Download intell quicksync1/31/2024 Version 5 (Skylake) The Skylake microarchitecture adds a full fixed-function H.265/HEVC main/8-bit encoding and decoding acceleration, hybrid and partial HEVC main10/10-bit decoding acceleration, JPEG encoding acceleration for resolutions up to 16,000×16,000 pixels, and partial VP9 encoding and decoding acceleration. Also, it has two independent bit stream decoder (BSD) rings to process video commands on GT3 GPUs this allows one BSD ring to process decoding and the other BSD ring to process encoding at the same time. Version 4 (Broadwell) The Broadwell microarchitecture adds VP8 hardware decoding support. This generation of Quick Sync supports the H.264/MPEG-4 AVC, VC-1 and H.262/MPEG-2 Part 2 video standards. The highest-quality TU1 setting is intended to be higher quality than Ivy Bridge's version, and the highest speed TU7 setting should be faster, higher-quality, and more battery-friendly for mobile devices. It has seven hard-coded quality/performance levels (called "target usages"), compared to the three in previous generations. Version 3 (Haswell) The Haswell microarchitecture implementation is focused on quality, with speed about the same as before (for any given clip length vs. Version 2 (Ivy Bridge) The Ivy Bridge microarchitecture included a "next-generation" implementation of Quick Sync. " Version 1 (Sandy Bridge) Quick Sync was initially built into some Sandy Bridge CPUs, but not into Sandy Bridge Pentiums or Celerons. Troubleshooting ¶Ī good way to troubleshoot transcoding issues is to increase the log level and examine the entire FFmpeg command and its output.There are different versions of Intel Quick Sync, and each version offers different features, so some things will depend on which Intel processor your computer uses. For more information, see the FFmpeg documentation. Which devices need to be shared and whether additional drivers are required depends on your specific hardware. Then restart the services for the changes to take effect. If you want to use other hardware for transcoding, choose the appropriate AVC encoder and share the required devices with the photoprism service, as shown in the examples above. Note that the Raspberry Pi hardware currently only supports video resolutions up to 2160p. Carefully monitor your server's logs and increase the available GPU and/or CMA memory allocations if necessary. Some server configurations, especially Raspberry Pi's, may experience memory allocation issues when using hardware acceleration. To reduce the size of AVC videos, you can manually replace the original files with a smaller version or wait for a future release that offers this functionality. Note that MPEG-4 AVC videos are not re-encoded if they exceed the configured bitrate limit. If the bitrate is significantly exceeded in your environment and you want improvements to be implemented, we recommend that you take a look at the FFmpeg documentation and the parameters in our source code so you can tell us which parameters should be changed to make it work for you. It may also depend on the operating system and the GPU drivers. Keep in mind that this is a "soft limit", so the actual bitrate varies and depends on the encoder used as well as the specific FFmpeg parameters, which in turn depend on the encoder. You can limit the bitrate of the AVC encoder with the config option PHOTOPRISM_FFMPEG_BITRATE. ![]() This depends on your hardware and operating system, so we can only give you examples that may need to be changed to work for you. In addition, the service must have permission to use the related video devices. When using our Docker images, it is already pre-installed. ![]() For transcoding to work, FFmpeg must be enabled and installed.
