Graphics performance, QTv

Good afternoon!
I have the following problem: performance of my screen graphics while in full screen (ie movie, games) is rather slow. I have CorePlayer installed and it has a major FPS drop when there is a fast picture change in a movie. I've increased alot buffer allocation and put some settings that could ease the situation. I should note, that it happens only to movies that are not encoded before transferring to phone (they remain as is).
Also, I am unable to use QTv option as it gives me sound output only and my screen remains black.
Experience pretty slow graphics in games too.
If you could help me a bit with this problem, I would really appreciate it!
ROM: R2AA008 UK, but had same problem with previous version (R1AA017).

Good Afternoon,
please make sure you read one of the many many threads on this!
coreplayer DOES NOT support hardware playback on our devices at the current time..

Thank you for your reply.
I did a research already and all I found was that there is expected to be "better" support of QTv in v 2.0 of coreplayer. I assume better means that it is still working on current version.
Anyway, QTv is just a mere problem. The main problem when using any other type of video drawing, ie DD.
Also, I did not find much information about having slow graphics on X1. All I found were tweaks (some of which I have applied) and general performance issues, which I don't have.
If you would be so kind to address me to the right topic where the solution/discussion was mentioned, I'd appreciate it.

Best playback now is to convert the video into mp4 using HTC HD convertor (easy to find here) .. and then to play it in media panel or WMP. You can play movies in 800x480 totally smooth like that.
Second option is to use Core Player 1.3 with qTV .. but you will rarely find movie which will play at 100% with no conversion. Anyway CorePlayer is lot slower, which is easy to compare if you let it play those mp4 which play great in WMP.
Then there is TCPMP .. but that will hardly play anything any good.

scroll down or press page 2 (or maybe even page 3 as repeated threads like these push everything back) and you'll see there's at least two threads started by nawfalah, from the last week.

Managed to enable QTv support without decoding.
Thanks for your replies fards, Dr.Sid.

Still give it a try. It's really much better with conversion.

i use itje's touch-it 3.5 rom and im using coreplayer and i havent converted a dvd-resolution movie and it runs buttery smooth on my x1. its file type is .avi

Video stutters in Hardware Mode

When I play avi(maybe other formats too) movies in Stock Video Player or Vital Player in "hardware mode" videos stutter every minute or so.At first I thought that it might be just one movie but I tried few different vids and they all do that.
Anyone else have this problem?Im on latest Bonsai Ext4 rom.Maybe I removed some apk's needed for smooth playback or changed SetCPU settings but I dont think my Epic did that before.
I usualy wouldnt complain but in Vital Player's "software mode" colors look way too bland-like watching vids on lcd,huge difference,lol.
Is this just Bonsai rom bug or what?
UPDATE SOLVED:I set my SetCPU to "performance" mode instead of "conservative" and no more stuttering!Lol,my phone seems to run way smoother now,all these months with my Epic and I dint know what great effect one simple setting can have.
UPDATE 2:Apparently videos only stutter when im downloading files while playing videos,i should have known that.Oh well,no downloading movies while watching movies.
I wonder why playng movies in "Software Mode" on Vital Player dont have that problem,downloading while playing doesnt cause sturrering.

AVI is a container.not a format..common formats used with AVI is xvid and divx...which is it and what version?
Also have you tried the stock media player?
I so far played almost every format imaginable with no issues..but I am on stock..

It was on Xvid and Divx on stock media player.I fixed it by setting SetCPU to "Performance" mode,now no more stuttering and everything is so much smoother!
Dint know that SetCPU modes have greater impact on performance than setting cpu frequencies.
Update:Stuttering occurs only when downloading files while playin videos.If played in "Software mode" stuttering doesnt occur period.

Performance Governor = Max CPU Speed (1GHz in our case).
When using hardware acceleration, the CPU utilization is likely to be less than software mode which results in lower CPU speed in hardware mode than when using software mode. What is likely occuring is in software mode, the CPU is running at a speed fast enough to process the downloaded files and video simultaneously, whereas in hardware mode, the CPU speed is a bit too low to handle both downloading and video which leads to stuttering... and the CPU load isn't high enough to ramp the CPU speed up to the next level.

