shaka-player-embedded is a C++ library typically used in Video, Video Utils applications. shaka-player-embedded has no bugs, it has no vulnerabilities and it has low support. However shaka-player-embedded has a Non-SPDX License. You can download it from GitHub.

Shaka Player Embedded is a framework that runs Shaka Player in native (C++) apps. This gives a cross-platform interface to Shaka Player allowing native apps to use the player. Your native apps can now be built with the same features, behavior, and API as your Shaka-based web apps. In addition to the C++ API, we provide a high-level wrapper for iOS called ShakaPlayer and ShakaPlayerView which can be used from either Objective-C or Swift. Documentation: Tutorials: Releases:

            According to the docs only three options are available (nodownload, nofullscreen, and noremoteplayback) and none seems to do what you want.
            And you can't style the browser's default control set, but you can use the (JavaScript) Media API to build your own control set which of course you can style in any way that you like. See this CodePen.

            The issue is because this in the setTimeout() function handler refers to that function, not to the element reference provided in the invocation of the outer hoverVideo() or hideVideo() functions.

            To fix this issue create a variable in the outer scope to retain the reference to this which you use within the setTimeout():

            Javascript: frame precise video stop
            Asked 2022-Jan-28 at 14:55

            I would like to be able to robustly stop a video when the video arrives on some specified frames in order to do oral presentations based on videos made with Blender, Manim...

            I'm aware of this question, but the problem is that the video does not stops exactly at the good frame. Sometimes it continues forward for one frame and when I force it to come back to the initial frame we see the video going backward, which is weird. Even worse, if the next frame is completely different (different background...) this will be very visible.

            To illustrate my issues, I created a demo project here (just click "next" and see that when the video stops, sometimes it goes backward). The full code is here.

            The important part of the code I'm using is:

            The video has frame rate of 25fps, and not 24fps:

            After putting the correct value it works ok: demo
            The VideoFrame api heavily relies on FPS provided by you. You can find FPS of your videos offline and send as metadata along with stop frames from server.

            The site videoplayer.handmadeproductions.de uses window.requestAnimationFrame() to get the callback.

            There is a new better alternative to requestAnimationFrame. The requestVideoFrameCallback(), allows us to do per-video-frame operations on video.

            1fr

            The first thing you need to know is that 1fr is equivalent to minmax(auto, 1fr), meaning that the container won't be smaller than its content, by default.

            So, start by replacing 1fr with minmax(0, 1fr). That will solve the overflow problem.

            Inconsistent frame number with ffmpeg
            Asked 2022-Jan-16 at 00:46

            I'm having regularly issue with hvc1 videos getting an inconsistent number of frames between ffprobe info and FFmpeg info, and I would like to know what could be the reason for this issue and how if it's possible to solve it without re-encoding the video.

            I wrote the following sample script with a test video I have

            I split the video into 5-sec segments and I get ffprobe giving the expected video length but FFmpeg gave 3 frames less than expected on every segment but the first one.

            The issue is exactly the same if I split by 10 seconds or any split, I always lose 3 frames.

            I noted that the first segment is always 3 frames smaller (on ffprobe) than the other ones and it's the only consistent one.

            Here is an example script I wrote to test this issue :

            ...

            ANSWER

            Answered 2022-Jan-11 at 22:08

            The source of the differences is that FFprobe counts the discarded packets, and FFmpeg doesn't count the discarded packets as frames.

            Your results are consistent with video stream that is created with 3 B-Frames (3 consecutive B-Frames for every P-Frame or I-Frame).

            According to Wikipedia:

            I‑frames are the least compressible but don't require other video frames to decode.
            P‑frames can use data from previous frames to decompress and are more compressible than I‑frames.
            B‑frames can use both previous and forward frames for data reference to get the highest amount of data compression.

            When splitting a video with P-Frame and B-Frame into segments without re-encoding, the dependency chain breaks.

            • There are (almost) always frames that depends upon frames from the previous segment or the next segment.
            • The above frames are kept, but the matching packets are marked as "discarded" (marked with AV_PKT_FLAG_DISCARD flag).

            For the purpose of working on the same dataset, we my build synthetic video (to be used as input).

            Install shaka-player-embedded

            This does not require a C++ compiler as it uses a pre-compiled version of clang downloaded from Google Cloud Storage. However, it does require a C++11 compatible C++ library (installed with most compilers, e.g. gcc). We use git submodules to manage third-party dependencies. You can run git submodule update (or pass --recurse-submodules to git clone) to download all the submodules; or you can wait and have the configure script download only those you need. You need to run configure to setup configuration settings. You can pass --help to see some of the options you can use. We don't support in-tree builds; you need to run configure in another directory. Once configure is done, you can build using build.py. There is a Makefile that will run the script for you if you prefer. Once it is built, you can use the resulting shared library. On iOS, there will be a ShakaPlayerEmbedded.framework folder that you use; there is also a ShakaPlayerEmbedded.FFmpeg.framework bundle that you need to include in your app, but you shouldn't use it directly since we don't maintain ABI for it. On other platforms, there is a libshaka-player-embedded.dylib or a libshaka-player-embedded.so file you can use. Like iOS, there is a libshaka-player-embedded.ffmpeg.* file you need to include too. If you are using a custom --eme-impl, you need to copy the respective shared libraries too, if needed.
            The source is managed by Git at https://www.github.com/google/shaka-player-embedded. You will need these tools available on your development system:
            Git v1.7.5+
            Python v2.7 Requires installing package enum34
            autoconf 2.57+ m4 automake 1.7+ perl
            Install Chromium depot tools, which contains ninja and other required tools. See https://www.chromium.org/developers/how-tos/install-depot-tools for details.
            Get the source
            Configure and Build
            Copy the shared library

            Support

            We only support iOS at this time, but other platforms could be added. Because many on our team use Linux, there is a Linux port included to make it easier to work on non-iOS-specific features. Linux is not, however, a first-class target platform at this time.
