[Libav-user] [EXTERNAL] Re: "Parser not found" for api call - "av_parser_init"

[Naikar, Vinay]

Hi Paul B Mahol,

Thank you for the information. I have used the example code decoding.c as it is in my main(). Now that you have made me aware of my mistake, could you also help me with the APIs I should use for my purpose. I referred the demuxing_decoding.c file provided in the doc/examples folder of the source code. Should I follow the same code?

Regards
Vinay Naikar

Parser for pcm 16le is not needed, so there is no such parser in code.
