Well, my latest effort is pretty close:
ffmpeg 1.0
< Bits/(Pixel*Frame) : 0.152 < Stream size : 1.57 GiB (89%) < Writing library : x264 core 129 r2230 1cffe9f crf=19.0
ffmpeg 0.8
Bits/(Pixel*Frame) : 0.163 Stream size : 937 MiB (88%) Writing library : x264 core 114
bitrate=1200
These are still *completely* different files.
Did you already test 0.8 with a newer x264 or current FFmpeg with older x264?
ffmpeg 1.0 with older x264: Writing library : x264 core 118 Encoding settings : cabac=0 / ref=2 / deblock=1:0:0 / analyse=0x1:0x111 / me=hex / subme=6 / psy=1 / psy_rd=1.00:0.00 / mixed_ref=1 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=0 / cqm=0 / deadzone=21,11 / fast_pskip=1 / chroma_qp_offset=-2 / threads=3 / sliced_threads=0 / nr=0 / decimate=1 / interlaced=0 / bluray_compat=0 / constrained_intra=0 / bframes=0 / weightp=0 / keyint=250 / keyint_min=25 / scenecut=40 / intra_refresh=0 / rc_lookahead=40 / rc=crf / mbtree=1 / crf=22.0 / qcomp=0.60 / qpmin=10 / qpmax=51 / qpstep=4 / ip_ratio=1.40 / aq=1:1.00 Same result; plays about 30 seconds then rebuffers. The ones that play are all variable bit rate; the ones that refuse to play are constant bit rate. How do I set vbr? (I know this is probably a dumb question but I've never had to set it explicitly.) --Yan
