私はPythonでRPIを使ってタイムラプスをやっています。
画像を撮影してフォルダーに保存する場合: 問題はありません。ただし、FFMPEG でビデオを作成するには問題があります。
X 枚の画像の後、スクリプトはビデオの作成を開始します。最初のフレームのみのビデオが作成され、フォルダー内のすべての画像が最初のフレームで上書きされます (?!)。エラー メッセージは表示されません。
それで、私は何を間違っているのでしょうか?

これを試してみましたが、すべて正常です:https://lindevs.com/install-ffmpeg-on-raspberry-pi/
答え1
簡単な解決策: 入力ファイル名を一重引用符 ( ffmpeg … -i '…/*.jpg' …) で囲みます。
より詳しい説明: 問題は、*ffmpeg がファイル名を認識する前に、シェルによってファイル名のリストに展開されることです。
つまり、元のコマンドは間違っています:
ffmpeg -f image2 -framerate 1 -pattern_type glob -start_number %d \
-i /media/julien/USBKEY/capture_%d/%d/*.jpg \
-r 5 -c:v libx264 -pix_fmt yuv420p \
/media/julien/USBKEY/capture_%s/%d/out%d.mp4 -y
ffmpeg は基本的に画像のリストとともに呼び出されます。
-i image1.jpg image2.jpg …
ffmpeg の場合、2 番目の画像ファイルは出力ファイル名として解釈されます。 を渡したので-y、ffmpeg はこの画像を上書きします。(グローバル オプションは引数リストの先頭に指定する必要があることに注意してください-y。)
あなたがすべきことはワイルドカードを引用するこうすることで、シェルはそれを解釈せず、ffmpeg に渡すので、ffmpeg は内部的にワイルドカードをフォルダー内の画像のリストに展開します。
ffmpeg -f image2 -framerate 1 -pattern_type glob -start_number %d \
-i '/media/julien/USBKEY/capture_%d/%d/*.jpg' \
-r 5 -c:v libx264 -pix_fmt yuv420p \
/media/julien/USBKEY/capture_%s/%d/out%d.mp4 -y
例も参照ここ。
プログラム コードでは、subprocess直接呼び出すのではなく、Python フォーマット文字列を使用してモジュールを活用することをお勧めしますsystem。
import subprocess
subprocess.check_output(
f"ffmpeg -y -f image2 -framerate 1 -pattern_type glob -start_number {nom_premiere_image} -i '/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/*.jpg' -r 5 -c:v libx264 -pix_fmt yuv420p /media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/out{nom_sous_dossier}.mp4", shell=True
)
さらに良い方法は、コマンド内のすべてをリストに入れて渡すことです。
subprocess.check_output([
"ffmpeg", "-y", "-f", "image2", "-framerate", "1", "-pattern_type", "glob", "-start_number", nom_premiere_image,
"-i", f"'/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/*.jpg'",
"-r", "5", "-c:v", "libx264", "-pix_fmt", "yuv420p",
f"/media/julien/USBKEY/capture_{nom_dossier}/{nom_sous_dossier}/out{nom_sous_dossier}.mp4",
])
