Regarding Mp4muxer

[Sriharsha B]

Hi All..

I m working on mp4muxer.i developed the mp4muxer .the muxer is working
fine but the mp4file generated by mp4 muxer is not interleaved. firstly
muxer is processing  whole audio and then whole video. I m using the
pipeline given below :-


 gst-launch filesrc
location=/home/Gurpreet/inputfilesmp4/Sample_Files/TEST3_960x540_video_2.5mbps.264
! h264parse output-format=0  ! video/x-h264,width=960,
height=540,framerate=25/1 ! queue ! mux. filesrc
location=/home/Gurpreet/inputfilesmp4/Sample_Files/New_Folder/CH1_48000_mono_16bit.pcm
blocksize=2048 !  aacencoder ! mux. mp4mux name=mux ! filesink
location=/home/Gurpreet/outputfilesmp4/44sec.mp4

what is wrong in this ? what could be the reason behind this ? Is there
anything to do with timestamps ?? what should i do for timestamps ?

Thanks
Sriharsha

Do you mean you wrote your own mp4 muxer? If so, then this is simply a
bug in your muxer.

GStreamer comes with a fully functional mp4 muxer, so you'd probably
find it much easier to use that.

Hi All..

I m generating a mov file with aac (MONO) and h264  with muxer(developed by me). the file is being played in VLC fine. But in QUICK TIME only video is coming ....sound is not coming ...When i m checking properties by MOVIE INSPECTOR option in QUICK TIME PLAYER it is showing the aac track and h264 track.

bar in quicktime is moving but no audio coming. What could be the reason ??

Thanks
Gurpreet Singh

Same recommendation as Mike did. Please stop writing own closed muxers
and asks for help here. Use the existing ones and help to improve it.

Or a slightly different way of looking at it, why does the existing mixer not meet your needs?  What are you trying to accomplish by writing your own?

It's difficult for us to speculate on what the causes of the bugs in
your muxer are, since we don't have access to it.

Since GStreamer already has a high quality mp4 muxer, we'd continue to
recommend that you use it. We can't (and wouldn't want to) force that
on you - but if your own code has bugs, we're not going to be terribly
interested in helping you fix them.
