No audio and video stutters

jens_elmo · #1 (**permalink**) 06-Nov-2009, 07:30

Hi,

I am not sure if this is the right forum, but I am running on a 11.2 pre-release so I better start here.

Its a new OpenSuse 11.2 installation completely from scratch
I have followed the guidelines in the new users forum for installing restricted multimedia formats
I have used the indicated repositories in the correct 11.2 version from packman and videolan

The only relevant exception is ffmpeg where i have tried to download and compile the latest release directly from ffmpeg.org - same result

I have this problem only with a few new danish DVB-t HD channels.
The normal TV channels are OK
I am using KDE desktop and kaffeine to whatch the TV channels
The DVB-t card is a Hauppauge HVR-4000

To troubleshoot the problem I have recorded one of the HD channels with tzap
No problem - the status is constantly FE_HAS_LOCK
snr stays at ffff
(See screendump below)

mplayer wont read the resulting file.
See screendump for error messages below

However, ffplayer will open the file and the result is the same
as I see in kaffeine : no audio and video stutters incredibly

ffplayer complains a lot about:
number of reference frames exceeds max (probably corrupt input), discarding one.

Just a guess.

Looks like you are missing a codec for ADecode. Install ffmeg and codec's from packman repositories.

jens_elmo · #3 (**permalink**) 06-Nov-2009, 08:13

I did download ffmpeg from packman and enough codecs to make everything work, except for 3 HD TV channels
I am sort of a newbee because the last time I typed "make" was in 1985....
linux has come a long way since i played around with it
So I may need more specific directions than the average user

ffplayer tries to open the file so i guess it thinks it has the codec for both audio and video

Though the header for audio seems to be missing:
(from ffplayer screendump)

[mp2 @ 0x6a08b0]Header missing 0KB vq= 0KB sq= 0B

Video is identified as h264 but gives error messages too:

[h264 @ 0x69f280]number of reference frames exceeds max (probably corrupt input), discarding one
[h264 @ 0x69f280]mmco: unref short failure sq= 0B

Reference codecs, and openSUSE, here is a limited summary based on my minimal understanding based on what is available for openSUSE on the Packman packagers web site ...

Typically for codecs in openSUSE:

libffmpeg0 - installing libffpmeg0 picks up a bunch of dependencies, which is good for most use PackMan :: Package details for ffmpeg
w32codec-all provides some more exotic codecs PackMan :: Package details for w32codec-all
xvidcore - MPEG-4 ASP video codec - PackMan :: Package details for xvidcore
x264 libraries (free library for encoding next-generation H264/AVC video streams - and I confess I do not understand the difference): PackMan :: Package details for x264-75 and PackMan :: Package details for x264-72 and PackMan :: Package details for x264-67 and PackMan :: Package details for x264
libquicktime - PackMan :: Package details for libquicktime
libmpeg2 - PackMan :: Package details for libmpeg2
libmpeg3 - PackMan :: Package details for libmpeg3

where there is some duplication in the above. Plus there are some codecs I have missed.

Hi,

I missed a few of those codecs
lib264-72 and -75 X264 and libmpeg3

Still, no change after installing them with Yast and reboot

Would it be posible to upload my testvideo to see if anyone can play it correctly ?

I have seen various posts on the internet describing almost the same problems at least with the video
But no answers.
As they are the new public TV channels in Denmark, replacing the old analogue signals last Sunday, I would think there should be some general interest in Denmark
- small country though

regards

Elmo

apologies for the edit in previous post - finger trouble on my part.

You could upload your video to a site like rapidshare: RapidShare: 1-CLICK Web hosting - Easy Filehosting which allows 10 free downloads.

Hi
Tried your video with the fluendo codecs on my SLED machine, no go with
totem. Also tried here with mplayer and get the same errors.

One wonders if they are new channels that there is some new drm being
added to the stream. How are you capturing the stream in the first
instance?

I downloaded and looked briefly at the video. It only plays with ffplay on my pc, and with that it also has no audio, and the video stutters. These are the details I noted on that format:

Code:

General

Audio
ID : 	2271 (0x8DF)
Format : 	MPEG Audio
Duration : 	37s 34ms

I also noted:
ffmpeg -i testvideo.mpg
gives:

Code:

Seems stream 0 codec frame rate differs from container frame rate: 50.00 (50/1) -> 25.00 (25/1)
Input #0, mpegts, from 'testvideo.mpg':

    Stream #0.1[0x8df]: Audio: mp3, 0 channels, s16

it also gives some h264 errors.

Hi,

To capture the video, I first created a new channel.conf with scan
I could not find any channel.conf in my installation so I had to make it myself.

Then i used tzap:
tzap -f1 -r "FOLKETINGET"

Where FOLKETINGET is the name of one of the HD channels present in channel.conf

Then on another terminal:
cat /dev/dvb/adapter0/dvr0 > testvideo.mpg
