Hello, I have been using mpeg4ip 0.9.9 to generate ISO compliant MPEG-4 files. I first run them with xvidenc to get an ISO compliant video stream, then mp4creator to encapsulate the video in a 'mov' compatible MPEG-4. All files created play using 'mp4player' (part of mpeg4ip). Files generated without using the 'use64bits' option of mp4ceator can be played by mplayer. But files generated using the 'use64bits' option of mp4creator can not be played (even for files under 4GB). mplayer returns with: ----------------------------------------

(End of file) ---------------------------------------- It seems that mplayer do not handle 64bits pointers : "Warning! pts=6744000 length=-1145716310" ? Note that I compiled mplayer with '--enable-largefiles' (enable support for files > 2 GBytes) and that this behavior happens on 'use64bits' files of under 2GB as well (tried on a 200MB generated file). -- Martial MICHEL, PhD Computer Scientist, National Institute of Standards and Technology SmartSpace Project: http://www.nist.gov/smartspace/ E-mail: martial.michel@nist.gov / Phone: (+1) 301 975 3866
