MPEG-2 TS Muxing
Locked
 
|
Hi
Trying to see if I can get gstreamer to encode a a/v source into a H.264/aac MPEG-2 TS stream. A/V encoding seems to work well, but the TS encoding part seems not to be supported. I'm looking into copy some code from VLC to create a TS mux plugin, but would like to ask first, if anyone else is working on something like that ? As I see it, we need to convert the two ES streams into to PES packet stream into a TS packet stream, which then could use either a UDP output plugin, a http server plugin (when finished) or a RTSP server plugin (if planned). So ES in PES in TS is needed. ES in PES in TS in RTP seems not to be widely used, so thsi is skipped. However, we would also need to create PAT and PMT to make the stream useful for many applications (such as Set Top Boxes not quite as clever as Mplayer).

Fluendo has a MPEG TS muxer. We recently introduced support M2TS 192. https://core.fluendo.com/gstreamer/svn/trunk/gst-fluendo-mpegmux/ Best regards, Julien Moutte, FLUENDO S.A.

Thanks to Ramana and Julien.
A couple of extra questions. a) Any progressed plans on supporting audio/mpeg mpegversion=4 ? (AAC-LC, HE-AAC/AACPLUS) b) Any progressed plans on supporting xvid/mpeg-4 part 2 ? c) Are there any examples of how to use it ? Is it muxed pretty much the same way the avimux works http://gstreamer.freedesktop.org/data/doc/gstreamer/head/gst-plugins-good-plugins/html/gst-plugins-good-plugins-avimux.html Something like gst-launch-0.10 videotestsrc num-buffers=250 \ ! 'video/x-raw-yuv,format=(fourcc)I420,width=320,height=240,framerate=(fraction)25/1' \ ! xvidenc ! queue ! mux. \ audiotestsrc num-buffers=440 ! audioconvert ! 'audio/x-raw-int,rate=44100,channels=2' \ ! lame ! queue ! mux. \ flutsmux name=mux ! filesink location=test.ts Kind regards P.

Just a little remark for others wanting to test or hack. This command
will get you the lot. svn co https://core.fluendo.com/gstreamer/svn/trunk Thanks Peter Maersk-Moller Julien Moutte wrote: > Fluendo has a MPEG TS muxer.

Hi,
I am trying a similar gst pipeline to transcode a file in mp2ts file format with h264 and aac as codecs. Using the following pipeline gst-launch -v filesrc location=/home/kgupta/testflv/limca.flv ! decodebin name=d ! queue ! videorate ! ffmpegcolorspace ! videoscale ! video/x-raw-yuv,height=144,width=176,framerate=\(fraction\)15/1 ! ffenc_h264 ! flutsmux name=mux ! filesink location=limca_aac_h264_faacadts.ts d. ! queue ! audioconvert ! audioresample ! audio/x-raw-int, endianness=1234, signed=\(boolean\)true, width=\(int\)16, depth=\(int\)16, rate=\(int\)16000,channels=\(int\)1 ! faac bitrate=16000 ! mux. Now I am trying to play this file with vlc. The video plays good but no audio. Are there some obvious mistakes in my approach ?? I am using the following versions gst-fluendo-mpegmux-0.10.4 libtsmux-0.3.0 Thanx Kshitij

I meet the same problem as you.
My pipeline is this : gst-launch -v --gst-debug-level=$dbg \ filesrc location=davincieffect_ntsc.264 \ ! h264parse ! mux. \ filesrc location=davincieffect.aac ! aacparse ! mux. \ mpegtsmux name=mux \ ! filesink location=out_264_for_6446.ts When I played the ts file using mplayer, I get the following messages: #################################################################### Playing /home/filesys/opt/gst_dm355/out_264_for_6446.ts.

