• VLC command line : RTSP to mp4 file (video + audio)

  8 février 2016, par Dmitriy Gerashenko

  Win 7 x64.

  When I watch this link in VLC player all is fine :

  rtsp ://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov

  When I try to capture link to file and to display :

  • There is video without sound on display.
  • Created file is not playable.

  Command :

  vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"

  There are some errors in log, for example : MPEG4GenericRTPSource Warning: Unknown or unsupported "mode": AAC-hbr. Is it cause of my problems ? How to solve my issue ?

  Complete log (from VLCJ) :

• Gstreamer AAC encoding no more supported ?

  22 juillet 2016, par Gianks

  i’d like to include AAC as one of the compatible formats in my app but i’m having troubles with its encoding.
  FAAC seems to be missing in GStreamer-1.0 Debian-derived packages (see Ubuntu) and the main reason for that (if i got it correctly) is the presence of avenc_aac (Lunchpad bugreport) as a replacement.

  I’ve tried the following :

  gst-launch-1.0 filesrc location="src.avi" ! tee name=t  t.! queue ! decodebin ! progressreport ! x264enc ! mux. t.! queue ! decodebin ! audioconvert ! audioresample ! avenc_aac compliance=-2 ! mux. avmux_mpegts name=mux ! filesink location=/tmp/test.avi

  It hangs prerolling with :

  ERROR libav :0:: AAC bitstream not in ADTS format and extradata missing

  Using mpegtsmux instead of avmux_mpegts seems to work since the file is created but it results with no working audio (with some players it’s completely unplayable).

  This is the trace of mplayer :

  Using the error of the hanging pipeline I’ve finally discovered that avenc_aac should be told in such way to output the data NOT in RAW AAC but in ADTS AAC, the point is that i’ve no idea how to do that with Gstreamer. See here, bottom of the page : FFMPEG Ticket

  At this point since i’ve found no documentation seems right to say we have no support for AAC encoding in GStreamer... which isn’t true, i guess ! (IMHO anyway seems strange the missing of FAAC if AVENC_AAC requires all the time to be set in experimental mode)

  Can someone propose a working pipeline for this ?

  UPDATE

  After some more research i’ve found (via gst-inspect on avenc_aac) what i’m probably looking for but i don’t know how to setup it as needed.
  Have a look at stream-format :

  15 août 2016, par sparks

  I am trying to stream a live video from raspberry pi & pi camera module to web browser.But the video doesn’t play.I am using Nginx-rtmp and ffmpeg to process the video. On the client side i use dash js player trying to play the video but no luck.I see the warning on the terminal

  But i am not sure if this could be the issue. Anybody knows what might be wrong ?I don’t expect a straight answer but i am sure somebody can guide me in the right direction. Thank you in advance. Here is my set up
