Video Codec For Mac


Contrary to previous information about 3rd party video codec support changing with the release of macOS Catalina, and the end of 3rd party codec support natively in the macOS, according to an Avid Press Release announced at IBC 2019 last weekend, Avid appear to be suggesting that there will be macOS support for Avid DNxHR and DNxHD codecs. As part of their IBC 2019 coverage Avid. Perian is one stop codec resource on Mac similar to K-Lite Codec Pack on Windows. Perian is a free, open source, QuickTime component that extends QuickTime support for many popular types of media, including MKV, FLV, WMV, AVI, DivX, and XviD. How to download and install K-Lite Codec for Mac – Perian? Perian is just 3 MB in size.

Video Codec For Mac

But, typically when any user tries to play external (received) video clips on their computer, they may face one or the other playback issues. Sometimes, these video files fail to play properly, at other times they never play at all.

And, at this minute definitely, you will try to get another copy of the unplayable video, if possible (if it is downloaded from the internet or a friend sent you that video). If you cannot obtain the photocopy of the file, then you will try to repair the video file. But, it is not always the corruption, which makes your video file unplayable or results in playback issues. Even codec problem can cause general issues in playing your videos. and, for fixing videos tools you choose must be compatible with codec of the video. For fixing MPEG4 video files you need tool that supports this codec. Likewise, for other codecs too. Hence, it is important to know the codec of video file.

What is Codec?

A codec is a computer software, which encodes and decodes a video or audio file. Every single audio, as well as a video file, is made up of a codec since it keeps your video/audio file tiny and makes playback easy. And, codec usually functions with your system media player as a part of it.

Codec installed on your system decodes your videos, music files, which are encoded with a specific codec and allows the media player to play them. If you are experiencing any issue while playing your videos, then you can have a guess that one of your codecs used to play the video might have got corrupted. If not, it might be that you don’t have the right codec on your computer to play the video appropriately.

Many media player including VLC has their own set of built-in codecs. But, if you are employing any other player then how to find the codec of a video that you are playing? Well, here is the way to do it.

How to find the codec of a video file using the manual method?

You can easily get video codec information on your Windows and Mac computers using your own operating system functionalities. Just follow these step by step guidance to do so.

On Windows:

Go to the location where the video file is stored

  • Select the video, whose codec info you want to know
  • Right click on the file
  • Select Properties
  • Switch to Summary tab
  • Check description
  • You will see audio format and the video compression
  • These are the used codecs for your video clip

On Mac:

Navigate the folder that holds your video clip

  • Pick the video to get its codec info
  • Right-click on the selected file
  • Click on Get Info option
  • Jump to Summary
  • Go through the information
  • You can see codecs of both audio and video format

Via VLC:

Open the video in VLC, to know its codec

  • Go to the playlist and right click on it
  • Choose Tools
  • Select MediaInformation
  • Don’t forget to mark the checkbox Codec Details

Note down the codecs that are used to create the video file. Now, you can download the required (noted) codecs from their official websites. Once you completed the download process, install them and open the video file using your regular media player.

If you cannot find out the codec information of your video file or if you feel difficulty in checking it manually or the video clip is still not playing even after you have installed the codec, then you can make use of various available tools like MediaInfo, VideoInspector, Codec Installer, GSpot, AVIcodec etc. to get adequate codec and play your video.

If you are looking to make use of the dedicated decoding/encoding hardware on your GPU in an existing application you can leverage the integration already available in FFmpeg. FFmpeg should be used for evaluation or quick integration, but it may not provide control over every encoder parameter. NVDECODE and NVENCODE APIs should be used for low-level granular control over various encode/decode parameters and if you want to directly tap into the hardware decoder/encoder. This access is available through the Video Codec SDK.

A: The support matrix is listed The client application should also query the capabilities using the respective capability APIs before enabling any feature.

A: We strongly recommend all application developers to go through the programming guides in detail before writing any application. In particular, for some hints on this question, please go through the following sections in the documentation. These sections provide valuable tips for optimizing latency/memory utilization and choosing the right settings for different use-cases.

