Summary: vp8enc: getting trash if encoding from flv
Classification: Platform
Product: GStreamer
Version: git
OS/Version: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: gst-plugins-bad
AssignedTo: gstreamer-bugs at lists.freedesktop.org
ReportedBy: bug-track at fisher-privat.net
QAContact: gstreamer-bugs at lists.freedesktop.org
GNOME version: ---
if i use some flv to source to encode webm i get currupt, broken video. I
assume the reason is that some wrong packet is muxed at the beginning of
stream. If i use mkvinfo -v i get unusually small first video packet, since it
is a key frame it should be bigger. This packet probably deliver wrong init
values to decoder.
ways to reproduce:
create flv file (i use gst 0.10 to create flv file):
gst-launch -e videotestsrc num_buffers=100 ! ffenc_flv ! ffmux_flv ! filesink
location=test.flv
convert it (attention i encode it with gst 1.0):
gst-launch-1.0 filesrc location=test.flv ! decodebin ! vp8enc ! webmmux !
filesink location=test.webm
