(MPC bug) RV10 + HE-AAC = Frame Dropping

[Sirber]

Hi

Using the same settings:

RV10+cook = all FPS
RV10+he-aac = constant dropped frames

all while encoding... :confused:

[edit]

renamed the title...

I think what you are seeing is a playback problem in MPC, which will be fixed in the next release. Encoding should be OK, it never drops any frames due to CPU scaling for file-to-file encodes. With corrected DLLs in RP10 (not yet available, will let you know) the file should also play back fine. Here is what Gabest wrote when I reported this:


With the current release out the audio renderer only receives the first
frame per packet with the right timestamp, you have to wait the next one to
play he-aac smooth. The problem was that I didn't notice that he-aac frames
contian twice the number of samples, and using the same formula the
timestamps of intermediate frames became wrong.

Looks like the same problem. Same thing on BSPlayer.

[Sirber]

Gabest said the bug was corrected, but I can't find any new build. 6.4.7.5 is still buggy.

try using "overlay mixer"

[Sirber]

It's a bug with the splitter, not the renderer :)

[bond]

well i always get frame dropping when not using overlay mixer, i guess the reason is my 866 cpu

[Sirber]

might be the CPU :D

[Sirber]

RMVB problem fixed with lastest splitter from gabest :D
dunno for MKV...

I just tried the new mpc version....
the he-aac + rv9ehq playback is perfect......
Is there any way to use he-acc with less than 64k bitrate?
Will lower bitrate be added in the future?

[Sirber]

not at the moment, maybe later. Since HE-AAC is not an oficial Real codec, who knows :)

I mean in the rmvb container......
everyone knows how to play a rmvb extension file but not everyone knows how to play a mkv extension file.......
will there be a tool such that it will mux matroska content or anyother content in to an rmvb container........

[Sirber]

IIRC, there is no external muxer for rmvb.

[Dark-Cracker]

hum there is an rmvb muxer :) just wait and see :)
