• Error for android-ndk-r21d and ffmpeg-snapshot

  4 août 2020, par yejafot

  why im getting the below errors.
Am i done any misconfiguration in the build file ?

  


  Can you change it according, im trying to configure for arm64_v8a (.so) file for android jni in my linux machine. Thanks !

  


  Below is my build file.

  i tried all old version of ffmpeg,ndk with different build files but that didnt work so now im trying this latest ffmpeg-snapshot and ndk21

  


• Setting up multiple resolution value in Fast API for transcoding uploaded video files

  23 janvier 2024, par Sanji Vinsmoke

  I created an API for transcoding video files like adaptive bit rate of youtube. I used Fast API. Currently, I am trying to set resolution values for each file. But whenever I am adding multiple resolutions, I am recieving "422 unprocessible entity" error in the Swagger.

  


  Here is my code :

  


  async def transcode_video(input_path, output_folder, res, unique_id, total_files, pbar):
 # Use asyncio for command execution with progress bar
 output_path = os.path.join(output_folder, f"{res}p.m3u8")

 # Calculate the target size
 target_size = calculate_target_size(input_path)

 cmd_duration = f"ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 {input_path}"
 total_duration = float(subprocess.check_output(cmd_duration, shell=True, text=True).strip())

 cmd = (
     f"ffmpeg -i {input_path} -vf scale=-2:{res} -c:a aac -b:a 128k "
     f"-g 50 -hls_time 1 -hls_list_size 0 "
     f"-crf 23 -b:v 100k -fs {target_size} "
     f"-hls_segment_filename \"{output_path.replace('.m3u8', '_%03d.ts')}\" "
     f"{output_path}"
 )

 process = await asyncio.create_subprocess_shell(
     cmd,
     stdout=asyncio.subprocess.PIPE,
     stderr=asyncio.subprocess.PIPE
 )

 while True:
     line = await process.stderr.readline()
     if not line:
         break
     line = line.decode().strip()
     if "time=" in line:
         # Extracting the time progress from FFmpeg output
         time_str = line.split("time=")[1].split()[0]
         current_time = sum(x * float(t) for x, t in zip([3600, 60, 1], time_str.split(":")))
         progress = (current_time / total_duration) * 100
         pbar.update(progress - pbar.n)

 # Wait for the transcoding process to complete
 await process.wait()

 if process.returncode != 0:
     raise HTTPException(status_code=500, detail="Video transcoding failed.")
 pbar.close()

 # Increment the total number of transcoded files
 total_files[0] += 1

@app.post("/transcode/")

     unique_id = str(uuid.uuid4())

     # Log the filename and unique ID
     print(f"Processing file: {file.filename} with unique ID: {unique_id}")

     # Create a folder for the unique ID
     unique_id_folder = os.path.join(OUTPUT_FOLDER, unique_id)
     Path(unique_id_folder).mkdir(parents=True, exist_ok=True)

     # Save the uploaded file
     input_path = os.path.join(UPLOAD_FOLDER, file.filename)
     with open(input_path, "wb") as video_file:
         video_file.write(file.file.read())

     # Check if the file is a valid video file using ffprobe
     try:
         subprocess.run(

  If I provide one resolution it works fine. But if I provide a list of resolutions for all the uploaded videos I am getting error 422.

  I used python 3.8.18. Can you help me please ? I tried with list, object but always getting the error.

  


• Concatenate Movies from Python List using MoviePy or FFmpeg

  24 septembre 2020, par Python_Learner_DK

  I have about 10,000 short videos that I am trying to make several longer videos from.

  



  I've created these videos using MoviePy, but keep getting memory errors when trying to concatenate them back together.

  



  In my code I have an outer loop going through each letter of the alphabet and getting the files that start with that letter.

  



  From the returned video clips I get the length and and strip off the last 3.5 seconds (outro_clip_duration) of the video, and then add it into a Python list clips.

  



  Where I'm stuck is I then want to take this list of trimmed videos and make one long long video from it.

  



  I have all the files, I just need to trim them, concatenate them, and then export them as one.

  



  I've tried many times with different MoviePy attempts and keep getting MemoryErrors so I gave up and took a swing at an ffmpeg solution seen here but it is not working out either.

  



  The latest version of the main part of my code is here :

  



  clips = []
outro_clip = mpy.VideoFileClip('Logo_Intro_w_Stinger_Large.mp4')
outro_clip_duration = outro_clip.duration
for def_image in vid_list_long:
    video_item = mpy.VideoFileClip('F:/sm_My_Video/sm_%s.mp4' % def_image)
    video_item_duration = video_item.duration
    clips.append(ffmpeg_extract_subclip(video_item,0,(video_item_duration - outro_clip_duration), targetname = def_image))

# #Append the outro_clip to the end 
clips.append(mpy.VideoFileClip('Logo_Intro_w_Stinger_Large.mp4',target_resolution = (h,w),audio=True))
slided_clips = [CompositeVideoClip([clip.fx( transfx.crossfadein, transition_seconds)]) for clip in clips]
#added 'method = compose' NEED TO TEST - supposedly removes the weird glitches.
c = concatenate_videoclips(slided_clips, method = 'compose')
c.write_videofile('F:/Extended_Play/%s_Extended_Play_vid.mp4' % letter,fps=23.98)
