Avi support

[jorm]

Bart,

That is interesting. And probably worth looking into eventually.

One thing I would like to figure out why it is happening is the time that the transcoded mpeg shows is all confused. I wonder if it is vlc not fixing the header on the mpeg. If someone has another avi that they can transcode using another tool. DNKO or something else can you check the time for me to see it if is working.

I figure since it does not correctly show the time probably results in the skip forward and back failure.

I need to work on a executable for killing a process given the process name.  So when we stop transcoding we can kill the vlc process.

Barts suggestion might be better in the long run but you can find a free kill exe that does what you need at:

Thanks for the link.  The license prevents redistribution. I have writen my own kill that shoud do the same thing. I will add it to the next release.

When I first tried the AVI support I found that I got video but no audio on any of the files I tried.  An error message in the VLAN window suggested that the problem was with the acodec=mp2 option.  After a bit of googling I found a solution to a similar problem was to use acodec=mpga instead so I changed this in transcode.bat and it worked fine.  Any idea what I'm missing that stops acodec=mp2 from working (presumably it works fine for others).  Is there any particular advantage to one or the other?  I did notice that with the mpga codec the sound was very loud (relative to mpg/mp3 playback on the same box).  I'm using VLAN 0.7.2 by the way.

Overall, this is looking like a great step forward.  The one thing that keeps me from switching to GBPVR altogether is the lack of AVI support (I still have to switch to the Hauppauge software from time to time).  Keep up the good work - it is much appreciated!!

I am going to play with ffmpeg again. I want to see if that handles the time better.

Hopefully someone whom knows more about vlc might be able to answer your questions. I havent had time to playwith it much. I had tested it with the latest version v8.x

[Bart]

I have sent a question on the PS timeheader to the vlc-devel list but it seems it didn't arrive?! So I rejoined the list and see if it works now.

As far as I know ffmpeg en mencoder (mplayer) and VLC use the same libraries for the handling of the mpeg-streams... I wonder if the ffmpeg works (but if so, it would be better!

I'll start testing with vlc 0.8.1

with mencoder:

mencoder.exe v:\killbill.avi -o y:\movies\transcoded.mpg -of mpeg -ovc lavc -lavcopts vcodec=mpeg2video -oac lavc -lavcopts acodec=mp2

Probably need to fiddle with some parameters.

This plays in MVP and pause works ff works (but in some cases it crashes), but length of asset is only read when the movie is started - so it still is NOT the complete duration (but the transcoded length).

It seems that mencoder is a lot "nicer" to the cpu, only has limited control (ff, quit from an external IO)

[jorm]

I like mencoder.  It allows me to skip, see accurate time(The transcoding time is what we would like to see, so you know how far you can skip.).  And fast.    

Might be useful to create an app that walks the directories of shows older than a certain date and xvids them.

This is slightly offtopic but relevant. I am trying to convert DivX AVIs into MPEG so I can stream the video through my mediamvp without using up processor cycles on my computer used in the DivX decoding. I tried using ffmpeg to do this but I end up with a slightly stretched image that only occupies the top half of my TV screen when played through GBPVR or the normal mediamvp interface. The bottom half of the screen is completely black as well as the sides (this is a 16:9 TV). Can anyone make some suggestions as to what I am doing wrong? Here is the command I am using:

ffmpeg -i show.avi -b 2000 -vcodec mpeg2 show.mpg

I've tried using both 4:3 and 16:9 for the "aspect" setting, and this does not solve the problem. I would appreciate any help...

As tipstir has suggested in other threads, try DIKO - should get you going in thr right direction,

cheers,
Colin.
