MP plugin for Video Transcoding (2 Viewers)

[Noelix]

Fabrice, I've been testing 1.0.2 and it's been working wonderfully for me. TVE3 support is great, its scheduling properly and encoding properly as well. I did notice that encoding from MPEG2 to XVID using FFMPEG worked perfectly. That said, using Mencoder produced a bit of audio/video desynchronization in the final file. I'm just using FFMPEG instead so it's no big deal for me but some others might experience the issue if they use mencoder.

Again thanks for all your work. I'm going to look into creating an installer for this and updating the plugin page on the mediaportal site with your instructions.

Issues with FFMPEG and AC3

Brilliant plugin! I have been looking for something like this for a long time. I use TVE3 in a single-seat environment and after some trial and error, I have got the transcoder plugin working quite well with mencoder. I am transcoding recorded TV that is saved in .ts format. With Xvid @720x576, video bitrate of 1,534kbps and MP3 @192kbps my transcoded files are about 25-30% the size of the input file with very decent quality.

However, whenever I try to change the transcoder settings to AC3, the output file is completely out of whack. Video frames are flashing by in what looks like some kind of fast forward mode and only part of the audio can be heard. Not a big issue as it works with MP3, but I was unsure wether I could get 5.1 audio without AC3.

The other issue I have is that transcoding doesn't start if I use FFMPEG instead of mencoder. Not a big issue either, but some people on this forum seem to believe that FFMPEG gives better quality.

To conclude, I would like to know if I need AC3 in order to have 5.1 audio in my transcoded files. In addition, I am curious about which bitrate, framerate, resolution, etc. others are using in order to achieve good quality transcodes of recorded TV.

Hat off for Fabrice, for creating such a great plugin!

Cheers,
Tomas

Hello tomoqv,

Can you provide me the log file (in debug level) of MP and TV server when you try to use FFMPEG to find the problem.

For ac3 is more complex, the AVI container is not designed to store AC3 stream may be you can use the MP4 container to encode with H264/AC3 it works correctly. The disadvantage is than the video cannot be read on all divx player.


I posted an update

Changelog 1.0.3:

* change the bitrate generation with FFMPEG encoder
* fix all Skins to display correctly the enconding statisticals
* Fix 'settings' window to allow tomodify hour of scheduler and nb of jobs
* Fix PSP profile
* Fix ipod/iphone profile
* Fix cleanup function onc eencoding jos has finished (not delete (xml, txt files)

Here are my log files. I have upgrade to version 1.03 on both TV Server and client, but FFMPEG transcoding still fails. I couldn't find a relevant log file in the TV Server log directory, only TsWriter.log (with the size of 26MB!), Streaming Server.log and tv.log.

Rgds,
Tomas

Hello,

I need tv.log with Debug level, thanks

Hello,

I need tv.log with Debug level, thanks

Sorry, here it comes along with the other two files from the same transcode. I hope this is what you need - tv.log only contains 7 lines.

Hello

it is exists an issue with TS file and FFMPEG. If you would use FFMPEG with TS file add the parameter '-acodec copy' in your profile in extra parameter. The audio stream will be not compress.

Tip: don't specify the quantizer settings the auto param is good

Bye

Thank you, that did the trick. However, I will stick to mencoder as the ffmpeg transcode I did with the DVD_Quality profile was notably worse than the ones I had compressed with mencoder at similar bitrates.

Best regards,

Tomas

I change the bitrate generation for ffmpeg , i specify a max bitrate for FFMPEG and mencoder it is a average

so with FFMPEG the compression is more important and respect the birate (max) then mencoder the birate can be exceeed the value of profile

So if you would a better quality with FFMPEG , just increase the bitrate.

Having a few problems
I am recording tv in .ts format, im using Xvid @720x576, video bitrate of 1,534kbps and MP3 @160kbps.

When i use FFMPEG and the aspect ratio is set to auto or 16x9 it converts it to 4x3 but the audio is in sync with the video.But then when i use Mencoder it gets converted to 16x9 which i want but the audio is out of sync.

I can attach logs if you need just let me no which ones.
