私はPythonスクリプトの中から以下のコマンドを実行しようとしています。ffmpegコマンドはコマンドラインから動作しますが、pythonサブプロセスからは動作しません.Popen
ffmpeg -y -loglevel verbose -i /var/www/Intro30.mp4 -i /var/www/temp/videoHD.mp4 -i /var/www/Credits30.mp4 -filter_complex '[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1 [v] [a]' -map '[v]' -map '[a]' /var/www/temp/merged.mp4
ただし、ファイルが壊れています。これが出力です。

一部の行が削除され、行の制限を超えません。
私がffmpeg行を実行するために使用するpythonメソッドです。
def ffmpeg(args):
err = None
command = [
ffmpegcmd, '-y',
'-loglevel', loglevel
] + args
ffmpeg = subprocess.Popen(command, stderr=subprocess.PIPE ,stdout=subprocess.PIPE, universal_newlines=True)
while err == None:

time.sleep(1)
if err:
print(" ".join(command))

*編集
私は、引数、すなわち周りの単一引用符が必要なコマンドを使用する必要があり、これまで'[0:0] [0:1] [1:0] [1:1] [2:0] [2:1] concat=n=3:v=1:a=1 [v] [a]'上記の機能は動作しません。だから私は文字列としてコマンドを扱うケースのための別の関数を作った。ここがあります。
def ffmpegStr(args):
err = None
command = [
ffmpegcmd, '-y',
'-loglevel', loglevel
] + args
commandStr = " ".join(command)
print(commandStr)
ffmpeg = subprocess.Popen(shlex.split(commandStr), stderr=subprocess.PIPE ,stdout=subprocess.PIPE, universal_newlines=True)
while err == None:
out, err = ffmpeg.communicate()
time.sleep(1)
if err:
print(commandStr)
raise Exception(err)
ご覧のとおり、サブプロセスに何が渡されているかを確認するためにプリントを追加しました.Popen機能。これは、ffmpegコマンドが期待どおりに実行されない場合に使用される方法です。
変数としてffmpegcmdを使用するので、必要に応じて両方の関数で1つの変更を加えてffmpegのバージョンを変更できます。
argsは、私がffmpegにしたいものに固有の引数のリストです。
また、両方の関数のログレベルを1行で変更するオプションがあるので、変数を使用してください。
