  • Handling multiple line subtitles of Right aligned languages(arabic) in Moviepy

    24 décembre 2023, par Stanger Danger

    I am trying to add Arabic subtitles on a video using Moviepy. The issue I'm facing is related to alignment of Arabic text, as it progresses from right to left, instead of left to right in English language.

    


    enter image description here

    


    As text length gets more and more, Moviepy trims the words from both ends, this issue can be resolved if we break the text into multiple lines. This works well for English language but for Arabic, the first line becomes the last line because of the (Right-Left)alignment.

    


    enter image description here

    


    The text on Second line should come first on the first line at the start, while end chuck of first text towards the left corner should render on the second line, but it is getting rendered as English language, Left to right alignment.

    


    Here is my code :

    


    def add_subtitles(address_subtitles, address_video):
  video = VideoFileClip(address_video)
  generator = lambda txt: TextClip(txt, font='Arial', fontsize=22, color='black', stroke_width=2, method='caption', align='south', size=video.size)
  subtitles = SubtitlesClip(address_subtitles, generator)
  #print()

  result = CompositeVideoClip([video, subtitles.set_pos(('center','bottom'))])
  result.write_videofile("arabic_with_hardcoded_subtitles_3.mp4", fps=video.fps, temp_audiofile="temp-audio.m4a", remove_temp=True, codec="libx264"
  , audio_codec="aac")


    


  • FFMPEG : Add additional audio track to video file

    29 décembre 2016, par Lukas

    I have two video file with the following streams :

    File 1 :

    Stream #0:0(deu) : Audio : aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 126 kb/s (default)
Stream #0:1(deu) : Audio : ac3 (ac-3 / 0x332D6361), 48000 Hz, 5.1(side), fltp, 384 kb/s
Stream #0:2(eng) : Video : h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 4971 kb/s, 23.98 fps, 23.98 tbr, 2997 tbn, 5994 tbc (default)
Stream #0:3 : Video : mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 480x480 [SAR 72:72 DAR 1:1], 90k tbr, 90k tbn, 90k tbc

    File 2 :

    Stream #0:0(eng) : Audio : aac (LC) (mp4a / 0x6134706D), 48000 Hz, stereo, fltp, 126 kb/s (default)
Stream #0:1(eng) : Audio : ac3 (ac-3 / 0x332D6361), 48000 Hz, 5.1(side), fltp, 384 kb/s
Stream #0:2(eng) : Video : h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 4925 kb/s, 23.98 fps, 23.98 tbr, 23976 tbn, 47952 tbc (default)
Stream #0:3(eng) : Subtitle : eia_608 (c608 / 0x38303663), 1920x1080, 0 kb/s
Stream #0:4 : Video : mjpeg, yuvj420p(pc, bt470bg/unknown/unknown), 480x480 [SAR 72:72 DAR 1:1], 90k tbr, 90k tbn, 90k tbc

    Both files have exactly the same video content , but the first video has a german audio track and the second one an english audio track.

    How can I extract the audio track from the german video file and add it to the english one, without losing the english subtitles and being able to choose between these audio tracks in a media player ?

    I searched about this and I found multiple answers to similar questions, but none of them worked : Some included only one audio track and some played both of them at the same time.

    I’m not sure if this question should be asked on Super User, but as there are alrealy many questions about ffmpeg on Stack Overflow, I asked it here.
