[11:27:56 CET] <LeadAssimilator> I'm noticing an issue with ffmpeg's aac encoder producing invalid output when ffmpeg is crosscompiled for windows.
[11:28:15 CET] <LeadAssimilator> Native msvc builds appear ok and native nix builds seem ok, but crosscompiled win isn't.
[11:28:25 CET] <LeadAssimilator> the errors show up on decode such as:
[11:28:25 CET] <LeadAssimilator> Number of bands (56) exceeds limit (44).
[11:28:29 CET] <LeadAssimilator> invalid band type
[11:29:11 CET] <LeadAssimilator> I suspect a compiler issue, but it is proving difficult to track down
[11:30:05 CET] <LeadAssimilator> anyone else experience this?
[11:31:44 CET] <BtbN> The vast majority of available Windows builds are cross compiled
[11:32:10 CET] <LeadAssimilator> yes, i can reproduce with zeranoe builds and my own builds
[11:32:32 CET] <BtbN> Open an issue then.
[11:34:23 CET] <LeadAssimilator> well i'm not so sure it isn't a mingw compiler issue
[11:35:32 CET] <BtbN> gcc is gcc
[11:35:46 CET] <LeadAssimilator> ehh not quite
[11:36:04 CET] <BtbN> I've also been using the aac encoder with zeranoes build for ages, and never had issues. So maybe you are just using it wrong?
[11:37:50 CET] <LeadAssimilator> doubtful given it works in nix native and win native
[11:38:03 CET] <LeadAssimilator> it is highly input dependent too
[11:38:28 CET] <BtbN> Just open an issue then and make sure you add all neccesary samples and commandlines.
[11:41:47 CET] <LeadAssimilator> oh lol didnt see u in devel, ok
[12:34:16 CET] <LeadAssimilator> ugh still havent received verify token mail from trac
[13:27:52 CET] <Zucca> So it seems that I cannot encode with h264_vaapi and use mkv container. However is it possible by using complex filters? Or do I need to afterwars copy-stream the mp4 into mkv?
[13:29:08 CET] <Zucca> I'd want to use mkv to be able to just copy the audio and subtitles, but only re-encode video.
[13:29:10 CET] <BtbN> The container has no effect on the encoder whatsoever.
[13:29:51 CET] <LeadAssimilator> trying to upload samples...is the ftp host no longer active?
[13:30:22 CET] <BtbN> I don't think it is. Since a long time.
[13:30:38 CET] <Zucca> BtbN: Well it looks like all those vaapi encoders do require a certain container. I even get warnings like: No global header will be written: this may result in a stream which is not usable for some purposes (e.g. not muxable to some containers).
[13:32:08 CET] <BtbN> I'd expect that to get fixed by some bsf
[13:33:11 CET] <Zucca> BtbN: Ah. So it's kinda WIP encoder?
[13:33:17 CET] <BtbN> No
[13:34:56 CET] <Zucca> BtbN: Ok. What did you then meant? :o
[20:00:12 CET] <familiyaF> Hi, in my application I am transcoding 20 streams on 5 gpus using vaapi. I am observed that the process gets stuck after some time. Looking at the logs I see 'No More free VCE handles'
[20:01:57 CET] <familiyaF> what might be the possible reason?
