Looking for testers for ES Video Preview on Raspberry Pi

pjft

Hi all, and apologies for the delay.

Thanks for all the replies, and for all the tips. Thanks @Rion for the Emumovies reference. I had seen others mentioning it in the past, may use them for the 320x240 videos, or end up paying for a sub though the 640x480 videos will just not be good for the RPi as I find that most resolutions above 480x360 end up causing the RPi to slowly, but surely, get hotter until it overheats, whereas this one can still plateau at around 77C-78C. Too close for comfort, but still good.

A question: do they have videos at native resolution - or, alternatively, is there a place with native resolution videos?

EDIT: @Rion - can a premium member download High Quality videos from EmuMovies at 320x240? Or are their HQ ones only at 640x480? Most of the arcade games and console games on these old systems ran at resolutions lower than 320x240, so I fail to see why there wouldn't be 320x240 videos with much crisper definition, like the ones at http://www.progettosnaps.net/videosnaps/ for MAME (great site).

@MWGemini for videos, it's not fully scientific, as the temperature will slowly grow until it plateaus (or crosses) the threshold. You may try this video:

http://www.progettosnaps.net/videosnaps/mp4/astdelux.mp4

Which is 640x480. It should slowly increase temperature until it hits the 80C threshold (or, depending on your air flow, maybe close enough to that).

http://www.progettosnaps.net/videosnaps/mp4/aburner.mp4

is 320x224 I believe, and it'll plateau at lower temperatures, about 73C-74C if I recall correctly.

My case is the official RPi case,

https://www.raspberrypi.org/blog/raspberry-pi-official-case/

Which is close to a full on plastic enclosure of the Pi (which will cause a difference in cooling - or heat release - to @fieldofcows ' experiment, as it was with the RPi out in the open, if I understood correctly).

I have removed two of the the side snap-on parts of the case (the ones where I plug the HDMI cable, and the one next to the GPIO pins) to increase the air flow a little bit around it (see image at https://www.raspberrypi.org/wp-content/uploads/2015/06/construct-500x270.jpg).

Last, I'm running the Carbon theme, with jrassa's pull request to incorporate video in it (https://github.com/RetroPie/es-theme-carbon/pull/20). Which means I downloaded the theme at his GitHub repository: https://github.com/jrassa/es-theme-carbon/tree/video-view

The only change I did was to set

to

like in the OldRoom theme, in the main carbon.xml file, line 103:

https://github.com/jrassa/es-theme-carbon/blob/video-view/carbon.xml

I believe that's the most I can state to help replicate my setup. Truth be told, the first video the problems showed up at were some 60fps, 640x480 video I got from a HyperSpin collection somewhere. You'll likely see the video fail to render properly quite easily.

While I can't remember the exact link for it, from the specifications I suspect you may be well able to replicate it using this video:

https://emumovies.com/files/file/1713-taito-classics-system-intros-hq-480p/

as it states there's one of them at 640x480, 60fps - which I hope free members can download. I'm not at my laptop - traveling for work this week - so I can't test it myself.

My experience (and I suppose expectation for those willing to test it out) is that:

640x480 at 60fps (the first video in the Emumovies download link): rendering problems, which was my first comment that led to @BuZz 's comment on hardware acceleration. @fieldofcows I suppose this one, if you all can indeed replicate the rendering problems with it, will be a good one to test hardware acceleration on. I could test it out on Kodi, actually, and see if it renders well.
640x480 at 30fps (the second video in the Emumovies download link): should render well, but eventually temperature will go past the threshold. 10 mins perhaps. Hopefully the other video I linked from Asteroids Deluxe would also do the trick - it was the first I found that I had a link for.

I was running

watch n 1 get_temp.sh

where get_temp.sh had the script I pasted earlier to show CPU and GPU temperature.

#!/bin/bash
cpuSpeed0=$(cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq)
cpuSpeed1=$(($cpuSpeed0/1000))

cpuTemp0=$(cat /sys/class/thermal/thermal_zone0/temp)
cpuTemp1=$(($cpuTemp0/1000))
cpuTemp2=$(($cpuTemp0/100))
cpuTempM=$(($cpuTemp2 % $cpuTemp1))

gpuTemp0=$(/opt/vc/bin/vcgencmd measure_temp)
gpuTemp0=${gpuTemp0//'/°}
gpuTemp0=${gpuTemp0//temp=/}

echo
echo CPU Speed: $cpuSpeed1" MHz" - CPU Temp: $cpuTemp1"."$cpuTempM"°C" - GPU Temp: $gpuTemp0

Still, I hope this helps - even though there'll be different things for all the scenarios.

