    avutil/fifo : delay addition of const from 78d3453c4a2efef9bc079e8f3458653beafcf990 until next major ABI bump

    This unbreaks API, for example audacity has more build errors due to this

  • ffmpeg to embed subtitles [closed]

    29 octobre 2023, par zanoth

    Intend to collect some stuff for academical purpose, to introduce in a seminary.&#xA;Attempting to embed subtitles in the frames of a mp4 file, below some commands that i've been tried out :

    &#xA;

    ffmpeg -i input.mp4 -vf subtitles=subt.srt output.mp4 &#xA;&#xA;ffmpeg -i VID_20230918_161450.mp4  -f srt -i subtitles1.srt -map 0:0 -map 0:1 -c:v copy -c:a copy -c:s mov_text output.mp4&#xA;&#xA;ffmpeg -i seu_video.mp4 -vf "subtitles=seu_arquivo.srt" -c:v libx264 -c:a aac -strict experimental -b:a 192k -y seu_video_com_legendas.mp4&#xA;

    &#xA;

    ...according to the major issues/responses/or "oracles" around the web.

    &#xA;

    With the first one, i got as response :

    &#xA;

    &#xA;

    [AVFilterGraph @ 0x557e87157240] No such filter : 'subtitles1.srt' < br/> > Error reinitializing filters !

    &#xA;

    &#xA;

    The second creates the output.mp4 but it comes without subtitles.

    &#xA;

    The third, surprisingly, was well succed, for a moment. I will explain :&#xA;as i'd to translate the video, I wanted to conduct some tests... At the first, the mp4 had a little more than few seconds, which was well succed. Calling the purposed video, it brokes :

    &#xA;

    &#xA;

    [Parsed_subtitles_0 @ 0x558e29010280] Unable to open subtitles1.srt

    &#xA;

    &#xA;

    ...subtitles.srt which is exatcly the same file tried firstly.

    &#xA;

    "Phantonessly", both of they, the test and the purposed video ones, doens't work anymore.

    &#xA;

    I made up some changes here and there, but for summarize is it.&#xA;The SRT file have none syntax erros, as you can see :

    &#xA;

    &#xA;

    1
    &#xA;0:0:0.000 —> 0:3:0.000
    &#xA;test, teste, teste, á ?

    &#xA;

    &#xA;

    It's for academical purposes.

    &#xA;

    Thanks.
