Double rtspsrc, single mkv containter; plus multifilesrc and multifilesink

kim
Hullo all,

The task: record from two IP cameras via rtsp, and save them into a
continuous stream of files, each lasting 5 minuets, and having each file
containing two video streams; two different angles of the same area.
Then I need another pipeline to 'glue' together any interval of
recordings, still keeping the two streams in one container file.

The two feeds needs to be timed within as few frames as possible of each
other, and there has to be no frame loss between the files, so as to not
have any drop in quality in the finished product. For this reason,
multifilesink/src seemed like the best option, as the splitmuxsink
element has some frame-drop issues.

The pipeline for the first task is:

gst-launch-1.0 -ev \
        mpegtsmux name=mux \
        ! multifilesink next-file=max-duration max-file-duration=300000000000
post-messages=true location=/path/%05d.ts \
        rtspsrc location=IP.CAMERAS.ADDRESS.1 'ntp-sync=true
protocols=GST_RTSP_LOWER_TRANS_TCP ntp-time-source=1' \
        ! queue ! capsfilter caps='application/x-rtp,media=video' \
        ! rtph264depay ! mux. \
        rtspsrc location=IP.CAMERAS.ADDRESS.2 'ntp-sync=true
protocols=GST_RTSP_LOWER_TRANS_TCP ntp-time-source=1' \
        ! queue ! capsfilter caps='application/x-rtp,media=video' \
        ! rtph264depay ! mux.

Which works(though maybe not, given later problems, more on that in a
bit..).

The second pipeline:

gst-launch-1.0 -ev \
        matroskamux name=mux \
        ! filesink location=/path/to/onefile.mkv \
        multifilesrc location=/path/"%05d.ts" \
        ! decodebin name=bin \
        bin.src_0 ! x264enc ! h264parse ! mux. \
        bin.src_1 ! x264enc ! h264parse ! mux.

Which works - sometimes. Sometimes, it stitches the clips together fine,
and it looks like the streams are synchronous, without any frame-loss.
Other times, it simply stalls out, the output looks frozen, and the file
doesn't grow beyond a certain size. The produced file will then have
maybe one or two seconds of video in it - no matter how long I leave it
for.

The output it stalls out at is:

 >^Chandling interrupt.
Interrupt: Stopping pipeline ...

Now, I can run the second pipeline as many times on the same recordings
as I'd like, and the outcome will be the same. Alternately, on some
recordings - everything goes fine, and the second pipeline runs smoothly
through. Due to this, I think the problem is in the first pipeline, and
in how the recordings are made in the first place..?

I know if I try to shove the rtspsrc recordings directly into a simple
filesink to .mkv file, that time timestamp is wrong, and maybe this has
something to do with my issue?

I've tried doing some experimentation, and if I substitute the rtspsrc
with some two videotestsrc, it's never a problem to stitch the files
together. Like so:

gst-launch-1.0 -ev \
     mpegtsmux name=mux \
     ! multifilesink next-file=max-duration
max-file-duration=300000000000 post-messages=true location=/path/%05d.ts
\
     videotestsrc ! "video/x-raw, width=(int)1280, height=(int)720,
format=(string)I420" \
     ! x264enc ! mux. \
     videotestsrc pattern=11 ! "video/x-raw, width=(int)1280,
height=(int)720, format=(string)I420" \
     ! x264enc! mux.

Further making me believe that the issue is with the rtspsrc, or
something, however, I've really run out of ideas.

Any suggestions or insights are welcome, and I hope I've made myself
clear.

Regards, Kim
