Duo4k not support .avi files

#!/bin/bash
for i in ./*.avi; do
ffmpeg -i $i -vcodec libx264 -acodec copy -f mpegts $i.ts
done

 

ffmpeg Unknown encoder 'libx264'

Solution https://www.google.r...RPV42041SNrsTJF

 

How to do ffmpeg openpli?

Then I could write a simple conversion plugin.

 

 

What does it mean?

You need to rebuild ffmpeg with enabled libx264 encoder:

--- a/ffmpeg_4.%25.bbappend
+++ b/ffmpeg_4.%25.bbappend
@@ -107,6 +107,7 @@ EXTRA_FFCONF = " \
        --enable-encoder=h263p \
        --enable-encoder=jpeg2000 \
        --enable-encoder=jpegls \
+       --enable-encoder=libx264 \
        --enable-encoder=ljpeg \
        --enable-encoder=mjpeg \
        --enable-encoder=mpeg1video \

And it could be safely added to develop branch I suppose...

ffmpeg: Add libx264 encoder

It might have been removed by @betacentauri due to the size impact. What difference does adding this make?

[blzr]

I'm pretty sure this exact encoder was not removed by choice due to its size - as far as I remember, the first approach was that all ffmpeg encoders, decoders, etc. were enabled by default, then during "operationshrinkingimage" we went the (correct imho) opposite way disabling all of them and enable only these necessarily needed, and so far no one asked for libx264 .
Regarding weight added to ffmpeg my completely wild guess is it'll be rather in kB's than MB's. And we're adding it to develop for now, so...

Ok.
