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!
Regards
Andrew
