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

Hello
I've just got cifs mount work for my galaxy sii.
files can be seen in file expert and video can be played in moboplayer or rockpalyer
but the video performance is really poor. it's very laggy and sometimes freezing.
I am sure it's nothing to do with the players nor the video format since they play local same files very well.
I also found in some other threads complaining about the inefficiency of cifs mounting for streaming.
buzzplayer and xbmc on my ipad stream smb files very well for me, which also proves the problem in android is not due to my network or server.
Does anyone know any methods to improve the streaming performance in android?
Or recommend some player apps that natively support smb streaming like buzzplayer for ios?
Thx
Which kernel do you using?
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.

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.
Is there a kernel out there that fixes the choppy video playback when streaming from HBO Go, Xfinity, Google Play Movies. The only video application that has ever yielded consistent results on my N10 is VUDU. I have tried multiple roms and kernels, yet still get the same results. Are there settings within a certain kernel that is yielding a better experience? Any thoughts would be appreciated.

have you tried forcing max CPU frequency? If I heard right in the past, one user solved his video stutter issues by setting his governor to performance.
As many users dont have problems, I would say any kernel can fix you issue. You just have to find the right settings.
Is anyone else having repeated with their Plex app having problems starting to play files, stuttering when playing files, or app crashes? This has been ongoing for months now and a reinstall of the app does not help.
Changing playback settings in Plex doesn't seem to make much a difference, and I'm on the latest version of the app.
Thanks
