Description

Hi,

When I tried to compress an uncompressed avi file with ffmpeg using the latest zeranoe exe it failed with this error: Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height. However, the same command works with a two month old exe (also from zeranoe).

The problem is obvious that in the older version this line appears: Incompatible pixel format 'bgr24' for codec 'libx264', auto-selecting format 'yuv420p'. While in the new version it doesn't consequently, the newer version tries to open libx264 with bgr24 which is incompatible with libx264. I'm not sure what other checks it misses in the new version.

Full output below.

Command:

C:\FFmpeg Video Converter - x64\data\ffmpeg.exe -i "D:\Logs\R43\CondD1\Trial1\DcondR43C1T1CamB.avi"  -profile high -vcodec libx264  -noy  -an -threads 0 "C:\Logs\DcondR43C1T1CamB.mp4"

Older exe output (working):

Status: newclosed

Remove -profile high or change it to -profile high444 if you want bgr24, or add -pix_fmt yuv420 if you want yuv420.

This is the default behavior of x264 if you mix high profile and 4:4:4 output:

$ x264 --output-csp rgb --profile high -o output.mkv input.mkv
x264 [error]: high profile doesn't support 4:4:4

Please reopen this ticket if you believe the default behavior of FFmpeg should be changed.
