[XviD-devel] Fw: Fw: libxvidcore decompression

[reno reballos]

Hi Master Stephan Assmus,

<You did not commented on my point that you might have to call xvid_decore() 
<*multiple* times until you can use a frame in the output buffer. See my 
<other mail

i have tried this method but, still i got no output data from the xvid_dec_frame.output.plane[0],  i have follow closely the decoding process and assigns values in it like what xvid_decraw did and also the link that you've given me....

<Are you calling xvid_decore() multiple times in a loop and 
<feeding it new data, checking the decoder stats after each time to see if 
<you have decoded the first frame successfully?

yes, i tried this method too and i got no data too, i check the xvid_dec_stats.data.vol.height and xvid_dec_stats.data.vol.width, yes, it does give me the width and the height corresponding to the width and height that the input file that i have, which means decoder was able to determine the video resolution which means too that i have input data but in return does not gave me an input

isn't that i have to call XVID_GBL_INIT, XVID_DEC_CREATE and XVID_DEC_DECODE every time i decode or i have to call XVID_GBL_INIT, XVID_DEC_CREATE once and  XVID_DEC_DECODE whenever i have frame to decode and XVID_DEC_DESTROY when i do finish the decode, right now in my application i call XVID_GBL_INIT, XVID_DEC_CREATE and XVID_DEC_DECODE whenever i decode a frame..

<I thought you wanted to calculate the uncompressed frames requirements. 
<For the compressed stream, it is a function of how you setup the xvid 
<encoder.
is there a formula or basis to this that i can calculate in advance how much data i will have whenever i compress a frame and also in the decoding, how can i know that i have decode 1 single frame?


thank you..looking forward to hear from you...

regards,
reno

You did not commented on my point that you might have to call xvid_decore() 
*multiple* times until you can use a frame in the output buffer. See my 
other mail. Are you calling xvid_decore() multiple times in a loop and 
feeding it new data, checking the decoder stats after each time to see if 
you have decoded the first frame successfully?
