Summary: [flvdemux] Internal flow error when demuxing speex
Classification: Platform
Product: GStreamer
Version: git
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-good
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: shreddingwork at gmail.com
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
Currently speexdec expects streamheader and vorbiscomment to be present in
caps: vital speex header is extracted/generated from the former. In case these
2 are absent in caps, first 2 packets are treated as these two.
In FLV format speex data is always present in Mono, Wideband as stated here:
http://download.macromedia.com/f4v/video_file_format_spec_v10_1.pdf (document
page 71).
So, there is no speex header present in FLV and flvdemux generates none.
This situation leads to speexdec trying to generate header from the first
packet using speex_packet_to_header libspeex routine, which fails, and message
"This doesn't look like a Speex file" is printed out.
