Epiphany web-browser -

[cruster]

- prone to randomly crashing back to desktop when playing youtube videos full screen. Operating system is up to date: apt-get update and apt-get upgrade. Pi2 and Pi3 same behaviour. Known issue? Any fixes?

This cannot work, at least not without a workaround, which has never been tried.
While the video is decoded by the GPU, it has to be copied back into the frame buffer in real time to appear inside the window. This does work for medium image sizes, but not for a whole screen.
There are other solutions (but not with epiphany).

Hi, what can't work? Chromium? or playing youtube full screen through Epiphany?

...
Because I am using Chromium on my pi3 w/Rasbian-Jessie, to watch youtube videos full screen.

I tried "sudo apt-get install chromium-browser" but got a message saying the package was missing, has been obsoleted or is only available from another source. Any ideas where I can get it?

So you are saying you cant watch youtube videos on the pi in Chrome (Chromium)? or are you saying something else?

I'm talking about Epiphany. Chromium is not in the repository and I did not want to try install the Ubuntu version.
How large is your screen? I simply don't believe chromium (software decoding only) can display live web video on a full HD screen.

Thanks. I'll give that a try.

Here is chrome (chromium), and it works perfect with the pi3

Thank you!

OK. I gave it a try. Here's the result:
Playing inside the browser window: Video OK, audio out of sync.
Going to full screen (Full HD 1920x1080):
Video lagging and shaky, perhaps 5 - 10 FPS. audio out of sync.
I have no idea why anybody should enjoy watching this.
And I'm running this on a RPi 3!
In the terminal some error messages; obviously trying to access the wrong GPU.

omxplayerGUI called from kweb: plays perfect in any screen size including full screen, audio in sync, uses 720p version from youtube (much sharper image than in chromium). Starts within 2-3 seconds after hitting the "Play" button in the browser.

Overclock pi3 sdram and cpu, and assign more sdram to gpu is my suggestion (that is what I am doing).

Code: Select all

sudo nano /boot/config.txt

Code: Select all

# uncomment to overclock the arm. 1200 MHz is the default.
arm_freq=1350
core_freq=500
over_voltage=4

# uncomment to overclock memory. 400 Mhz is standard.
sdram_freq=560
sdram_schmoo=0x02000020
over_voltage_sdram_p=6
over_voltage_sdram_i=4
over_voltage_sdram_c=4

# Memory allocation of 1024MB for graphics processor ("gpu_mem=" should be very last line in config.txt)
gpu_mem=256

Overclocking the RPi3 is dangerous and useless. Even without overclocking it starts throttling dramatically if all 4 cores are used (down to 900 MHz in my tests). A heat sink might help a bit (if not boxed in).
Enhancing the GPU memory doesn't help chromium because it doesn't use the GPU.

I have maxed out all 4 cores for hours at 1350mhz, without throttling, without heat sinks or fan, using the official pi3 case, and temps never went higher than 65 C

I does throttle by itself. I have run a test with HandBrake which fully uses all four cores, converting a video. I have been watching temperature and frequency from a terminal all the time (almost an hour). After a very short time, temp. reached 80 C and the system starts throttling down. After a few minutes the freq. was aways between 922 and 960 MHz. The Pi3 is not in a box and receives good air flow.

Slap another 15°C on top of that if you plan on overclocking that GPU and spanking it at the same time and you'll nearly be there. Bear in mind that the internal temperature sensor has been reported as under-reading at the hot end on at least some Pi3B. The proof of the pudding will be if you can run Quake 3 Arena at 1920x1080 without throttling back. I'd like to think it could.

I think we should. After you...

Chromium by default does not have hardware acceleration. I saw a chrome extension that would play it in omxplayer using youtube-dl. With the OpenGL driver Chromium is hardware accelerated but I'm not sure how that is for video.

I'm going to see if I can try and integrate youtube-dl into the Chromium source code or at least as an extension.
