Re: [Paraview] headless configuration and intel ospray

2018-05-16 Thread David E DeMarle 
Unfortunately no you still need a GL (osmesa or EGL for headless).

File a feature request on the gitlab issue tracker if you want to attract
attention to that capability. It probably isn't that hard to do and it
would be a good use case.

The VLC player will also play .avi's created from 5.4.1, on all platforms.

If you happen to be on macOS AND you happen to still have a license for 
Quicktime 7 Pro, that will also create a movie from the images. You can export 
in whatever format that Quicktime supports.

Francesco,

There was a known bug/feature in the .avi writer in ParaView 5.4.1, where 
it wrote a version of .avi that was not compatible with the OS X Quicktime 
player (the OS X default) and the Windows Media player.  This has been 
corrected in ParaView 5.5.0.  (I just tested them on my MacBook.)

ParaView used to also be able to save animations as MJPEG AVI
(.avi) files.

Unfortunately, the version currently in Debian GNU/Linux (unstable and
testing) seems to have a regression and is unable to save .avi files.
See my [bug report](https://bugs.debian.org/892293) on the Debian BTS...

My current workaround is:

 → save animations as PNG images

 → convert them with

   $ ffmpeg -f image2 -framerate 5 -i input.%04d.png \
-vcodec mjpeg -pix_fmt yuv420p -q:v 3 output.avi


Please note that ParaView used to save .avi files with pixel format
yuvj422p (until it stopped doing so, because of the above mentioned
regression), but I started to use pixel format yuv420p, to work around
a [bug](https://bugs.debian.org/863663) in GStreamer.
With this pixel format the animation may be correctly played by
GStreamer on GNU/Linux and hence, when embedded in a PDF page, by
pdf-presenter-console on GNU/Linux, as well as by Acrobat Reader DC on
Windows...

If anyone knows any better strategy, comments are welcome!

Re: [Paraview] [EXTERNAL] Re: pvtm file format

No problem. We got where we needed to be eventually -- it would  have gone
faster if I didn't "remember" that the .pvtm isn't a proper VTK file
extension :)
