Audio and video module

[danversj]

Hi CrapulaX, nice work on this feature. I just got it working under Windows 7 with VLC v1.1.9. It was a bit tricky though.

Here's what I had to enable:
Preferences:Show settings:All
Audio/Filters > Enable "Audio part of the BarGraph function"
Audio/Filters/audiobargraph > used defaults, although I changed "Sends the barGraph information every n audio packets" to 1 to enable see a more accurate display
Interface/Main interfaces > Enabled "Remote control interface"
Interface/Main interfaces/RC > Enabled "Do not open a DOS command box interface"
Video/Subtitles-OSD > Enabled "Audio Bar Graph Video sub filter"
Video/Subtitles-OSD/Audio Bar Graph > Set the following settings:
\ "Value of the audio channels levels" = 0 (setting this to 0:1 crashed VLC)
\ "X coordinate" = 0
\ "Y coordinate" = 0 (this doesn't seem to affect anything)
\ "Transparency of the bargraph" = 128 for 50% transparency which looks ok
\ "Bargraph position" = Left (seems to only work Left,Center,Right - can't go top or bottom)
\ "Alarm" = 1
\ "Bar width in pixel" = 10 (20 if I want it to be really visible

To get it to work, I have to start VLC with the added command-line switch:
"C:\Program Files\VideoLAN\VLC\vlc.exe" --rc-host localhost:12345
I have added this switch to the "Target:" field my VLC shortcut

BUGS
If "Value of the audio channels levels" = 0:1, VLC crashes (probably because my audio doesn't have extra tracks - even so, it shouldn't crash)
If I play a .mov or .mxf file encoded with IMX-D10 (Bitrate: 50 Mbit/s), the audio bar graph does not show at all.
I cannot set the vertical size of the bar graph, or move it up and down. It is the full height of the window and i can't change it.
The bar graph audio display seems to be about 0.5 seconds in advance of the video and sound that is seen and heard. That is: sounds show up on the bar graph about 1/2 a second before they are heard. It would be nice to set the synchronisiation.

REQUESTS
I'd like to be able to control which audio tracks are displayed - if the stream or file has 2 x stereo audio tracks, or 4 mono tracks, I'd like to be able to view them all.
I'd like to be able to calibrate the bar graph, and see the scale measured in dB.

Could you document this on our wiki, please?

Mono input?

If I play a .mov or .mxf file encoded with IMX-D10 (Bitrate: 50 Mbit/s), the audio bar graph does not show at all.

Please share logs, but this is probably a blending issue on an impossible format.

I cannot set the vertical size of the bar graph, or move it up and down. It is the full height of the window and i can't change it.

Misfeature more than a bug...

The bar graph audio display seems to be about 0.5 seconds in advance of the video and sound that is seen and heard. That is: sounds show up on the bar graph about 1/2 a second before they are heard. It would be nice to set the synchronisiation.

This is annoying...

BUGS
If "Value of the audio channels levels" = 0:1, VLC crashes (probably because my audio doesn't have extra tracks - even so, it shouldn't crash)

Mono input?

Audio (Stream 1 only) is a stereo MPEG Audio layer 1/2/3 (mpga) - both bars display if I specify "0". The thing is, it shouldn't crash even if I specify 0:1 and it's only stereo.

If I play a .mov or .mxf file encoded with IMX-D10 (Bitrate: 50 Mbit/s), the audio bar graph does not show at all.

Please share logs, but this is probably a blending issue on an impossible format.

When the bargraph is working, these are the messages:

See the message "main error: blending YUVA to I422 failed" - looks like blending is the issue.

I cannot set the vertical size of the bar graph, or move it up and down. It is the full height of the window and i can't change it.

Misfeature more than a bug...

OK. In the earlier screenshots posted the bars were about 1/4 the height of the video.

The bar graph audio display seems to be about 0.5 seconds in advance of the video and sound that is seen and heard. That is: sounds show up on the bar graph about 1/2 a second before they are heard. It would be nice to set the synchronisiation.

This is annoying...

Yes, understandable given how the overlay works, but would be nice to be able to delay the audio data being sent to the overlay filter.

Hello,
I would like to use same plugin with bars in my vlc. What should I do?
For me important thing is normalization in playing materials then I would like all bars set to nominal level. Are this bar is set to any level?

I modified audiobargraph_v.c to display the bars in dBFS according to IEC 268-18 standard. If anyone is interested, I can send the file.


The only small problem is a kind of delay between the bar and the audio.
Does anyone know an option more direct and with least delay that rc to pass data between the audio and video filter?

Please send the patch.

[calanor]

For a few days the patch is already available in the latest version of git.

But audiobargraph_v module no longer works because "call_object_command" has been removed from cli.lua, (and also "object commands" from oldRc) and is required for communicate audiobargraph_a module with audiobargraph_v module via rc.

http://git.videolan.org/?p=vlc.git;a=co ... ab925a937c
http://git.videolan.org/?p=vlc.git;a=co ... 1ffb700d4e

[Jean-Baptiste Kempf]

What do you mean? audiobargraph_a and audiobargraph_v should discuss without RC.

[ywlke]

Any update?

[Jean-Baptiste Kempf]

This audiobargraph is fixed in 2.2.0

[calanor]

Fantastic. But now, BarGraphCallback (audiobargraph_v.c) no longer responds to RC commands and some params can not be changed on the fly.
It could remove everything callbacks except "audiobargraph_v-alarm" and "audiobargraph_v-i_values​​" or add this commands in lua RC .

[Jean-Baptiste Kempf]

Why do you want to modify on the fly?
