No sound playing avi with 2 audio streams

[Stilgar]

Hi,

I found a possible bug in the new versions (at least in 1.70.1 and 1.60.0), in the version 1.54.0 it works fine.
Using the engine MEncoder, AVI files with two audio streams are reproduced without any sound.
If I remove one of the audio streams it works fine.
By the way, the MKV files with two audio streams also work fine.

This issue seems no related with the audio format. I have tested with these audio combinations (1st stream/2nd stream): AC3/AC3; AC3/mp3; mp3/AC3

The problem seems to be that the audio stream ID is incorrectly identified. It uses the 0 id instead of the "1" id:

But in the version 1.54.0 it is been used the correct one:

As a workaround I could use a custom parameter like this:
container == avi :: -aid 1
With this parameter the first audio stream is always reproduced, but the second one cannot be selected anymore.

I think I will come back to the version 1.54.0 which seems to work fine in my case.

Other data:
-Windows 7 x64 SP1
-Java 1.7.0_09
-AMD Phenom 9850 Quad-Core Processor 2.50 GHz
-RAM 4 GB
-Renderer: Sony Bravia EX
-Wifi connection

Greetings.

Thanks for sharing the analysis. It looks like the effect might be related to this piece of TODO code in MEncoderVideo.java, line 2359:

Code: Select all

            String aid = null;
            if (media != null && media.getAudioTracksList().size() > 1 && params.aid != null) {
               if (media.getContainer() != null && (media.getContainer().equals(FormatConfiguration.AVI) || media.getContainer().equals(FormatConfiguration.FLV))) {
                  // TODO confirm (MP4s, OGMs and MOVs already tested: first aid is 0; AVIs: first aid is 1)
                  // for AVIs, FLVs ans MOVs mencoder starts audio tracks numbering from 1
                  aid = "" + (params.aid.getId() + 1);
               } else {
                  // everything else from 0
                  aid = "" + params.aid.getId();
               }
            }

Hi,
Now I'm using the version 1.54.0 with any problem, so it's OK for me.
