Build a 12-byte IV from salt(8) and a big-endian 32-bit counter.

Helper: call SylkE2EE.aesGcm(En|De)crypt(key, iv, aad, data) and return the resulting byte[] (ciphertext+tag for encrypt, plaintext for decrypt). Retu

Decoder-visible canonical form: list of (header + body-with-trailing-zeros-stripped).

Find the next Annex-B start code (00 00 01) at or after `from`. Returns the index of its leading 0x00, or `n` if none. A 4-byte start code (00 00 00 0

Find the first audio track on a list of senders or receivers. * Returns { pcId, trackId } or null if no audio track exists.

Pull encoded packets from the encoder and write them to the muxer. On the first INFO_OUTPUT_FORMAT_CHANGED we add the audio track and start the muxer
