[Libav-user] avio_alloc_context api comments

[Anshul]

HI

I was using ffmpeg version 1.2.1

I wanted to use avio_alloc_context api. there was confusion about third
argument of avio_alloc_context
in comment above the api, developers had said that::
" @param write_flag Set to 1 if the buffer should be writable, 0 otherwise."

*but when i debug the code of muxing example,then i found that they
**flags value is 2 *
(  (gdb) print h->flags ; $4 = 2)

*through gdb also it look like 2 *


Breakpoint 3, avio_alloc_context (buffer=0x8f6e980 "\310\347\366\b",
buffer_size=32768, write_flag=2, opaque=0x8f6e940, read_packet=0x805faf7
<ffurl_read>,
    write_packet=0x805fb8a <ffurl_write>, seek=0x805fbef <ffurl_seek>)
at libavformat/aviobuf.c:118
118         AVIOContext *s = av_mallocz(sizeof(AVIOContext));



*Do any one know what should i pass as third argument 1 or 2, if i am
allocating   io of output **
**means i need to write **
*


thanks
