Playing AAC-LATM format.
Locked
 
|
Hello all,
Basically I'm trying to play a AAC audio stream that is encapsulated using the MPEG-4 LATM-LOAS format. I have one MPEG2 Transport stream, that contains one H264 stream and one AAC-LATM stream. I can demux the H264 and made a patch to allow the demux of the AAC-LATM stream type. However, the AAC decoder plugin (I'm using the FAAD plugin), seems to not handle the LATM format correclty. The pipeline freezes. GST_DEBUG=3 gst-launch-0.10 filesrc location=dumpHomemAranha.ts ! mpegtsdemux name=demux program-number=59224 ! queue ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! xvimagesink demux. ! queue ! faad ! alsasink I can dump the AAC content from the TS using almost the same pipeline GST_DEBUG=3 gst-launch-0.10 filesrc location=dumpHomemAranha.ts ! mpegtsdemux name=demux program-number=59224 ! queue ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! xvimagesink demux. ! queue ! filesink location=audioHomemAranha2.aac The Mplayer can play the output file (audioHomeAranha2.aac) just fine, and it uses the FAAD library. and, if I just play the video content, it is fine: GST_DEBUG=3 gst-launch-0.10 filesrc location=dumpHomemAranha.ts ! mpegtsdemux name=demux program-number=59224 ! queue ! h264parse ! ffdec_h264 ! ffmpegcolorspace ! xvimagesink So, the problem is: How to play one AAC-LATM stream using the FAAD plugin? :) I'll wait any response here, before create a bug in the bugzilla :) Thanks antecipated []s -- Danilo Freire de S.

Hello.
Yes, I tryed :) It seems that the FAAD plugin do not handle the LATM format. The error that it is shown in the debug: gstfaad.c(1265): gst_faad_chain (): /GstPipeline:pipeline0/GstFaad:faad0: failed to parse non-packetized stream []s On Wed, Apr 14, 2010 at 2:11 PM, sudarshan bisht <[hidden email]> wrote: Hi , -- Danilo Freire de S.

Give one more try by inserting aacparse between filesrc and faad .
gst-launch filesrc location=audioHomemAranha2.aac ! aacparse ! faad ! audioconvert ! alsasink .

Nothing =)
Seems that the aacparse does nothing ;) 0:00:00.178302356 3222 0x9b3b2a8 WARN GST_SCHEDULING gstpad.c:4692:gst_pad_get_range:<filesrc0:src> getrange failed unexpected 0:00:00.178330502 3222 0x9b3b2a8 INFO GST_SCHEDULING gstpad.c:4805:gst_pad_pull_range:<aacparse0:sink> pullrange failed, flow: unexpected then, the GstBin says: 0:00:00.178675378 3222 0x99df050 WARN bin gstbin.c:2315:gst_bin_do_latency_func:<pipeline0> failed to query latency []s
