I'm not sure I understand what you mean. :) Some output: If I run the new jpeg2yuv I get this: [EMAIL PROTECTED] sam]$ jpeg2yuv -v 2 -n 1 -f 25 -I p -j snap-000000.jpg >frame.yuv INFO: [jpeg2yuv] Wp1 INFO: [jpeg2yuv] Parsing char v INFO: [jpeg2yuv] Parsing char n INFO: [jpeg2yuv] Parsing char f INFO: [jpeg2yuv] Parsing char I INFO: [jpeg2yuv] Parsing char j INFO: [jpeg2yuv] Parsing & checking input files. --DEBUG: [jpeg2yuv] Analyzing snap-000000.jpg to get the right pic params INFO: [jpeg2yuv] YUV colorspace detected.

With the old jpeg2yuv, I get this: [EMAIL PROTECTED] sam]$ 160jpeg2yuv -v 2 -n 1 -f 25 -I p -j snap-000000.jpg >frame.yuv INFO: [160jpeg2yuv] Parsing & checking input files. --DEBUG: [160jpeg2yuv] Analyzing snap-000000.jpg to get the right pic params INFO: [160jpeg2yuv] Image dimensions are 320x240 INFO: [160jpeg2yuv] Movie frame rate is: 25.000000 frames/second INFO: [160jpeg2yuv] Non-interlaced/progressive frames.

And then it exits, with one yuv frame in the resulting file. With -n 0: [EMAIL PROTECTED] sam]$ jpeg2yuv -v 2 -n 0 -f 25 -I p -j snap-000000.jpg >frame.yuv INFO: [jpeg2yuv] Wp1 INFO: [jpeg2yuv] Parsing char v INFO: [jpeg2yuv] Parsing char n INFO: [jpeg2yuv] Parsing char f INFO: [jpeg2yuv] Parsing char I INFO: [jpeg2yuv] Parsing char j INFO: [jpeg2yuv] Parsing & checking input files. --DEBUG: [jpeg2yuv] Analyzing snap-000000.jpg to get the right pic params INFO: [jpeg2yuv] YUV colorspace detected.

It feels like there's been a change in an exit condition somewhere, as: [EMAIL PROTECTED] sam]$ 160jpeg2yuv -v 2 -n 0 -f 25 -I p -j snap-000000.jpg >frame.yuv INFO: [160jpeg2yuv] Parsing & checking input files. --DEBUG: [160jpeg2yuv] Analyzing snap-000000.jpg to get the right pic params INFO: [160jpeg2yuv] Image dimensions are 320x240 INFO: [160jpeg2yuv] Movie frame rate is: 25.000000 frames/second INFO: [160jpeg2yuv] Non-interlaced/progressive frames.

With -n set to -1, both versions will write that single frame to the output file forever. /Sam ------------------------------------------------------- This SF.net email is sponsored by: VM Ware With VMware you can run multiple operating systems on a single machine.
