--- Comment #10 from Nicola <lists at svrinformatica.it> ---
after applying the patch to avidemux, these pipeline work:

filesrc ! avidemux ! fakesink
filesrc ! avidemux ! avdec_h264 ! xvimagesink

this one does not work

filesrc ! avidemux ! h264parse ! fakesink

h264parse fails with this error:

h264parse gsth264parse.c:2672:gst_h264_parse_set_caps:<h264parse0> wrong avcC
version

so h264 contained in this file can be handled by ffmpeg but is not handled in
h264parse,

the ideal solution would be to properly handle this format in h264parse too, a
temporary solution could be to let h264parse work in passthrough mode when it
does not recognize the h264 stream and no conversion (avc-> byte stream ecc..)
is required
