ffmpeg-progress-yieldRun an ffmpeg command with its progress yielded.Contents:RequirementsInstallationUsageAs a libraryOn the command lineCaveatsContributorsLicenseRequirementsPython 3.8 or higherffmpeg v3.1 or above fromhttp://ffmpeg.org/installed in your $PATHInstallationpip3 install ffmpeg-progress-yieldOr download this repository, then runpip install ..UsageAs a libraryIn your Python project, import the helper class and runrun_command_with_progress.For more information see theAPI documentation.Example:fromffmpeg_progress_yieldimportFfmpegProgresscmd=["ffmpeg","-i","test/test.mp4","-c:v","libx264","-vf","scale=1920x1080","-preset","fast","-f","null","/dev/null",]ff=FfmpegProgress(cmd)forprogressinff.run_command_with_progress():print(f"{progress}/100")The command will yield the current progress in percent as a float number.run_command_with_progresstakes aduration_overrideargument where you can manually override the duration of the command in seconds. This is useful if your input doesn't have an implicit duration (e.g. if you usetestsrc).If you havetqdminstalled, you can create a fancy progress bar:fromtqdmimporttqdmfromffmpeg_progress_yieldimportFfmpegProgresscmd=["ffmpeg","-i","test/test.mp4","-c:v","libx264","-vf","scale=1920x1080","-preset","fast","-f","null","/dev/null",]ff=FfmpegProgress(cmd)withtqdm(total=100,position=1,desc="Test")aspbar:forprogressinff.run_command_with_progress():pbar.update(progress-pbar.n)# get the outputprint(ff.stderr)You can also quit the command by calling.quit():ff=FfmpegProgress(cmd)forprogressinff.run_command_with_progress():ifprogress>50:ff.quit()breakThis will send a hard quit to the ffmpeg process, and may not wait for it to finish. To quit gracefully, use.quit_gracefully()instead, which sends 'q' to the ffmpeg process, and waits for it to finish.This is probably most useful in asynchronous environments, where you can run the command in a separate thread, and quit it from the main thread (e.g. using aCondition Variable).On the command lineSimply prefix your ffmpeg command withffmpeg-progress-yield:ffmpeg-progress-yieldffmpeg-iinput.mp4output.mp4It will show a progress bar, and once the command is done, show the ffmpeg stderr output.If you want to manually override the duration to, say, 12.5 seconds (e.g. because your input doesn't have an implicit one):ffmpeg-progress-yield--duration12.5ffmpeg-flavfi-itestsrc-t12.5output.mp4CaveatsCurrently, we do not differentiate betweenstderrandstdout. This means progress will be mixed with the ffmpeg log.You can also check outffmpeg-progressfor a similar project with a different feature set.ContributorsWerner Robitza💻WyattBlue💻Kirill Konovalov💻Add your contributionsLicenseThe MIT License (MIT)Copyright (c) 2021-2023 Werner RobitzaPermission is hereby granted, free of charge, to any person obtaining a copy
