Problem in ffmux_mov

[Gurpreet]

Hi All..

I m encoding pcm file with faac and then muxing it with ffmux_mov. I am using this pipeline. file is being played in VLC and QT player.

gst-launch filesrc blocksize=2048  location=/home/Gurpreet/inputfilesmp4/Sample_Files/New_Folder/CH1_48000_mono_16bit.pcm ! audio/x-raw-int, channels=1, rate=48000,  width=16, depth=16, endianness=1234, signed=true ! faac  ! aacparse ! audio/mpeg,rate=48000, channels=1, mpegversion=4, layer=3 ! ffmux_mov ! filesink location=/home/Gurpreet/outputfilesmp4/exp_mov.mov


But Whenever i m setting faac property "outputformat=1"  ( for ADTS Header ) then

gst-launch filesrc blocksize=2048  location=/home/Gurpreet/inputfilesmp4/Sample_Files/New_Folder/CH1_48000_mono_16bit.pcm ! audio/x-raw-int, channels=1, rate=48000,  width=16, depth=16, endianness=1234, signed=true ! faac  outputformat=1 ! aacparse ! audio/mpeg,rate=48000, channels=1, mpegversion=4, layer=3 ! ffmux_mov ! filesink location=/home/Gurpreet/outputfilesmp4/exp_mov.mov

then the generated file is being played in vlc but in QT bar is moving but no audio is coming. what could be the error ?
outputformat=0 is for RAW Aac
outputformat=1 is for ADTS

is this bug in ffmux_mov ? what could be the reason ?

Thanks
Gurpreet

First, you should be using qtmux for this.

I *think* (big emphasis on think) quicktime doesn't support ADTS in .mov files. I remember bumping into this some months ago.

Bugs about this: https://bugzilla.gnome.org/show_bug.cgi?id=598350 and https://bugzilla.gnome.org/show_bug.cgi?id=604925
