Can VLC play m2ts with LPCM audio

[kkbee19]

Hi
I play a m2ts file.The file have only LPCM audio.
When VLC open it, VLC change state to stop automatically.
Thanks.

Please open Tools -> Messages (set Verbosity to 2) before you start the playback and then paste the full resulting log here or on Pastebin if it's too long.
Also upload a SHORT sample of a problematic file to Multiupload.com, so it will upload the file for you to several other hosts, and then post the link to the file here.

Yes, VLC can play LPCM-

[kkbee19]

1.Why I can't play mpeg2-ts file which olny have LPCM audio
I converte this mpeg2-ts by a software using pcm alaw.
2.Can I use ffmpeg to converter ac-3 to LPCM in mp2ts
3.Is pcm alaw the same as LPCM?
I can play mpeg2-ts file which olny have AC-3 audio
I think " ts debug: * es pid=256 type=6 *unknown* ", this maybe the question.

I trace code and I found that pid->es->fmt.i_cat == UNKNOWN_ES and it will go into
if( pid->es->fmt.i_cat == UNKNOWN_ES )
{
msg_Dbg( p_demux, " * es pid=%d type=%d *unknown*",
p_es->i_pid, p_es->i_type );
}
Is there are some errors in my ts file?
ps:VLC can play mp2-ts file which only have video.




Thanks.

As requested before, upload a short sample of a problematic file to either http://streams.videolan.org/upload/ or to Multiupload.com, so it will upload the file for you to several other hosts, and then post the link to the file here.
