Passing bytes to ffmpeg in python with io

Asked 2021-Jun-07 at 23:03

Sorry, new to stackoverflow

Just wondering if it's possible to pass byte data from io.
I'm trying to extract frames from a gif with ffmpeg then use Pillow to resize it.
I know you can extract frames from a gif with Pillow, but sometimes it butchers certain gifs. So I'm using ffmpeg as a fix.
As for why I'd like the gif to be read from memory is because I'm going to change this so gifs from urls will be wrapped in Bytesio instead of saving.
As for why I have the extra Pillow code, I did successfully get it working by passing an actual filename into the ffmpeg command.

For a single image your code is working fine.
It looks like you are missing proc.wait() at the end and that's it.

For multiple images, you may take a look at my post here.
You may simplify the code, for working with images.

I made few changes to your code, to make it more elegant (I think):

You don't need '-vsync', '0' argument.
I replaced '-' with 'pipe:' (I think it's more clear).
You don't need to set bufsize unless you know that the default is too small.
I removed stderr=SP.PIPE, because I wonted to see the FFmpeg log in the console.
I added proc.wait() after proc.communicate.

The code sample starts by building synthetic GIF image file for testing.

QUESTION

How do you read a Python Traceback error?

Asked 2021-Jun-06 at 10:31

I have run some Python code in Windows 10 and gotten the Traceback error below. Does it mean the string that is supposed to be an int occurs in line 347 of /DeOldify/deoldify/filters.py or line 1943 of /lib/site-packages/PIL/Image.py?

For context, below the traceback error, I've also included the steps that lead to this error (I attempted to colorize a black and white film clip based on the DeOldify Colab https://colab.research.google.com/github/jantic/DeOldify/blob/master/VideoColorizerColab.ipynb but only succeeded at colorizing the first frame as a .jpeg) and the full terminal output.

EDIT: Thanks to @Daweo's response, I discovered the problem was with the arguments I entered into the terminal as indicated by "", line 1. The correct command should have been:
video_path = colorizer.colorize_from_file_name(file_name='my_video.mp4', render_factor=render_factor)

This imply something in filters.py is responsbile for such usage of something from Image.py that raised TypeError.

Concatenate YUVs to generate output YUV using FFMPEG

Asked 2021-May-26 at 19:05

I have 10 yuv input and each yuv is a frame of WxH (ip0_WxH.yuv, ip1_WxH.yuv, ..., ip9_WxH.yuv)

I need to concatenate all 10 to create a final yuv output with all 10 frames in this.

Option 1:

I used below link to do so. But final yuv output is not proper from frame number 2 onwards. Only first frame looks good. From frame number 2, the buffer address of chroma and luma has may be some wrong indexing and hence the display of the picture is wrong.

Try different yuvformat.

As you are using yuv. So use either yuv422p or yuv420p depends upon your input yuv type.

How to loop all videos in a stacked montage until the duration of the longest video

Asked 2021-Apr-27 at 21:35

My objective is to play a 4 video montage of different duration, and loop all the videos until the duration of the longest video. However I couldn't figure out how to do this.

The duration of each of the inputs is:

input1 (Duration: 00:00:00.24)
input2 (Duration: 00:00:01.98)
input3 (Duration: 00:00:04.02)

My objective is to play a 4 video montage of different duration, and loop all the videos until the duration of the longest video. However I couldn't figure out how to do this.

Add -stream_loop -1 before each input except the longest input.

One of my confusion is; when i swap the location of -stream_loop -1 and -i input0.mp4, my output video has the duration of input2.

You're using shortest=1 in xfade. With -stream_loop -1 before input0.mp4 the shortest input becomes input2 (Duration: 00:00:01.98).

ANSWER

Answered 2021-Apr-16 at 09:13

To combine a video stream with an audio stream, you don't need the concat filter. You can simply just map the streams and copy them.

"ffmpeg.exe" -i "demo.mp4" -i "music.mp4" -map 0:v -map 1:a -c copy "demo_music.mp4"

In your case, the audio is longer than the video so the video will effectively "freeze" after it's finished playing.

Since ffmpeg's bug report system does not seem to allow new users (and therefore reports), the only solution I can suggest is avoiding 4.3.x versions and staying in 4.2.3
