If it helps anyone, I have uploaded a 10 second dump (19 MB) of the stream I'm trying to watch. |

Have you ever tried hardware video acceleration version of mplayer (vdpau/vaapi)? It must be less CPU usage.

Hardware-accelerated playback doesn't appear to work on x86-64. -vo xv, gl, gl2 all give similar results.
Further observations:
* CPU utilization with mplayer is about 75-80% with 32-bit build and 70-73% with 64-bit build (video still runs slow and desyncs)
* -vo null does not have any effect on CPU usage or desync
* -nosound or -ao null has no effect, video still runs slightly faster than half speed, no change in CPU usage

I am running ArchLinux (x86_64) and mplayer-vaapi work just fine. All I need are libav, vdpau-video driver and mplayer-vaapi.
Have a look at:

When I try to play that dump it says:
Code:
h264 @ 0xf056c0]number of reference frames exceeds max (probably corrupt input), discarding one
lots of times with mplayer, which then hangs.
However, it plays fine with 'ffplay', try that.
I think that this message might be correct, the input may be corrupt. It could be a driver problem with the capture card or something. |

I have already tried ffplay, as mentioned earlier in the thread. It maintains sync but stutters due to high CPU consumption.

Did you enable vdpau in ffplay ? when compiling it ? that might help.

Alright, tried building mplayer-vaapi as mentioned earlier in the thread. Builds OK but I get this when I try to run it:
Code:
Playing test.ts.
TS file format detected.

mac.tieu: What versions of mplayer, libva, vdpau_video and Nvidia driver are you using? |

I am using nVidia driver version 195.36.15-2, latest snapshot of libva, vdpau_video, mplayer-vaapi.
You should check for valid path of nvidia_drv_video.so (your is /usr/lib64/va/drivers/nvidia_drv_video.so). There are a utility named 'vainfo' which use to check whether libva installed properly or not.
Code:
$ ./vainfo
libva: libva version 0.31.0
Xlib: extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/local/lib/dri/nvidia_drv_video.so
libva: va_openDriver() returns 0
vainfo: VA API version: 0.31
vainfo: Driver version: Splitted-Desktop Systems VDPAU backend for VA API - 0.6.3
vainfo: Supported profile and entrypoints
VAProfileMPEG2Simple : VAEntrypointVLD
VAProfileMPEG2Main : VAEntrypointVLD
VAProfileH264Main : VAEntrypointVLD
VAProfileH264High : VAEntrypointVLD
VAProfileVC1Simple : VAEntrypointVLD
VAProfileVC1Main : VAEntrypointVLD
VAProfileVC1Advanced : VAEntrypointVLD
You should also pay attention at matching two defines of libva and vdpau-video. Mine is:
Code:
File config.h of vdpau-video:
#define VA_DRIVER_INIT_FUNC __vaDriverInit_0_31
Code:
File va.c of libva:
#define DRIVER_INIT_FUNC "__vaDriverInit_0_31"
Good lucks,
MT. |

Is your user in the video group?
What's your specs with regards to other baselines speeds?
$ glxinfo | grep -i "direct"
$ glxgears -info
(or -printfps depending on distro / version)
$ xvidtune -show
$ ffmpeg -i <video>
$ cat /proc/cpuinfo | grep -i "bogomip"
(while you're trying to play the video, frequency scaling ruins it if you're not maxed)

mac.tieu: I checked the defines you mentioned and they match. I'm using the same versions of everything as you except for the Nvidia driver: 195.36.24
vainfo does the same thing:
Code:
electrode@belphegor:~$ vainfo
libva: libva version 0.31.0-sds6
Xlib: extension "XFree86-DRI" missing on display ":0.0".
libva: va_getDriverName() returns 0
libva: Trying to open /usr/lib64/va/drivers/nvidia_drv_video.so
vdpau_video: error: Assertion failed in file vdpau_driver.c at line 227
Aborted
/usr/lib64/va/drivers/nvidia_drv_video.so exists and is a symlink to vdpau_drv_video.so in the same directory.
Shadow_7: User is in video group. All video and 3D apps run correctly and at reasonable speeds. MPEG-1/2/4 HD video plays without difficulty. CPU scaling is disabled in the kernel (I was using it at one point but found that it screwed up virtualbox).

vdp_device_create_x11 had been failed. It may be due to multiple nvidia library existed. I suggest you to search ' vdp_device_create_x11 error', there are several results related.
Hope that help,

After doing some research, it looks like my card (Geforce 7800 AGP) does not support VDPAU/VA API, so this was all a dead end.
If there are no other suggestions, I give up.
