Transcode OpenSuse 13.1

Martin Preiss

Hi,

can't make TVheadend use Transcode on OpenSuse 13.1.

I compiled ffmpeg, x264, faac etc... but still getting this error:

As well when trying to ./configure again from git, even that libavcodec = 55.49.101 it says fail.

Any ideas?

Dunno about OpenSuse, but 'buntu needs libavcodec-extra-53 or similar, which includes libx264 as the encoding library. There's also libx264-dev, which I think may include the same.

Martin Preiss

So I managed to solve the problem with h264. U need to use +*specific*+ ffmpeg release. In my case i used 1.2.5, the latest GIT of ffmpeg doesn't work, because it's libavcodec is higher then 55.0.0. So you need something between 52.49 and 55.0.0.0 as is requested. Unfortunately now the problem switched from h264 to AAC and i'm in same problem just with AAC. Which was working before...

tvheadend latest git 3.9~

Martin Preiss

So I made success that transcoding is working with this versions:

tvheadend: version 3.9.379~g6f1b17e-dirty
libav - 0.8.9
libavcodec 53.35.0
libavutil 51.22.1
libavformat 53.21.1

libswscale 2.1.0

with

faac

all other combinations: ffmpeg 1.2.5, ffmpeg 2.0.3, ffmpeg-latest-git, libav 9.10, fdk_aac

are not working and will not find aac encoder even it was compiled and it is in system (in ffmpeg 1.2.5 and libav 9.10 fdk_aac)
or

it will not find h264 coder even it was compiled and it is working (ffmpeg 2.0.3, ffmpeg-latest)

So it's working. But the quality of sound is horrible, it's breaking, clicky etc...

I built with a new~ish copy of ffmpeg I updated the transcode.c to use ffmpeg audio4 calls and fixed some other depreciated buffer stuff.
Packages:
openssl 1.0.1
zlib 1.2.3.4
libcurl 7.22.0
liburiparser 0.7.5
avahi-client 0.6.30
libavcodec 55.45.103
libavutil 52.58.101
libavformat 55.22.100

libswscale 2.5.101

But --

Can anyone decipher what -22 is ? from ffmpeg avcodec_decode_video2 and avcodec_decode_audio4 these are on the decode side not the encode side.

I have plex plug-in calling and it seems so close ....

Mark Kirkpatrick

Sorry, i has firware updated the hdhomerun but not fixed the libraries to match, now I have decodes , and a mux problem that i can persue.

Mark Kirkpatrick

The failed to write frame is were it's at, possibly due to AVFrame type changes that I made for audio4 support, I'll keep looking
