Description Xu Han 2014-02-26 05:57:23 UTC

Description of problem:
qemu-kvm flood with 'Spice-Warning **: mjpeg_encoder.c:799:mjpeg_encoder_start_frame: unsupported format 2'

Version-Release number of selected component (if applicable):
spice-server-0.12.4-5.el7.x86_64
spice-glib-0.20-8.el7.x86_64
spice-gtk3-0.20-8.el7.x86_64
qemu-kvm-rhev-1.5.3-49.el7.x86_64

How reproducible:
100%

Steps to Reproduce:
1. let spice monitor flushs frequently under text mode.
1.1. login text mode
# init 3
1.2. touch files on guest
# for ((i=0;i<5000;i++)); do touch `printf "%032d" $i`; done
1.3. list files name
# ls

Actual results:
qemu-kvm flood with:
(/usr/libexec/qemu-kvm:19159): Spice-Warning **: mjpeg_encoder.c:799:mjpeg_encoder_start_frame: unsupported format 2
(/usr/libexec/qemu-kvm:19159): Spice-Warning **: mjpeg_encoder.c:799:mjpeg_encoder_start_frame: unsupported format 2

(/usr/libexec/qemu-kvm:19159): Spice-Warning **: mjpeg_encoder.c:799:mjpeg_encoder_start_frame: unsupported format 2
...

Expected results:
should not generate so many messages.

Comment 2 Christophe Fergeau 2014-02-26 15:03:42 UTC

This probably does not deserve a spice_warning(), sent a patch to downgrade that log to spice_debug() which is not shown in logs by default
