MPEG4 Encoder w/ Threading

[sdhays]

I'm evaluating the MPEG4 encoder included in the Linux IPP5 samples. When I encode using threading (-r option), the program doesn't exit; it hangs until receiving SIGINT. The MPEG4 file is fine, though; it seems that the encoder thread simply never figures out that its work is done. If I don't use the -r option, the program exits with a nice report at the end. Does anyone else have this problem?

I have the same problem~~

I'd also like to ask if this issue has been resolved in the IPP 5.1 samples, which I'm expecting will come out very soon (Q2 ends this week, doesn't it?).

Hi Scott,

yes, we also discovered this issue. It definetely will be fixed in IPP v5.1. But for IPP v5.0 there is quite simple workaround:

you need to modify umc_mpeg4_video_encoder.cpp, line 150
return UMC_OK;
to
return (sts == MP4_STS_NODATA) ? UMC_END_OF_STREAM : UMC_OK;

It should solve this issue.

Vladimir