Poor video Playback.

Hi,
It seems to me that the HTC HD suffers from poor video playback among other performance problems, I didn't know devices this new were affected by this problem as I remember there was a Class Action website concerning some affected devices with poor playback.
I have even used this program which supposedly will encode videos to play well on the HD : http://forum.xda-developers.com/showthread.php?t=467112
Used the factory settings, and video glitched and froze in many spots, also went out of sync many times. Used default bit rate settings. Tried playing in both "Album" and Windows Media Player, same problems
Seeing how the HD plays this video I wouldn't even consider trying Coreplayer with Divx/Xvid.
Is there any drivers/fixes to improve video playback or upgrades in certain ROM/Firmware releases?
Thanks.

that is over all a difficult question, because it consists of many aspects.
first of all, that program uses high bitrates and if it converts to wmv, a poor codec. if you take regular 624 x 352 16:9 xvid files, performance is higher. that's the 2nd thing: you said, after seeing album and wmp perform this bad, you wouldn't even give tcpmp or coreplayer a chance. but actually, they do much better in general, after all, you have way more options to optimize playback depending on bitrate and resolution. you could set the buffering and use options like "override avi framrate based on audio", "prefer lookup tables over arithmetic" and "prefer less buffering over smooth video" to get it to work to your demands.
and of course there are many ways to tweak the performance even further: you can of course try different radio roms and corresponding rilphone versions, different roms (which come with different tweaks cooked in by the respective chefs), or even go further and play around with different drivers, like neo2007's driver pack, or use gfxboost, winmospeed, hdtweak...
i have absolutely no problem playing regular xvid files (as stated above: 624 x 352 xvid, overall bitrate just above 1000kbit/s, 175MB per 22 minutes) absolutely smoothly on my blackstone with audio synced at all points. and that way, i don't even need to convert the videos.
as you can see, it is not done by a single tweak to make them run, maybe you need to switch the codec, the player, the rom and make a lot of settings, but if you want proper video playback, it shouldn't be too much for the result you get. also have a look at the codec info i posted, they are very commonly used.

Hi,
I've tried NEO's driver pack, doesn't seem to help, it was a cab file that I installed, I think it said that those drivers dont improve video playback but are more for improving touchflo and 3d performance? i may be wrong.
That program encoded to AVC I don't think it used WMV (or is it pretty much the same codec?).
Just wondering how do Radio ROMS affect the video playback? I thought the radio rom is for the Phone/GPRS operation?
Also how do tweaks on ROMS affect the playback, I thought it was limited to that the processor simply cannot do the work to make the video play smooth as there doesn't seem to be any dedicated graphics/video chip? Do chefs do tweaks on how the OS uses it's memory? Just wondering what sort of tweaks they are but this might not be a simple answer.
I'm surprised how xvid @ 1000k plays well on your blackstone, hmm. Seems my playback method on coreplayer is "QTV" is that the video accelerator on the Qualcomm Chipset ?
xvid video at 830k at 608 x 400 plays borderline on my blackstone on coreplayer, when Panning on movies it jerks. 1778 frames played, dropped 551.
I would have thought preffer less buffering over smooth video would make the video rougher? going to the description of that option.
I tried ticking those options you suggested, they only slightly improve the playback, however i tried this suggestion from another thread :
"For touch HD, just tick "Disable AVC Deblocking" at advanced tab, "soft drop tolerance" to 0.3 sec, and let other settings defaults. Enjoy your hardware-like video player."
Seems to help the most out of any suggestion but still jerks sometimes.
I'll look into winmospeed to see if it can do anything to speed up my video playback and my device, but not sure how the Qaulcomm CPU copes with overclocking, especially stability and reliability.
What is a safe speed to run at?

