This is a temporary fix that may be remove once the deadlock is fixed.

GStreamer 1.22.2 is now available, this patch is no longer needed.

This reverts commit fc786049.

Use a tmp patched gst-libav to cope with decoding deadlock, fixes #37551

infinite locking loop resolution fixes #33514

See merge request devtools/qr-lipsync!12

Paul GOULPIE authored 4 years ago and Florent Thiery committed 4 years ago

reproducible with a corrupted source file and the following command:
gst-launch-1.0 filesrc location="corrupted-file.mp4" ! decodebin name=dec \
 dec. ! fakesink \
 dec. ! fakesink

observation: deferred link resolution fails and gstreamer does not
transmit an error message => the main loop is never left => the program
remains blocked.

resolution: interception of the warning message: deferred link resolution
failure and triggering of the end of stream process.

remove sys.exit call fixes #33513

See merge request devtools/qr-lipsync!11

detect: Management of uri flows, refs #33406

See merge request devtools/qr-lipsync!10

Use of uridecodebin instead of filesrc.
Allowing the analysis of remote flows via the http protocol.
Remains compatible with the previous functional.

detect: Handle missing video frame duration meta

See merge request !9

This way stream from openh264 where gstreamer doesn't set duration on
all buffers are properly detected
