Category: None Group: None >Status: Pending Priority: 5 Private: No Submitted By: ClaudiusMaximus (claudiusmaximus) Assigned to: Nobody/Anonymous (nobody) Summary: pix_write to a PPM stream Initial Comment: I would very much like if pix_write could write successive frames to a PPM stream. This would let me to do things like: mkfifo stream.ppm && pd -nogui -lib Gem -open my-rendering-patch.pd & cat stream.ppm | ppmtoy4m ... | y4mscaler ... | mpeg2enc ... At the moment I'm rendering to multiple TIFF files, which takes a vast amount of temporary disk space, and is more complicated to encode later. ---------------------------------------------------------------------- >Comment By: IOhannes m zmlnig (zmoelnig) Date: 2010-07-14 19:48 Message: i have added an experimental support for writing to v4l1-loopback devices to the [pix_record] class. unfortunately, [pix_record] (and the record-backends) are badly designed right now, i guess they need a major overhaul. in the meantime: - install vloopback kernel-module - get latest Gem (svn) - build, cd to src/plugins/recordV4L/ and run "autoreconf -fiv && ./configure && make" - copy the resulting ./libs/gem_recordV4L.so besides the Gem.pd_linux - make sure you have no other gem_record* lying besides Gem.pd_linux - start pd/Gem - create [pix_record] - use [file /dev/video1, record 1( (or whatever your vloopback-write device is) - then you should be able to access the output of pix_record via /dev/video2 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507082&aid=1901418&group_id=64325 _______________________________________________ GEM-dev mailing list [email protected] http://lists.puredata.info/listinfo/gem-dev
