From 63344337f945843e8f247b3b15fa0f0e7b0f0a7c Mon Sep 17 00:00:00 2001 From: Ed Martin Date: Wed, 10 Mar 2021 21:43:10 +0000 Subject: [PATCH] libavformat/hls: Reset options after open_url_keepalive() fails open_url_keepalive() unsets the options when it uses them, this includes the offsets for the Range: header. When using the HLS tag #EXT-X-BYTERANGE along with multiple files, the range options must be preserved after open_url_keepalive() returns EOF so that the new file can be opened. Failure to do this results in ignoring the #EXT-X-BYTERANGE tag and reading the wrong bytes of the file. To fix it, reset the options before calling io_open() following open_url_keepalive() reaching EOF Reviewed-by: Steven Liu --- libavformat/hls.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/libavformat/hls.c b/libavformat/hls.c index af2468ad9b..d08d00cf24 100644 --- a/libavformat/hls.c +++ b/libavformat/hls.c @@ -677,6 +677,8 @@ static int open_url(AVFormatContext *s, AVIOContext **pb, const char *url, av_log(s, AV_LOG_WARNING, "keepalive request failed for '%s' with error: '%s' when opening url, retrying with new connection\n", url, av_err2str(ret)); + av_dict_copy(&tmp, *opts, 0); + av_dict_copy(&tmp, opts2, 0); ret = s->io_open(s, pb, url, AVIO_FLAG_READ, &tmp); } } else {
