  • FFmpeg : h264 output broken

    22 juin 2023, par puaaaal

    When I try to encode anything (no -c copy) using the h264 codec, the output is broken in the sense that it can't be played by any standard player (like Windows Media Player). VLC works mostly fine, but also here I had problems, that the video did not align properly. When I use ffplay though, it works fine. When I try to play my source material, which is also encoded with h264, all those methods to play it work fine. (I use mp4 as a container for all these tests)

    


    Command to reproduce :

    


    ffmpeg -f lavfi -i "testsrc=d=10" -vcodec h264 test_h264.mp4


    


    When I use mpeg4 instead, it works fine :

    


    ffmpeg -f lavfi -i "testsrc=d=10" -vcodec mpeg4 test_mpeg4.mp4


    


    Is there something I am missing here, or might this be a bug ?

  • How can I resolve the FileNotFoundError when attempting to convert an MP3 to WAV using ffmpeg in Python ?

    3 juin 2023, par avocado123123

    I have an MP3 file that I want to convert into a WAV file, but no matter how I try writing the code, it keeps raising FileNotFoundError on the MP3 file and warns me about the installation of FFmpeg.

    


    my code :

    


    from pydub import AudioSegment

# Specify the path to the FFmpeg executable
ffmpeg_path = r"C:\Users\תמרה\AppData\Local\ffmpegio\ffmpeg-downloader\ffmpeg\bin\ffmpeg.exe"
AudioSegment.ffmpeg = ffmpeg_path
AudioSegment.ffprobe = ffmpeg_path

# Load the MP3 file
mp3_file = r"C:\Users\תמרה\Tea Time - Ofshane.mp3"
audio = AudioSegment.from_file(mp3_file, format="mp3")

# Export as WAV
wav_file = r"C:\Users\תמרה\Tea Time - Ofshane.wav"
audio.export(wav_file, format="wav")


    


    when running :

    What should I do to make this work ?

  • Pydub : How to ave audio after convert it to aac ?

    4 août 2023, par suvodipMondal

    I am using django admin form to recieve a audio input, and I am trying to convert it into aac format with pydub.&#xA;I have installed ffmpeg in my system and also added pydub and ffmpeg-python as dependencies.

    &#xA;

    Here is the django ModelAdmin :

    &#xA;

    class AudioAdmin(admin.ModelAdmin):&#xA;    fields = (&#x27;file&#x27;, &#x27;bit_rate&#x27;, &#x27;format&#x27;)&#xA;    list_display = (&#x27;id&#x27;, &#x27;file&#x27;, &#x27;bit_rate&#x27;, &#x27;format&#x27;, &#x27;content_type&#x27;)&#xA;&#xA;    def save_model(self, request, obj, form, change):&#xA;        audio_file = form.cleaned_data[&#x27;file&#x27;]&#xA;        _, file_extension = os.path.splitext(audio_file.name)&#xA;        curr_audio = AudioSegment.from_file(file=audio_file, format=file_extension.replace(&#x27;.&#x27;, &#x27;&#x27;))&#xA;        new_audio = curr_audio.export(out_f=audio_file.name, format="aac")&#xA;        obj.file = new_audio&#xA;        obj.save()&#xA;&#xA;

    &#xA;

    I am still getting this error while converting an mp3 file in aac format.

    &#xA;

        raise CouldntEncodeError(&#xA;pydub.exceptions.CouldntEncodeError: Encoding failed. ffmpeg/avlib returned error code: 1&#xA;Command:[&#x27;ffmpeg&#x27;, &#x27;-y&#x27;, &#x27;-f&#x27;, &#x27;wav&#x27;, &#x27;-i&#x27;, &#x27;/var/folders/8g/230x9vx55p7c0bdwx0cmzx9r0000gq/T/tmpxaetjjk0&#x27;, &#x27;-f&#x27;, &#x27;aac&#x27;, &#x27;/var/folders/8g/230x9vx55p7c0bdwx0cmzx9r0000gq/T/tmpa3ae8nn1&#x27;]&#xA;Output from ffmpeg/avlib:&#xA;ffmpeg version 6.0 Copyright (c) 2000-2023 the FFmpeg developers&#xA;  built with Apple clang version 14.0.0 (clang-1400.0.29.202)&#xA;  configuration: --prefix=/usr/local/Cellar/ffmpeg/6.0 --enable-shared --enable-pthreads --enable-version3 --cc=clang --host-cflags= --host-ldflags= --enable-ffplay --enable-gnutls --enable-gpl --enable-libaom --enable-libaribb24 --enable-libbluray --enable-libdav1d --enable-libmp3lame --enable-libopus --enable-librav1e --enable-librist --enable-librubberband --enable-libsnappy --enable-libsrt --enable-libsvtav1 --enable-libtesseract --enable-libtheora --enable-libvidstab --enable-libvmaf --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libxvid --enable-lzma --enable-libfontconfig --enable-libfreetype --enable-frei0r --enable-libass --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable-libspeex --enable-libsoxr --enable-libzmq --enable-libzimg --disable-libjack --disable-indev=jack --enable-videotoolbox --enable-audiotoolbox&#xA;  libavutil      58.  2.100 / 58.  2.100&#xA;  libavcodec     60.  3.100 / 60.  3.100&#xA;  libavformat    60.  3.100 / 60.  3.100&#xA;  libavdevice    60.  1.100 / 60.  1.100&#xA;  libavfilter     9.  3.100 /  9.  3.100&#xA;  libswscale      7.  1.100 /  7.  1.100&#xA;  libswresample   4. 10.100 /  4. 10.100&#xA;  libpostproc    57.  1.100 / 57.  1.100&#xA;Guessed Channel Layout for Input Stream #0.0 : stereo&#xA;Input #0, wav, from &#x27;/var/folders/8g/230x9vx55p7c0bdwx0cmzx9r0000gq/T/tmpxaetjjk0&#x27;:&#xA;  Duration: 00:03:14.72, bitrate: 1411 kb/s&#xA;  Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, 2 channels, s16, 1411 kb/s&#xA;[NULL @ 0x7fe40da072c0] Requested output format &#x27;aac&#x27; is not a suitable output format&#xA;/var/folders/8g/230x9vx55p7c0bdwx0cmzx9r0000gq/T/tmpa3ae8nn1: Invalid argument&#xA;
