Re: [GEM-dev] video with alpha in Gem?

yes, i figured out, alpha is not working with gem_filmQT4L.so. i tried Gmerlin. remember that some time ago it was segfaulting in Gem, when loading video, but later i was using gmerlin with mjpeg without any problems. gmerlin is still working with mjpeg, but this with pnga is segfaulting, then loading video. i tested more machines with same gmerlin-avdec, Gem, kernel, but Pd version differs having different behaviour. gmerlin-avdecoder 1.2.0-2 GEM: ver: 0.93.git 374f713 Pd 0.45.0test kernel 3.9.3-1-ARCH gdb backtrace: Starting program: /usr/bin/pd -lib Gem -nosound /usr/lib/pd/extra/Gem/examples/04.pix/05.film.pd warning: no loadable sections found in added symbol-file system-supplied DSO at 0x7ffff7ffa000 warning: Could not load shared library symbols for linux-vdso.so.1.

hallo, i tried to play rgba video with alpha in gem. IOhannes proposed PNGA video, so i got one using 'ffmpeg -i %4d.png -vcodec png rgba_png.mov||' you can find it here (13Mb): http://kubriel.servus.at/uploads/rgba_png.avi i tested [pix_film] enabling alpha with [alpha] without succes, background is not transparent. i tested video in resolume with nice transparent background result.

[pix_buffer] crash Pd on Windows
by Jack 05 May '13

05 May '13

Hello, [pix_buffer] seems to crash Pd with Windows when the number of image loaded by [pix_buffer_write] is > 2412. I tested this with four configurations : A MSI with 8 Go of RAM and Windows 8 (64 bits) Pd-extended 0.43.4 A MacPro with 3 Go of RAM and Windows 7 (32 bits) Pd-extended 0.43.4 A MSI with 8 Go of RAM and Ubuntu13.04 (64 bits) Pd 0.44.3 (with Gem ver: 0.93.git 374f713) A MacBookPro MacOSX.6 Pd-extended 0.43.4 All works fine under MacBookPro with MacOSX and MSI with Ubuntu, but pd crash on Windows when the number of image loaded by [pix_buffer_write] is > 2412. The patch contains a [pix_buffer test 10000]. If i create and send the message [allocate 640 480 4( to this [pix_buffer test 10000], on Windows i get in the console 'out of memory!', this is not the case under Ubuntu (not tested under MacOSX). I just want to use the abstraction [pix_buffer_filmopen] which use [pix_buffer] under Windows but it is impossible with a (not so) long movie (around 7200 frames, .mov, codec photoJPEG)... This movie is read fine until the end with [pix_film] under Windows. If someone can help me to solve this problem, it would be very nice. Thanx. ++ Jack
