[FFmpeg-devel] [PATCH] avformat/hls.c:If custom IO is used, Don`t keepalive.

[He Lei]

The URLContext of the aviocontext is null when custom IO is used, If  keepalive, that will cause the assertion to fail

 592 static int open_url_keepalive(AVFormatContext *s, AVIOContext **pb,
 593                               const char *url)
 594 {
 595 #if !CONFIG_HTTP_PROTOCOL
 596     return AVERROR_PROTOCOL_NOT_FOUND;
 597 #else
 598     int ret;
 599     URLContext *uc = ffio_geturlcontext(*pb);
 600     av_assert0(uc);
 601     (*pb)->eof_reached = 0;
 602     ret = ff_http_do_new_request(uc, url);
 603     if (ret < 0) {
 604         ff_format_io_close(s, pb);
 605     }
 606     return ret;
 607 #endif
 608 }
