Status about streaming out FLV format

[alrama]

Someone can give some news about the status of streaming out flv format (wiki article) ? On my side I made these tests:

1. On WinXP, used one of latest nightly build with: vlc.exe udp://@<multicast input> :sout=#transcode{vcodec=FLV1,acodec=mp3,sameplerate=44100}:std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:1234/stream.flv} . VLC starts and crash immediately .
2. On WinXP, rebuilded it by SVN source. Compiled the source using Win32 Contrib package upgraded with a new libavformat.a and libavcodec.a from ffmpeg source. Source ffmpeg was compiled with a mp3lame new build. Same result of previous attempt.
3. Because maybe other O.S. behave different , I gave a try with a nightly on a Debian virtual machine. I got no better luck

But . someone said they did it .
Some words from these smart guys ?

[Jean-Baptiste Kempf]

Just a quick question; do you have mp3lame built in ?
have you tried to just mux=flv?
Log paste ?

[alrama]

thank you for quick reply !

1. Yes. My ffmpeg configure command: ./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --extra-cflags=-I/usr/local/include --cc="gcc -mno-cygwin" --enable-libmp3lame --enable-pp --enable-gpl --prefix=/usr/local --extra-ldflags=-L/usr/local/lib
2. With mux=flv VLC doesn't crash but the stream doesn't start and messages (messages level = 0) show:

main error: Reloading playlist not implemented.
main info: creating httpd
main error: no sout mux module matched "flv"
stream_out_standard error: no suitable sout mux module for `http{mime=video/x-flv}/flv://0.0.0.0:1234/stream.flv'
stream_out_transcode error: cannot create chain
main error: stream chain failed for `transcode{vcodec=FLV1,acodec=mp3,sameplerate=44100}:std{access=http{mime=video/x-flv},mux=flv,dst=0.0.0.0:1234/stream.flv}'
main error: cannot start stream output instance, aborting

3. These are messages recorded (log level=2) until crash:

[collintmiller]

Ah, I've had similar questions. But this thread seems to have better seed information.

I hope this can get figured out.

[thommyboy]

Any new informationen on VLC streaming out FLV?
I would really appriciate this feature as I need to
"simulate" (offline) a LiveStream in a Flash-
presentation...

Any other ways to do this- like having a (simple)
streaming server installed locally?

How to Stream flv with VLC player from TVU Player!!

This is a guide how to stream flv from local computer only.
I've only tested in local computer so if anyone have tried to connect with two computers or other devices like computer (server) and console (client).
Please send a PM to me and describe how you did it.

[Programs you need]

* TVU Player latest version

* VLC Player version 0.8.6a

* VLC Player version 0.9.0-svn

* FLV Player 1.3.3


[Guide]

To get sound in your flv streaming you need to have two VLC Player installed.


Stage #1) Start-up TVU Player and choice a channel you want to see.

Stage #2) Start-up VLC Player 0.8.6a and go to File -> Open networkstream

Stage #3) Choose (( HTTP/HTTPS/FTP/MMS )) then in the URL field type:
127.0.0.1:8901 because it’s the IP address for TVU Player is using for receive tv stream.

Stage #4) Choose (( Stream/Save )) click Settings.

Stage #5) In the settings window check (( HTTP )) and Address field type 127.0.0.1 and Port field type 1234.

Stage #6) In the Encapsulation Method section, choose (( ASF ))
In Transcoding options check Audio codec and choose (( mp3 ))

In the Stream output MRL section it should be like this.

Code: Select all

:sout=#transcode{acodec=mp3,samplerate=44100}:duplicate{dst=display,dst=std{access=http,mux=asf,dst=127.0.0.1:1234}}

Stage #7) Now you start-up the VLC Player 0.9.0-svn from the cmd.
Go to Start -> Run and type in cmd then press enter.
Locate where VLC Player 0.9.0-svn are installed.

When you find where it is located then type in the cmd window::

cd ((your VLC Player 0.9.0-svn path))

and type in this code::

Code: Select all

vlc --sout "#transcode{vcodec=FLV1,acodec=mp3,sameplerate=44100}:std{access=http{mime=video/x-flv},mux=ffmpeg{mux=flv},dst=0.0.0.0:8080/stream.flv}" http://127.0.0.1:1234 --loop -vvv --color -I dummy

Stage #8) Start-up FLV Player and go to url… button in the address bar type in
http://127.0.0.1:8080/stream.flv


Have you done all the stages right then you should see your flv streaming is working.

[alrama]

thank you for share your solution, toejam.

I attempted to replicate it on my multicast+MPEG-TS+MPEG4 stream. Maybe this one is more critical to manage by ffmpeg codecs because VLC-0.9.0-SVN crash again !
If I have well understood, you suggest to use an intermediate HTTP+ASF+MP3 format to realize it. My source stream is already a network stream so I started a VLC 0.8.6 instance to grab it (bypassing TVU Player first-step) and stream out the intermediate format. Then I run a VLC 0.9.0-SVN instance from command line in the same way you did.

[dionoea]

This is a guide how to stream flv from local computer only.
I've only tested in local computer so if anyone have tried to connect with two computers or other devices like computer (server) and console (client).
Please send a PM to me and describe how you did it.

Since you use "0.0.0.0" in the dst IP address, the server should already then listen on all addresses, which means that you can access it from an other computer using http://<server ip>:<server port>

Note that you can simplify your output command quite a bit and add video and audio bitrates:

Code: Select all

vlc --sout "#transcode{vcodec=FLV1,vb=<some bit rate for video>,acodec=mp3,ab=<some bit rate for audio>,sameplerate=44100}:std{access=http,dst=0.0.0.0:8080/stream.flv}" <some input> --loop -vvv --color -I dummy

[alrama]

No kind of response ? Kind of: you are wrong, your source isn't good to encode to, we have some problems on flv streaming yet , we wont do it anymore, ...

