Potential Solutions
- Verify the Codec Compatibility: Check if the FLV file is encoded with a supported codec like H.264 and AAC. Files using older codecs like H.263 may need to be converted first. Use tools like MediaInfo to inspect the file’s codec details.
- Transcode Using Alternative Tools: If Adobe Media Encoder cannot process the FLV file, use HandBrake, VLC Media Player, or FFmpeg to transcode the file into a more compatible format (e.g., MP4 or MOV).
- After conversion, re-import the file into Adobe Media Encoder for further processing.
- Reinstall or Update Adobe Media Encoder: Ensure that you are using the latest version of Adobe Media Encoder. Legacy versions may lack the necessary components for processing certain FLV files.
- Use a Different Workflow: Export the FLV file in a different application that supports the format natively, such as Wondershare UniConverter or older versions of Adobe Flash Professional, before re-importing into Media Encoder.