Thank you all, tremendously, and have a great week!

@pjft I'm uploading a pack of videos for megadrive-genesis for your testing.

The videos are at 640x480 30fps but re-encoded by me. The videos aren't in the best quality but I think it's good enough for a little preview with good balance between filesize and quality.

Please can you do some test on the Rpi with my videos? because I don't have Rpi and I need to test if they work well or if I need to downscale the resolution.

I'm planning to upload pack with videos, images, and marquees (wheels) but I need to be sure than the videos will work well on rpi and don't waste time re-encoding if the videos need to be downscaled.

I'll post the download link here in about 1 hour.

Thanks in advance.

@Nismo Hi Nismo,

Thank you for the reply. I'll do my best - I'm traveling tomorrow, but today I may be able to squeeze a bit of time to test these out today. In fact, if you can just share one video, I'll just download that one and check it - I won't be able to test out all the videos, but assuming they're all the same, the result would be equivalent.

For the rest of the thread:

I'll try to make a log/report of the temperature using ES and Kodi for the same videos, if they fail. It'd be an interesting comparison, at least for me.

Thanks.

Nismo

@pjft Here you have: https://mega.nz/#!h9lEERaY!Kk6AdgQXSp2FKXJDBbujHGPFNRPtYnaZuir8HznWCrw

Please try with a few of them, because not all videos have the same duration and in consecuence, filesize.
Thanks for testing.

Sure you can. Just point EmuMovies Sync to your rom/roms folder and select the desired quality of the videos you want. It then scans the folder/folders and download the appropriate video snap for that roms with the same name.

watch n 1 get_temp.sh

Thanks for the detailed post! I will try to pull those videos down and modify my gamelists to show them. It might not be today, since I've also got to deal with work stuff... Sometime in the next 48-72 hours or so, probably.

One last question- the command you are running to monitor temperature, you are logging into the Pi via SSH and running that script, correct? Or is that something you have modified EmulationStation to display?

pjft

@MWGemini Not at all, thank you for your time. You - and everyone else here - are literally doing it out of generosity, so I appreciate it very much (as well as I totally understand if it doesn't get looked into).

As for your question, that is correct: I log into my RPi via SSH and just run that script. I do create it beforehand as a file there, and give it permission rights.

Login to Pi via SSH
sudo nano get_temp.sh
Paste the content of the script
Ctrl+X
Y
chmod +x get_temp.sh
watch n 1 get_temp.sh

(you can actually do "n 5" or something else - I believe the number is the number of seconds between calling the script).

Thank you!

MWGemini

@pjft Yep, just wanted to confirm your setup. One side note- 1s polling might be helping to max out the CPU and cause the problem, but even if that's the case, we shouldn't be baking the CPU and board under normal use conditions.

Also, I did just find this thread: https://retropie.org.uk/forum/topic/2218/raspberry-pi-3-idle-load-temperatures-while-running-retropie which has some good temperature related info.

pjft

Thanks. Yeah, I'd poll it after 5 or 10 seconds normally - it was just a sample command.

Here's my log @Nismo @fieldofcows @MWGemini from the EmuMovies linked earlier and a Nismo video. Didn't have the chance to load them on Kodi, but don't expect it to reach the same temperatures.

Using emumovies files directly caused my pi3 to give me temperature warnings when I would preview the files with the latest build of emulationstation. I ended up converting my videos from 640x480 to 320X240. That seemed to help the temperature issue for me.

@HurricaneFan Please can you try the megadrive-genesis video pack i uploaded a few post ago?

So, my last inputs on this whole research for the week. Won't have access to my RPi for a few days as I'm out for work. @fieldofcows @MWGemini

Kodi performs fantastically better at rendering the 640x480@60fps video (the one that ES couldn't as it rendered artifacts, and stuttered). Not only that, it does that at a temperature that's lower and needs lower CPU speed than EmulationStation idle. Likely because it's doing most of the work on the GPU, though I'm not an expert here. The only thing I think I read about in the past was that the reported speed was the rolling CPU clock speed average from the most recent (something) period. So that's interesting that in Kodi it's sometimes reported as 600Mhz when rendering the video.
EmulationStation in idle state still heats the CPU more than Kodi in idle, or rendering the videos. I didn't leave it until it plateaued, but Kodi was in the 45C range rendering the video, whereas EmulationStation idle was climbing slowly towards 55C. I then ended up turning the RPi off as I have to do other things tonight still.

