User-submitted performance reports
In light of not really having a place for people to submit dav1d performance reports, here's an issue that people can reply to with their reports.
Please use the following template:
- hardware:
- software:
- dav1d revision:
- dav1d command line:
- input file:
- framerate:
- (optional) perf report:
You can get a perf report by installing the perf package and running dav1d like perf record ./dav1d .... Don't use framerate info from the same run though, as perf may slow things down a bit. You can then use perf report to get the relevant report information.

@jbk the progress for 8-bit content is outstanding indeed!
My next idea is to test the same video with different bitrates, but that takes some more time because I need encodes first. Any other tests that would be useful?
-
@EwoutH What is the CPU usage, when you get the 105fps? All cores are full?
-
@jbk Yes (screenshot). RAM usage between 310 and 320 MB.

Also tested a 32-bit build (8cef1efc) vs the same 64-bit build. Performance is about a quarter to a third on 8-bit content and about 20% lower on 10-bit content. Used commands and output.

@jbk It certainly looks like it. I used the same system (Core i7-4710MQ, Windows 10 64-bit) so the results should give a fair comparison between 32- and 64-bit builds. Shall I open a issue about the missing AVX-2 support?
No idea why, but in my tests I've seen no enhancements at all. I'm pasting the details below.

@EwoutH are you comparing to the last libaom? Because 1.0.0 is old.

Tested aomdec directly from aom master (without ffmpeg), results are a lot higher, especially with the Youtube video (Oliver 1080p). Now, dav1d is 77% faster on average (100% faster on average with only 8-bit content).

@EwoutH did you compile with LOW_BITDEPTH ?
CONFIG_LOWBITDEPTH=1 has been the default for a couple weeks: https://aomedia.googlesource.com/aom/+/4c118dc5e4765601e652612bbe9d1b9bdfb9e473
However, I see on the tracker that there have been some divergences between av1-normative and master, so there is a revert for that patch ready to merge: https://aomedia-review.googlesource.com/c/aom/+/74441