which driver pack to use depends on which rom you are using, some roms already come with a driver pack and installing another one makes the device slower rather than faster. the drivers, as you correctly pointed out, generally affect the 3d performance, however, it is about hardware acceleration and some players use hardware acceleration, which should be the same chip, the gpu.
you might be right, the program might encode in avc, just had a brief look at the screenshot, and as you mentioned windows media player, which supports almost no codecs i just assumed, it would go for wmv. as already pointed out, i don't encode my files for the phone. too much work for watching once. instead of re-encoding, i could watch them on the pc instead.
radio roms don't affect video playback directly. they do more than just handling phone calls and wireless communications though, radios are the bridge between the winmo OS and the hardware, so also bluetooth, wi-fi, camera, sound and many more things are influenced. but most of all i mentioned it, because i went through a lot of roms recently, beginning with the latest orange uk stock rom and on every single one of them i experienced an improvement in performance, when i used the newest radio 1.17.25.09 with them, with corresponding rilphone. many cooked roms have specific rilphone versions cooked in, and the radio should match for the entire device to work properly.
as i have never cooked a rom, i certainly can't tell you any of the chefs' secrets, but i assume it takes a lot of work and tweaking, to make new builds and sense versions run properly on this rather slow device. many chefs point out to have compressed a lot of graphic files and optimized cache sizes, pagepool...
some of these tweaks can also be altered with hdtweak.
at the moment i use tcpmp cooked into the energy rom and i believe avc deblocking was ticked by default, or else i would have mentioned it, but i also read before, that it should stay ticked on for better performance.
for winmospeed i mostly set it to level 32 or 33 while playing 3d hd2 games, which are generally very slow on the blackstone. having it permanently set to level 33 causes the phone to freeze sometimes, so that speed seems to be the borderline.
if nothing else helps (and that included trying other roms), you could also disable sense, when you watch videos, if it is so important to you. when watching tv shows or movies, you are not using sense for a rather long time anyway and it really hogs ram and cpu.

agreed.. level 33 = 633mhz is borderline..
a hell of a lot faster than normal 528mhz!
set to level 33 does make the device crash sometimes but not often, i personaly recomend level 33 regardless..
1/10 times it will crash, in my experience its on device first boot after customisation. soft reset and all is ok.
it could be my rom though haha - i joke!

overclocking is completely safe dude, already read up on this before i even tried it when it was released.. so to save you reading, just download it, its worth it

[Q] MIUI 2.1.20 Video Is Buggy - Fix Available?

Hi. I'm currently running MIUI 2.1.20 (see link below)
http://forums.miui.us/showthread.php?13388-MIUI-us-Kindle-Fire-rom-Updated-2-1-20-0xD34D
One problem for me is that I can play streaming videos from the Net and user-uploaded videos in Facebook, but when they play, the video is all choppy, like how a TV is out of tune with like diagonal lines running through it, so it's pretty much un-viewable. The audio plays fine, and the video plays, just can't really make it out at all. So, this happens when I try to watch videos from web-sites that aren't in YouTube & Netflix (those work fine).
Was wondering if there has been any development regarding a fix for this issue in this build of MIUI?
If not, does anyone know if the 2.2.3 ICS build of MIUI addresses this issue? (see link below) It's not listed as a known issue, but I don't want to assume it's fixed before flashing to it.

Thanks for your time & feedback! : ]

I use MX video player for all my videos. You can set it to SW decode and its pretty good about playing all videos without lag.

Right now, the lack of hardware acceleration in the multiple ports of ICS for the Fire prevents HD video playback, and often leaves SD video pretty laggy or choppy. Also, with no native support for Adobe Flash when streaming video, that can degrade the quality as well, if not playing whatsoever. The devs are working to get this resolved, but as it's a really complicated process, it still may be awhile before it's resolved.

Choppy video partially solved

So YouTube drops frames like no tomorrow. This is on stock and the 10 different modded roms and kernels I've tested on. If the "show cpu usage" option is ticked in developer options then video playback is smooth and without dropped frames.
I was doing some investigating regarding choppy video playback in many media players including stock media player, mxplayer and YouTube. If I enable "show cpu usage" in developer options video playback is smooth and cpu usage appears to be typical. When left unchecked video stays choppy. This is a huge flaw with this tablet. Sometimes video playback is smooth on its own, but that is rare. Try watching the first minute of a cg video called "Ruin" on YouTube app to test. Skip to the first minute to see lots of hitching and stuttering.
Was wondering if there were any devs that could help me troubleshoot this problem further. Google doesn't seem to be aware of the terrible frame dropping during video playback on their own apps running on their flagship device. How did this pass Q&A?
