Re-encoding MKV AAC to MKV AC3 causes a delay
Here's my FFMPEG script:
Code:
"X:\Portable Installations\ffmpeg-2014 May 14-git-72dcd48-win64-static\bin\ffmpeg.exe" -i %1 -c copy -absf aac_adtstoasc -vn gain.m4a "X:\Portable Installations\AAC Gain 1.9\aacgain" -r -k -m 0 gain.m4a "X:\Portable Installations\ffmpeg-2014 May 14-git-72dcd48-win64-static\bin\ffmpeg.exe" -i gain.m4a -acodec copy "%~d1%~p1%~n1.aac" "X:\Portable Installations\ffmpeg-2014 May 14-git-72dcd48-win64-static\bin\ffmpeg.exe" -i %1 -i gain.m4a -map 0:v -map 1 -c:v copy -c:a ac3 -ab 2 -ab 128k "%~d1%~p1%~n1.AC3.mkv" del gain.m4a "X:\Daves Folder\Sounds\VideoRedo Completed Sound Short.WAV" pause The problem is that the MKV output by FFMPEG has a 1 minute 5 second delay. There's no audio for the first 1 minute 5 seconds and I can see the delay mentioned in MediaInfo. How can I prevent FFMPEG from causing a delay? |
