VLC 2.0.3 Twoflower: Audio is choppy when watching Analog TV

Postby 0xCAFE » 13 Sep 2012 20:52

Hi All,

Video is OK, but Audio is choppy when watching Analog TV with VLC on Windows 7 x64, even trying to change Audio Ouput Module to DirectX/Win32 Waveout (http://wiki.videolan.org/WindowsFAQ-2.0 ... _anomalies).

I saw another topics related to this issue and it seems that it's very frequent:
viewtopic.php?f=12&t=44843
http://www.tmsnetwork.org/blog/fixing-c ... FIjKlHpyZQ

The PCI-express TV card I'm using works sucessfully with Windows Media Center on the same computer (Desktop PC, Intel Xeon 2.8GHz, 24GB RAM!). Also, Video and Audio are OK when running with VLC+Linux.

Audio format:
  • Channels: 2;
  • Bits per Sample: 16;
  • Samples per Sec: 48000.
Please, find below the log (verbosity = 2):

I really appreciate any help on this.

Regards,
Martinez

Re: VLC 2.0.3 Twoflower: Audio is choppy when watching Analo

Postby Lotesdelere » 14 Sep 2012 09:30

You can try to:

- Disable time stretching in the audio preferences Menu Tools -> Preferences -> Audio

- Increase the file cache to 1000 or 2000 ms Menu Tools -> Preferences (Show Settings = ALL) -> Input/Codecs then scroll down to Advanced/File Caching on the right panel

- Force the number of FFmpeg threads to 4 or 2 or even 1 Menu Tools -> Preferences (Show Settings = ALL) -> Input/Codecs -> Video Codecs -> FFmpeg

- Use a faster resampler by setting the Sample Rate Converter type to Zero Holder Hold Menu Tools -> Preferences (Show Settings = ALL) -> Audio -> SRC Resampler

After the changes save the preferences then exit and restart VLC. And please be kind enough to report us what worked and what had no effect for you.

Hello,

Thanks for your tips but none of those worked for me. Before posting, I had tried some changes, such as time stretching, caching, SRC samples etc. I haven't changed FFMPEG threads.

Anyway, please find below the results for each test you mention. I've been starting VLC with the following line command:

Code: Select all

vlc dshow:// :dshow-vdev="<MyTVCardVideoDevName>" :dshow-adev="<MyTVCardAudioDevName>" :dshow-size=720x480 :dshow-aspect-ratio=4\:3 :dshow-chroma= :dshow-fps=0 :no-dshow-config :no-dshow-tuner :dshow-tuner-channel=0 :dshow-tuner-frequency=<FreqInHz> :dshow-tuner-country=0 :dshow-tuner-standard=0 :dshow-tuner-input=0 :dshow-video-input=-1 :dshow-video-output=-1 :dshow-audio-input=-1 :dshow-audio-output=-1 :dshow-amtuner-mode=1 :dshow-audio-channels=0 :dshow-audio-samplerate=0 :dshow-audio-bitspersample=0 :live-caching=300
where <MyTVCardVideoDevName> and <MyTVCardAudioDevName> are meaning video and audio devs, that have been omitted. <FreqInHz> is related to the analog TV channel.

Consider the statement "the same behavior" concerning the perception by human beings (a rough subjective criteria, but the only available here). Also consider Video OK for all tests.

- Disable time stretching in the audio preferences Menu Tools -> Preferences -> Audio
Disabled. The same behavior: Audio is still choppy.

- Increase the file cache to 1000 or 2000 ms Menu Tools -> Preferences (Show Settings = ALL) -> Input/Codecs then scroll down to Advanced/File Caching on the right panel
Changed from 500 to 2000 stepping 250. Audio stopped after 835 ms, found out by binary searching :-). I attached logs for some values:

1000 ms:

- Force the number of FFmpeg threads to 4 or 2 or even 1 Menu Tools -> Preferences (Show Settings = ALL) -> Input/Codecs -> Video Codecs -> FFmpeg.
'Threads' was defined as '0' (auto). Tried with the following values: 16, 8, 4, 2, 1. The same behavior: Audio is choppy.

- Use a faster resampler by setting the Sample Rate Converter type to Zero Holder Hold Menu Tools -> Preferences (Show Settings = ALL) -> Audio -> SRC Resampler.
Changed to ' Zero Holder Hold' as suggested, also to ' Linear'. The same behavior: Audio is choppy.

After the changes save the preferences then exit and restart VLC.
After each change, saved and (re)started.

No effect so far. Do you have a clue?

Regards,
Martinez

Does it work better if you downgrade to VLC 1.1.11 ?

Same behavior, even increasing caching to 1000/2000 ms. Please find below the messages considering VLC 1.1.11 The Luggage.
Also tried to change Audio output module (DirectX audio output and Win32 waveOut extension output).

VLC command:

Code: Select all

Re: VLC 2.0.3 Twoflower: Audio is choppy when watching Analo

Postby 0xCAFE » 17 Sep 2012 19:47

On Linux:

By compiling VLC 1.1.13 source code, Audio works perfectly for analog TV.
By compiling VLC 2.0.3 source code, Audio remains choppy.

Is there a reason for this issue in newer VLC version?

Try to deactivate libsamplerate and libspeex_dsp plugins.

No changes. Audio remains choppy:

It seems that there is no easy solution for this issue. Perhaps I should consider a downgrade to previuos VLC versions.
Does anyone know whether there is an issue reported to the official bug tracker concerning choppy audio?

ALSA input may be quite broken in VLC 2.0. Try VLC 2.1.

Hi Rémi,
Nice to know that. Thanks for replying.
Do you recommend a specific git branch/tag for 2.1 from http://git.videolan.org?
AFAIK, there is no official release for VLC 2.1. It would be helpful to get some (as much as possible) stable version for building.

Regards,
Martinez

I can confirm that i was having almost the same problem and the vlc-2.1.0-20130116-0014.tar.xz snapshot fixed the audio problem. But the video was nowhere to be seen exactly with the same configuration.
