Hi,
ffmpeg 2.8.6 is used to develop application, which reads rtmp stream
and does some video processing. 'AVIOInterruptCB interrupt_callback'
is used to avoid indefinite waiting if there is no avpackets in
network. But it doesn't work, and avformat_open_input() waits forever.
My source code is shown as follows:
static int decodeInterruptCb(void *p)
{
return 1;
}
AVFormatContext *pIfmtCtx;
pIfmtCtx->flags |= AVFMT_FLAG_NONBLOCK;
pIfmtCtx->interrupt_callback.callback = decodeInterruptCb;
pIfmtCtx->interrupt_callback.opaque = NULL;
avformat_open_input(&pIfmtCtx, pInRtmpUrl, NULL, NULL);
callback function is set that intends to return immediately, Why
avformat_open_input() still waits for indefinite time?
Is there something wrong with the usage of ffmpeg lib?
Thanks!

Andrew
I think ticket #5615 have the same/similar problem.
https://trac.ffmpeg.org/ticket/5615
If that is, please bump/update it.
Thanks
