• ffprobe newer version detect audio codec incorrectly

  16 janvier, par alancc

  I find a strange problem.

  


  I have a test video with h264 video codec and aac audio codec. It is at https://drive.google.com/file/d/1YAyz5cO0kb9r0MgahCpISR4bZ_1_n8PL/view?usp=sharing

  


  I build a ffmpeg version by myself, its version is :

  


  ffprobe version 7.0.2 Copyright (c) 2007-2024 the FFmpeg developers
  built with gcc 14.1.0 (Rev3, Built by MSYS2 project)
  configuration: --enable-shared
  libavutil      59.  8.100 / 59.  8.100
  libavcodec     61.  3.100 / 61.  3.100
  libavformat    61.  1.100 / 61.  1.100
  libavdevice    61.  1.100 / 61.  1.100
  libavfilter    10.  1.100 / 10.  1.100
  libswscale      8.  1.100 /  8.  1.100
  libswresample   5.  1.100 /  5.  1.100


  


  I then use ffprobe to get its info :

  


  ffprobe -v quiet -print_format ini -show_streams -show_packets test_h264.mp4 > test_h264.ini


  


  Then I get an ini file which shows the audio codec as MP2 :

  


  [streams.stream.0]
index=0
codec_name=mp2
codec_long_name=MP2 (MPEG audio layer 2)
profile=unknown
codec_type=audio
codec_tag_string=mp4a

  Another developer he uses his version of ffprobe :

  


  ffprobe version 2023-02-22-git-d5cc7acff1-full_build-www.gyan.dev Copyright (c) 2007-2023 the FFmpeg developers  


  


  Based on the year, my version(2024) should be newer than his(2023), but his version of ffprobe can get the audio codec properly :

  


  [streams.stream.1]
index=1
codec_name=aac
codec_long_name=AAC (Advanced Audio Coding)
profile=LC
codec_type=audio
codec_tag_string=mp4a
codec_tag=0x6134706d
sample_fmt=fltp
sample_rate=44100

  Why ?

  


  I also tried a ffprobe version on ubuntu with the following version :

  It will detect the audio as aac properly, but with different parameters, for example, bit_rate is 111733(developer) but 110399(ubuntu). But this parameter comes from the same file so should be the same.

• Converting HLS Stream to stream supported by old radio

  29 novembre 2024, par Alberto Faenza

  I have an old internet radio that does not support HLS streams.
Therefore I cannot listen to my favourite radio at this url :
https://streamcdnf31-4c4b867c89244861ac216426883d1ad0.msvdn.net/radiodeejay/radiodeejay/master_ma.m3u8

  


  I found a solution using a paid software https://minimradio.com/ which is based on minimserver and minimstreamer.

  


  This solution works if I install mininmserver and minimstreamer on a local computer and use the internet radio to point to the converter stream but I will have to pay if I want to use this.

  


  Checking the documentation of minimradio and ministreamer I can see the following :

  


  *Some internet radios can play the previous AAC ADTS streams but can't play these new HLS streams
...

  


  If the network stream URL points to an HLS .m3u8 master playlist or media playlist file, MinimStreamer reads this file and uses the HLS protocol to read the stream audio data and send it to the music player as a conventional HTTP stream. This makes the stream playable on music players that don't support the HLS protocol. The audio data in the stream must be encoded in AAC format.*
and not a single destination receiver I should use a streaming (broadcasting) server. What can I use to do that ?

  


  My question is the following :
Is there a way to replicate what minimstreamer is doing using ffmpeg ?
I have tried this :

  


  


  ffmpeg -re -i https://streamcdnf31-4c4b867c89244861ac216426883d1ad0.msvdn.net/radiodeejay/radiodeejay/master_ma.m3u8 -c copy -listen 1 -f mpegts http://192.168.1.9:10000

  


  


  which is playing corrctly in local vlc on the same computer. But when I stop VLC is got this error in ffmpeg :

  What is the correct way to stream this one locally in order to be listened in my internet radio ?
Shall I use ffmpeg or can be done directly with ngnix ? Or shall I use both ?