[dionoea]

It's most likely due to a Windows specific bug. Just to make sure, can you dump 1 or 2 MB of that input ts stream, try to encode the dump and see if it still fails and if it does host the file somewhere so I can give it a try? (I only run linux, but at least I'd be able to confirm that it's somehow a Windows related issue.)

[alrama]

Thank you dionoea, I did it. Convert/save (input recorded no conversion) a couple of MB of source netstream. Then I attempted to stream it by:
"C:\Documents and Settings\id\Desktop\vlc-0.9.0-svn\vlc.exe" --sout=#transcode{vcodec=FLV1,acodec=mp3,sameplerate=44100}:std{access=http{mime=video/x-flv},dst=0.0.0.0:1234/stream.flv} "c:\Documents and Settings\id\Desktop\dump.mpg"
It crash again.
So I put dump.mpg here.
If Linux is able to manage it I could afford to build VLC on it

[thommyboy]

hi toejam,
is this the only (simpliest) way to make vlc stream flv?
flv is getting so important- i was just hoping someone
yould implement it in vlc directly
cheers TOM

It is implemented in VLC directly.

@alrama: I haven't had time to give it a try yet. I might have time today.

[alrama]

thank you dionea and toejam, now I'm be able to get it works !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
You both were right.
First of all I managed to build VLC 0.9 on Linux (only when Wiki was up again) . Using that one I got "unable to write header" (or something so) but none crashed here. So I used a 0.8.6c instance to first convert source stream piped to my brand new 0.9.0 to finally stream out "much wished" http://0.0.0.0:1234/stream.flv .

best regards to you all and I wish a long life to Videolan project

[thommyboy]

it is? but not on windows?
i can use flv as input but the resulting output stream
is not flv, only asf, mpeg supported when creating
a http stream

[alrama]

For my experience, yes. Maybe I could have made some mistakes, building VLC on windows, maybe it could work on Windows too. Anyway this is what I did there:

• Downloaded and setup Cygwin+Win32 contrib as in wiki

• Downloaded Lamemp3 sources, ./configure, make, make install

• Downloaded ffmpeg sources, ./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --enable-network --extra-cflags=-I/usr/local/include --cc="gcc -mno-cygwin" --enable-libmp3lame --enable-protocol=rtp --enable-protocol=udp --enable-pp --enable-gpl --prefix=/usr/local --extra-ldflags=-L/usr/local/lib , make

• copy builded libavcodec.a and libavformat.a over win32 contrib folder

• Downloaded VLC src, ./bootstrap && CPPFLAGS="-I/usr/win32/include -I/usr/win32/include/ebml" LDFLAGS=-L/usr/win32/lib PKG_CONFIG_PATH=/usr/win32/lib/pkgconfig CC="gcc -mno-cygwin" CXX="g++ -mno-cygwin" , ./configure --enable-sdl --with-sdl-config-path=/usr/win32/bin --disable-gtk --enable-nls --enable-ffmpeg --with-ffmpeg-mp3lame --with-wx-config-path=/usr/win32/bin --with-freetype-config-path=/usr/win32/bin --with-fribidi-config-path=/usr/win32/bin --enable-caca --with-caca-config-path=/usr/win32/bin --with-xml2-config-path=/usr/win32/bin --with-dvdnav-config-path=/usr/win32/bin --disable-cddax --disable-vcdx --enable-goom --enable-twolame --enable-dvdread --disable-gnomevfs

• make, make package-win32-zip

maybe someone can pick up which was my mistake(s) here.

[dionoea]

And that doesn't work?

What ffmpeg version are you using? What configure flags did you provide in ffmpeg?

[alrama]

ffmpeg source tarball: ffmpeg-export-2007-05-22

ffmpeg configure command:

./configure --target-os=mingw32 --enable-memalign-hack --enable-static --disable-shared --enable-network --extra-cflags=-I/usr/local/include --cc="gcc -mno-cygwin" --enable-libmp3lame --enable-protocol=rtp --enable-protocol=udp --enable-pp --enable-gpl --prefix=/usr/local --extra-ldflags=-L/usr/local/lib

[dionoea]

Should be fine ... although you should always use the latest ffmpeg version (ie svn trunk). But FLV streaming definitively worked in may. Can you try adding --disable-swscaler to the ffmpeg configure line?

[alrama]

I rebuilt all (ffmpeg with --disable-swscaler) and run again. Same result. I put messages level=2 and post recorded output. I'm going to spend some weeks on holiday so I won't be here for a while ...

cheers

You might want to try using samplerate instead of sameplerate in transcode Your mp3 has a 48 kHz samplerate and FLV can only use 44.1 kHz, 22.05 kHz and 11.025 kHz.

[alrama]

Yes Antoine I already do it on Windows and Linux. My command line:

cd "\Documents and Settings\id\Desktop\vlc-0.9.0-svn"
"vlc.exe" --sout=#transcode{vcodec=FLV1,acodec=mp3,sameplerate=44100}:std{access=http{mime=video/x-flv},dst=0.0.0.0:1234/stream.flv} udp://@239.255.100.101:7003

[dionoea]

samplerate !!!!!! not sameeeeeeeeeeeeeeeeeeeeeeeplerate.

[alrama]

You're right. On windows I made a mistake. Corrected but nothing changed. Reposting new vlc-log.txt:

I can't see any error. Can you try outputing to a file instead and playing that with VLC? (std{access=file,dst=somename.flv})
