720p video playback stuttering

Reported by: humdinger Owned by: nobody
Priority: normal Milestone: R1
Component: Audio & Video/Codecs Version: R1/Development
Keywords: stuttering video, ffmpeg Cc: HubertNG@…

Description

This is hrev43830 (gcc2hybrid).

While older revisions had no (or very few) problems playing 720p videos in MediaPlayer, they now continually stutter and even stop for a second. Sound runs without stuttering in-sync. This is on a Core2Duo 2ghz, 2gb ram, nvidia 7600 Go (using the nvidia driver).
I can't say when exactly it started, I'll embark on a binary search soon. I happen to have an alpha3 installation handy, where it plays without problems. While it's difficult to assess, "top" suggests a CPU usage of about 25% in alpha3 and 35% in hrev43830.

Attached is the ouput of media_server and MediaPlayer when playing the first few seconds of a clip "720p.mkv".

MediaPlayer output playing 720p video

comment:1 by anevilyak, 12 years ago

If it's recent, it could possibly be related to ffmpeg updates, but an approximate time frame would be really helpful at determining that.

comment:2 by korli, 12 years ago

Media player output already hints at a "Out of memory" error, to be investigated in VideoConsumer::CreateBuffers().

comment:3 by humdinger, 12 years ago

Turns out, it really seems to be ffmpeg related: hrev43826 plays back OK, hrev43830 doesn't. Between those revisions ffmpeg moved into an optional package. But was it updated at that time as well?

comment:5 by korli, 12 years ago

humdinger: I extended the error message in hrev43871. MediaPlayer should display the bitmap bounds it fails to allocate.

comment:6 by humdinger, 12 years ago

I attached the output of a newly built MediaPlayer to this ticket. The gist:

VideoConsumer::CreateBuffers - ERROR CREATING VIDEO RING BUFFER (Index 0 Width 1280 Height 720 Colorspace 8: Out of memory

It seems to be a normal error message when first trying with overlay.

Could you please put a test file somewhere for me to test?

comment:9 by luroh, 12 years ago

Here's one affected file that I normally use for testing: ​http://deathstar.knuttinatoll.net/hammer/bunny-rr.ogv

comment:10 by korli, 12 years ago

Well just tested with gcc2 and gcc4, it works OK.

Looking at your mediaPlayer output again, I noticed the line: "resolve_colorspace: PIX_FMT_NONE => B_RGB32: NULL", which is obviously a problem. FFMpeg should have given something like a YUV colorspace.

Do you use nightlies from haiku-files.org?

comment:11 by humdinger, 12 years ago

I normally build from source, for this binary search I used gcc2hybrid nightly images I downloaded.

comment:12 by humdinger, 12 years ago

I think luroh on IRC was right: MediaPlayer is starving for CPU. Something's not as efficient in ffmpeg since the update in hrev43830. Where in the past the problematic files could be played back with my hardware, now they can't anymore. ffmpeg is single threaded, right? If I disable one CPU, CPU usage goes shortly up to 100%, then the video pauses until the next short spike and so forth.

When both CPUs are activated, their usage are around 50%, so...

I can still play back smaller files, i.e. lower bandwith.

I have the same. For test I use bunny.mp4 with DemoPackage_Video. I was surprised stuttering 720p because on hrev43696 gcc4h 720p (.mkv) work perfectly in MediaPlayer. Then I tested bunny.mp4 on hrev43696 and play good too. Problem is in new revision. I'll try to send a log of the MediaPlayer from both revision.

comment:17 by Hubert, 12 years ago

I wonder... Maybe the problem is somewhere in the patch, which allows new revision play smoothly .rmvb files?

comment:18 by korli, 12 years ago

FFmpeg optional package are updated in hrev43877. Removed --disable-mmx option from the .bep file. Hope this helps!

I'll check this tonight. Could you please also check with gcc4?

comment:22 by luroh, 12 years ago

pure gcc4, hrev43877. Terrible stuttering on my single-core old Athlon64 2GHz. I estimate that maybe 1% of the frames are actually rendered on the screen. Also crashes to gdb when exiting, back trace attached.

comment:23 by korli, 12 years ago

luroh, for gcc4 that's surprising to me, except the crash on exit, which seems to be consistent for both compilers.

I have tried to replicate what we deactivated for GCC2 in the Haiku ffmpeg tree. This doesn't seem to help. What I'll try first is only enable mmx and see if the situation is any better.

comment:24 by luroh, 12 years ago

Just for the record, my gcc4 system is an AMD64 Athlon single-core 2 GHz, 2 GB RAM. The image was built directly to a partition from Ubuntu 11.04, 32-bit, using the latest jam version (jam -q haiku-image). The build was clean (I removed everything in generated/, except for the download folder) and both buildtools and haiku sources were fully updated. I'll be available for more testing tonight.

comment:25 by korli, 12 years ago

hrev43878 brings a GCC2 without SSE, and a fix for crashs on exit.

