  • FFMPEG : merge mkv + audio + subtitles [closed]

    24 décembre 2022, par vespino

    I have a 4K video with Japanese audio and a 1080p video with English audio. I have extracted the audio from the English video file and would like to know how to merge the following files :

    


    jap_video.mkv
eng_audio.acc
nld_subtitles.srt


    


    I don't mind the original audio and subtitles overwritten, I would like to end up with just 1 file containing my audio and my subtitles.

    


    This is how I merge jap_video.mkv + eng_audio.acc

    


    ffmpeg -i jap_video.mkv -i eng_audio.acc -c:v copy -map 0:v:0 -map 1:a:0 output.mkv


    


    Following this I merge output.mkv + nld_subtitles.srt

    


    ffmpeg -i output.mkv -f srt -i nld_subtitles.srt -map 0:0 -map 0:1 -map 1:0 -c:v copy -c:a copy -c:s srt -metadata:s:s:0 language=nld output_srt.mkv


    


    This works fine, but is it possible in one command ? A nice to have would be to name both audio and subtitles as I'm doing with the second command.

    


  • 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")

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)

    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

    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.
