Hi, You may have to download the g711 codec lib for a player such as winamp/ vlc then play it.

Re: problem while experimenting with g711enc
mmm... vlc output is [0287] main playlist: nothing to play so I suspect I'm missing an header or something similar... Do you add something at the beginning of the file? I currently just save the encoded output.

Re: problem while experimenting with g711enc
One quick solution is to put 44 bytes wav header at the beginning of the G711 encoded file. VLC will then recognize your clip and play it successfully. We have tested it here. It works with vlc player. Zuber Saiyed Embedded Engineer eInfochips Ltd. Tel. No. +91 79 26563705 Ext. 126 Cell.

would you mind posting the header you're using? On Wed, Jul 22, 2009 at 02:43:12PM +0530, Zuber wrote: One quick solution is to put 44 bytes wav header at the beginning of the G711 encoded file.

Re: problem while experimenting with g711enc
Hi, Header which we have used is as below, view this in hex viewer. It is 44 bytes header. RIFF$ qWAVEfmt For more information on this 44 bytes go through the link given below. You have to modify some of the values from these 44 bytes as per your clip like no. of channels and sampling rate. http://ccrma.stanford.edu/courses/422/projects/WaveFormat/ Zuber Saiyed Embedded Engineer eInfochips Ltd.

Re: problem while experimenting with g711enc
Instead of doing all this work to get it working with VLC/etc, just use Audacity which is an open source audio player It has options to import raw signed 8-bit audio in ulaw/alaw form - this is what I use to playback raw G.711 audio streams, as well as reading WAV files, MP3, etc. Thanks, Jerry Johns Design Engineer Nuvation Research Corp - Canada Tel: (519) 746-2304 ext. 221 www.nuvation.com http://www.nuvation.com/ ___ Davinci-linux-open-source mailing list Davinci-linux-open-source@linux.davincidsp.com http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