Humdinger reported a crash with mkv files related to mmx2.

comment:31 by luroh, 12 years ago

hrev43896 gcc2: good news, both jambalaya.mp4 and bunny-rr.ogv now play without visible stuttering or high CPU usage on my laptop, although Terminal still reports "Compiler did not align stack variables..." when launching MediaPlayer.
Now off to test the latest rev with ffmpeg 0.10.2.

comment:32 by luroh, 12 years ago

hrev43901 gcc2: works fine, no noticeable change compared to hrev43896.

comment:33 by luroh, 12 years ago

More testing with hrev43901 on weaker hardware, a T42 laptop (single core 1.7 GHz). jambalaya.mp4 still plays fine while bunny-rr.ogv pegs the CPU at times, causing frame drops and intermittent hangs. Using Xubuntu's default media player 'Parole', the T42 plays bunny-rr.ogv without breaking a sweat, mostly keeping the CPU running in its lowest C-state @ 600 MHz.
Next up is testing an older revision.

comment:34 by luroh, 12 years ago

comment:38 by korli, 12 years ago

Hubert, sorry for that. I've no idea yet on what could expose the behavior you encounter on gcc4.

Could you try with a gcc2 MediaPlayer? It seems it would possible if you're running gcc4h, and it should load the gcc2 ffmpeg plugin. If it doesn't work, could you try with a gcc2 installation?

Replying to luroh:

Using Xubuntu's default media player 'Parole', the T42 plays bunny-rr.ogv without breaking a sweat, mostly keeping the CPU running in its lowest C-state @ 600 MHz.

Have you made sure both are using the same way to display the file? Ie. overlay vs. bitmap drawing? This can make a huge difference, and would be unrelated to the codec being used. One way to test would be to monitor the CPU load when you are on another workspace.

in reply to:  39 comment:40 by luroh, 12 years ago

Have you made sure both are using the same way to display the file?

Good idea. Yes, both Haiku's MediaPlayer and Xubuntu's VLC (...because Parole doesn't have any option to disable overlay) are using overlay by default to play bunny-rr.ogv. Moving to another workspace in these cases scenarios makes no difference when it comes to CPU usage.

On the other hand, if I force Haiku's MP and Xubuntu's VLC to do bitmap drawing, I can see a sharp drop in CPU usage in both OSes when moving to another workspace.

I reproduced the problem but with a heavy 1080p mkv. Seems to be something wrong as CPU isn't full, maybe RAM I/O is saturating.

comment:42 by korli, 12 years ago

Please check with hrev43989. I noticed fewer drops with it.

comment:43 by Hubert, 12 years ago

hrev44016 gcc4h: the same problem :/

When I have a little time (maybe in weekend) I tested gcc2h version.

What revision of Haiku was that log taken with? And what kind of hardware?

in reply to:  46 comment:47 by Premislaus, 12 years ago

Replying to anevilyak:

What revision of Haiku was that log taken with? And what kind of hardware?

hrev44087 gcc4h

Athlon 64 3500+, 1 GB RAM, Radeon HD 5450

Movies are encoded Xvid and AC3 ACM or MP3, AVI.

Slayers has Divx 5 and Vorbis, OGM.

"When installing K-Lite Codec Pack in Windows, I installs the various programs to manage codecs. So I have no artifacts in the displayed film. Simply change the libavcodec for Xvid decoder. Unfortunately, Haiku does not have such functionality. " - ​http://dev.haiku-os.org/ticket/8304

On Windows is well.

Maybe bugs in ffmpeg?

comment:50 by humdinger, 12 years ago

Maybe the whole issue isn't limited to media playback. For a long time I see seconds long freezing when the system is under stress, e.g. jamming a Haiku image. Maybe jua_'s scheduler efforts will help. At last BeGeistert axeld also mentioned some issues with bonefish's kernel changes last year, but I don't have any details... :)

Could potentially also be driver-specific issues, at least I haven't observed pauses like what you describe over here, likely with very different hardware.

Is this still a valid ticket? I tested a variety of 720p videos of different types (.wmv, .mp4 .mov) and all played flawlessly without stuttering or dropping frames, using hrev49046 x86_gcc2.

I can't reproduce anymore, though I don't have the original file anymore. And I also now have a much more powerful CPU (i7-4712MQ@2.3ghz). So, close?

I used the "Pulse" demo to disable all but one core on my system, then played a sequence of 720p videos of different formats. At no time did the cpu load exceed 50%. I'd say close the ticket.
