We’ve changed some marginal parts – such as the QPoffset – but haven’t dealt with the reference pictures nor the ref idcs. Up until now we’ve just used pre-made configuration files that have this part set up already. To understand what’s causing the slow seeking we first have to look at and understand how the declared GOPs work in an hevc stream. So, before we go further with tinkering we first need to figure out what’s causing this problem and a means to fix it – because any hevc encode that you can’t skip around in is as good as useless. I would assume it’s equally slow with libav smarter fork because that’s what Osmo4’s decoder is based off of.

What we have found, though, is a recurring problem in our test files – seeking is atrociously slow with all three of the tested decoders I have available. We’ve tinkered a bit, but haven’t really found the super settings that are the holy grail of hobbyist video encoding. That said, here they are:ībb_sunflower_1080p_60fps_stereo_arcd.mp4ībb_sunflower_1080p_60fps_stereo_arcc.mp4ībb_sunflower_1080p_60fps_stereo_agmh.mp4ībb_sunflower_1080p_30fps_stereo_arcd.mp4ībb_sunflower_1080p_30fps_stereo_arcc.mp4ībb_sunflower_1080p_30fps_stereo_agmh.Alright, now we’ve done our fair share of encoding with TAppEncoder and should have a good grasp of the basics. If the respective owners of these properties request that I take these mirrors down, I will do so. These properties belong to their respective owners. I do not own any of these nor do I claim ownership of any of these.

So far I have the following (will be updated as the downloads and uploads complete) As of this is all of the files from a combination of and. I've made it my mission to download them all and post them. As many of you likely know the Big Buck Bunny downloads are extremely slow.
