From 88e5530f59162cf0f31a9cc1c09762ef39a82553 Mon Sep 17 00:00:00 2001 From: Vivia Nikolaidou Date: Fri, 11 Oct 2019 17:25:04 +0300 Subject: [PATCH] tsdemux: Always issue a DTS even when it's equal to PTS Currently tsdemux timestamps only the PTS, and only issues the DTS if it's different. In that case, parsers tend to estimate the next DTS based on the previous DTS and the duration, which can accumulate rounding errors. --- gst/mpegtsdemux/tsdemux.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/gst/mpegtsdemux/tsdemux.c b/gst/mpegtsdemux/tsdemux.c index 9f696f0c3..c28516ef7 100644 --- a/gst/mpegtsdemux/tsdemux.c +++ b/gst/mpegtsdemux/tsdemux.c @@ -3040,7 +3040,8 @@ gst_ts_demux_push_pending_data (GstTSDemux * demux, TSDemuxStream * stream, buffer = gst_buffer_list_get (buffer_list, 0); if (GST_CLOCK_TIME_IS_VALID (stream->pts)) - GST_BUFFER_PTS (buffer) = stream->pts; + GST_BUFFER_PTS (buffer) = GST_BUFFER_DTS (buffer) = stream->pts; + /* DTS = PTS by default, we override it if there's a real DTS */ if (GST_CLOCK_TIME_IS_VALID (stream->dts)) GST_BUFFER_DTS (buffer) = stream->dts; -- 2.34.1
