HOWTO: Install and use the latest FFmpeg and x264

[rulet]

Change:

for file in *.mp4

to:

for file in *.avi

Yes, but I getting an error using this command for avi:

[andrew.46]

Looks like there is some unhappiness with your dimensions:

[scale @ 0x911a7c0] w:1028 h:739 fmt:bgr24 -> w:1028 h:739 fmt:yuv420p flags:0x4
[libx264 @ 0x9102240] height not divisible by 2 (1028x739)

Mind you when I took more attention to such things encoding with x264 demanded that width and height should be divisible by 16 but this is obviously no longer the case. I suspect that you will need to investigate either the scale or the pad filter...

Yea, thank's, seems you are right. I cropped the height of this test video to 738 by the command:

ffmpeg -i input.avi -vf crop=1028:738:0:0 output.avi

And then recoded it to mp4 with that command without errors.

...Is it possible to do cropping and recoding with one command? What it will look with this example?

[FakeOutdoorsman]

...Is it possible to do cropping and recoding with one command?

Yes.

What it will look with this example?

Combining your commands it would look like:

ffmpeg -i input.avi -acodec copy -vcodec libx264 -preset slow -tune film -profile main -crf 29 -vf crop=1028:738:0:0 output.mp4

I removed -threads 0 since that is default now.

[rulet]

It gives an error:

-acodec copy is the problem. MP4 doesn't support PCM audio, or at least ffmpeg doesn't like trying to put it in MP4. Compress it with AAC, MP3, or AC3.

This results in video and no sound.

I am assuming the possible "library mismatch" is causing my issue?

[andrew.46]

When you use '-target ntsc-dvd' by default FFmpeg tries to use mpeg2video video and ac3 sound, looks like the problem might be more likely the conversion to ac3 sound. The 'library mismatch' and 'auto-selecting format 'flt'' warnings are both red herrings, you need to give the rest of the terminal output which unfortunately has been snipped .

Is there a reason that you're not using an encoding preset instead of declaring a bunch of individual options? Example:
