The last piece in the puzzle for doing hardware conversions automatically is ensuring we only consider valid target formats for the conversion. Although it is unintuitive, some vaapi drivers can expose a different set of formats for uploads vs for conversions, and that is the case on the Intel hardware I have here. Before this change, we would use the upload target list, and our selection algorithm would pick a format that doesn't work for conversions, causing everything to fail. Whoops. Successfully obtaining the conversion target format list is a bit of a convoluted process, with only parts of it encapsulated by ffmpeg. Specifically, ffmpeg understands the concept of hardware configurations that can affect the constraints of a device, but does not define what configurations are - that is left up to the specific hwdevice type. In the case of vaapi, we need to create a config for the video processing endpoint, and use that when querying for constraints. I decided to encapsulate creation of the config as part of the hwdec init process, so that the constraint query can be down in the hwtransfer code in an opaque way. I don't know if any other hardware will need this capability, but if so, we'll be able to account for it. Then, when we look at probing, instead of checking for what formats are supported for transfers, we use the results of the constraint query with the conversion config. And as that config doesn't depend on the source format, we only need to do it once. |
