What is happening some files I am trying to convert shows a decoder lag. How can I overcome this.
What is a 'decoder lag'? The audio which has a delay from the video at a certain point?
I am not sure either.It simply has a black screen at the start of the video stating Warning:Nothing to output bframe decoder lag.
sounds like a codec issue
remove all the codecs/codec packs that you have installed on your comp and download and install ffdshow.
Virtualdubmod----->open file (avi for example)
stream list------->save stream as .wav
stream list-------> disable stream
---------------> start frame server (start--->save, give a name)
TMPGenc----->browse video file(go where u saved the file and load the file.......vdr,(show all files)then browse audio and
load the .wav u saved be4.----> Load ---->click on dvd pal and start. Video and audio are ok after 4-5 hours.
Sounds like you are talking about an XviD file that has bframes that aren't packed. The message is there because the video is being opened via VfW which can't properly handle bframes due to its one frame in one frame out design.
You could increase the directshow priority in TMPGEnc so that the file is opened via dshow and not VfW.
if you're gonna frameserve, make sure you use direct stream copy, unless you want to use filters.
why? cause full processing converts to rgb, which will slow you down, and may reduce quality.
or better yet learn avisynth
TMPGEnc converts to RGB24 anyway.
didn't realise that.
what about those libavcodec encoder?
quenc, hcenc, etc.
HC isn't libavcodec based. It was written from scratch in fortran.
That said it like all libavcodec based apps uses YV12. Newer CCE versions also accept YV12 however I still think they process internally YUY2. Not sure if any commercial encoders process in YV12, well other than maybe VSO's divxtodvd, that is if it actually uses libavcodec for output and not just input.
If you get the message "Warning: Nothing to output bframe decoder lag". Is as mentioned above is because of the VFAPI plugins in the Options > Enviromental settings > VFAPI.
Just right click on
"DirectShow Multimedia File Reader" and select "Higher priority" twice (until it's on top of the list).
Separate names with a comma.
