解决vlcandroid播放http视频退出问题

之前用vlc-android播放http视频,程序就自动退出了,尝试用ndk-gdb调试,但是一调试,就报

 

/home/administrator/code/vlc-android/extras/package/android/vlc-android/obj/local/armeabi/gdb.setup:4: Error in sourced command file:
Remote communication error: Connection reset by peer.

到网上也没找到解决方案,最后只用采用在c代码中加入调试打印语句的方式,看究竟是哪里报错,最后跟踪到是调用poll函数引起,

最后采在ffmpeg源码中找到一个poll函数的源码,修改后加入到vlc-android中

int poll(struct pollfd *fds, nfds_t numfds, int timeout)

{

    fd_set read_set;

    fd_set write_set;

    fd_set exception_set;

    nfds_t i;

    int n;

    int rc;

#if HAVE_WINSOCK2_H

    if (numfds >= FD_SETSIZE) {

        errno = EINVAL;

        return -1;

    }

#endif

    FD_ZERO(&read_set);

    FD_ZERO(&write_set);

    FD_ZERO(&exception_set);

    n = -1;

    for(i = 0; i < numfds; i++) {

        if (fds[i].fd < 0)

            continue;

#if !HAVE_WINSOCK2_H

        if (fds[i].fd >= FD_SETSIZE) {

            errno = EINVAL;

            return -1;

        }

#endif

        if (fds[i].events & POLLIN)  FD_SET(fds[i].fd, &read_set);

        if (fds[i].events & POLLOUT) FD_SET(fds[i].fd, &write_set);

        if (fds[i].events & POLLERR) FD_SET(fds[i].fd, &exception_set);

        if (fds[i].fd > n)

            n = fds[i].fd;

    };

    if (n == -1)

        /* Hey!? Nothing to poll, in fact!!! */

        return 0;

    if (timeout < 0)

        rc = select(n+1, &read_set, &write_set, &exception_set, NULL);

    else {

        struct timeval    tv;

        tv.tv_sec = timeout / 1000;

        tv.tv_usec = 1000 * (timeout % 1000);

        rc = select(n+1, &read_set, &write_set, &exception_set, &tv);

    };

    if (rc < 0)

        return rc;

    for(i = 0; i < numfds; i++) {

        fds[i].revents = 0;

        if (FD_ISSET(fds[i].fd, &read_set))      fds[i].revents |= POLLIN;

        if (FD_ISSET(fds[i].fd, &write_set))     fds[i].revents |= POLLOUT;

        if (FD_ISSET(fds[i].fd, &exception_set)) fds[i].revents |= POLLERR;

    };

    return rc;

}
