mencoder and mp4, no bframes?

[Sirber]

Any status of when MP4 made with mencoder will work with bframes?

[bond]

why dont you use ffmpeg?

[Sirber]

I didn't find much infos on how to encode to x264 with it...

[Sharktooth]

you better use mp4box for muxing...

ffmpeg -i input.avs -vcodec h264 -bf 3 -bpyramid 1 -threads 2 ffmpeg.mp4creates a perfect mp4

Example, tweaked "full-version" of 2 pass encoding:
ffmpeg -i video.avs -b 400000 -vcodec h264 -cmp chroma -keyint_min 30 -me_range 16 -deblockalpha -3 -deblockbeta -6 -bf 2 -sc_threshold 40 -qdiff 4 -qmin 10 -qmax 51 -qcomp 0.60 -b_qfactor 1.30 -b_qoffset 1 -i_qoffset 1.40 -i_qfactor 0.71 -qsquish 1 -coder 1 -flags loop -directpred 3 -b_strategy 1 -pass 1 -passlogfile "%temp%\x264.log" -an -refs 1 -trellis 0 -subq 1 -flags2 bpyramid+mixed_refs video.mp4
ffmpeg -i video.avs -b 400000 -vcodec h264 -cmp chroma -keyint_min 30 -me_range 16 -deblockalpha -3 -deblockbeta -6 -bf 2 -sc_threshold 40 -qdiff 4 -qmin 10 -qmax 51 -qcomp 0.60 -b_qfactor 1.30 -b_qoffset 1 -i_qoffset 1.40 -i_qfactor 0.71 -qsquish 1 -coder 1 -flags loop -directpred 3 -b_strategy 1 -pass 2 -passlogfile "%temp%\x264.log" -acodec copy -me umh -refs 6 -subq 6 -trellis 2 -flags2 8x8dct+bpyramid+wpred+mixed_refs+brdo -partitions parti4x4+parti8x8+partp4x4+partp8x8+partb8x8 video.mp4

For some unknown reason, the parti8x8 and i8x8dct option doesnt work, and some options still missing because devs didnt update the code.

I could write a simple batch file for it if someone is interested;)

ffmpeg doesn't allow filtering and subs like mencoder does.

In this page, exemples uses "-of mp4". Can mencoder be compiled with GPAC?

[bond]

why dont you simply feed ffmpeg with an avs script?

I'm trying to build a multi-os encoding GUI :)

I'm trying to build a multi-os encoding GUI :)well i guess you will need to fix mencoder's b-frame handling first ;)

crap :( can I pay you 5$ for it? :D
