You can't convert MP3 to AAC or the other way around without reencoding. The formats are too different. > I wonder if gstreamer can do smth like ffmpeg is capable of - ffmpeg > -i 1.ts -c copy -bsf:a aac_adtstoasc -y output.mp4 That ffmpeg command is not converting MP3 to AAC without reencoding. What it does is to convert MPEG2/4 ADTS AAC to raw MPEG4 AAC with the configuration box required by MP4. In GStreamer, the aacparse element would do that. -- Sebastian Dröge, Centricular Ltd · http://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Also what's the input file you're using, can you share (part of) it? -- Sebastian Dröge, Centricular Ltd · http://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

Either tsdemux is not actually linked to aacparse here, or the linking to mp4mux does not work. -- Sebastian Dröge, Centricular Ltd · http://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |

That's a missing feature. Can you file a bug about that here? https://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer Thanks! -- Sebastian Dröge, Centricular Ltd · http://www.centricular.com _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
