Anyone running MythTV 31 on 32-bit x86 with nVidia card?
My trusty old frontend is a 32-bit x86 machine with a GT 430 nVidia card.

Quite some time ago I upgraded to MythTV 30.0 but ended up reverting
back to 29.1 because I had some issues with some (though not most)
h264 videos. Specifically, some h264 videos would fail the VDPAU
decode and fallback to software decoding. These were videos that used
VDPAU with no issue in other players like xine, and also in MythTV
29.1. This was never resolved and was an issue that apparently
couldn't be reproduced on 64 bit systems.

My understanding is that the FFmpeg hardware acceleration code has
been radically changed in version 31.

As per the subject, if anyone is running MythTV 31 on 32-bit x86 and
is using an nVidia GPU, it would help me enormously if they could test
this example:

http://jell.yfish.us/media/jellyfish-60-mbps-hd-h264.mkv

...and see if it uses VDPAU decoding, which can be determined during
playback from the menu under Playback -> Playback Data.

That would be a huge help if anyone can test that. Thanks!

Tom

I have a 64-bit Fedora installation with a GT 430 card - not exactly
what you are asking for, I know.

But for me, the video Playback Data shows h.264 ffmpeg

Wow. So it's NOT using VDPAU, and that's with MythTV 31? That is
really not good news at all. Do other h264 videos use VDPAU? That
sounds like a significant bug to me. Even on my 32-bit system that
video uses VDPAU without issues in xine, mpv, and in MythTV 29.1.

When I was temporarily on 30.0 I posted comments about this on this
(semi-related) bug, but at that time apparently nobody using 64-bit
could duplicate this one:

https://code.mythtv.org/trac/ticket/13223

As noted there, the error that caused it to fallback to software
decode was this:

2019-05-17 10:37:09.222935 E [14504/28060] Decoder
avformatdecoder.cpp:3785 (ProcessVideoPacket?) - AFD: video
avcodec_send_packet error: Invalid data found when processing input
(-1094995529) gotpicture:0

I'm hesitant to update, though I'm going to have to soon, as (for a
number of reasons) I can no longer compile MythTV 29.1 on my Gentoo
system. What's worse is that, since I'm running 29.1 I can't very well
log a bug or test any of this.

I'd be interested to see what others find testing this...with 32 or 64
bit. Thanks for the reply! That's significant for sure.

That file is encoded using the H.264 High@L5 profile. I am not sure
if a GT430 can play that profile, so that may be why it is dropping
back to using ffmpeg. You only need High@L4.1 for playing BluRay, so
a lot of earlier Nvidia cards did not support higher than that, IIRC.
In v31 (using the new rendering code), when I play that file using
mythavtest on my GT1030, it plays using VDPAU.

Again though, that can't possibly be the issue because it can use
VDPAU on that same system and GT430 in MythTV 29.1, xine, and mpv.
Clearly has to be a software issue and not the card.

Having said that however, it is interesting that it uses software
ffmpeg (even on a 64-bit system) for George above and not for you. I
suppose it could be a MythTV issue that only occurs on certain cards.
Again though, no question that my card itself absolutely can handle
that file.

But you may well have to tell it to use VDPAU or NVDEC in your playback
options in the frontend. Frontend setup > Video > Playback, iirc

If you mean the playback profile, my default has always used VDPAU for
everything. Again, what everyone seems to be missing is that none of
that would explain why it uses VDPAU just fine in 29.1 (which I'm
using now) and failed in version 30, with everything (including the
playback profile) being the same.

So, have you done the git bisect to find the commit
that is impacting you?

Unfortunately given where I'm at now, that won't be possible. The
original issue I had was after updating from 29.1 to 30 and I ended up
reverting back to 29.1 (this is compiled on Gentoo by the way).
Currently I'm still on 29.1. In fact, just today I figured out how to
patch my existing 29.1 to allow me to recompile it after applying a
few fixes...so I'm probably staying on that for now. All I know is
that I had this issue in version 30 (which included some significant
changes to FFmpeg calls from 29.1).

From what I understand (based on a reply in that above bug) the
hardware acceleration FFmpeg stuff in 31 has been radically redone.
The main purpose of my original email here was to see if any others
had issues getting that sample to play with VDPAU in version 31. I
find it interesting that George above (using a GT430 as well only on a
64 bit system) had it apparently revert to software. That's the first
sign I've seen of any such issue on 64-bit.
