Hi, Thanks for your valuable mail and time as well, Now I stuck, though it encodes in MP2 format but stills there as many problems like:
1. Segmentation fault (Not able to understand) 2. Some noise occurs 3. Encoded data file plays so fast, what we can set here some thing like FPS in video. 4. How to use libavdevice is there any example?? 5. What are the ideal parameters for good quality for MP2/MP3 audio Thanks Peeyush Mishra -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Luca Abeni Sent: Monday, December 15, 2008 1:26 PM To: Libav* user questions and discussions Subject: Re: [libav-user] Problem in live audio encoding through /dev/dsp Markus Rechberger wrote: > On Mon, Dec 15, 2008 at 8:20 AM, Luca Abeni <[email protected]> wrote: >> Peeyush Mishra wrote: >>> Hi all, >>> >>> I am working on a Distance Learning Application , I have encoded raw data >>> into MPEG4 format , But now when I am trying to encode uncompressed audio >>> data coming from /dev/dsp/ but it is not working at all ,,, >> As you do not say what "is not working at all", which kind of problems >> you are experiencing, etc... it is kind of difficult to give suggestions. >> Anyway, your program is almost working here, but it is sampling audio at >> the wrong rate (so, the output file plays too fast). >> > I think he tries to encode too much bytes at once, dividing it by 2 > makes a few chunks > encoding fine although the encoding still crashes.. haven't had a > further look at it yet.. Double looking at it, there are two problems: 1) in_buffer is an array of integers, but the index used for accessing it (frame_byte_size*i) is computed thinking that it is an array of bytes... Fixing this problem, the most subtle crash goes away 2) there is a meaningless "fclose(f)" in the code... Removing it, the other crash is fixed I still think that this program is searching for problems, and that using libavdevice would be a superior solution.
