[PATCH] lavf/matroska: Adding support for Opus CodecDelay
by Vignesh Venkatasubramanian 09 Sep '13

09 Sep '13

In order to represent the codec delay accurately in Matroska, a new element CodecDelay has been introduced. It contains the overall delay added by the codec in nanoseconds. This patch adds support for muxing CodecDelay value in the container. Matroska spec for CodecDelay element can be found here: http://matroska.org/technical/specs/index.html#CodecDelay Signed-off-by: Vignesh Venkatasubramanian <vigneshv(a)google.com> --- libavformat/matroska.h | 1 + libavformat/matroskaenc.c | 1 + 2 files changed, 2 insertions(+) diff --git a/libavformat/matroska.h b/libavformat/matroska.h index 7cf423c..2c72d3e 100644 --- a/libavformat/matroska.h +++ b/libavformat/matroska.h @@ -91,6 +91,7 @@ #define MATROSKA_ID_CODECINFOURL 0x3B4040 #define MATROSKA_ID_CODECDOWNLOADURL 0x26B240 #define MATROSKA_ID_CODECDECODEALL 0xAA +#define MATROSKA_ID_CODECDELAY 0x56AA #define MATROSKA_ID_SEEKPREROLL 0x56BB #define MATROSKA_ID_TRACKNAME 0x536E #define MATROSKA_ID_TRACKLANGUAGE 0x22B59C diff --git a/libavformat/matroskaenc.c b/libavformat/matroskaenc.c index 92df6cb..cbfef04 100644 --- a/libavformat/matroskaenc.c +++ b/libavformat/matroskaenc.c @@ -649,6 +649,7 @@ static int mkv_write_tracks(AVFormatContext *s) if (codec->codec_id == AV_CODEC_ID_OPUS) { put_ebml_uint(pb, MATROSKA_ID_SEEKPREROLL, OPUS_SEEK_PREROLL); + put_ebml_uint(pb, MATROSKA_ID_CODECDELAY, codec->delay); } if (mkv->mode == MODE_WEBM && !(codec->codec_id == AV_CODEC_ID_VP8 || -- 1.8.3

[PATCH] TLS OPENSSL SSL_get_error

do_tls_poll with openssl only covers SSL_ERROR_WANT_READ and SSL_ERROR_WANT_WRITE errors returning EIO other cases. I'm figuring out some errors like SSL_ERROR_SSL can be recovered returning EAGAIN. What do you think?

[REFUND-REQUEST] FFmpeg stickers
by Lou Logan 01 Sep '13

01 Sep '13

Hello, My expenses for making and shipping the stickers in US dollars. $41.99 Sticker printing $7.88 Cutting the stickers* $17.21 Shipping most of the stickers to Thilo in Germany from USA Total = $67.08 * Sticker size was limited to business card size by the printer. I ordered the minimum of 500 and cut them in half (due to the aspect of the design, not really to have more stickers) at a local print shop. Thanks. Lou

[PATCH 0/5] Bayer RGB colorspace decoding

This is an rebase and cleanup of some earlier patches that make FFmpeg capable of playing back Bayer RGB colorspace video (known as 'RAW' video in the industry).

[PATCH 0/2] Experimental YouTube protocol support
by Lukasz Marek 30 Aug '13

30 Aug '13

Hi, I made that patch for my purposes, but why not to share it. It bases on perl script available here: https://calomel.org/youtube_wget.html It may require some functional polishing like more advanced stream selection etc, but i prefer to see your attitude about at first. The only concern I have about merging it is that it may stop working without a warning.

[PATCH] remove warning when an mpeg stream starts with a non-I-frame
by Robert Krüger 30 Aug '13

30 Aug '13

The warning as it is now produces a lot of noise for perfectly valid cases, i.e. for streams that start with b-frames (in decoding order) that only reference the first I-frame, which is the case, for example, for typical XDCAM streams.

Thank you Clement, for my research I have to hack into the internal rather than simply writing a filter on image: I ought to output a modified Intra-frame only rather than modifying other interpolated frames to save computations.

Filters and addition/removal on the fly
by JULIAN GARDNER 30 Aug '13

30 Aug '13

I am trying to write a new filter that will when getting stimulus from an external source add/remove other filters from the filterchain on the fly? So my question is, are there any examples which would do this As an example ffmpeg -i src1 -i src2 -filter_complex '[0:v][1:v] overlay' -v:b 1300k overlay_test.ts but with external stimulus to become ffmpeg -i src1 -i src2 -filter_complex '[0:v][1:v] overlay,edgedetect' -v:b 1300k overlay_test.ts and then back again when needed to ffmpeg -i src1 -i src2 -filter_complex '[0:v][1:v] overlay' -v:b 1300k overlay_test.ts This will be a live source and the stimulus will be coming in over a tcp link joolz
