3.0.0-a5: Option lavcopts: Unknown suboption crf

I was playing around with h.264 transcoding and bandwidth settings to see how it handle low bandwidth and I got this error

Code: Select all

Comparing the command line generated for H.264 on 2.6.5 vs the one on 3.0.0-a5 I found this:

2.6.5 (works)

-lavcopts autoaspect=1:vcodec=libx264:acodec=ac3:abitrate=640:threads=4:o=preset=superfast,crf=20,g=250,i_qfactor=0.71,qcomp=0.6,level=4.1,weightp=0,8x8dct=0,aq-strength=0:keyint=25:vqmax=5:vqmin=2:vrc_maxrate=14000:vrc_buf_size=5000

3.0.0-a5 (fails with the crf error):

-lavcopts autoaspect=1:vcodec=libx264:acodec=ac3:abitrate=640:threads=4:o=preset=superfast,crf=19,g=250,i_qfactor=0.71,qcomp=0.6,level=4.1,weightp=0,8x8dct=0,aq-strength=0:crf=19,:vrc_maxrate=14000:vrc_buf_size=5000

Apparently it's concatenating the "crf" value where the mpeg2 quality settings used to be.

Thanks for reporting this. It will be fixed in a6, and if you want the fix now you can build from the latest code (on Windows you can use our one-click compiler UMSBuilder)
