Hello, Is it possible to add silence to an AAC file without reencoding?
I'm trying to concatenate AAC files with the same encoding (but from different encoders) and it works fine for AAC-LC but HE-AACv1 and HE-AACv2 have frames with the SBR extension and these frames depend on previous frames. I want to get a silence frame with SBR settings that match a certain AAC encoded file so I can add it between concatenated files. This works well right now if I search the file I want to add for frames with low volume and an SBR header (frames that have bs_header_flag set) and add it in between. If I don't add this frame the first few frames from the second file aren't properly decoded and I get "Expected to read %d SBR bytes actually read %d" errors. Thanks. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
