ffpb's Introduction

`ffpb`

Not smart. Not comprehensive. Not guaranteed to work.

ffpb is an FFmpeg progress formatter. It will attempt to display a nice progress bar in the output, based on the raw ffmpeg output, as well as an adaptative ETA timer.

Showcase

(yes, my laptop can't encode shit)

Usage

ffpb is is not even self-aware. Any argument given to the ffpb command is transparently given to the ffmpeg binary on your system, without any form of validation. So if you know how to use the FFmpeg CLI, you know how to use ffpb !

Using as a library

ffpb can be used as a library: use the ffpb.main function:

ffpb.main(argv=None, stream=sys.stderr, encoding=None, tqdm=tqdm):

argv: The arguments to pass to ffmpeg, as an argument list.
stream: The stream to which to write the progress bar and the output messages.
encoding: The encoding of the terminal, used to decode the ffmpeg output. Defaults to locale.getpreferredencoding(), or UTF-8 is locales are not available.
tqdm: The progress bar factory to use. A subclass of tqdm.tqdm is expected. Check althonos/ffpb#19 to see how you can use this to wrap ffpb in your own UI.

Installation

Install from PyPI:

$ pip install --user ffpb

Alternatively, download a development version from the GitHub master branch:

$ pip install https://github.com/althonos/ffpb/archive/master.zip

Or if you use an Arch-based distro, download from the AUR

ffpb's Issues

Thanks, works great

Thanks

Progress bar not showing when converting audio to video.

I run the following command for converting an M4A audio file to an MKV video file, using a single image for the entire video duration:

ffpb -loop 1 -framerate 1 -i "image.png" -i "audio.m4a" -c:v libx264 -preset medium -crf 0 -c:a copy -shortest "video.mkv"

FFPB will show a progress bar for a phase, but for the second phase it will not show.

Does not accept trailing `?` to a map

Conversion failed when -map 0:2? -map 0:3? -map 0:4?—or -map 0:2\? -map 0:3\? -map 0:4\? if running from a Shell script.

Accepted if straight running ffmpeg command, but not when issuing ffpb command.

unable to install no module named 'fcntl' - window 10

No longer woking with FFmpeg 5.1.2

ffpb ceases to work properly with FFmpeg 5.1.2

Progress bar no longer showing up. Instead, something like this is displayed: _filename_: 3612 seconds [00:05, 715.26 seconds/s]

Estimated file size?

Can you maybe add a estimated size of final file during encoding?

ffpb not working for some extensions

Hi. ffpb results in this traceback when I try to convert from .m4a to .mp3.

$ ffpb -i test.m4a test.mp3
Exception in thread STDOUT/ERR thread for pid 8681:

    total=self.duration * self.fps,
TypeError: unsupported operand type(s) for *: 'int' and 'NoneType'

and no progress bar is shown although it does invoke ffmpeg and the output file test.mp3 works as expected.

I also tried to convert from .mp4 to .mkv and the progress bar indeed gets displayed but for some reason it fails for .m4a to .mp3.

Travis failing for missing mp3 file

Travis is failing because the website behind https://www.sample-videos.com/audio/mp3/wave.mp3 is gone.

Can it be replace with any other small mp3 file?

Is it worth it to commit the mp3 file in the repo to remove external dependencies?

Bogus error if ffmpeg can't write

The underlying problem was that FFmpeg can't write output file:

$ touch foo-cc.mp4

advance use for api

Hi
I want to send a progress bar percent and time estimation to my frontend app.
is it possible to get that in another python app and send it via socket to the frontend app?
could you demonstrate how?

Setting log level too low breaks progress bar

When the log level is set to warning or lower, ffpb fails to either a) display a progress bar or b) warn that the log level setting will prevent the progress bar from being displayed. Setting the log level to info, verbose, debug, and trace all correctly display the progress bar.

Here is the command I ran:

ffpb -loglevel error -i $file -c:v libvpx -crf 4 -b:v 5000k -auto-alt-ref 0 ${file%.*}.webm

Unexpected exception: 'utf-8' codec can't decode byte 0xc3 in position 0: unexpected end of data

I keep getting the following error: Unexpected exception: 'utf-8' codec can't decode byte 0xc3 in position 0: unexpected end of data no matter what I do. If I run it directly with ffmpeg, then there's no error whatsoever.

I installed v0.3.0 to check if the error was seen there but it's not. This is a problem with v0.4.0 only.
If there's a way I can debug the code to figure out what's happening.

PS: I installed ffpb through pip3 on Ubuntu 20.04

Does it do correct conversions HH::MM:SS to seconds?

Hi.
Module ffpb/ffpb.py, line 56:
return (int(hours) * 60 + int(minutes)) * 60 + int(seconds)

Should not it be:
return (int(hours) * 3600 + int(minutes)) * 60 + int(seconds)

?
Hmmmm.

Permission to embed your software into FFenmass.

I'm having trouble using ffpb as an import as it does not properly invoke KeyboardException when triggered.

I am asking permission to modify your code from ffpb.py and embed it into FFenmass.

Both FFenmass and ffpb are under MIT license, but I figured would be better to directly ask you.

Compiling into single EXE, sh code issues on Windows machine

When compiling with pyinstaller into single exe, error occurs:
ImportError: sh 1.12.14 is currently only supported on linux and osx. please install pbs 0.110
After installing pbs, it's still presented. Seems like WindowsOS does not like sh code.
There is workaround

But I don't know how to implement it into existing code.

This goes on for as long as the frames are being processed.

ffpb doesn't seem to be able to report on this, and just sits at 0% for the entirety of the first pass:

2021-03-18 19-23-22.mkv:   0%|                                | 0/416340 [03:56<?, ? frames/s]

Which, it doesn't fail to pass any arguments, etc. so it's technically working, it just can't get any info from ffmpeg to display. Is there something that I'm missing that could be passed to enable status on firstpass analysis?

Add an encoding speed after frames/s like 2.64x

Simply the script log:

At this point ffmpeg runs in background, but the only thing on the console I can see is this error message, not the process.
I recommend as a hotfix catching errors at top level, and putting ffmpeg to the controlling terminal instead.

Progress does not show if first input is long

``Progress is printed like the following:
input_file/input_url: 0%| | 0/30480 [00:00<?, ? frames/s]

But when the first input is long, the progress gets printed off-screen.

For instance, I used youtube-dl to extract the constituent URLS for a youtube video to cut it shorter without downloading.
Then, I ran:
ffpb -ss "$start_cut" -i "$url1" -ss "$start_cut" -i "$url2" -t "$time_diff" $video_args out.mp4

And the first url ended up being over 800 characters long, causing the progress to not be shown on the screen.

It would be preferable if the progress were printed to a new line if it would otherwise be printed off-screen.

Thank you.

Does not properly support -ss, -to or -t ffmpeg options

Progress bar does not work as expected if only portion of input file is used because of -ss and -to or -t options.

Cant run ffpb.py, Attribute Error

This is the command i ran:

./ffpb.py -i family.guy.s16e08.720p.web.x264-tbs.mkv -s hd480 -c:v libx264 -crf 23 -c:a aac -strict -2 file.mkv

This is my error:

Traceback (most recent call last):
File "./ffpb.py", line 41, in

Run in Terminal Linux

Sorry to ask, but is it possible run ffpb with ffmpeg with Ubuntu 16.04 Xenial Xerus through Terminal Mode (SSH)? If so, can you explain how to install and run it? And really really sorry again, because I am very noob in Linux OS. Thanks in advance.
