Comment 2 Edward Hervey 2006-02-12 13:33:08 UTC

it's video codec is video codec: Palettized 8-bit RGB,

The following command line works : 
gst-launch-0.10 -v -t filesrc location=fencounters.avi ! decodebin ! ffmpegcolorspace ! xvimagesink

Comment 3 Tim-Philipp Müller 2006-02-13 11:56:40 UTC

The above pipeline works for me too, but when played with playbin I get glibc assertion failures. It's usually one of two:

Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: audioclock2
*** glibc detected *** free(): invalid next size (normal): 0x08285278 ***

Program received signal SIGABRT, Aborted.

valgrind isn't much use here either.

Christian, are you getting the same as I do, or something different?

Comment 4 Luca Ognibene 2006-02-21 22:40:06 UTC

I get the same debug as Tim. 
I can replicate the bug also using:
  filesrc ! avidemux ! ffmpegcolorspace ! videoscale ! fakesink
or
  filesrc ! avidemux ! ffmpegcolorspace ! videobox ! fakesink

(demuxer -> colorspace -> child of basetransform -> sink)

Comment 6 Tim-Philipp Müller 2006-02-24 14:01:43 UTC

This should fix it again:

2006-02-24  Tim-Philipp Müller  <tim at centricular dot net>

       * gst/ffmpegcolorspace/gstffmpegcolorspace.c:
       (gst_ffmpegcsp_caps_remove_format_info),
       (gst_ffmpegcsp_get_unit_size):
         The 'palette_data' field from incoming RGB caps shouldn't be
         proxied on outgoing YUV caps; also, restrict unit size
         adjustment in case of paletted data only to the unit that
         actually has a palette. Fixes #330711.
