[ANN] SqueakMovieMorph (Alpha) plays any video file playable by QuickTime
by DeNigris Sean 30 Dec '10

30 Dec '10

Installation: Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFFI'; load. ((Smalltalk at: #ConfigurationOfFFI) project latestVersion) load. Gofer new squeaksource: 'SophieGoldDig'; package: 'SpdQT'; load. Then, blow your mind by playing a video in-image with: aURI := URI fromString: 'file:///path/to/video.ext'. movie := QuickTimeMovie openMovieFromURI: aURI. m := SqueakMovieMorph openOn: movie. Pharo 1.1.1 - there will be two errors – for both, go into the debugger and remove the isFinalizationSupported checks. See http://seandenigris.com/blog/?p=723 for details.

truncated output from Morph exportAsPNG
by Boyce,Edward 30 Dec '10

30 Dec '10

Hello all. I have an application where I need to export very long (but not very high) images -- around 800x50000 -- or so from a Morph of the same size. However, when I use any of the four Morph exportAs{PNG|BMP|JPEG|GIF} methods, the resulting files have their visual data truncated after about 10000 horizontal pixels. However, the overall image is still the full length -- just the output image data is missing from the "end" of the image, and the metadata for the image indicates that it is the length it is supposed to me. When the morph is viewed with inATwoWayScrollPane, all of the data is visible, so it is the export that is truncating data. An example of a truncated PNG is here: http://boycenet.net/ccam/m22_ko_w_contact_f26_1.png Does anyone know why this might be and what I might be able to do to output the full length of data? I've looked through the code and can't find any hard coded limits of 10000 pixels in the output. In case anyone is wondering, this output is a spectrogram of the vocalizations of a mouse that lacks a certain gene and thus makes it seem autistic, so it might be a model for autism in general, and the researcher is trying to analyze the voice patterns (at ultrasonic frequencies) over a long period of time (1 minute per sample from recordings taken at 196kHz sampling rate). So, yes, we are trying analyze mouse squeaks with Squeak! Thanks in advance for any insights.

Tropo
by James Robertson 30 Dec '10

30 Dec '10

Has anyone successfully tried out the Tropo interface? The install from here: http://www.squeaksource.com/Tropo.html went fine, but it didn't pull in the additional http encoding code it needs - and I don't really know what package has that. Any help would be appreciated; I've done a fair bit of work in JSON and network interfaces, and would like to pitch in on something like this.

Thanks for that rundown, John. It definitely uses GWorld. For sure: SophieQuickTimeMovieViaPlugin>>gWorldPtr SophieQuickTimeInterface>>setGWorldPtrOntoSurface:width:height:rowBytes:depth:movie: I guess you're saying that's somewhat different than the SurfacePlugin. Cool stuff. Chris
