Hmmm, interesting. not really, it just says that: pts computed from wrapper can only fit in a timeBase 50 (aka 50 fields, aka interlaced broadcast) but contents is 25fps (ffmpeg output is not so clear ;-)) >> INFO: [y4mstabilizer] frame rate: 25/1 fps (~25.000000) >> INFO: [y4mstabilizer] interlace: top-field-first >> INFO: [y4mstabilizer] sample aspect ratio: 16:15 one tip to Richard: if your contents is interlaced, deinterlace (from ffmpeg or another mjpeg tool) if your contents is progressive (and only the wrapper is interlaced), correct headers with yuvcorrect …your stream is still written as interlaced when it reaches y4mstabilizer I had some crashes too with y4mstabilizer (official 190 and previous RC), a file crashed after 7 minutes (was only for tests purposes, but it's a great tool, with a great result :-)) I'm on MacOsX If somebody is interested, I can try to reproduce it (was "old", I must try to remember "how to" :-D) and send crash log bye Hervé ------------------------------------------------------------------------------ OpenSolaris 2009.06 is a cutting edge operating system for enterprises looking to deploy the next generation of Solaris that includes the latest innovations from Sun and the OpenSource community.
