List of new x264 options added to 0.9.5

tokyotech · Post by **tokyotech** » Mon Jan 17, 2011 1:48 am

Can someone please tell me the list of new x264 options added to 0.9.5 which are not backwards compatible with older h264 decoders? For one, I noticed that weighted P frames were turned on by default causing some old media players (namely VLC 0.8.6) to play videos almost 90% gray. So I turned them off and the grayness was gone. Now I noticed that the framerate is not consistent when played back on the old media player. Videos stutter ever so slightly every second or so - bearable but causes headaches after prolonged viewing.

With 0.9.4, I had to do the following to get video to play well in VLC 0.8.6:

Code: Select all

b-adapt=2:rc-lookahead=60:direct=auto:me=umh:vbv-maxrate=2000:vbv-bufsize=4000:trellis=2:8x8dct=0:no-fast-pskip=1:ref=5:merange=24:subq=9:bframes=5:b-pyramid=none

Pasting in the same code with weightp=0 tagged to the end does not produce perfectly smooth videos in 0.9.5. And before anyone asks why I'm still using VLC 0.8.6, it's not for personal use. There's this old browser plugin that's based on this version of VLC that I must use.

Handbrake 0.9.4 incorrectly flagged variable framerate (VFR) streams as constant framerate (CFR). This was corrected in 0.9.5 and seems to cause some issues with degenerate decoders. Try setting an explicit framerate rather than "same as source" in your next encode.

FWIW, 0.9.4 already had weightp enabled. There was a change to weightp 2 in x264 r1555 that breaks a few more players than it used to.

Also, b-pyramid=none is not necessary for 0.9.4: b-pyramid was off by default, and the version of x264 that shipped with 0.9.4 also still had the old b-pyramid (0 or 1; none/strict/normal are not accepted as parameters).
It is required when using 0.9.5, however, if VLC 0.8.6 doesn't support b-pyramid.

Turning off Pyramidal B frames while transcoding in VLC 1.1.5 fixed the flickery problem when played back in old VLC. (Note that there is no hyphen in the parameter name)

#transcode{vb=750, venc=x264{weightp=0, bpyramid=none}, vcodec=h264, acodec=mp3, ab=96, channels=2, threads=2}:duplicate{dst=standard{access=http, mux=asf, dst=127.0.0.1:1234}}

However, doing the same in Handbrake 0.9.5 did not fix the issue. The video was still jittery when played in old VLC. The video jumps a lot during camera pans. It's as though Pyramidal B frames were not even turned off.

mixed-refs=0:8x8dct=0:trellis=2:b-adapt=2:direct=auto:me=umh:no-fast-pskip=1:merange=32:ref=5:subq=9:vbv-maxrate=2000:vbv-bufsize=4000:rc-lookahead=60:bframes=5:b-pyramid=none:weightp=0

Did you try setting a hard framerate as I suggested in my earlier post? It's possible that VLC 0.8.6 does not like VFR encodes.

tokyotech · Post by **tokyotech** » Sat Jan 22, 2011 8:16 am

You are right. VFR was the problem. It seems like most videos are in VFR because I havn't gotten a single one of my transcodes to play smoothly in old VLC with the "same as source' setting.
