x265 encoding broken since end Feb

[roo1234]

Hello,
I've been using MediaCoder for some particular encodings especially with low res/bitrate content. x265 seems to be killer for that.

I manually update de x265 encoder with the daily releases. Since around 25 February Mediacoder does not encode with updated x265 anymore, returning error 014.

Investigating the console, it seems the reason is parameter --threads was dropped from x265, being replaced by --pools.
I was unable to disable this parameter from MediaCoder. Is there a workaround or update?

Regards,
Roger

Will update this in next release.

X265 - 1.6 is out with lots of performance speed-up on AVX/AVX2 CPUs

I have done some tests with x265.exe:

1920x1080@30fps video game footage, 10 seconds long.
[3sec super fast scene, 3sec slow scene, 4sec medium motion]

1.4+005 = 8min 40 sec
1.5+009 = 7min 57 sec
1.6+038 = 7min 26 sec

x265 x64 8 bit
Core i7 4770 default clock
16GB DDR 3 1600mhz
win 7 x64

Code: Select all

--preset veryslow --no-open-gop --crf 24 --hash 1

Cool. Will update.

x265 1.6+147 = 7min 17 sec

I have tested x265 1.6 +89 too and it was bit slower compared to 1.6+36 [1.6 + 89 = 7min 36 sec] [ebe5e57] so i just deleted it..

And waited for next stable [+147][7f2d929]. Maybe i should have warned you against + 89 but i didnt know that you will update to +89 in 5712

Build 5712 has the latest x265.

[DukeNukemCZ]

you take builds from http://x265.ru/ ? 1.6 +89 is old and x265.ru is not updated well

Newest is 1.6 + 160 and is STABLE
you can find it at http://builds.x265.eu [Built 2015-04-10]

results:
x265 1.6+160 = 7min 11 sec

they really trying hard .. probably because of upcoming NAB Show

Seems a third update in a week is needed.

Hi can you include a fix for x265 not renaming the log file after 1st pass? With latest MediaCoder it seems broken:the temp suffix is not removed :

Code: Select all

x265 [info]: Thread pool created using 12 threads
x265 [info]: frame threads / pool features       : 3 / wpp(17 rows)+pmode+pme
x265 [error]: unable to open file D:\Users\mipam\AppData\Local\Temp\mctemp1430a5
7d3a7014f9.log
x265 [error]: failed to open encoder
