Ich habe eine große Blu-Ray-Sammlung und möchte sie in meine iTunes-Mediathek aufnehmen, um sie auf AppleTV abzuspielen.
Ich muss die verschiedenen Audiostreams in ein geeignetes Format konvertieren.
Es gibt jedoch verschiedene Fehler-/Warnmeldungen, die ich bearbeiten muss.
Hier sind einige Beispiel-Codeausschnitte:

Erscheint nur, wenn ich versuche, die folgenden verlustbehafteten Formate zu konvertieren: ac3, dts und eac3. Mit verlustbehaftetem dts (als DTS-HD High Resolution) klappt es gut.
[out_0_0 @ 000000000046bc40] 100 buffers queued in out_0_0, something may be wrong.
Erscheint nur, wenn ich versuche, verlustfreies TrueHD zu konvertieren. Verlustfreies DTS-HD Master Audio ist problemlos möglich.

Diese Meldungen werden immer angezeigt, wenn ich versuche, alle Streams zu multiplexen.
Verschwinden sie, wenn ich Zeitstempel im pts-Format in den Container lege? Ich kann sie aus mkv extrahieren (mkvextract timecodes_v2 input.mkv 0:video.timecodes.txt 1:audio1.timecodes.txt 2:audio2.timecodes.txt 3:sub1.timecodes.txt 4:sub2.timecodes.txt 5:sub3.timecodes.txt 6:sub4.timecodes.txt), aber nur im timecodes_v2-Format. Kann ich timecodes_v2 in pts konvertieren und in den Container legen, um diese Meldungen zu vermeiden?
Beste grüße,
Felix

Ich habe es endlich gelöst.
Ich nehme den Video-Stream einfach direkt von einem Container in den anderen:
ffmpeg -i german_dd_to_alac__english_truehd_to_alac.mkv -map 0:0 -c copy german_dd_to_alac__english_truehd_to_alac.m4v
Und dann mache ich mein Ding:
ffmpeg^
-i german_dd_to_alac__english_truehd_to_alac.m4v -i audio1.m4a -i audio2.m4a -i sub1.srt^ -map 0:0 -map 1:0 -map 2:0 -map 3:0^
-metadata:s:a:0 language=ger -metadata:s:a:0 handler="Dolby Digital"^
-metadata:s:a:1 language=eng -metadata:s:a:1 handler="Dolby TrueHD"^
-metadata:s:s:0 language=ger -metadata:s:s:0 handler="Deutsch"^ -movflags disable_chpl^ -c:s mov_text -c:v copy -c:a alac^ final.m4v
Funktioniert einwandfrei. Keine Punkte- oder Zeitstempelfehler. Ich habe den Fehler „Frame-Größe nicht festgelegt“ gelöst, indem ich den Audio-Codec -c:a alac angegeben habe. Ich weiß nicht, warum, aber es funktioniert.
Der Fehler „100 Puffer in out_0_0 in Warteschlange gestellt, möglicherweise stimmt etwas nicht.“ ist immer noch vorhanden. Es wäre toll, wenn ich das auch lösen könnte.
EDIT: Sollte kein Problem sein:https://trac.ffmpeg.org/ticket/7703
