Survey: use of OggTheora writer to save animations

Does anyone use the OggTheora animation writer in ParaView? We are pondering deprecating the writer if it isn’t useful to anyone.

I use it / have used it – though primarily recently when using nightly / RC builds of ParaView in client-server mode where it seemed only the .ogv format worked (saving to MP4 / AVI would cause segfaults).

Definitely not my first choice of format (mostly due to unfamiliarity), but it does play in VLC and Handbrake is able to convert it to other formats.

No, no one here uses it that I know of. I would be in favor of deprecating the OggTheora writer. It just causes confusion.

Thanks for the feedback. That’s all fixed now in 5.12.0.

@cory.quammen – I tried to save an MP4 today and got these output messages:

It seems to have worked, it saved an MP4 file and it’s valid. But errors / messages like these keep pushing me back to the OGV file. Note that I’m running in server-client mode, not sure if that’s the reason…

Hi @GregVernon thanks for the report. Will take a look.
