From 56df8be6dff017d32218bb3111e6ae6ff1316dec Mon Sep 17 00:00:00 2001 From: Gwenole Beauchesne Date: Tue, 26 May 2015 09:33:57 +0300 Subject: [PATCH 3/6] h264parse: default to byte-stream/nalu format (Annex B). Always default to stream-format=byte-stream,alignment=nalu if avcC format was not detected. This is the natural stream format specified in the standard (Annex.B): a series of NAL units prefixed with the usual start code. https://bugzilla.gnome.org/show_bug.cgi?id=732167 Signed-off-by: Gwenole Beauchesne Signed-off-by: Sreerenj Balachandran --- gst/vaapi/gsth264parse.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-) diff --git a/gst/vaapi/gsth264parse.c b/gst/vaapi/gsth264parse.c index f472a5e..f1ed269 100644 --- a/gst/vaapi/gsth264parse.c +++ b/gst/vaapi/gsth264parse.c @@ -405,7 +405,8 @@ gst_h264_parse_negotiate (GstH264Parse * h264parse, gint in_format, if (!format) format = GST_H264_PARSE_FORMAT_BYTE; if (!align) - align = GST_H264_PARSE_ALIGN_AU; + align = format == GST_H264_PARSE_FORMAT_BYTE ?
