ffmpeg Command Lines

[Fishman0919]

I started this thread so people can share some ffmpeg Command Lines that work well for them... and so other can maybe help to improve them

Here's a nice all around command line I use for MPEG2 encoding. Change # to what you need

ffmpeg.exe -i "####.avs" -framerate 23.976 -aspect 16:9 -dc # -g 12 -maxrate 7500k -q:v 2 -b_strategy 2 -brd_scale 2 -bf 2 -profile:v 4 -pass 1 -passlogfile ffmpeg -an -f mpeg2video pass1.m2v

ffmpeg.exe -i "####.avs" -framerate 23.976 -aspect 16:9 -dc # -g 12 -lmin 0.01 -mblmin 1 -qmin 1 -qmax 31 -maxrate 7500k -b:v ####k -bf 2 -pre_dia_size 3 -dia_size 3 -qcomp 0.7 -qblur 0 -preme 2 -me_method dia -sc_threshold 0 -sc_factor 4 -bidir_refine 4 -profile:v 4 -mbcmp satd -precmp satd -cmp satd -subcmp satd -skipcmp satd -pass 2 -passlogfile ffmpeg -an -f mpeg2video pass2.m2v

Thats weird, i was just going to ask if anybody had got ffmprg with x262, i cannot encoder either mpeg2 or h264 when running ffmpeg and x262.

My problem is as follows, from this command line
./ffmpeg -i ../testStreams/Pil.avi -preset faster -vcodec libx264 -x264opts bitrate=1000:vbv-bufsize=2000 -s 720x576 -acodec mp2 -y -f mpegts a.ts

i get

This is the same for mpeg2 and h264

Any ideas?

Really not the idea I was hoping for of this thread.

...But it looks like ffmpeg can't decode your input file. Maybe a bad file or corrupt.

[joolzg]

well thats the weird thing, this was just a copy of one of the non working, i cant get any to work. Even live streams which is my end goal

and this file is one of my test files ive been using for testing x264 for the last year and never had an encoding problem with x264 on this, just x262 in x264 mode

ill try some more
