Hello everyone, I am using pix_record to encode files in codec 23 and I cannot get a filesize bigger than 4294967295 bytes or 4.29 GB. The files by the way are unusable after this size and they just won't play in regular video players.
Can some one explain why this happens and if there is a workaround?
Again, recent Gem and Pd on ubuntu 12.04.
best,
Jaime
If this is of any help, this happens at around 14000 frames or 7 minutes and 45 seconds... J

what is codec "23"? [codeclist( will enumerate the codecs installed on your system. the ID might change between systems.
cannot get a filesize bigger than 4294967295 bytes or 4.29 GB. The files by
looks like a 4GB file size limitiation. probably a bug in libquicktime. i cannot remember whether there's a small lqt tool that allows recording of a stream, so you could test whether the bug is actually there.

raw RGB uncompressed.

I am not sure what you are suggesting: Should I find this tool and check if it happens with it as well?

that would help (if such a tool exists). alternatively, one could check one of the applications at [1].

and just to be sure: can these files be played with Gem? can they be played with lqtplay? does Gem stop recording, once the filesize is that big?

i just ran a "quick" test recording 17245 frames of a 256x256 video with "raw" codec, which results in a 4520880968 bytes file
it plays nicely with qtplay, mplayer (well, colors are wrong here) and gstreamer (using "gst-launch filesrc location=mymovie.mov ! decodebin ! ffmpegcolorspace ! xvimagesink"). it doesn't play with vlc (complaining about missing codec "twos") though.
