Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

Ajouter notes et légendes aux images
7 février 2011, parPour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

Use ffmpeg to pan right over an image and then pan left to the original location
4 février 2024, par user1517922I'm using this command to pan to the right for 5 seconds on an image (like a 1080x1080 window moving across a larger image, 500px from the top) :


ffmpeg -loop 1 -r 30 -i image.jpg -vf crop=w=1080:h=1080:x=n:y=500 -frames:v 150 -pix_fmt yuv420p -preset fast -crf 30 video.mp4

I'd like to pan back to the left for 5 seconds to end up at the same spot.


The desired affect is when the video is on loop the square window pans right for 5 seconds then back left for 5 seconds then repeats, smooth and without flicker.


I suspect I need to use zoompan, but I haven't had success trying that.

How to convert multiple jpg images to MP4 format using FFmpeg ?
30 janvier 2024, par PDLAOZEI- 

-
I first used the FFmpeg command line to implement this function.

ffmpeg -framerate 1 -pattern_type glob -i "./image/*.jpg" -c:v libx264 -crf 25 -vf format=yuv420p -movflags +faststart test.mp4

-
Then I use FFmpeg's api to convert multiple jpg into MP4 format, the process is probably.








- 

- Find the AV_CODEC_ID_MPEG4 encoder.
- Turn on the encoder.
- Set video stream parameters.
- Open the output file.
- Write file header.
- Allocate image frame rate and buffer.
- Write each jpg image to the video (write in a loop).
7-1. read jpg image.
7-2. Find video stream information.
7-3. Decoded image frame.
7-4. Transcode to yuv420p.
7-5. Encode and write video frames.
- Finally, free memory.

But the encoding format is mpeg, which cannot be opened in the player included with windows, and the prompt is an unsupported format.


Although the vlc player can be opened and played normally, I need to play it normally on the player that comes with windows, because the output video will be played on the browser.


So I changed AV_CODEC_ID_MPEG4 to AV_CODEC_ID_H264, and the result is that although the file size of the output image is very large, only one picture is displayed during playback. I don't know what the problem is.


I was thinking about writing a new one, but I had no idea how to write a new one.
I would appreciate it if someone could write me an example.

ffmpeg concat skips frames near end of each subclip
3 janvier 2024, par calvinusesyourcodeSo I have some video files to concat but in the resulting video the last few frames of each subclip are buggy. Imagine in the last 5 frames the first 3 frames are skipped and so at the end of each clip it seems to jitter.


It should be virtually impossible for my input videos to have any differences between them, as they were all recorded on the same iPhone and all converted with the same command :


command = [
 'ffmpeg', '-y',
 '-i', input_path,
 '-vf', 'scale=1080:1920',
 '-r', '30',
 '-c:v', 'libx264',
 output_path
 ]
subprocess.run(command, check=True)


I have tried re-encoding instead of merely copying and adding
-r 30but that doesn't seem to work.

subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-c", "copy", output_path])


subprocess.run(["ffmpeg", "-y", "-f", "concat", "-safe", "0", "-i", temp_textfile, "-r", "30", "-c:v", "libx264", "-c:a", "aac", output_path], check=True)


Somewhere someone said to open in VLC and do a frame-by-frame, reporting that "the frames are actually there, just not visually when watching normally". In my case the frame-by-frame reveals the frames are indeed being skipped.

UPDATE : I am thinking that the way I am converting my files from .mov to .mp4 is the problem. Please suggest the best way to convert from iPhone 4k 60fps .mov files to nice 1080p 30fps .mp4 files. I know I could just use handbrake but I am trying to be a man here xD. Perhaps handbrake has a
View ffmpeg code for conversion.

UPDATE 2 : re-encoding the videos before concat with
-c:v libx264fixes the problem... which seems weird because that is how they were originally encoded...

def join_broll(video_paths, desired_length, clip_length=None, output_path="quick_clips.mp4", preserve_inputs=True):
 subclips = []
 total_duration = 0

 temp_textfile = os.path.join(run_folder, "broll_subclips.txt")
 j = 0
 with open(temp_textfile, "w") as file:
 while True:
 for i, video_path in enumerate(video_paths):

 time_left = desired_length - total_duration
 video_duration = duration_of(video_path)
 subclip_path = f"subclip_{i+j}.mp4"

 if (not clip_length and video_duration < time_left) or (clip_length and clip_length < time_left):

 if clip_length:

 subclips.append(subclip_path)
 subprocess.run(["ffmpeg", "-y", "-i", video_path, "-t", str(clip_length), "-c:v", "libx264", subclip_path]) # added "-c:v libx264"
 total_duration += clip_length
 file.write(f"file '{os.path.join('..', subclip_path)}'\n")

 else:
 
 subclips.append(subclip_path)
 subprocess.run(["ffmpeg", "-y", "-i", video_path, "-c:v", "libx264", subclip_path]) # added "-c:v libx264"
 total_duration += video_duration
 file.write(f"file '{subclip_path}'\n")

 total_duration += time_left
 file.write(f"file '{os.path.join('..', subclip_path)}'\n")

 break

 j += 1
 if desired_length - total_duration < 0.1:
 break
