Avoid ffmpeg to lose the flv files keyframes
I use ffmpeg to convert my files, but when I do so, I lose the keyframes metadata from my flv files.
The command I use right now is:
$/usr/local/bin/ffmpeg -i %s -ab 96k -ar 44100 -b 500k -r 25 -f flv %s
How can I avoid ffmpeg to delete the keyframes info?

Solution 1:
Even though the metadata can be lost during any conversion step, it is always possible to regenerate them later.
There are a few tools that can be used to regenerate keyframe informations, including:
- flvmeta (tool that I have developed)
- yamdi
- flvtool2
- flvtool++
- flvmdi
Solution 2:
Try adding the following argument:
-map_meta_data 0:0This should copy the metadata of the first stream of the input file to the first stream of the output file. More information can be found here: http://ffmpeg.org/ffmpeg-doc.html#SEC12
