Efficient transmitting of decoded frames to the display is just as important as hw accelerated decoding, if not more. Yet, many people only care about the decoding part. On embedded platforms like the imx6, this means that zerocopy must be enforced, that is, ensure that _no_ copies of frames are made with the CPU. If copies are necessary, they must be done by using DMA transfers only. With stock WebKit, you can pretty much forget about that. Look at this source: https://github.com/WebKit/webkit/blob/master/Source/WebCore/platform/graphics/gstreamer/VideoSinkGStreamer.cpp#L138 note how it copies pixels with the CPU. There is apparently a GL-based alternative, but I haven't seen it in action yet. Also, if TEXTURE_MAPPER_GL implies Desktop OpenGL (without being able to choose OpenGL ES instead), it means it will use the wrong API for embedded devices (*never* use the regular OpenGL, since it is made for desktops - use OpenGL ES instead). With OpenGL ES, there is a Vivante GPU specific extension that allows for zerocopy. But this has to be integrated into WebKit, which is probably rather difficult.

Right, I saw that, too. For zero copy, you would need a imx6-specific hack^H^H^H^H modification. So the first question becomes is this. Q. Does Freescale provide any kind of support for hardware accelerated HTML5 video on the imx6? A. No. I already knew this.

Keep in mind what I wrote about the direct textures. If WebKit has a GLES-based rendering backend, these textures could be used for smooth video playback. It'd have to extract the physical address out of the decoded GStreamer frame (possible by using the appsink GStreamer element) and pass it on to the texture, and release the GStreamer frame once that video frame has been shown and the next frame is to be displayed. I also use the direct textures for smooth zerocopy playback in Chromium. One remark: Power consumption wise, using a 3D API (and therefore the GPU's 3D core) for 2D operations isn't so efficient. But, adding a G2D-based backend for example would be much more work. (G2D is a highlevel API for controlling the GPU's 2D core, which uses less power.) ^ permalink raw reply [flat|nested] 31+ messages in thread

It looks to me like this work is from late August. Earlier this year (March?) there was some talk about Chromium, and the FSL Yocto UG (Rev L3.10.31_1.1.0-alpha, 05/2014) also mentions Chromium with HW acceleration (although I couldn't get it working).

Its main target version is 37.0.2062.94, which is also the current stable version of Chromium in meta-browser. These talks were related regarding some ideas for the implementation, but the code itself is completely new. As for WebKit-GTK, I have heard of some efforts for it, but this was told to me offline, and it was months ago. I don't follow its development. ^ permalink raw reply [flat|nested] 31+ messages in thread

Carlos has already made clear it is in the community. It is available in master branches of Community so use those or port them. We have several customers using this already and been working fine. Regarding Qt5, I added the patch for Qt Multimedia to work with acceleration in Daisy and it has been integrated in 5.3 which is in use in master. -- Otavio Salvador O.S.

If you look at the other posts in this thread, you will see that I am not the only one. So please forgive my ignorance and kindly explain what you mean by "master branches of Community". In order to port anything, I need to know 1) the git repositories and 2) the specific commits.

With the kernel in the alpha/beta branch, we need 144 MB for CMA. I am sure this is due to something dumb in the thousands of new FSL kernel patches, but I haven't had the time to track this down. The daisy kernel worked on that board (with full screen video) with a CMA of 64 MB, but unfortunately the newer user space does *not* work with the daisy kernel.

IIRC, galcore is only one of many drivers using the CMA pool. I was using galcore.contiguousSize=4194304. It looks like the other drivers/libs are using way more and larger buffers. Anyhow, the FSL beta kernel is unusable for me, because the serial console is broken. Thanks, Richard ^ permalink raw reply [flat|nested] 31+ messages in thread

Hm, up until now I didn't realize that these are two different things. For daisy, I used fsl-community-bsp-platform, but for the beta, I used fsl-arm-yocto-bsp. So, if I understood correctly, repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git gets me the "offical" FSL project, but repo init -u https://github.com/Freescale/fsl-community-bsp-platform gets me the "community" project.

The FSL one is a code drop which is used by Freescale for providing a point on time with tested code. This is the one they test internally with their QA process and is static so no bugfixes, security updates and so on. Once this is done, the updates are ported to the FSL Community BSP one. This is to provide a reference BSP and platform for people to build products upon it. The goal of both are different.

The 0.10 Freescale plugins for the VPU are known to not work with WebKit. See https://bugzilla.yoctoproject.org/show_bug.cgi?id=4155 and https://bugzilla.yoctoproject.org/show_bug.cgi?id=4156. Check if it was built with its GStreamer 0.10 or 1.0 backend. With 1.0 , you can use gstreamer-imx for decoding.

It was rather strange, though. When the internal WebKit copy of qtwebkit detected GStreamer 1.0 , it switched to 1.0 as the backend. Otherwise, is used 0.10. This is strange because Qt is (or was? I am not up to date) firmly 0.10 based, at least QtMultimedia, and it is generally not possible to use both 0.10 and 1.0 in the same process. I guess it worked because WebKit was built in the multi-process mode. When I get the time, I'll try again, and see if gstreamer-imx is being used for decoding. With any luck, I'll be able to see any frames. You can try this: in Yocto, first build gstreamer 1.0 (and -base/good/bad/ugly) explicitely. Meaning, call "bitbake gstreamer1.0 gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav". *Then*, try to build WebKit. Use bitbake -c configure, so you get the chance to look into the configure log, to see if it is using 0.10 or 1.0. (If you want to be sure it doesn't use 0.10, first remove 0.10 from your Yocto build by running "bitbake -c cleansstate gstreamer gst-plugins-base gst-plugins-good gst-plugins-bad gst-plugins-ugly gst-ffmpeg".) ^ permalink raw reply [flat|nested] 31+ messages in thread
