From 4ffb2499d35898a773ecbf61b1bf6bfb15e052db Mon Sep 17 00:00:00 2001 From: Stefan Kost Date: Fri, 27 Feb 2009 11:24:37 +0200 Subject: [PATCH] baseparse: revert last change and properly fix Baseparse internaly breaks the semantics of a _chain function by calling it with buffer==NULL. The reson I belived it was okay to remove it was that there is also an unchecked access to buffer later in _chain. Actually that code is wrong, as it most probably wants to set discont on the outgoing buffer. --- gst/aacparse/gstbaseparse.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/gst/aacparse/gstbaseparse.c b/gst/aacparse/gstbaseparse.c index 5f9a949..6d0e7f8 100644 --- a/gst/aacparse/gstbaseparse.c +++ b/gst/aacparse/gstbaseparse.c @@ -864,9 +864,11 @@ gst_base_parse_chain (GstPad * pad, GstBuffer * buffer) parse->priv->pending_events = NULL; } - GST_LOG_OBJECT (parse, "buffer size: %d, offset = %lld", - GST_BUFFER_SIZE (buffer), GST_BUFFER_OFFSET (buffer)); - gst_adapter_push (parse->adapter, buffer); + if (G_LIKELY (buffer)) { + GST_LOG_OBJECT (parse, "buffer size: %d, offset = %lld", + GST_BUFFER_SIZE (buffer), GST_BUFFER_OFFSET (buffer)); + gst_adapter_push (parse->adapter, buffer); + } /* Parse and push as many frames as possible */ /* Stop either when adapter is empty or we are flushing */ @@ -895,7 +897,7 @@ gst_base_parse_chain (GstPad * pad, GstBuffer * buffer) if (parse->priv->discont) { GST_DEBUG_OBJECT (parse, "marking DISCONT"); - GST_BUFFER_FLAG_SET (buffer, GST_BUFFER_FLAG_DISCONT); + GST_BUFFER_FLAG_SET (tmpbuf, GST_BUFFER_FLAG_DISCONT); } skip = -1; -- 2.7.4
