From 26188546b08bcd9a95882aab7aa45ee459925032 Mon Sep 17 00:00:00 2001 From: Jan Schmidt Date: Tue, 25 Jan 2005 15:34:08 +0000 Subject: ext/a52dec/gsta52dec.c: Add some debug output. Check that a discont has a valid time associated. Original commit message from CVS: * ext/a52dec/gsta52dec.c: (gst_a52dec_push), (gst_a52dec_handle_event), (gst_a52dec_chain): Add some debug output. Check that a discont has a valid time associated. * ext/alsa/gstalsasink.c: (gst_alsa_sink_check_event), (gst_alsa_sink_loop): Ignore TAG events. A little extra debug for broken timestamps. * ext/dvdnav/dvdnavsrc.c: (dvdnavsrc_init), (dvdnavsrc_loop), (dvdnavsrc_change_state): Ensure we send a discont to engage the link before we send any other events. * ext/dvdread/dvdreadsrc.c: (dvdreadsrc_init), (dvdreadsrc_finalize), (_close), (_open), (_seek_title), (_seek_chapter), (seek_sector), (dvdreadsrc_get), (dvdreadsrc_uri_get_uri), (dvdreadsrc_uri_set_uri): Handle URI of the form dvd://title[,chapter[,angle]]. Currently only dvd://title works in totem because typefinding sends a seek that ends up going back to chapter 1 regardless. * ext/mpeg2dec/gstmpeg2dec.c: * ext/mpeg2dec/gstmpeg2dec.h: Output correct timestamps and handle disconts. * ext/ogg/gstoggdemux.c: (get_relative): Small guard against a null dereference. * ext/pango/gsttextoverlay.c: (gst_textoverlay_finalize), (gst_textoverlay_set_property): Free memory when done. Don't call gst_event_filler_get_duration on EOS events. Use GST_LOG and GST_WARNING instead of g_message and g_warning. * ext/smoothwave/gstsmoothwave.c: (gst_smoothwave_init), (draw_line), (gst_smoothwave_dispose), (gst_sw_sinklink), (gst_sw_srclink), (gst_smoothwave_chain): Draw solid lines, prettier colours. * gst/mpeg2sub/gstmpeg2subt.c: (gst_mpeg2subt_init): Add a default palette that'll work for some movies. * gst/mpegstream/gstdvddemux.c: (gst_dvd_demux_init), (gst_dvd_demux_handle_dvd_event), (gst_dvd_demux_send_discont), (gst_dvd_demux_send_subbuffer), (gst_dvd_demux_reset): * gst/mpegstream/gstdvddemux.h: * gst/mpegstream/gstmpegdemux.c: (gst_mpeg_demux_send_discont), (gst_mpeg_demux_parse_syshead), (gst_mpeg_demux_parse_pes): * gst/mpegstream/gstmpegparse.c: (gst_mpeg_parse_init), (gst_mpeg_parse_handle_discont), (gst_mpeg_parse_parse_packhead): * gst/mpegstream/gstmpegparse.h: Use PTM/NAV events when for timestamp adjustment when connected to dvdnavsrc. Don't use many discont events where one suffices. * gst/playback/gstplaybasebin.c: (group_destroy), (gen_preroll_element), (gst_play_base_bin_add_element): * gst/playback/gstplaybasebin.h: Make sure we remove subtitles from the same bin we put them in. * gst/subparse/gstsubparse.c: (convert_encoding), (parse_subrip), (gst_subparse_buffer_format_autodetect), (gst_subparse_change_state): Fix some memleaks and invalid accesses. * gst/typefind/gsttypefindfunctions.c: (ogganx_type_find), (oggskel_type_find), (cmml_type_find), (plugin_init): Some typefind functions for Annodex v3.0 files * gst/wavparse/gstwavparse.h: GstRiffReadClass is the correct parent class. --- ext/smoothwave/gstsmoothwave.c | 80 ++++++++++++++++++++++++++++++++++-------- 1 file changed, 66 insertions(+), 14 deletions(-) (limited to 'ext/smoothwave/gstsmoothwave.c') diff --git a/ext/smoothwave/gstsmoothwave.c b/ext/smoothwave/gstsmoothwave.c index 4fd998fd..16d57da6 100644 --- a/ext/smoothwave/gstsmoothwave.c +++ b/ext/smoothwave/gstsmoothwave.c @@ -195,6 +195,27 @@ gst_smoothwave_init (GstSmoothWave * smoothwave) smoothwave->samples_consumed = 0; } +inline guchar * +draw_line (guchar * cur_pos, gint diff_y, gint stride) +{ + gint j; + + if (diff_y > 0) { + for (j = diff_y; j > 0; j--) { + cur_pos += stride; + *cur_pos = 0xff; + } + } else if (diff_y < 0) { + for (j = diff_y; j < 0; j++) { + cur_pos -= stride; + *cur_pos = 0xff; + } + } else { + *cur_pos = 0xff; + } + return cur_pos; +} + static void gst_smoothwave_dispose (GObject * object) { @@ -247,7 +268,6 @@ gst_smoothwave_chain (GstPad * pad, GstData * _data) GstSmoothWave *smoothwave; guint32 bytesperread; gint samples_per_frame; - gint qheight; g_return_if_fail (pad != NULL); g_return_if_fail (GST_IS_PAD (pad)); @@ -290,27 +310,60 @@ gst_smoothwave_chain (GstPad * pad, GstData * _data) gst_adapter_push (smoothwave->adapter, buf); while (gst_adapter_available (smoothwave->adapter) > MAX (bytesperread, samples_per_frame * smoothwave->channels * sizeof (gint16))) { + guint32 *ptr; + gint i; + gint qheight; const gint16 *samples = (const guint16 *) gst_adapter_peek (smoothwave->adapter, bytesperread); - register guint32 *ptr; - gint i; + gint stride = smoothwave->width; /* First draw the new waveform */ if (smoothwave->channels == 2) { + guchar *cur_pos[2]; + gint prev_y[2]; + qheight = smoothwave->height / 4; - for (i = 0; i < smoothwave->width; i++) { - gint16 y1 = (gint32) (samples[i * 2] * qheight) / 32768 + qheight; - gint16 y2 = (gint32) (samples[(i * 2) + 1] * qheight) / 32768 + - (qheight + smoothwave->height / 2); - smoothwave->imagebuffer[y1 * smoothwave->width + i] = 0xff; - smoothwave->imagebuffer[y2 * smoothwave->width + i] = 0xff; + prev_y[0] = (gint32) (*samples) * qheight / 32768; + samples++; + prev_y[1] = (gint32) (*samples) * qheight / 32768; + samples++; + cur_pos[0] = smoothwave->imagebuffer + ((prev_y[0] + qheight) * stride); + cur_pos[1] = + smoothwave->imagebuffer + ((prev_y[1] + + (3 * smoothwave->height / 4)) * stride); + *(cur_pos[0]) = 0xff; + *(cur_pos[1]) = 0xff; + + for (i = 1; i < smoothwave->width; i++) { + gint diff_y = (gint) (*samples) * qheight / 32768 - prev_y[0]; + + samples++; + cur_pos[0] = draw_line (cur_pos[0], diff_y, stride); + cur_pos[0]++; + prev_y[0] += diff_y; + + diff_y = (gint) (*samples) * qheight / 32768 - prev_y[1]; + samples++; + cur_pos[1] = draw_line (cur_pos[1], diff_y, stride); + cur_pos[1]++; + prev_y[1] += diff_y; } } else { qheight = smoothwave->height / 2; - for (i = 0; i < smoothwave->width; i++) { - gint16 y1 = (gint32) (samples[i] * qheight) / 32768 + qheight; - - smoothwave->imagebuffer[y1 * smoothwave->width + i] = 0xff; + guchar *cur_pos; + gint prev_y; + + prev_y = (gint32) (*samples) * qheight / 32768; + samples++; + cur_pos = smoothwave->imagebuffer + ((prev_y + qheight) * stride); + *cur_pos = 0xff; + for (i = 1; i < smoothwave->width; i++) { + gint diff_y = (gint) (*samples) * qheight / 32768 - prev_y; + + samples++; + cur_pos = draw_line (cur_pos, diff_y, stride); + cur_pos++; + prev_y += diff_y; } } @@ -338,7 +391,6 @@ gst_smoothwave_chain (GstPad * pad, GstData * _data) in = smoothwave->imagebuffer; for (i = 0; i < (smoothwave->width * smoothwave->height); i++) { - // guchar t = *in++; *out++ = smoothwave->palette[*in++]; // t | (t << 8) | (t << 16) | (t << 24); } gst_pad_push (smoothwave->srcpad, GST_DATA (bufout)); -- cgit v1.2.1
