How to embed subtitles into an mp4 file using gstreamer

27 août 2021, par Stephen

My Goal

I'm trying to embed subtitles into an mp4 file using the mp4mux gstreamer element.

What I've tried

The pipeline I would like to use is :

GST_DEBUG=3 gst-launch-1.0 filesrc location=sample-nosub-avc.mp4 ! qtdemux ! queue ! video/x-h264 ! mp4mux name=mux reserved-moov-update-period=1000 ! filesink location=output.mp4 filesrc location=english.srt ! subparse ! queue ! text/x-raw,format=utf8 ! mux.subtitle_0&#xA;

It just demuxes a sample mp4 file for the h.264 stream and then muxes it together with an srt subtitle file.

The error I get is :

Setting pipeline to PAUSED ...&#xA;0:00:00.009958915 1324869 0x5624a8c7a0a0 WARN                 basesrc gstbasesrc.c:3600:gst_base_src_start_complete:<filesrc0> pad not activated yet&#xA;Pipeline is PREROLLING ...&#xA;0:00:00.010128080 1324869 0x5624a8c53de0 WARN                 basesrc gstbasesrc.c:3072:gst_base_src_loop:<filesrc1> error: Internal data stream error.&#xA;0:00:00.010129102 1324869 0x5624a8c53e40 WARN                 qtdemux qtdemux_types.c:239:qtdemux_type_get: unknown QuickTime node type pasp&#xA;0:00:00.010140810 1324869 0x5624a8c53de0 WARN                 basesrc gstbasesrc.c:3072:gst_base_src_loop:<filesrc1> error: streaming stopped, reason not-negotiated (-4)&#xA;0:00:00.010172990 1324869 0x5624a8c53e40 WARN                 qtdemux qtdemux.c:3237:qtdemux_parse_trex:<qtdemux0> failed to find fragment defaults for stream 1&#xA;ERROR: from element /GstPipeline:pipeline0/GstFileSrc:filesrc1: Internal data stream error.&#xA;Additional debug info:&#xA;gstbasesrc.c(3072): gst_base_src_loop (): /GstPipeline:pipeline0/GstFileSrc:filesrc1:&#xA;streaming stopped, reason not-negotiated (-4)&#xA;ERROR: pipeline doesn&#x27;t want to preroll.&#xA;Setting pipeline to NULL ...&#xA;Freeing pipeline ...&#xA;</qtdemux0></filesrc1></filesrc1></filesrc0>

My Thoughts

I believe the issue is not related to the above warning but rather mp4mux's incompatibility with srt subtitles.

The reason I belive this is because, other debug logs hint at it, but also stealing the subititles from another mp4 file and muxing it back together does work.

gst-launch-1.0  filesrc location=sample-nosub-avc.mp4 ! qtdemux ! mp4mux name=mux ! filesink location=output.mp4 filesrc location=sample-with-subs.mp4 ! qtdemux name=demux demux.subtitle_1 ! text/x-raw,format=utf8 ! queue ! mux.subtitle_0&#xA;

A major catch 22 I am having is that mp4 files don't typically support srt subtitles, but gstreamer's subparse element doesn't support parsing mp4 subtitle formats (tx3g, ttxt, etc.) so I'm not sure how I'm meant to put it all together.

I'm very sorry for the lengthy question but I've tried many things so it was difficult to condense it. Any hints or help is appreciated. Thank you.

How to encode multi audio streams with different options at the same time using ffmpeg

20 mars 2012, par Luca Borrione

I'm trying to encode a dvd using ffmpeg.

$ffmpeg -i VTS_01_1.VOB

Input #0, mpeg, from &#39;VTS_01_1.VOB&#39;:

Duration: 00:38:06.52, start: 0.287267, bitrate: 3756 kb/s

Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p, 720x576 [SAR 64:45 DAR 16:9], 9800 kb/s, 25 fps, 25 tbr, 90k tbn, 50 tbc

