[gst-devel] handling multiple audio streams

[Jyoti D]

Hi all,

I am writing an application to transcode TS file into h264 and aac format
and store the transcoded file.
The application works fine with the input files which have one video and
audio stream.
If I have more than 1 audio files I still want to transcode all the audio
streams into aac format and store them in a single file.

Could someone help me to handle ore than 1 audio streams?

I am currently using the below pipeline :

gst-launch-0.10 uridecodebin uri=file://in-file.ts name=d d. ! queue !
audioconvert ! faac ! ffmux_mp4 name=mux ! filesink
location=~/Desktop/h264-aac/out-file.mp4  d. ! queue ! ffmpegcolorspace !
x264enc pass=qual quantizer=16 ref=3 subme=6 analyse=p4x4 me=umh ! mux.


I get the following warning messages while running the above pipeline:

Setting pipeline to PAUSED ...
