How to convert HD video to play back on Vega

[Guest SilentMobius]

Hi can you point me to where you grabbed FFMPEG from that allow me to use that command easily?

Compiled it from source, on my Ubuntu server using this guide (In my case the 10.04LTS one):

[Guest remlap]

Okay you've lost me, any help just using the ffmpeg for windows exe?

[Guest arad85]

Google "ffmpeg windows binary".

To be honest, if you're asking how to find the binary... ffmpeg may not be for you.

[Guest arad85]

Ok, it looks like the main profile support is pretty weak right now, but the following ffmpeg command-line produces playable 1080p results using the baseline profile.

ffmpeg -i INPUT_FILE -vcodec libx264 -vpre slow -vpre baseline -crf 20 -b 5000k -threads 0 -acodec libfaac -ab 128k -profile aac_low OUTPUT_FILE.mp4

Hi. Thanks for this. Did you try 720 or 1080 main? 720 is supposed to be capable of main...

I've just converted a 720p MKV file to an MP4 that fits the Vegas screen using 1024x576 as the resolution, with the AVS Video Converter:

It looks great and plays perfectly with the stock player.

Hi,

This sounds like just what I'm looking for, but where do I enter these settings ? I can't see anything to change Format Profile to Main etc ? Clicked on Advanced and get options for Video Codec, Frame size, Bitrate etc

[Guest Gregga]

I am using Prism Video File Converter Plus (free download to PC)

just convert to .mov set average and max bitrate to max.

enjoy HD movies with super good quality + sound + no lip sync issues YAY

Interesting, ill have to give this a try tomorrow.

[Guest SilentMobius]

Hi. Thanks for this. Did you try 720 or 1080 main? 720 is supposed to be capable of main...

Tegra2 is supposed to be able to handle High on 720p and Main on 1080p but the Vega currently isn't up to that. We need to wait until we have the kernel source and see if we can pull in more recent versions of the nvidia libs. For the time being I'm going to stick with baseline, should I need HD video.

OK.. Thanks. I guess we're waiting for some software updates then :)

[Guest debs626]

I remember having a problem streaming .mkv's on the PS3, I used mkv2vob to get around it.

http://www.videohelp.com/tools/mkv2vob - its free

I dont have any mkv's on my laptop to test atm.

[Guest remlap]

Hi managed to get 720p and 1080p video playing from Handbreak but no 5.1 audio only stereo whatever I try.

Edit to add: I am assuming the vega can pass the raw audio through HDMI.

Edited December 13, 2010 by remlap

[Guest ricwales1]

not sure on passthrough but if for playback on Vega only then encode for stereo as 5.1 is a bit pointless.

just tried it on a 720p mkv.

first attempt gave me an mov file with no sound. i'm guessing that prism converter doesn't like dts soundtracks

i extracted the audio and video tracks from the mkv using mkvextract, converted the dts to ac3 with eac3to and remuxed to an mp4 with mp4box

the mp4 still stuttered and lagged on the vega

i ran the new mp4 through prism and it gave me:

copied the file to the vega and it plays well, no stutter, no lag :)

although the application is very simple to use, my only complaint would be that it uses just one core of my cpu

[Guest removed-14]

Try rockplayer for playback as I've found files where audio doesn't work in the standard player often work in rockplayer.

[Guest ricwales1]

for a paid for app I guess dvdfab would work on the PC.

[Guest warriorscot]

Massive problems with keeping audio in sync when it is running the software mode necessary to play the audio streams the vega cant handle.

heh, yeah I have rockplayer, I've been telling others to try it for AVI's with ac3 audio

The problem wasn't on the Vega tho, I tried the files before transferring them to the device. Prism converter just didn't convert DTS to AAC properly.

[Guest removed-14]

The only audio sync problems ive had have been through encoding. Ive found that if it playsback on my pc ok then it looks and plays the same on my vega.

[Guest warriorscot]

It depends really on the quality of the video file anything with high bitrate video and AC3 sound is massively out of sync. Sync problems in rockplayer are pretty across the board from what I have read from the developers forums so its not a vega exclusive thing.

Honestly I think its just a case of converting when neccesary and waiting for google and nvidia to fix the multimedia problems.

You would be right which I why I linked to the following which sheds some light on to the android platform and the lack of video handling within android its self.

[Guest warriorscot]

I read through some of that last week when I was researching the problem. Its an interesting read and I hope corecodec makes it out with something as soon as they have promised. However they are in for a rough go of it with google planning on making some major over hauls they are going to have to work hard to adapt what they already have to the upgraded framework. Personally I would have went with an outside solution and circumvented those problems but I get the integration argument over the long haul.

[Guest ricwales1]

Anything would be good right now. Fingers crossed were not waiting to long to try this one out.

[Guest arad85]

I'm confused... The stock player should handle video better than any other player as it should use the hardware acceleration. As far as I'm aware, NO player other than stock makes use of hardware acceleration. The conclusion? Anyone who expects a 3rd party player to paly any HD content is probably deluding themselves... It's likely to remain a sideline for the next few releases...

[Guest Qwertymon]

1024x600, at 25 to 30 fps, thats what ive done for most my files anyways and it works fine. I assume your using rockplayer? (I wish it was hardware accelerated, the tegra doesnt seem to be supported).

Rockplayer handles video way better then the stock player.

[Guest arad85]

Define "handle video better"... TBH, I haven't done much with video playing yet. I have a few media players and laptops throughout the house capable of playing full HD so it's a little redundant here (if it streamed, it might be a different priority for me). I also work from home, so there is no commute to worry about.

My feeling is that if you have to convert to play on the device, you might as well convert to one that is supported by the hardware. It's probably more efficient battery wise too...
