Improving video playback

[Sharkfin]

I'm using a 3.5" lcd touchscreen that is connected to my RPi 2 Model B through an SPI interface.

I'm currently using notro's fbtft drivers to drive the screen and it works fine.

However, I need it to be able to play videos smoothly but it keeps turning out choppy. For example, I tested it with a short video of a seaside with waves crashing but the waves look like they're afraid of the sand with the way they're inching closer second by second .___.

I've tried mplayer (-vo fbdev2:/dev/fb1) and omxplayer with fbcp. I've also tried increasing the speed and fps of the screen itself by editing the dtoverlay in /boot/config.txt. Are there any other ways to improve video playback that I can try?

Hmmm. Omxplayer works fine for me (Raspberry Pi B+), but I have a normal computer monitor (1024x768 I think). Are you trying to play HD video? I'm not sure, but I don't think RPi B handles HD very well...

All versions of the Pi handle HD video extremely well. It's one of the things the GPU was designed for.

However, the GPU was not designed to drive a screen via the SPI interface, so a lot of the work is going to have to be done using the ARM CPUs. That might be the problem. I haven't got one of those screens, so I can't check.

The Pi can easily play back 1080p30 to the HDMI port. In this case, the video needs to be copied from to the Linux FB, and I suspect copied again to the TFT. That is going to be a huge CPU hog, probably more than it can handle at higher resolutions. You might even exceed memory bandwidth, when added to all the other memory accesses going on.

Try lower and lower resolutions until it works.

I've not found any evidence of success running North American on air full hd off a hdhomerun on any pi. That would be the right test case, I think.

I don't know what may be special about your "North American on air full hd", but my RPi2 replaces a hdomerun completely (with an USB Sat-Receiver) and can play any kind of SD and HD streams at the same time (in addition to serving them on the network). It can also transcode all TV streams in real time to low bitrate streams that can be sent across internet connections.
