The linked url plays for a few seconds then a seek to 0 at rate=0 is attempted, this is not working. I use gst git master though, someone needs to check with 1.0.x and 1.2.x.
The same happens to me. The WebProcess actually crashes. I'm using debian's gst packages version 1.2.1
I am not getting a crash, but MiniBrowser just hangs. GStreamer 1.2.1 from WebKitGTK+ dependencies.
(In reply to comment #2) > I am not getting a crash, Not here, like I say in comment 0 it plays a bit and crashes. > but MiniBrowser just hangs. > GStreamer 1.2.1 from WebKitGTK+ dependencies. Here too.
(In reply to comment #3) > Not here, like I say in comment 0 it plays a bit and crashes. After playing a bit with it, it plays a bit and then crashes with debug and with release sometimes it hangs and sometimes it crashes.

On a hunch, I turned off adaptive bitrate (the ABR switch on that page) and the crash went away. I think this may be related to a bug a saw a long time ago where switching video tracks with different output sizes caused a crash (I should have created a bug report for that a while ago but forgot until now).
This seems like a relevant piece of the backtrace: #17 0x00007ffff3815e66 in WebCore::BitmapImage::draw (this=0x1270850, context=0x7fffffffb8e0, dst=..., src=..., styleColorSpace=WebCore::ColorSpaceSRGB, op=WebCore::CompositeCopy, blendMode=WebCore::BlendModeNormal, description=...) at ../../Source/WebCore/platform/graphics/cairo/BitmapImageCairo.cpp:114 114 context->platformContext()->drawSurfaceToContext(surface.get(), dstRect, adjustedSrcRect, context); (gdb) print adjustedSrcRect $5 = {m_location = {m_x = 0, m_y = 0}, m_size = {m_width = 1280, m_height = 720}} (gdb) print dstRect $6 = {m_location = {m_x = 364, m_y = 160}, m_size = {m_width = 700, m_height = 394}}
Also this: #20 0x00007ffff4c5f975 in WebCore::MediaPlayerPrivateGStreamerBase::paint ( this=0x13691c0, context=0x7fffffffb8e0, rect=...) at ../../Source/WebCore/platform/graphics/gstreamer/MediaPlayerPrivateGStreamerBase.cpp:415 415 rect, gstImage->rect(), CompositeCopy, ImageOrientationDescription(), false); (gdb) print gst_caps_to_string(*caps.m_ptr) $13 = (gchar *) 0x1e65b50 "EMPTY"
When video caps change, we follow this process: MediaPlayerPrivateGStreamer::videoCapsChanged() (async) MediaPlayerPrivateGStreamer::notifyPlayerOfVideoCapsChanged() HTMLMediaElement::mediaPlayerEngineUpdated() RenderVideo::updateFromElement() RenderVideo::updatePlayer() RenderVideo::updateIntrinsicSize() I think the problem is that (async) step, which allows rendering to continue before we update the intrinsic size, which leads to trying to write a 1280x720 image into a 700x394 buffer. It would be nice if we could call mediaPlayerEngineUpdated() at the moment the caps change, but I don't think it would safe, since that's supposed to be called on a different thread. Another option is blocking rendering until the intrinsic size is updated, but that seems dangerous (and probably slow). I'm trying to figure out how to get one of these options working: * Resize the image if it doesn't fit in the provided destination buffer. * Skip rendering until the destination buffer is the size we expect.
Here's something interesting. I was curious about how none of the fixes I tried seemed to help, so I tried commenting this out to see if it would cause a crash: static void mediaPlayerPrivateVideoSinkCapsChangedCallback(GObject*, GParamSpec*, MediaPlayerPrivateGStreamer* player) { // player->videoCapsChanged(); } And with that change, it usually doesn't crash, but the video acts weird for a couple seconds at the point where the bitrate changes. Since it still crashes occasionally, I'm guessing this is some sort of timing issue.
I wanted to take a look at this again, but MediaSource doesn't seem to be working at all for me now. It looks like it's runtime disabled by default, but if you run with: Tools/Scripts/run-launcher --gtk --enable-mediasource=true http:/ashif.org/reference/players/javascript/0.2.5/index.html It seems to work, but the video stays grayed out.
I can't get the video to play at all. Neither with git master GStreamer or stable release. Anyone else can?

Same behavior here. From the logs the pipeline gets stuck while going to PAUSED in async and then playbackPosition is invoked in a infinite loop, returning 99:99:99.999999999. The MediaSource src element clearly needs work. :(

Philippe proposed I comment out the registration of http src element [1] to make it fallback to souphttpsrc and see if the problem is in that code. I did this but the video still doesn't work. Will continue investigating. [1] MediaPlayerPrivateGStreamer.cpp: initializeGStreamerAndRegisterWebKitElements()
I suggested that for the Vimeo bug :) The httpsrc element is not used for MSE playback :)
Tried it with that one as well. Sorry for the confusion :) Will investigate that one further tomorrow and once resolved I will get on with this one. Thanks for the help.
Any news about this bug Luis?
Have been very busy with two conferences, trainings, new job and moving to a new city. Bumping it up in my ToDo list. Will keep you updated :)
Assigning this back to nobody since I don't have time to work on it right now.
Works for me with my changes in bug #139441
Let's assume this is fixed then? The linked URL is gone anyway.
