commercial h264 encoder ?
we have a video sharing site and it needs video encoding, currently we are using ffmpeg for encoding it to h.264; but it cant handle some videos properly and gives audio sync issues and some formats are not supported
is there any commercial encoders out there with api , can be on linux or windows platform |

What you're talking about has nothing to do with the encoder; that's the result of missing decoders or problems in the sync engine. A commercial H.264 encoder has absolutely nothing to do with either of these and will not be able to decode any of your input files at all.

By getting/hiring a developer to patch the code. Since it's open source, it's possible to fix things on your own. If you don't have the resources, try submitting a bug report to FFmpeg.

But first you should make sure that you're using the latest development version of FFmpeg and that you're using it correctly. We may be able to help with that if you post command lines and a sample clip that fails. |

I don't actually want to recommend it, but Rhozet Carbon Coder uses the Mainconcept SDK, which is probably second best H.264 encoder compared to x264.
Carbon Coder can be both amazingly useful and mind bogglingly bad at the same time, and it's definitely not cheap. It might be worth getting a free trial. Their demuxers and muxers can sometimes get the job done. Honestly though, hire an ffmpeg developer... you'll get much better results Derek

As far as I know it does certainly use ffmpeg for a lot of things, but not ALL things - QuickTime for example (handles ProRes etc).
