From 0e1f771d2200d14d298df09c91e14f51e418fd3a Mon Sep 17 00:00:00 2001 From: wm4 Date: Sat, 30 Dec 2017 17:44:03 +0100 Subject: [PATCH] tcp: properly return EOF There is no POSIX error code for EOF - recv() signals EOF by simply returning 0. But libavformat recently changed its conventions and requires an explicit AVERROR_EOF, or it might get into an endless retry loop, consuming 100% CPU while doing nothing. --- libavformat/tcp.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/libavformat/tcp.c b/libavformat/tcp.c index fef0729da6..8773493df1 100644 --- a/libavformat/tcp.c +++ b/libavformat/tcp.c @@ -225,6 +225,8 @@ static int tcp_read(URLContext *h, uint8_t *buf, int size) return ret; } ret = recv(s->fd, buf, size, 0); + if (ret == 0) + return AVERROR_EOF; return ret < 0 ? ff_neterrno() : ret; }
