Transcoding all uploaded videos to FLV

yep. i use -strict experimental on my production server using this module with no ill effects. this is why the "extra ffmpeg flags" field is there in the admin.

if i get any reports of using the experimental aac codec producing consistently bad results then i'll change it to allow libfaac or other iterations of libmp3lame, but for now, i've heard nothing and, as i mentioned, i use it also and not had any problems with it to date. ymmv.

let me know what sort of results you get.

Dan

if you get something that works, please do share.

this is something i've already noticed. however i've not ventured myself into the work of executing tasks using a cronjob rather than doing them there and then. i'm currently working on an amazon s3 module which has to have a crontab run task to upload the contents of g3 to s3. once i've got me a decent method for this, i'll apply the same logic to transcode so that this is also possible. this'll give more of the youtube-esq experience where you just upload the video and then the server goes off into the background and transcodes the video into the relevant formats.

this module is for gallery3 only. it won't work on gallery2. this is what you're looking for.

Hmm, having difficulties. Something does not seem to be creating anything in g3/var/modules/transcode/

I had to manually create log to get logs to work... and logs are saying that /flv doesn't exist...should I be having to create these manually?

After creating transcode/flv and chmod 777 it, it now works...

Another question, I have only chosen 1 resize option (360p) on the movie page though, this is the ONLY option, where is the original size?

I am having some problems with transcoding videos in conjunction with server add module. It seems that sometimes, I end up with multiple versions of the file I uploaded with the second and third filename having a -NNNNNNNN.flv appended to the file name where N is a series of numbers. The original file and the copies get passed on to the transcode module and so after the transcode job, they appear all in the gallery album. I did modify the transcode module by adding

if (preg_match('/(\d*) kb\/s/', $line, $bitrate))
$file->audio->bitrate = $bitrate[1];
}
}
+ if (empty($file->video->width)) {
+ $file->video->width = "1920";
+ $file->video->height = "1080";;
+ //just assume that all videos have audio for now
+ $file->audio->has = true;
+ }
return $file;

to helpers/transcode_event.php

And had to rename my source videos so they have a .flv extension (to get by Gallery 3's filename limitation) . My source videos are AVHCD.
The problem happens when I select more than 2 resolutions for transcoding.

I would appreciate any insight.
Thanks
Chris

Hello,

I have installed transcode10.zip in G3 on a hosted server. I also manually installed ffmpeg 0.6 in my directory and set rights to 755.
When I try to configure transcode settings and set the ffmpeg path to ../../ffmpeg (this is the path i put in the Admin advanced settings), it fails.

I put the ffmpeg path, then click to verify ffmpeg path and it shows "Empty file path provided".

Not sure what I am doing wrong.

Thanks for the great work on the module.

Laurent

Is someone using this module on Debian?
I start thinking ffmpeg bundled with Debian isn't comptatible with this modules.

I have nothing in logs of G3, nothing in logs of transcode module... it simply doesn't work for me :/
