From: tolgakaan12 <[email protected]>
The set_encoder_id function in fftools/ffmpeg_mux_init was writing a shortened
encoder tag even when -bitexact flag was set, instead of omitting it entirely
like other formats (flac, mp3, wav) do. This patch makes the function return
early if bitexact flag is set, ensuring no encoder metadata is written.
Fixes ticket #11656.
