avconv option -c:a copy
I am converting a bunch of videos from FLV to MP4 (for iphone compatibility) and using AAC codec it kept throwing out "invalid audio bitrate" or similar errors. I tried -c:a copy option and it works, but I am wondering if that tells avconv to use the original MP3 codec or just the original audio bitrates/frequencies?
avconv -i input.flv -s 640x480 -b 1248k -vcodec libx264 -acodec aac \
-strict experimental -c:a copy output.mp4
