h264 movie out only works once

I can’t get h264 encoding on the movie out TOP working consistently. If I create a new .toe and add a Movie Out TOP it will export a single h264 video and on subsequent attempts to record it gives the error message: “Error: unable to open video codec (2)” and won’t encode any more videos. It doesn’t seem to matter if I change the filename or not. This is in build 51780 comm license. Thanks

card is Titan Z

Hey James, can you tell me the GPU driver version you are on?

350.12

updated to 353.30 and seeing the same issue

I’m seeing this on 23120 when trying to use H.265, MPEG-4, and H.264.

Nvidia 398.11, on a 1070 notebook.

What’s the error you see when you do MPEG 4 Part 2? That one doesn’t use the GPU at all, strange it would fail.

Also seeing this on 23470.

Malcolm - I think the MPEG-4 report was erroneous. Sorry - that one is working.

So it only works once, then fails from then on? What happens if you try H264 once then H265 next?

Oddly it now appears that H.264 is working fine but H.265 is throwing the error consistently.

This is after trying H.264 first (without restarting TD, just waking the machine from sleep with a toe open).

OK - new .toe, H.264 first codec I tried, got the error.

Now getting consistently with H.264 again.
