Converting FLV files to MP4 via Post Processing (Orientation Post Processor
Red5 Pro records files as FLV, but many people have asked about how to convert those files easily to MP4 so that more media players can be used to view them. The Red5 Pro
OrientationPostProcessor uses FFMpeg to transcode a supplied FLV into an MP4 with all the recorded orientation events applied to the final video output. This allows the media to be played back without needing to handle orientation metadata. The processor may be used in combination with the S3UploaderPostProcessor to upload converted media once completed; the MP4 will be uploaded to the cloud alongside the FLV. Note that it does take time to convert to MP4, depending on the length of your recording, so the MP4 version will not be immediately available.
