Transcoding Video to FLV for use in new JWPlayer

[lemay86]

Oh, HAH! Silly me. In the player settings I have to activate the new transcoders, it's not enough to enable them in the transcoding section.

So, now that THAT's squared away, I'm trying to transcode a h264 film in a avi container.

Nothing happens. The log says:

The two lines that are fishy I've bolded. I'm not sure about the last one, which looks like is what kills.

When I try to transcode a h264 packed in mp4 container, all I get is the following:

[2/4/09 10:43:46 PM MST] INFO PlaylistInputStream Opening new song d:\documents\Videos\movies\Action Adventure\Chain Reaction.mp4

and windows reports ffmpeg.exe crashed. The first time it took a while for ffmpeg to crash, while subsequent crashes happened sooner and sooner after starting the transcode.

I'm going to try a different build of ffmpeg and also trying a full conversion (not streaming) to another file to see if that works.

Are you doing this on Windows of Linux?

That first error message you were getting from ffmpeg was probably due to the 5.1 sound try adding -ac 2 to you ffmpeg conversion command it will force it to 2 channel audio.

The command I use is:
/usr/bin/ffmpeg -re -y -i %s -ar 44100 -ac 2 -sameq -f flv -

That command works for the avi's and mkv's I have on my system.

Yh, I have tried streaming .flv files and the sound will play but the cideo won't. Even in fullscreen mode? Do I have to set up transcoding for this?

How do I go about enabling the video of an .flv file?

PS- Thanks for your previous fast response.

Have you followed the instructions to change the player height? When I leave my height at 20 it wont play the video but sound is fine. Just set your height above 20 and it should work.

Hey,

This works great! Anyone know how to pass a param to allow "rewind" and "fastforward" or even "prev" and "next" buttons to appear so that I can go to the next song on the playlist from the jwplayer?

Thanks!

[thenewbie]

I can't get streaming to work with the web player.

VLC streaming works perfectly and the ffmpeg settings (ffmpeg -re -y -i %s -ar 44100 -ac 2 -sameq -f flv -) work perfectly, too. But the webplayer won't play any flv files (even "real" .flv files - I used this sample (http://www.mediacollege.com/adobe/flash/video/tutorial/example-flv.html)

When I start playback (fullscreen or minimized) nothing happens - the play button turns to a pause button and quickly turns back to a play button.

In the log there's only the message "admin started playback" and a second later "admin stopped playback".

Any suggestions? I've already tried the "hack" to add one pixel, but I can't get a video/audio output, though.

Thx in advance

[freeflysage]

I believe I have this all set up, and the logs show it transcoding from avi to flv but all i get in the flash window is an animated circle counting the loading. It appears to transcode the entire file, but I never get video.

Anyone else with this problem?

running ffmpeg from todays svn build and jw flash 4.5.230.

transcode options of ffmpeg -re -y -i %s -b 512kb -ar 44100 -ac 2 -sameq -f flv -

Also the streams play in VLC if i use external player with playlist...

Thanks

hmm strange. You obviously added the .flv to the Music mask setting and that should be all that is required to play the .flv.

I couldn't test those files due to wget failing on them and me being to lazy to ftp into my server, but I used this file:
http://www.mifos.org/product/demo-the-s ... _demo4.flv
and it played perfectly. I'm using the standard JW player that came with subsonic 3.6. I'm assuming its the same as subsonic 3.7's flash player version if that is what your using?

Also are you using apaches proxyPass or lighttpd's mod_proxy to pass requests from domain.com to domain.com:subsonic_port? I noticed when I did that in lighttpd my files that I transcoded would transcode completely before they played (a long loading circle). This was for the standalone subsonic. This might be your problem as well freeflysage or at least sounds like it.

I'm having this exact problem. I'm using Windows Server 2008 running as a standalone installation and the latest build (18639) of ffmpeg here http://tripp.arrozcru.org/.

If I try to play any video in the web player (including streaming an flv file directly without transcoding), the percentage counter spins and counts up to 100, resets to 0 and starts counting again (repeating this indefinitely). Also, if I use the external player setting, both media player classic and vlc immediately give up.

When I try to play an avi file (transcoded to flv using 'ffmpeg -re -y -i %s -ar 44100 -ac 2 -sameq -f flv -'), media player classic reports the following:

Code: Select all

http://xxx.xxx.xxx:nnnn/stream?player=12&suffix=.flv::Output

Media Type 0:

bFixedSizeSamples: 1
bTemporalCompression: 0
lSampleSize: 1
cbFormat: 0


Playing an flv file directly (I've added flv to the music mask list), I get the exact same error. If I attempt to access the stream URL directly in my web browser (http://xxx.xxx.xxx:nnnn/stream?player=12&suffix=.flv in the example above), my browser seems to download quite a lot of data, so it seems like subsonic is sending the stream. Furthermore, executing the ffmpeg transcode from a command prompt and redirecting the output to a file results in an .flv file which plays fine locally.

Also, attempting to play an avi file using media player classic without any transcoding results in media player classic saying "Opening..." without ever starting the video (even for extremely small (~33kb) videos).

However, if I set the player to external player with playlist, everything plays fine (both transcoded and not). Ideally, I'd love to get the web player working both so that I could watch videos on any computer with a web browser and flash installed without having to depend on additional software, and so that I don't have to juggle several subsonic players with different settings depending on the type of content I'm playing. I have also tried doing a fresh installation of subsonic on a computer running windows server 2008 R2, and I get the same behavior.

It seems like maybe there is some sort of header/protocol issue that gets in the way of players properly determining the content type being streamed when subsonic maintains control of the playlist, but I could be wrong. Does anybody have any suggestions as to what I might try to get this working properly?

Hi Guys,
First off. This is really funny but that link about Jinzora is actually to my website

Also, I may have found a solution to this to get the Flash Streaming + ffmpeg working in release 3.8 for SubSonic. Im still testing out some bugs to see if its stable or not but expect a post here and on my site by tomorrow evening = ) (Saturday)


By the way, Love the software. Jinzora is nice but subsonic seems so much cleaner..

Hello,

I've been toying with ffmpeg (windows binary found here) to get it to transcode any of my .mp4, .avi, .mpg videos to flv. Many of my videos are HD and around 6-10GB. FFMPEG does support on the fly transcoding and from what I understand can output to stdout. I have a rule set up in transcoding that is "ffmpeg -re -y -i %s -f flv" but it doesn't work. All my log says that it starts loading the 'song' and nothing else happens. My bandwidth goes crazy, but I don't know what it's doing.

Does anyone here have experience with ffmpeg? The following page shows how to get it working with Jinzora, and might be a good starting point.

Have you had any luck with 3.8? I was interested in mod-ing my subsonic with the jw player and flv streaming.

Thanks,
