Needless to say that loading this (a video file directly) with other WebKit based launchers/browsers works fine.
I actually reported https://bugs.webkit.org/show_bug.cgi?id=183259 recently. Probably unrelated, though.

I think its something else maybe? as this works with any other launcher using the very same webkit, but not with cog.
Examples:
-
You can test to build cog with webkitgtk+ support (to test easier on the desktop) with:
cmake -DCOG_USE_WEBKITGTK=ONand then test cog vs webkitgtk+ minibrowser vs epiphany.
Loading the video directly works with epiphany and webkitgtk+ minibrowser, but not with cog. -
And the same if you build for WPE. Loading the video works on dyz, but not on cog.

Interestingly enough, a WebKitGTK+ build of Cog works fine for me, and a WPE build gets me a different warning, notice the Frame load interrupted below:

@clopez: BTW, your log output has Plug-in handled load, which is kind of suspicious. Were you running a Cog WebKitGTK+ build with the Flash plug-in installed? (Or some other plug-in which can play videos.)

This happens also on a board with WPE recently built with meta-webkit. So its not related to NPAPI plugins as:
- WPE doesn't support that (AFAIK)
- I have no installed any NPAPI plugins on the image.

@clopez: True, there is no support for NPAPI plug-ins in WPE, yet.
According to this WebKit bug the Plug-in handled load is returned when loading the resource has been passed to some plugin or media engine. It seems that in this case we still get notified of a load “error”, but we need to ignore it and let WebKit handle that anyway (see this in the Epiphany code).
Conclusion: the load-error handling in Cog needs some extra juice, I'll try to come up with a patch.
(Also, the WebKit API reference documentation could be clearer in this regard, currently I cannot find any notes about which errors can be received in the load-failed signal!)

I have figured out why I was getting Frame load interrupted: the local build of WPE that I have been using for testing this had video support disabled at build time. Let's rebuilt WPE with video support enabled to test this properly before submitting the PR!

I'm actually experiencing what seems like the same issue using cog 0.3.1 and WPE Webkit 2.24.2, compiled with ENABLE_VIDEO=ON. I get this error in console when running COG_PLATFORM_FDO_VIEW_FULLSCREEN=1 cog -P fdo https://people.igalia.com/clopez/wkbug/video/big_buck_bunny.mp4:
(cog:4804): Cog-WARNING **: 02:04:02.763: <https://people.igalia.com/clopez/wkbug/video/big_buck_bunny.mp4> Page load error: Frame load interrupted
The cog window shows the same text.
Any ideas on what could cause this still? 0.3.1 has this fix from what I can tell. These are the enabled features for my WPE build:
-- Enabled features:
-- ENABLE_ACCELERATED_2D_CANVAS ........... OFF
-- ENABLE_ENCRYPTED_MEDIA OFF
-- ENABLE_GTKDOC .......................... OFF
-- ENABLE_MEDIA_SOURCE ON
-- ENABLE_VIDEO ........................... ON
-- ENABLE_WEBDRIVER ON
-- ENABLE_WEB_AUDIO ....................... ON
-- ENABLE_WEB_CRYPTO ON
-- ENABLE_WPE_QT_API ...................... OFF
-- ENABLE_XSLT ON
-- USE_OPENJPEG ........................... ON
-- USE_WOFF2 ON

I can't reproduce with cog+webkitgtk. Didn't tried with cog+wpe as I don't have a build at hand, not sure if some one else can check.
Are you able to reproduce the video with gstreamer? (to discard a decoder problem)
This should play the video
gst-play-1.0 https://people.igalia.com/clopez/wkbug/video/big_buck_bunny.mp4
Otherwise you are missing the h264 decoders on your build or something like that

Thanks, will try with gstreamer and report back.

Reached end of play list.
This seems related to audio? I do have pulseaudio installed and aplay -l lists valid playback devices. Will see if I can play a test audio file.
