• ffmpeg output gives file not found error in python

  20 octobre 2022, par Batuhan Yılmaz

  Trying to build an auto subtitled video generator in Python. But couldn't generate the subtitled video of the input video using ffmpeg. Getting an error saying there is no output.mp4. FileNotFoundError : [Errno 2] No such file or directory : 'C :\Users\batuh\Desktop\auto-multipage\output.mp4'

  


  Can you help me out ? Full code is here : https://github.com/BatuhanYilmaz26/auto-sub-exp/blob/main/pages/02_up3.py

  


  Here's the parts where I used ffmpeg :

  


  def inferecence(loaded_model, uploaded_file, task):
    with open(f"{save_dir}/audio.mp3" , "wb") as f:
            f.write(uploaded_file.read())
        audio = ffmpeg.input(f"{save_dir}/audio.mp3")
        audio = ffmpeg.output(audio, f"{save_dir}/output.wav", acodec="pcm_s16le", ac=1, ar="16k")
        ffmpeg.run(audio, overwrite_output=True)
    if task == "Transcribe":
            options = dict(task="transcribe", best_of=5)
            results = loaded_model.transcribe(f"{save_dir}/output.wav", **options)
            vtt = getSubs(results["segments"], "vtt", 80)
            srt = getSubs(results["segments"], "srt", 80)
            lang = results["language"]
    return results["text"], vtt, srt, lang
    elif task == "Translate":
            options = dict(task="translate", best_of=5)
            results = loaded_model.transcribe(f"{save_dir}/output.wav", **options)
            vtt = getSubs(results["segments"], "vtt", 80)
            srt = getSubs(results["segments"], "srt", 80)
            lang = results["language"]
    return results["text"], vtt, srt, lang
    else:
    raise ValueError("Task not supported")
    
    results = inferecence(loaded_model, input_file, task)
    
    subprocess.run(shlex.split(f"ffmpeg -i {save_dir}/input.mp4 -i {save_dir}/output.wav -i transcript.srt -c:v copy -c:a copy -c:s copy -map 0:a -map 1:v -map 2:s -metadata:s:a:0 language={results[3]} -y {save_dir}/output.mp4"))
    #subprocess.run(shlex.split(f"ffmpeg -i {save_dir}/input.mp4 -vf {save_dir}/transcript.srt -y {save_dir}/output.mp4"))
    with open(os.path.join(os.getcwd(), "output.mp4"), "rb") as f:
                        data = f.read()
                    st.video(data)
                    st.download_button(label="Download Subtitled Video",
                                        data=data,
                                        file_name="output.mp4")

• Adding a bitmap over video using ffmpeg for android

  11 septembre 2014, par Alin

  I am stuck in this area which I am not comfortable at all to work in.

  Here is what I did so far :

  • Made an Ubuntu VirtualBox machine
  • Downloaded latest ffmpeg version which is 2.3.3
  • Compiled ffmpeg to be compatible with armv7-a so in the end I get two folders : include and lib. In include I have the headers and in libs the *.so files (just as in http://www.roman10.net/how-to-build-ffmpeg-with-ndk-r9/)

  

  I have created a new android project and made a jni folder and this is how far I went... Even this, with all the struggle being new to linux and compiling took me almost a week to reach.

  Adding a watermark in ffmpeg I believe it is done on libavfilter ? I have to dig on this matter, however the original ffmpeg I need to translate into my project is :

  ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' output.avi

  As far as I am studying now I need to do inside jni :

  • create a add_watermark.c file in which I need to somehow call the function that does the filter overlay call

  • create Android.mk to load this and the ffmpeg needed libraries

    LOCAL_PATH := $(call my-dir)

    include $(CLEAR_VARS)

    LOCAL_MODULE := add-watermark

    LOCAL_SRC_FILES := add-watermark.c

    LOCAL_LDLIBS := -llog -ljnigraphics -lz

    LOCAL_SHARED_LIBRARIES := libavformat libavcodec libswscale libavutil

    include $(BUILD_SHARED_LIBRARY)

    $(call import-module,ffmpeg-2.3.3/android/armv7-a)

  • create Application.mk

    APP_ABI := armeabi-v7a

    APP_PLATFORM := android-8

  • run ndk-build and use the generated libraries in my android project.

  I really need help on continuing, so every answer is received with great attention and pleasure.

  Later Edit :
  Would it be possible to somehow build ffmpeg.exe as a library and call its main with the exact same parameters as the original exe ? I do not want to run ffmpeg as a standalone executable, but have it integrated within the project. Something like http://www.roman10.net/how-to-port-ffmpeg-the-program-to-androidideas-and-thoughts/ What downsides would this approach have ?
