Merge Audio with Video and convert to 3gp format problem.

[kaimerachin]

Hi,

Just purchased the Media Pro Handler, and tested out the code shown at
http://groups.google.com/group/mediasoftpro/browse_thread/thread/e5071a6095e691d4/4b7870ad8a0816f4?lnk=gst&q=attach+audio#4b7870ad8a0816f4,
but having got error.

The changes made are as following:

Changes are made on "_mhandler.CustomCommand" to return the results as
3gp format.

string original_video_path = _mhandler.InputPath + "\
\wearethechampion.3gp";
string audio_track_path = _mhandler.InputPath + "\
\wearethechampion.3gpp";
string final_video_path = _mhandler.InputPath + "\\sample.
3gp";
_mhandler.CustomCommand = " -i " + original_video_path + "
-i " +
audio_track_path + " -ab 128k -ar 22050 -f 3gp " +
final_video_path + "";
string result =_mhandler.Execute_FFMPEG();

Please help or guide me on what i should do,
Thanks in advance.

Dear Customer,

U can achieve attaching audio with video file with final output as .
3gp video by using the following code.

We tested it on ffmpeg build shown below.

www.mediasoftpro.com/downloads/ffmpeg26122.zip

Sample Code:
*****************************************************************

_mhandler.InputPath = RootPath + "\\contents\\original";
_mhandler.OutputPath = RootPath + "\\contents\\flv";

string original_video_path = _mhandler.InputPath + "\\wubai.3gp";
string audio_track_path = _mhandler.InputPath + "\\wubai.3gpp";

string final_video_path = _mhandler.InputPath + "\\wubai_final..
3gp";
_mhandler.CustomCommand= " -i " + original_video_path + " -i " +
audio_track_path + " -s qcif -vcodec h263 -ac 1 -ar 8000 -r 25 -ab
12.2k -y " + final_video_path + "";
_mhandler.Execute_FFMPEG();

****************************************************************************
Check output and give us result.

Normal ffmpeg command will be looking like this
ffmpeg -i wubai.3gp -i wubai.3gpp -s qcif -vcodec h263 -ac 1 -ar 8000 -
r 25 -ab 12.2k -y wubai_final.3gp
