I have used Microsoft Expression Encoder to append two videos and this thing works Fine The problem is that when i tried to append videos other than 'wmv' ,it gives exception of FileNot Supported
I searched on google but i was unable to find the solution.
private void button1_Click(object sender, EventArgs e)
{
MediaItem mediaItem1 = null;
Job job = new Job();
job.EncodeProgress += new EventHandler<EncodeProgressEventArgs>(job_EncodeProgress);
int count = 0;
//video url contains all urls of videos
foreach (string x in VideosUrls)
{
if (count == 0)
{
mediaItem1 = new MediaItem(x);
job.MediaItems.Add(mediaItem1);
}
else
{
mediaItem1.Sources.Add(new Source(x));
}
count++;
}
job.OutputDirectory = @"C://videoOutput";
job.Encode();
}
Is there any way using AForge.NET or Microsoft Expression Encoder so i can convert any 'mp4' video to 'wmv' programmatically before appending it with no Audio or quality Loss.
Thanks a lot for reading all Question :)
I would check which edition of Windows Media encoder you have.
The "Express Edition" apparently, "does not support H.264 encoding".
The reality is you need a license for MP4 encoding from MPEG LA. Thats probably why only the paid versions of Expression Encoder support MPEG 4.
Logically, you can't convert from one video/audio format to another without loosing quality. WMV files typically contain video encoded in VC-1 and audio encoded in WMA. But a .mp4 file typically contains h.264 video and AC-3 audio.
So, your final .wmv file will need to contain only video in VC-1 which will mean decoding the h.264 video and encoding it in VC-1. That means quality loss.
VideoLan can tell you the codecs used inside your .mp4 and .wmv files. See this answer .
