Gstreamer: Encode microphone audio using AAC encode to mp4

Wondering if it is possible to encode using AAC into mp4 container

I have tried using the following

gst-launch-1.0 alsasrc device="hw:0,0" ! "audio/x-raw,rate=48000,channels=2,depth=16" ! queue ! audioconvert ! avenc_aac !  qtmux ! filesink location=audio.mp4

The program runs without a fault but when I inspect the file content, it gives me a null content

However when i run with avimux, the file content gives the encoding and details like lenght of audio

gst-launch-1.0 alsasrc device="hw:0,0" ! "audio/x-raw,rate=48000,channels=2,depth=16" ! queue ! audioconvert ! avenc_aac !  avimux ! filesink location=audio.mp4

Wander what is wrong as I would need AAC encoding (for later rtsp streaming) and need to use mp4 as container and qtmux

thanks

You don't really say what you are doing exactly. But most likely you are missing the -e option for gst-launch-1.0. With that an EOS signal is propagated through the pipleine to correctly finalize the mp4 file. Other file formats are not that picky, but mp4 needs to write a proper index when all samples have been written.