Hi,
I was able to solve the problem in the follwing way. The aac encoder must produce an adts output stream for this way to work, 1. Modify the mpegtsmux_aac.c to not insert adts header on it's own GstBuffer * flutsmux_prepare_aac (GstBuffer * buf, FluTsPadData * data, FluTsMux * mux) { //guint8 * adts_header = g_malloc0 (7); //GstBuffer * out_buf = gst_buffer_new_and_alloc (GST_BUFFER_SIZE (buf) + 7); GstBuffer * out_buf = gst_buffer_new_and_alloc (GST_BUFFER_SIZE (buf)); gsize out_offset = 0; guint8 rate_idx = 0, channels = 0, obj_type = 0; GST_DEBUG_OBJECT (mux, "Preparing AAC buffer for output"); /* We want the same metadata */ gst_buffer_copy_metadata (out_buf, buf, GST_BUFFER_COPY_ALL); #if 0 /* Generate ADTS header */ obj_type = (GST_READ_UINT8 (GST_BUFFER_DATA (data->codec_data)) & 0xC) >> 2; obj_type++; rate_idx = (GST_READ_UINT8 (GST_BUFFER_DATA (data->codec_data)) & 0x3) << 1; rate_idx |= (GST_READ_UINT8 (GST_BUFFER_DATA (data->codec_data) + 1) & 0x80) >> 7; channels = (GST_READ_UINT8 (GST_BUFFER_DATA (data->codec_data) + 1) & 0x78) >> 3; GST_DEBUG_OBJECT (mux, "Rate index %u, channels %u, object type %u", rate_idx, channels, obj_type); /* Sync point over a full byte */ adts_header[0] = 0xFF; /* Sync point continued over first 4 bits + static 4 bits * (ID, layer, protection)*/ adts_header[1] = 0xF1; /* Object type over first 2 bits */ adts_header[2] = obj_type << 6; /* rate index over next 4 bits */ adts_header[2] |= (rate_idx << 2); /* channels over last 2 bits */ adts_header[2] |= (channels & 0x4) >> 2; /* channels continued over next 2 bits + 4 bits at zero */ adts_header[3] = (channels & 0x3) << 6; /* frame size over last 2 bits */ adts_header[3] |= (GST_BUFFER_SIZE (out_buf) & 0x1800) >> 11; /* frame size continued over full byte */ adts_header[4] = (GST_BUFFER_SIZE (out_buf) & 0x1FF8) >> 3; /* frame size continued first 3 bits */ adts_header[5] = (GST_BUFFER_SIZE (out_buf) & 0x7) << 5; /* buffer fullness (0x7FF for VBR) over 5 last bits*/ adts_header[5] |= 0x1F; /* buffer fullness (0x7FF for VBR) continued over 6 first bits + 2 zeros for * number of raw data blocks */ adts_header[6] = 0xFC; /* Insert ADTS header */ memcpy (GST_BUFFER_DATA (out_buf) + out_offset, adts_header, 7); g_free (adts_header); out_offset += 7; #endif /* Now copy complete frame */ //memcpy (GST_BUFFER_DATA (out_buf) + out_offset, GST_BUFFER_DATA (buf), GST_BUFFER_SIZE (buf)); memcpy (GST_BUFFER_DATA (out_buf) , GST_BUFFER_DATA (buf), GST_BUFFER_SIZE (buf)); return out_buf; } The above code snippet is from flumpegtsmux_aac.c which is exactly same as mpegtsmux_aac.c except the variable names etc. regards Kshitij On Fri, Mar 20, 2009 at 8:54 AM, yangsb <[hidden email]> wrote: > > I meet the same problem as you. > Also , I tried the tsmuxer in gst-plugin-bad-0.10.9 ,but still no audio. > Hope to get some advice. > Thanks > Best regards. > > > Kshitij Gupta-2 wrote: >> >> Hi, >> I am trying a similar gst pipeline to transcode a file in mp2ts file >> format with h264 and aac as codecs.

Hi, flutsmux is running the prepare_aac function only if the incoming AAC data is RAW AAC with an AudioSpecificConfig buffer set on the caps as codec_data. So if your faac encoder generates raw AAC with a codec data this function will be called. If it generates AAC with ADTS headers it won't be called. This muxer works just fine and we are using it in various environments. I think you need to investigate the AAC encoder to see what it generates exactly. Best regards, Julien Moutte, FLUENDO S.A.

In reply to this post by Julien Moutte-2
i am also doing encoding using x264enc encoder and using mpegtsmux muxer for
generating transport stream i could successful to generate ts file and that ts file is easily decoded by VLC but when i am seeing op in TS analyzer there are no video output why ? video source is decklink following is my pipeline /gst-launch-1.0 decklinkvideosrc do-timestamp=true mode=0 connection=1 device-number=0 ! videoconvert ! x264enc tune=zerolatency ! mpegtsmux ! queue ! filesink location=test1.ts -- Sent from: http://gstreamer-devel.966125.n4.nabble.com/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