Stream #0:1[0x80]: Audio: ac3, 48000 Hz, 5.1(side), s16, 384 kb/s

Stream #0:2[0x81]: Audio: ac3, 48000 Hz, 5.1(side), s16, 384 kb/s

Stream #0:3[0x82]: Audio: ac3, 48000 Hz, 5.1(side), s16, 384 kb/s

Stream #0:4[0x83]: Audio: ac3, 48000 Hz, mono, s16, 96 kb/s

Stream #0:5[0x28]: Subtitle: dvd_subtitle

Stream #0:6[0x29]: Subtitle: dvd_subtitle

Stream #0:7[0x23]: Subtitle: dvd_subtitle

Stream #0:8[0x24]: Subtitle: dvd_subtitle

Stream #0:9[0x26]: Subtitle: dvd_subtitle

Stream #0:10[0x27]: Subtitle: dvd_subtitle

From the above streams I'm interested in keeping two audio streams : number 1 and 4.
As you can see the number 4 is already 96kbps so I tried to execute a command which could treat the two streams in a different way :

cat VTS_01_1.VOB | nice ffmpeg -i - -s 640x368 -vcodec libtheora -r 25 -b:v 1200k -an -metadata title="My Title" -pass 1 -passlogfile "/media/data/outputlog" -f ogg -y /dev/null



cat VTS_01_1.VOB | nice ffmpeg -i - -map 0:0 -s 640x368 -vcodec libtheora -r 25 -b:v 1200k -async 1 -metadata title="My Title" -map 0:1 -acodec libvorbis -ac 6 -ar 48000 -b:a 192k -metadata title="english" -map 0:4 -acodec libvorbis -ac 2 -ar 48000 -b:a 96k -metadata title="commented" -pass 2 -passlogfile "/media/data/outputlog" "/media/data/output.ogv"

What I would like to obtain is :

Input #0, ogg, from &#39;output.ogv&#39;:

Duration: 00:38:07.20, start: 0.000000, bitrate: 1360 kb/s

Stream #0:0: Video: theora, yuv420p, 640x368 [SAR 46:45 DAR 16:9], 25 fps, 25 tbr, 25 tbn, 25 tbc

Stream #0:1: Audio: vorbis, 48000 Hz, stereo, s16, 192 kb/s

Stream #0:2: Audio: vorbis, 48000 Hz, stereo, s16, 96 kb/s

Instead with the above command I obtain :

Input #0, ogg, from &#39;output.ogv&#39;:

Duration: 00:38:07.20, start: 0.000000, bitrate: 1360 kb/s

Stream #0:0: Video: theora, yuv420p, 640x368 [SAR 46:45 DAR 16:9], 25 fps, 25 tbr, 25 tbn, 25 tbc

Stream #0:1: Audio: vorbis, 48000 Hz, stereo, s16, 96 kb/s

Stream #0:2: Audio: vorbis, 48000 Hz, stereo, s16, 96 kb/s

So how can I specify different params for multiple audio streams ?

BTW : I'm on lubuntu oneiric with the latest ffmpeg from git

android ffmpeg error fatal signal 11

10 décembre 2014, par AKUMA

I’m using ffmpeg on Android. and Use RTSP webcam.

I refer here.

I get good video.

But I receive error when I ended the video.

Fatal signal 11 (SIGSEGV) at 0x8a7c0d04 (code=1), thread 2537 (Thread-13225)

So I found the error using the log. But I don’t know why the error occurred.

The code below is the location of the error.

void closeMovie(){

  av_read_pause(gFormatCtx);

  if (gVideoBuffer != NULL) {

    free(gVideoBuffer);

    gVideoBuffer = NULL;

  }

  if (gFrame != NULL)

      av_free(gFrame);

  if (gFrameRGB != NULL)

      av_free(gFrameRGB);

  if (gVideoCodecCtx != NULL) {

      avcodec_close(gVideoCodecCtx);

      av_free(gVideoCodecCtx);

      gVideoCodecCtx = NULL;

  }

  if (gFormatCtx != NULL) {

      **av_close_input_file(gFormatCtx);** //here

      gFormatCtx = NULL;

  }

}

and

void av_close_input_file(AVFormatContext *s)

{

  AVIOContext *pb = (s->iformat->flags &amp; AVFMT_NOFILE) || (s->flags &amp; AVFMT_FLAG_CUSTOM_IO) ?

                   NULL : s->pb;

  **av_close_input_stream(s);**// here

  if (pb)

    avio_close(pb);

}

and

void av_close_input_stream(AVFormatContext *s)

{

    flush_packet_queue(s);

    if (s->iformat->read_close)

       **s->iformat->read_close(s);** //here

    avformat_free_context(s);

}

if //s->iformat->read_close(s); not crash

But I can not open the video once more. Again to open the video I have to quit the app.

Sorry, I can’t speak English very well.
Thanks for reading.
