using SSE2 optimization
GEM: detected 4 CPUs
GEM: image loading plugins: magick STB
GEM: film loading plugins: gmerlin quicktime4linux
GEM: image saving plugins: STB magick
GEM: model loading plugins: ASSIMP3 OBJ
GEM: video record plugins: QT4L V4L2
GEM: video capture plugins: decklink v4l2

[pix_film]: gmerlin support
[pix_film]: quicktime4linux support
[pix_film]: image support


These are my specs:

Debian 4.19.98-1+deb10u1 (2020-04-27)
PD: 0.50.2
GEM: ver: 0.94. "Debian/1:0.94-1"


Thanks for any hints

Oliver
