• 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
codec_tag=0x6134706d
sample_fmt=fltp
sample_rate=44100

max_bit_rate=N/A
bits_per_raw_sample=N/A
nb_frames=378
nb_read_frames=N/A
nb_read_packets=378


  


  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
channels=2
channel_layout=stereo
bits_per_sample=0
initial_padding=0
id=0x2
r_frame_rate=0/0
avg_frame_rate=0/0
time_base=1/44100
start_pts=1764
start_time=0.040000
duration_ts=436480
duration=9.897506
bit_rate=111733
max_bit_rate=N/A
bits_per_raw_sample=N/A
nb_frames=427
nb_read_frames=N/A
nb_read_packets=427
extradata_size=5


  


  Why ?

  


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

  


  ffprobe version 6.1.1-3ubuntu5 Copyright (c) 2007-2023 the FFmpeg developers

  libpostproc    57.  3.100 / 57.  3.100


  


  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.

  


  [streams.stream.1]

• ffmpeg.wasm - How to do literally anything with a blob url

  24 novembre 2024, par SeriousLee

  I'm using the ffmpeg.wasm for the first time and I can't get anything working, beyond loading it. I have this function that does nothing in particular (I got it from the vite + react example in the docs, slightly modified) and all I want to do is pass it a blob URL like this blob:http://localhost:5173/c7a9ea7c-aa26-4f4f-9c80-11b8aef3e81f and run through the function and have it give me anything back. But instead, it hangs on the ffmpeg.exec command and never completes. And yes, I've determined that the input blob does work - it's an 8MB, 12-second long mp4 clip.

  


  Here's the function :

  


      const processOutputVideo = async (videoURL) => {
      const ffmpeg = ffmpegRef.current;

      await ffmpeg.writeFile("input.mp4", await fetchFile(videoURL));
      await ffmpeg.exec(["-i", "input.mp4", "output.mp4"]);

      const fileData = await ffmpeg.readFile("output.mp4");
      const blob = new Blob([fileData.buffer], { type: "video/mp4" });
      const blobUrl = URL.createObjectURL(blob);

      return blobUrl;
    };


  


  And here's the ffmpeg logs from my terminal.

  And it just hangs there. When I use the example video URL from the official example (https://raw.githubusercontent.com/ffmpegwasm/testdata/master/video-15s.avi), it doesn't hang and it completes the function and returns me a blob URL in the same format as that first blob URL I showed you guys and this is what the ffmpeg output looks like in my console in that case :

  Where am I going wrong, what should I convert my input blob into ? And just FYI, ChatGPT has been completely garbage at helping me solve this lmao.
