mediadownload (for pv2s and saturns on linux)
collaboration from anewguy, saturnnights and myself have created a new app for both pv2s and saturn camcorders. Works very similar to avidownload for the camcorders and for the pv2s it records the pictures to a pv2_pics folder in your /home folder. requires all of the normals (libusb) as well as imagemagick in order for the raw files to be converted to .jpgs http://jeff.crowell.googlepages.com/mediadownload.tar.gz

well, just got to -*test*-('")ing it on PPC, works fine with the saturn, but I had errors with a PV2 ibook:/home/jeff/mediadownload/src# ./mediadownload INFO: Closing any opened devices...

well, i put some work into avidownload making sure everything was endian-neutral, so all would work sound. i never looked at the pv2's code, and it wasn't developed with anything but intel x86 in mind, so i think that might be the problem. the only people that would know for sure would be the original devs of pv2tool.

tried it with a bunch of other pv2s, no joy. is ygfperson the orig. developer?

Where is the ".ppm" file suffix being introduced? It seems to me, when I was working on the non-JPG version of all of this, that the file type was ".raw". If the ".ppm" was introduced as part of the JPEG conversion stuff, I would suggest looking there. As far as I can remember, from the people who did -*test*-('") the version I had out last prior to the addition of JPEG conversion, the program was working well. That's why I would think you should look there - I suspect the file name is being corrupted from .raw to .ppm, but it's been a while and I haven't paid any attention since the non-JPEG version I developed from pv2tool and SaturnNights' avidownload has been working great for me in Ubuntu. EDIT: just download your tar and have been looking in the source. In camera_download.c you have added a system call to convert all .ppm to .jpg, yet you haven't let the code actually download any pictures yet. I think you will need to check the functions in this section of code to see what you've hacked. Also, IF I remember correctly (beleieve me, a mind is a terrible thing to waste and I "wasted" mine when I was younger so my memory isn't the best!), I think I took avidownload and pv2tools for Linux to make the meld, looking at the windows version of pv2tools when needed for some clarification. Don't know if that helps or not. EDIT-EDIT: I think it would be best to also offer the original that just outputs the .raw images and let people be able to work with that. The code is much smaller, and many of the image processors can load in a raw image. In this manner, until you fix your JPEG conversion stuff, there will be a working version available. Also, try your "failed" cameras on the pre-JPEG conversion program and see if they work there or not, then post the results back here. Should help you troubleshoot where the error is being introduced. Remember the camera must have at least 1 picture on it or the run is probably either going to say no pictures found or abort on some silly error - I never checked that yet. EDIT-EDIT-EDIT: Look at the terminal output you posted - it appears the process ran as it was supposed to. You apparently had no .ppm image in the date/time folder, so your external "convert" process is letting you know there is nothing to convert. The rest of the code is telling you 2 things: 1. The key it used to unlock has no been found before. I left the code in that says to post it since originally that's what was happening - posting working codes. I'm not sure if that is allowed now or not. 2. There are no images on the camera to download. I would make the following suggestion to you: wait until the pictures download, then, and only then, if the count if pictures is greater than zero, do your call to "convert". Otherwise you are accomplishing nothing.

i would really rather it if you allowed straight output to .raws with a command line switch. i do a lot of preprocessing in gimp before exportation, so i'd like the images before jpeg artifaction.

Enigma: If you're working with an Apple PPC, let me know. I know the code the got melded together, especially that of pvtools, did look at endian vs none. The thing I'm not sure of, and a quick review of the code by you would note it, is whether I took out the "#ifdef" in the headers, etc., where it was checking for Windows versus Linux. If so, you could probably add that back in and try to compile again on the ppc to see if it would work. I have the source here for what I did and will check it later. I know the LSB/MSB stuff gets confusing to some.

saturnnights/anewguy: sorry, I haven't had much time to check around here as of late. 1.) I will add a switch to allow jpg conversion. (eta: this weekend, tomorrow is my birthday, and fridays I usually dont do any coding) 2.) IIRC I made two calls to convert to PPM, the first always fails, becauase I put it in too early, When I made the second call for PPM, I left the first one in. Lazyness rears its ugly head. My iBook has been under my ever growing pile of homework that I fail to complete (2 thesis papers due really soon :() The problem is reading the FAT. I'll check for any issues, I'll try a different distro, because my dist-upgrade did give me some weird errors. anything else?

Any chance there's a newer version?

I'd try getting the version without ANY conversions in it - just the basic download and output of either the video or of raw images. As SaturnNights and myself have said, in the long run it is far better to leave any image processing external to the downloading process. We prefer the raw downloads and using another program to process the raw images afterwards. If you need a copy of source for just downloading and outputting raw images without the conversions let me know and I'll see if I still have the source. I did convert it all to be windowed using GTK in Linux if you want to try that source as well (requires GTK development libraries). Dave

--waves to anewguy-- hey, i'm alive! i've got a couple of projects running at same time, but i haven't forgotten you. i'm sorry about the ball drop on my side.
