--- Comment #11 from Oleksij Rempel <bug-track at fisher-privat.net> ---
caps are sort of different:
/GstPipeline:pipeline0/GstMpeg2dec:mpeg2dec0.GstPad:src: caps = "video/x-raw\,\
format\=\(string\)I420\,\ width\=\(int\)720\,\ height\=\(int\)576\,\
pixel-aspect-ratio\=\(fraction\)256/135\,\ interlace-mode\=\(string\)mixed\,\
chroma-site\=\(string\)mpeg2\,\ colorimetry\=\(string\)2:4:8:3\,\
framerate\=\(fraction\)25/1"

vs

/GstPipeline:pipeline0/GstMpeg2dec:mpeg2dec0.GstPad:src: caps = "video/x-raw\,\
format\=\(string\)I420\,\ width\=\(int\)720\,\ height\=\(int\)576\,\
pixel-aspect-ratio\=\(fraction\)256/135\,\ interlace-mode\=\(string\)mixed\,\
chroma-site\=\(string\)mpeg2\,\ colorimetry\=\(string\)2:4:5:4\,\
framerate\=\(fraction\)25/1"

The only difference is colorimetry\=\(string\)2:4:5:4.
hm.. what is the best way to solve it? I think about some variants:
- don't reinit on caps which we don't support.
- don't reinit on multipass mode
- use counter for files suffix for each reinit: multipass.cache.0 ...
multipass.cache.2 and so on
- other ideas?
