[xine-devel] using external plugins

[Florin A. <fl...@an...>]

(forwarding it to xine-devel, per Guenter's suggestion)

I see xine progressing nicely recently. The Mozilla plugin, the Real and
QT stuff... Good work.

Here's a weird idea:
Is it possible to make xine use I/O modules and filter plugins from
transcode?

http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/

The list of transcode plugins and filters is impressive:

[florin@rivendell florin]$ cd /usr/lib/transcode; ls *.so
a52_decore.so       filter_astat.so         filter_yuvmedian.so
af6_decore.so       filter_clone.so         filter_yuy2toyv12.so
export_divx4raw.so  filter_cshift.so        import_ac3.so
export_divx4.so     filter_cut.so           import_avi.so
export_divx5raw.so  filter_decimate.so      import_divx.so
export_divx5.so     filter_dilyuvmmx.so     import_dvd.so
export_dvraw.so     filter_divxkey.so       import_dv.so
export_dv.so        filter_dnr.so           import_ffmpeg.so
export_ffmpeg.so    filter_extsub2.so       import_lav.so
export_jpg.so       filter_extsub.so        import_lzo.so
export_lame.so      filter_fields.so        import_mp3.so
export_lzo.so       filter_invert.so        import_mpeg2.so
export_mjpeg.so     filter_ivtc.so          import_mplayer.so
export_mp2enc.so    filter_mask.so          import_net.so
export_mpeg2enc.so  filter_normalize.so     import_null.so
export_mpeg.so      filter_null.so          import_nuv.so
export_net.so       filter_preview.so       import_nvrec.so
export_null.so      filter_pv.so            import_ogg.so
export_ogg.so       filter_resample.so      import_rawlist.so
export_pcm.so       filter_skip.so          import_raw.so
export_ppm.so       filter_smartdeinter.so  import_v4l.so
export_raw.so       filter_smooth.so        import_vdrac3.so
export_sampeg.so    filter_subtitler.so     import_vob.so
export_toolame.so   filter_tc_audio.so      import_xml.so
export_wav.so       filter_tc_video.so      import_xvid.so
export_yuv4mpeg.so  filter_testframe.so     import_yuv4mpeg.so
filter_29to23.so    filter_test.so          import_yuv.so
filter_32detect.so  filter_videocore.so     libioaux.so
filter_32drop.so    filter_xsharpen.so
filter_aclip.so     filter_yuvdenoise.so
[florin@rivendell transcode]$

All that stuff is already there, the license is compatible with Free
Software, and it's doing a great job.

Creating an interface to the transcode plugins and filters (if at all
possible) might trigger a feed-back effect that might help both projects
at the same time - but you're familiar with the "economics" of the open
source software, so i won't preach to the choir. :-)

Or, if not the I/O modules, then at least use the filters.

Now that xine gets into the "business" of _processing_ video, using
transcode stuff would be a quick and easy way to achieve _a_lot_ of
functionality in a very short time.

Also, since xine has post-processing capabilities as a player, it would
be an easy way to do stuff like deinterlace-while-playing,
denoise-while-playing, sharpen-while-playing and stuff like that.
Especially the deinterlace thing, that one would be great to have.

Perhaps both projects could reach an agreement upon a common
filter/plugin API, or something like that.

I'm not sure what are your plans, or how easy it is to do it, but it
just seems to me like a good idea. Of course, i could be wrong. :-)

Anyways, have fun!
