Sam460 and 720p video playback

@Spectre660

True, but it will play your test file on the 1st page.

@LiveForIt

Interesting difference in decoding results between AmigaOS 4.1 and MorphOS on the Sam460ex .
The MorphOS version decodes 2.36x faster than the AmigaOS 4.1 version. What could cause such a large difference ?

Very interesting, especially since the libavcodec library version is supposed to be the same. Maybe the following entries in the MorphOS output could be key:

[h264 @ 0x23e7b4f0]Warning: not compiled with thread support, using thread emulation
[aac @ 0x23e7b4f0]Warning: not compiled with thread support, using thread emulation
[mjpeg @ 0x23e7b4f0]Warning: not compiled with thread support, using thread emulation

I'd expect multi-threading in the codecs to only help with multi-core machines.

The only other difference that I found was the following in the AmigaOS version:

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x5a795a48]Could not find codec parameters for stream 2 (Video: mjpeg, none):
unspecified size
Consider increasing the value for the 'analyzeduration' and 'probesize' options

However, I doubt that this would make much of a difference.

Also, you may want to doublecheck that the config files have the same settings. You disabled skiploopfilter in the command line, but there may be other settings in the config file that also matter.

Finally, could the MorphOS version have been compiled with a newer version of gcc with a better optimizer? Or maybe with better compiler settings?

@Hans

Ran the benchmarks again from ram: so no .config files .
OS 4.1 = 468.274
MorphOS 3.9 = 243.830

still almost 2x .

also Ubuntu-Mate 15.10= 311.379

EDIT:
AmigaOS 4.1FE MUI-Mplayer = 411.991

Benchmarks with http://download.blender.org/peach/big ... uck_bunny_720p_stereo.avi

Ubuntu-Mate 15.10 = 469.621s
MorphOS 3.9 = 718.103s
AmigaOS 4.1 Fe = 829.115s

@Spectre660

AmigaOS 4.1FE old MUI-Mplayer = 640.236s
for Big Buck Bunny

@Spectre660

RAM disk can be pretty slow. Try from a fast and modern SFS formatted disk. Could be faster. Especially in the old days, RAM disk was dead slow. A UDMA harddisk was much faster.

MorphOS has done stuff to improve the RAM disk speed, so has OS4. Maybe MOS got it better? But check the mplayer config etc first.

@Deniil

Did everything from from ram to eliminate the config file .

Different version avcodec (FFMPEG)

Older FFMPEG is faster on operating systems with no hardware accelerated video decoding, but support fewer new video formats.

I suggest you take a look at codec version when comparing results, should be present in console output.

Try different version of MPlayer to see what is best.

@Spectre660

RAM handler is slow on AmigaOS, it rally sucks!!!

If you like avoid benchmarking the filesystem, you might use large cache.

@Hans

Quote:

yes might worth trying to compile one without that, and see how that effects speed.

@LiveForIt

Ran Prometheus from harddrive with Mui-Mplayer .

412.584s from harddrive
411.991s from ram:

so no difference there .

Does anybody hear news about the development of DV Player?

@Younghippie

Only this,

http://www.a-eon.com/?news=14-06-2015

Does anybody knows someone who is testing the beta of DV Player
v.0.78?

Almost 5 years later.
Things are looking very intersting .

@Spectre660

What cryptic message is this?
Or still the same old slow?

@Antique

We have lift off.
With a way heavier payload .
4k .

@Spectre660

The real question is not what this can do (since we've known it from about 6 months that "it is coming") but when it will be released.

You've been playing with it from the beginning but we, simple users who will pay for the software, are left over.

For me, with no released date, it's useless speaking of it, sorry.

And since I don't think it will appear before the A1222 is released officially for everyone (in 6 months or more), it's even useless to tease us with cryptic messages.

Emotion used to have a blog ( http://entwickler-x.de/emotion-wip ) on which we can follow the development.

Here, we have nothing except "cryptic messages" of something we all know about and some videos posted on social networks on which we have to guess what is happening.

@K-L

Had bookmarked this old thread and found it while cleaning up old bookmarks.

I can also only speculate also as to when a release will come.

(Hans's blog post regarding working with deadlines comes to mind here .)
https://dl.dropboxusercontent.com/s/0p ... _at_Amiwest_2018.jpg?dl=0

I wonder if the hold up could have anything to do with trying to find some option(s) for X1000 users ?. (Pure speculation on my part).


My role is as a Beta tester. One is not always allowed to be verbose .(I already overstepped earlier in the year).

I have tasked myself to push the video playback on Polaris as far as I can with the machine,components,drivers and software available to me. Interestingly this is an area that the actual Developers of the drivers and Emotion may not have had the time to explore.
