Choppy Video

[jacobgraf]

We are looking to use this for digital signage and occasionally we will have a short promo video play. We are using this as a test video (https://graftechnology.com/video/) but the video is really choppy. I set the GPU_MEM to 448 since that's the max for a 1GB Raspberry Pi 3 but it's still choppy. Any ideas how to get things running smoother? Thanks!

Currently chromium is not utilizing the GPU. To date I have not be able to find how to enable it. Talks are at #22 . Solutions are welcome.

@jacobgraf could you please try this out and tell us if it solves the problem for you?

[guysoft]

I am not sure that would solve it alone.

I was able to get hardware decoding working from Chromium by enabling the experimental gl graphics driver in raspi-config and enabling the --ignore-gpu-blacklist chrome flag, but elements of videos still played choppy.

I tried another Raspberry Pi distribution (OpenElec / XBMC) that runs videos in a dedicated media player. The same MP4 videos played smoothly in the media player app.

Maybe we are trying to squeeze too much out of a web browser. Did you try smaller resolutions?

[tcaddy]

@tailorvj smaller resolutions played smoother, but don't look that great. In the end, I used a more powerful device for the video playback use case.

@jacobgraf Not in browser, but I'm having success using omxplayer. It goes fullscreen over the browser, and when the video is done, it closes and returns to the browser.

Hey, try RC1, it seems to be able to run fast, but it crashes, not sure why.

@jacobgraf Hey, if still relevant, it seems like webm does work on full screen at the moment, its mp4 container that seems to have a bug now. it means that if you convert your video to webm it should work with the new 0.7.0 RC1. Here is a webm video for reference:

This dude managed to get hardware decoding in Chromium:

It would be interesting if you take a look at it. Would be really useful to have a merge of these two projects.