Here's the log, hope it helps:

@Nismo: maybe you missed it, but I tested one of your videos earlier and it did, indeed, show the same behavior as the other 640x480@30 videos, and led to overheating.

Have a great week!

HurricaneFan

@Nismo Downloading now. I'll try to get this tested tonight on my pi3.

HurricaneFan

@Nismo I've downloaded your videos, but I have to update my gamelist.xml. I haven't converted my genesis collection to use your new theme yet. So far I've tested NES and SNES videos so far.

Nismo

@pjft Thank you very much for your testing, i hope you enjoy your travelling and not tooo much work.

@HurricaneFan Same for you, thanks for testing, you don't need to use my theme, you only need to use the videos with any theme with video support. Thanks again.

My interest it's on the videos not in the theme, because i did a lot of re-encoding and i'm affraid all that time re-enconding, it's time lost if i need to dowscale all the videos.

I was just about to open the thread for my theme, and if a need to dowscale all the videos again.... it will take to me almost one month to re-encode again.

My first idea was not to much filesize videos with good quality for previews for use with a little SD card, but now i'm thinking that downscale it's better for performance...

And I have to say, that i do that re-encoding process for all people helping this project, because i use full quality videos under windows, and I want to contribute this project as best i can, so that re-encoded videos are for the forum, not for me, that's because I need to know what's the best for rpi, because I don't have one.

I will upload more art, stay tuned.

Regards to both.

@Nismo Thank you for all that you have done so far. I use the application Handbrake to queue up all my videos to re-encode. It takes a while for the number of videos I have but its super nice just setting it up and letting it do all the work without me needing to do anything.

@HurricaneFan I know what is handbrake, and it's very limited, I know how to re-encode videos and how to batch re-encode, but I need to have all the advanced options available and handbrake it's a very limited program, I don't need programs for batch encoding, I only need people who can test videos, and find the best parameters for a rpi, because i don't have one, I know how to encode and batch encode videos and resize, apply effects, etc, etc.

Only need people who can test my videos because I use windows and i don't want to loose my time if I need to reencode all my videos for downscale.

I don't need optimized videos for me, but i'll try to do it for people with rpi, optimizing filesize, and no temps problems, because I'm trying to do my best for this great forum.

@Nismo Thanks Nismo. As I stated, in its current incarnation it's not ideal, but I have hopes that maybe the EmulationStation video performance can be adjusted, so I'd hold off on re-encoding everything as maybe things will improve.

Thank you for all the hard work!

Funny you should say that. I had play with this last night trying to work out where the high CPU usage stems from. I disabled all rendering code and just left the VLC library rendering into a buffer and the CPU usage (measured through the temperature gain) was the same.

At the moment, VLC is configured to reformat the video pixels to RGBA8888 so I tried some different encoding formats. The native format for my videos takes a bit more work so I just tried some others such as RV16 and RV32. This seemed to make quite a significant difference to the temperature of the pi and is a fairly quick fix to try. I'll put a build together, hopefully tonight for some people to try out to see if it makes a difference.

I don't know much about video formats but is there a prevailing format that is used by most videos/codec? According to https://wiki.videolan.org/YUV/#I420, "I420 is by far the most common format in VLC. Most video decoders output raw pictures in I420 format". If I add direct translation from that format then maybe it will alleviate the problem.

@fieldofcows I didn't in any way mean it in a way to suggest anything or put pressure on anyone - apologies if that's how it came across. :)

I just meant, from a technical, conceptual point of view, all things equal the video rendering should be able to perform similarly in ES as outside of ES, or at least incrementally similarly.

Should we encode videos differently or is it a rendering tweak? If I'm honest, I believe my videos are encoded like yours. Also, if people resort to Emumovies as a common source, then I'd say optimizing for those would be best as it's more likely that this videos are used by the majority.

I'm thinking of checking how Kodi actually renders videos. Will see what I can find in the coming days.

Thanks for all!
