'Invalid argument' or 'Assertion ost->source_index >= 0 failed at ffmpeg.c:2932' message on subtitle metadata

Description

Summary of the bug:

Trying to copy streams plus a TTF font file to support hardware players that need an embedded font for subtitles.

  • 1 video stream from MtStHel?.mkv (This file only contains 1 video stream and was previously created with ffmpeg)
  • 3 audio streams from MtStHel?-eng-1-normalized.mp2, MtStHel?-ger-2-normalized.mp2 and MtStHel?-eng-3-normalized.mp2 (Each file only contains * 1 audio track and was also previously created with ffmpeg)
  • 2 subtitle streams from MtStHel?-en-subtitles.sub and MtStHel?-de-subtitles.sub (Each file created with the 'mencoder -vobsubout ...' command)
  • 1 attachment: a TrueType? font file 'tahoma.ttf', 383804 bytes, tagged as 'mimetype=application/x-truetype-font' as described in 'http://ffmpeg.org/ffmpeg.html'.

ffmpeg quits with an "Attachment stream 6 has no mimetype tag" and finally an "Invalid argument" message.

No output is produced.

Changing the mimetype to "application/octet-stream" or "application/x-font-ttf gives the same result.

Omitting the attachment gives a correct result, until it comes to the hardware player mentioned:
That player lists the 2 subtitle streams, but can not display them (no text on the screen).

Hardware: MSI Movie Station HD1000

When I use '-metadata:s:t:0' instead of '-metadata:s:0' to specify that only the attachment is to be tagged, then ffmpeg issues a different error:

Change History

comment:1 Changed 5 months ago by cehoyos

  • Keywords mkv metadata added; ffmpeg, metadata, mimetype, subtitles removed
  • Component changed from FFmpeg to undetermined

Is this also reproducible with current git head?

comment:2 Changed 5 months ago by cehoyos

  • Status changed from new to open
  • Reproduced by developer set
  • Component changed from undetermined to FFmpeg
  • Priority changed from minor to important
  • Version changed from unspecified to git-master
  • Keywords crash abort regression added; mkv metadata removed

Regression since 1cadab6 (crash in select_input_file() in ffmpeg.c) / 429c6ca (assert).

comment:3 Changed 5 months ago by Cigaes

Should be fixed by adding this:

ost->finished = 1;

In the "handle attached files" loop in ffmpeg_opt.c, along with all ost init.
No time to make a proper patch right now, sorry.

comment:4 Changed 5 months ago by Cigaes

Should be fixed in Git head.
rtmi1: do you confirm?

comment:5 Changed 5 months ago by cehoyos

  • Status changed from open to closed
  • Resolution set to fixed

Fixed by Nicolas George.
