3/31/2023 0 Comments Super transcoderThe nvcuvid resize option can be used when transcoding from one input to one output stream with different resolution (1:1 transcode). Two options exist for resizing on the GPU: using the nppscale filter or the nvcuvid resize option. Support for MPG, MTS and TS formats is available if running Mac OS X 10.11 El Capitan. It supports the transcoding of MP4 and MOV files encoded using Apple ProRes 422, 444 and H.264 codecs. The benchmark loads one image per frame until the app runs out of memory and is stopped. Transcoding often involves not only changing format or bitrate of the input stream, but also resizing it. Super Transcoder is a simple video transcoding tool that is surprisingly fast. Let's look at the memory consumption on an iPhone 8. The transcoded images take up up to 8 times less memory and load an order of magnitudes faster. Transcoded to BC7 RGBA occupying 1 MB per image.Transcoded to BC1 (DXT1) occupying 0.5 MB per image.In one of the following frames there's a lot of transcoding going on on the worker threads and while the frame time is too high, it's far from being as bad as with Jpeg/PNG. Only the actual GPU upload has to be done on the main thread. You can immediately see that the transcoding part is off-loaded to the worker threads (via the C# job system). Enhanced Voice Services (EVS) is a super-wideband speech audio codec developed by 3GPP and documented in TS 26.441. Let's load the same content from KTX 2.0 files with Basis Universal compression. Since the encoding of data determines the type of compression, as well as the bitrate and resolution of the video, these are the things you can change during transcoding. Secondly, the amount of RAM needed for each texture is huge! Super-compressed KTX files Transcoding is the process of taking a video file that’s been encoded, decoding it, making some kind of alternation to it, and then encoding it again. Maybe Unity makes a jobified/threadable version of LoadImage some day, but right now it's a clog. Decoded to ARGB 8, occupying 5.3 MB eachįirst, we can see that all the work is happening on the main thread (done via Texture2D.LoadImage), which freezes the demo for up to a second.Decoded to RGB 8, which occupies 4 MB per imageįor the PNG image with alpha channel it's even worse. ![]() Tests are run on a MacBook Pro (2017) with an Intel(R) Core(TM) i7-7920HQ CPU 3.10GHz ( 4 cores, 8 threads ). It uses the KtxUnity package for loading the KTX files. At first it's loaded from Jpeg/PNG format and then via a BasisU super-compressed KTX 2.0 file (both pre-loaded into memory).įeel free to run the benchmark project yourself. One is color only, one has an alpha channel. Super dense transcoding in a cost-effective 1 RU platform. In these test an 1024 by 1024 pixel images is loaded. A video transcoder is used to convert video from one format to another. ![]() Let me show you some benchmark results of it being integrated into Unity. ![]() Also, because of the default unchangeable port number of plex I can't have both plex's running.Subscribe subscribe Benchmarking Basis Universal Transcoding in Unityīasis Universal super-compressed textures are awesome (read the details). A great tool that simply does what its name indicates, transcodes video super fast. ![]() Supported sampling rates: Narrowband -8kHz Wideband -16 kHz Super Wideband -24 kHz Fullband -48 kHz. Super Transcoder Video transcoding made simple and fast. I know, it's all weird and confusing but my question is if there's another way to get /dev/dri/ to populate without having to run package center plex. Super Transcoder is a simple video transcoding tool that is surprisingly fast. High speed VoIP codec transcoding software. dev/dri/ also magically goes empty after a few days even if there's no power loss.Ĭurrently I have some scheduled scripts that run at 5am that stops docker plex, installs package center plex, stops package center plex, then starts docker plex to ensure hw transcoding will be available at least daily if there's a power loss or something that happens without me being aware of it. RTD Platform4(Transcoding, IP) RTD Platform5(Decoding, 4-channel. Rebooting (manually or from losing power) results in no /dev/dri/ being empty again and I have to stop docker plex and run package center plex then stop it and start docker plex for hw transcoding to start working again in docker. Multichannel HD Video H.264 Encoder Transcoder Decoder Platform. I can get hw transcoding to work for plex in docker but to make it work I have to run plex from package center first or /dev/dri/ is empty.
