x264 v2145 64bit bug?
Hi,
First of all I want to say that I have to go to work and I haven't further investigated, but after a quick test with latest x264 v2145 64bit from x264.nl I'm having image corruption as you can see here: I've used the usual settings I've being using since long time ago without any problem with previous versions: Code:
x264-64.exe "sample.m2ts" --bluray-compat --preset veryslow --tune film --force-cfr --b-pyramid strict --open-gop --bitrate 20000 --level 4.1 --aud --nal-hrd vbr --pic-struct --sar 1:1 --vbv-bufsize 30000 --keyint 24 --ipratio 1.1 --vbv-maxrate 38000 --threads auto --slices 4 --thread-input --stats "D:\stats.stats" --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --pass 1 --output NUL x264-64.exe "sample.m2ts" --bluray-compat --preset veryslow --tune film --force-cfr --b-pyramid strict --open-gop --bitrate 20000 --level 4.1 --aud --nal-hrd vbr --pic-struct --sar 1:1 --vbv-bufsize 30000 --keyint 24 --ipratio 1.1 --vbv-maxrate 38000 --threads auto --slices 4 --thread-input --stats "D:\stats.stats" --colorprim "bt709" --transfer "bt709" --colormatrix "bt709" --pass 2 --output "test.264" |

Having reported to mail-list already. I believe it to be a bug in CABAC trellis. Use --trellis 0 to turn trellis off and see if those frames are still corrupt or not.

x264.nl has just updated to r2146 (try F5, if you can't see it yet).

Can someone with broken results (chompy and/or 06_taro) confirm that new 2146 version fix the problem ?
As one of the files modified is an asm x64 specific file, one confirmation of fix should at least be with an x64 version. Last edited by jpsdr; 19th January 2012 at 18:11. |

Wow, the speed increase is great, for my typical PSP encode it's 36% for the 32bit version. Only 11% for the 64bit version but as my Q9650 is only used by three quartes I guess another part of x264 aside from CABAC is the bottleneck there. Probably b-adapt 2 with 8 b-frames (preset veryslow).

I used an uncompressed 480x272 YV12 file off a RAM disk.
The results are: Code:
