Transcoding woes on a LG 42LE5900-ZA

PostPosted: Tue Dec 20, 2011 11:07 am

All,

I am coming to my wits end, and could really do with some help.

I am trying to play HD AVI files of motor racing on a LG 42LE5900-ZA. The files have the correct DAR of 16:9, but they display as 4:3 on the screen. After e-mailing LG support the answer I got from them is that their TV's ignore the aspect ratio, they have no plans to correct that, and I would have to stretch the frame size to get it in Widescreen.

The AVI's are currently encoded in H264.

I have tried encoding them to MPEG4, but I get horrible pixelation and a really poor quality video stream.

I have tried encoding them to libx264. When I do a transcode with no options, I get a jerky video with stuttering motion. If I use the HQ or MAX presets, the TV rejects it as an invalid file.

The current frame size on the videos is 1440 x 1080, and I am trying to stretch it to 1920 x 1080. I know that I have to transcode to change the frame size.

I am not bothered by the Audio, If needed I can loose that.

After all that background, can I please have some help on what is the best codec to transcode to and keep the quality? Should I be trying for 720p rather than 1080p? Should be looking at going to mkv? If so, which codec can I use for that?

Any help anyone can provide will be much appreciated. If I can provide anything else to help, please let me know.

  Code:
Command:
ffmpeg -i Abu-Dhabi-orig.avi -vcodec libx264 -vpre libx264-max -s 1920x1080 -aspect 16:9 -acodec copy Ws-attempt18.avi

Original then result:

you should be able to do mpeg4, but make sure you use -sameq parameter otherwise FFmpeg defaults to a very bad quality output.

Thank you.

I did not know about that switch. I'll give it a go and let you know how I get on.

Cheers
Drew

Hi there,

Well, I gave it a go as follows:
  Code:
ffmpeg -i Abu-Dhabi-orig.avi -codec mpeg4 -sameq -s 1920x1080 -aspect 16:9 -acodec copy Ws-attempt19.mp4


The file size did inflate a bit:
  Code:

I put it on the serviio server, where I have tried mp4 files before:
  Code:
serviio@chpe-d9-001554:~/Media_files> ls -lh Ws-attempt1*.mp4
-rw-r--r-- 1 serviio users 2.4G 2011-12-06 08:10 Ws-attempt13.mp4
-rw-r--r-- 1 serviio users 8.8G 2011-12-06 19:51 Ws-attempt14.mp4
-rw-r--r-- 1 serviio users  42G 2011-12-20 17:06 Ws-attempt19.mp4
serviio@chpe-d9-001554:~/Media_files>


When I look at the library from the TV, the file does not show up. There is an error in the log file:

  Code:
2011-12-21 12:25:43,488 INFO  [LibraryAdditionsCheckerThread] Added file 'Ws-attempt19.mp4' (title: Ws-attempt19) to Library

I have checked the file against the two other files there, and the ffmpeg info looks almost the same:

The only difference I can see is that the version of the encoder is a later version.

Is 42Gb too large for Serviio to serve out?

serviio probably doesn't support mpeg4 in mp4 container. Try to wrap it back to AVI by providing

  Code:
-f avi
