We have a few issues here trying to convert flv files that were recorded from live streams into H.264. We have had some success. About 25% of the videos will stream via Wowza after conversion and the rest will not. On the videos that do work the audio and video are way out of sync.
We are using ffmpeg to do the conversion. The original FLV were streamed and record using stream flash video codec.
ffmpeg -i <input_file> -vcodec libx264 -acodec libfaac -ar 48000 -ab 160kb -vpre default -level 30 -y <output_file>
I wanted to automate the process of converting the videos into H.264 so we can stream them to the iPhone and iPad via Wowza. (BTW progressive streaming of the videos works fine to the iphone except for the fact that the audio is out of sync.)
If we can not get this to work automated with ffmpeg does anyone know of a desktop tool I can use to convert these files?