  1. 'Recommended NVENC Settings' in NVECODE API Programming Guide, included in the Video Codec SDK
  2. 'Writing an Efficient Decode Application' in NVDECODE API Programming Guide, included in the Video Codec SDK

A: Video encoding latency consists of two components: (a) Latency due to encoding algorithm (e.g. B-frames, look-ahead, VBV buffering), and (b) Latency due to the processing required to encode the bits using hardware or software. For a typical end-to-end streaming scenario to incur low latency, it is important to lower both components as much as possible. Typically, latency in (a) can be minimized by choosing infinite GOP with IPPPP... structure, no look-ahead and lowest possible VBV buffer for the given bitrate and available channel bandwidth, without giving away too much of encoding quality. Each of these can all be set via NVENCODE API. In Video SDK 10.0 and above, setting the tuning info to low-latency or ultra-low-latency will set most of these parameters automatically. Latency contributed by (b) can be minimized by choosing the correct preset, and rate control mode with correct number of rate control passes. Naturally, 2-pass requires more time to encode than 1-pass rate control mode. Running quarter-resolution first pass requires less time than running both passes at full resolution.

In addition to the above, the overall encoding latency is also affected by efficient application design (or lack thereof). Since NVENC can run in parallel to CUDA and graphics workload, it is important to ensure that the NVENC pipeline is kept fed with data and the context switches between NVENC pre-processing (which uses small amount of CUDA bandwidth) and other graphics/CUDA workload are minimized. The specifics of this depend on the workload, but should be analyzed using a tool such as GPUView (available as a part of Windows Performance Toolkit).

A: The Video Codec SDK provides samples specifically designed to give optimal performance. Please refer to applications with suffix '…perf' inside the Video Codec SDK. User can run these applications for measuring maximum throughput. The samples in the Optical Flow SDK are optimized for performance.

A: First of all, it is important to note that the aggregate video encoding performance of GPUs is not solely defined by the raw number of NVENCs on the GPU silicon. As anyone familiar with video encoding will know, talking about video encoding performance without any reference to encoding quality is meaningless. For example, one can encode a video at blazing fast speed, without any regard to quality and claim extremely high performance, doubling the performance on GPUs with multiple NVENC engines. But such usage may not be of much use in practical situations. Therefore, it is important to think of encoding performance at a specific quality. NVIDIA encoding benchmarks use the bitrate savings compared with open source encoders x264 and x265's medium preset output, as a measure of the encoding quality. The performance vs. quality spectrum thus obtained is published for various generations of GPUs on Video Codec SDK web site. Most of the commonly used presets on Pascal have an equivalent preset in Turing with similar quality and 2x performance, thereby making it possible to get the same performance from both GPU generations, despite Turing GPUs having only 1 NVENC engine. This requires the application to choose appropriate encoding settings, depending upon the GPU in use. For low-latency presets and tuning, Turing NVENC provides equivalent settings to achieve higher performance per NVENC than Pascal NVENC for latency tolerant encoding. For latency-sensitive (low-latency) encoding, Turing NVENC does not provide 2x performance, but that's not needed because most of the low-latency scenarios are bottlenecked by the graphics/CUDA utilization and not NVENC utilization.

In short, despite the reduction of number of NVENCs from Pascal to Turing, one should be able to achieve equivalent encoding performance per GPU, in most practical use cases by adjusting the encoding settings to normalize the encoding quality.

A: NVENCODE API expose APIs which allow users to query the maximum API versions supported by the underlying driver. Depending on the maximum API version supported by driver, the application can launch code at runtime compiled with the appropriate API.

A: For decoder, please refer to the NVDEC application note included in the SDK documentation to get an idea about performance. For encoder, the answer depends on many factors, some of which include: GPU in use and its clock speed, settings used for encoding (i.e. encode quality), memory bandwidth available, application design. It is especially important to note that GPU encoding performance is always tied to the encoding quality, and the performance can vary greatly depending upon the chosen settings. For example, B-frames, 2-pass rate control mode, or look-ahead will improve the encoding quality at the cost of performance. Encoding presets also influence quality vs performance trade-off significantly. Please refer to the table containing indicative performance figures for the video encoder in NVENC application note included in the SDK package.

A: Create separate Cuda streams for encode and decode. For NVDECODEAPI and NVENCODEAPI you can specify the stream where you want to Cuda kernels using CUVIDPROCPARAMS::output_stream and NvEncSetIOCudaStreams(..) respectively.
