Hi all - latest defector from ffmpeg here, and already the whole kit
seems to be a lot cleaner and smoother to to run.
However, I have new problems (or old ones that didn't appear through
cruft). I have been on the irc while I waited to get on to the list,
and this has been the notes so far:
I started with the latest release 0.7.2. I was using -map_metadata to
pick the individual programs out of a mpegts stream, and that worked
while writing to file, but wouldn't work for an avserver/ffserver
feed. I'd only get audio (already one better than ffmpeg- it errored
and wouldn't do a thing there).
So I went looking for help on irc and I was told that I could use -map
0:p:pid instead. That refused to work sending to ffserver as well, but
it did work to file. The stream mapping actually looked screwed up:
0.1 -> 0.0, etc.
I was then advised to use the latest in the git repo as that last
command wouldn't work except on avconv exclusively. So I picked up
v0.7-2134-g12dca02 from git and built, and I got accurate stream
mapping but a seg fault:
Stream mapping:
Stream #0:0 -> #0:0Segmentation fault (core dumped)
This happens in both splitting the stream and sending it whole to
avserver as ffm.
So the guru on the list had a look at this, and found in the code that
when sending a feed to avserver, avconv actually gets the stream
mapping from avserver.
In the next day I have tried using truss and gdb to get more
information to help.
truss output: http://pastebin.com/h0j2pva6
gdb wouldn't work with all the options for me (but I'm not very good
with it)
Further testing confirmed no other problems:
mkv (x264/vorbis) transcoded to flv no problems.
Copying directly to ts had no problems.
Feeding to avserver with feed set as ts (in the server and on the
avconv options) showed perfect mapping, avserver didn't barf, but
ended in broken pipe (ffserver did say incompatible file type, though;
so it might be a bug).
Tried copying to ffm with sending to avserver and got a new error:
Data stream encoding not supported yet (only streamcopy).
I then tried cloning a new git head and build, and still got the same
error. At this point I received a patch from elenril which I patched
0.7-2134 with and rebuilt: still got a seg fault.
So that is the results of my investigations so far, and I'm still
hunting.
Any ideas on what I should try now?

Ok. Despite recent diversions of this thread, here is the latest update:
git head clone (avconv version v0.7-2192-g5695ae4): Yay! No seg fault.
$ ./avconv -debug 9 -f mpegts -i testpipe -vsync 0 -vcodec copy -acodec
copy -map 0:p:1601 http://127.0.0.1:8090/stream1.ffm -vsync 0 -vcodec
copy -acodec copy -map 0:p:1605 http://127.0.0.1:8090/stream2.ffm -vsync
0 -vcodec copy -acodec copy -map 0:p:1608 http://127.0.0.1:8090/stream3.ffm
Output:
Data stream encoding not supported yet (only streamcopy).
Adding a "-map -0:3" to remove the data stream didn't help this.
$ ./avconv -debug 99 -f mpegts -i testpipe -vsync 0 -vcodec copy -acodec
copy -map 0:0 -map 0:1 http://127.0.0.1:8090/stream1.ffm -vsync 0

-map 0:8 -map 0:9 http://127.0.0.1:8090/stream3.ffm
Output:
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:1 -> #0:1 (copy)
Stream #0:6 -> #1:0 (copy)
Stream #0:7 -> #1:1 (copy)
Stream #0:8 -> #2:0 (copy)
Stream #0:9 -> #2:1 (copy)
Press ctrl-c to stop encoding
Broken pipe
As you can see the new code is a beautiful thing- the stream mapping is
perfect.
Trying a single feed:
$ ./avconv -debug 9 -f mpegts -i testpipe -vsync 0 -vcodec copy -acodec
copy -map 0:v -map 0:a http://127.0.0.1:8090/stream1.ffm
or mapping the streams individually as far as I could tell- got painful
trying to match the right streams like moving targets. The output:
Stream mapping:
Stream #0:0 -> #0:0 (copy)
Stream #0:6 -> #0:1 (copy)
Stream #0:8 -> #0:2 (copy)
Stream #0:1 -> #0:3 (copy)
Stream #0:7 -> #0:4 (copy)
Stream #0:9 -> #0:5 (copy)

Its a beautiful thing to see- thanks guys. Now we can see the problem
with avserver. I'm 100% sure where to start looking but I'll see if I
can spot something, and if someone can provide some pointers it'd be
appreciated.
I have a question or two regarding avserver/ffserver:
Has it ever worked as expected? In the docs and man pages it says
streaming from file has never worked, and yet that has worked for me.
I've never got the live feed happening though...
Cheers
