![]() There are some platform differences for playback-rate behaviour:īy default playback rates higher than 2.0 causes the player to only show key-frames. Scripting playback rate: // After the video is loaded and metadata event fires you can use these: Alternatively a fast key-frame-only codec could be used, such as Hap. Videos with more key-frames (or ideally all key-frames) and with less complex encoding (eg no B frames, CABAC disabled etc) will work better. ![]() ![]() Video encoding can also help the performance of a change in playback rate. This approach would work on all platforms. One safe alternative to adjusting rate is to pause the video and fast seek to simulate a change in playback rate. Using negative values isn’t generally recommended as it isn’t as well supported, but if you do have to use a negative rate then also try keeping the numbers small such as: -0.25, -0.5, -1.0Īudio also may or may not play when changing the playback rate - this depends on the platform (see table below). Increasing playback rate usually places more demand on the video decoder and also on the disk/network source, so these limit how high you can set the playback rate. Going up to 4.0 might be possible depending on your platform, machine specs and the codec used. There are some platform differences for seeking behaviour: If the frame rate can not be determined (eg in some HLS media the frame rate returns zero) then you can still use the frame-based time methods by manually supplying the frame rate as an optional final parameter to the above methods: // After the video is loaded and metadata event fires you can use these: Get the highest frame number you can seek to (the same as durationFrames-1) Media that has a known constant frame rate can be seeked using frames: // After the video is loaded and metadata event fires you can use these: TimeRange seekableRange = Helper.GetTimelineRange((), ()) Seek to the current 'live' time for a live stream This is only currently available on macOS, iOS, iPadOS and tvOS Seek to closest keyframe allowing keyframe to be either ahead, behind or on both sides of the desired time Seek to nearest keyframe at 24 seconds Get the ranges of time that can be seeked between ![]() The only difference between them is the number of files you can search at once - in the free version you can search up to 50 files, while in the paid version - up to 20,000 files.All time operations are done in seconds using doubles: // After the video is loaded and metadata event fires you can use these:ĭouble duration = () ĭouble time = () SeekFast is available in two versions - Free and Full version. SeekFast supports searching files of nearly all popular programming languages: PHP (php), C and C + + (c, cpp, h), Java (java, jsp), Perl (pl, plx), HTML (html, htm), XML (xml), properties, log files. With SeekFast this happens in a second, which can save you many hours of digging and searching in the code. When thousands of files are available, it is extremely difficult to find a function, variable or text throughout them. SeekFast is extremely useful for searching in large software projects. If you want to view only the text, you can click on the phrase and see the text surrounding it. You can open the corresponding file with one click. ![]() For greater convenience, search terms are highlighted in red. You get the file names and sentences containing your search words immediately. The SeekFast technology is unique and has no analogue in the world. SeekFast uses powerful technology for sorting, that produces results similar to what you would get from Google on the net. Like Google, SeekFast shows you the most relevant results on the top. SeekFast is compatible with all modern versions of Windows - (Windows 7, Windows 8, Windows 10), and with all commonly used macOS versions. Select a folder, enter search words and get search results in a second. With SeekFast the search is easy, fast and convenient. SeekFast can search in all Microsoft Word documents, PDF, Excel, PowerPoint, OpenOffice, LibreOffice, LaTeX, RTF and text files in a folder and its subfolders on your computer. SeekFast is a software tool for quick and easy text search on your computer. ![]()
