m2ts files stream with no audio

Post by ajkessel » Fri Jun 19, 2020 8:55 am

I have several m2ts files that show up as having no audio at all on a variety of renderers (e.g., VLC, PS3).

A couple of examples - ffmpeg reports:

Code: Select all

Program 1
    Metadata:
      service_name    : Service01
      service_provider: FFmpeg
    Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc
    Stream #0:1[0x101]: Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, 5.1(side), fltp, 640 kb/s
Another example:

Code: Select all

Program 1
    Metadata:
      service_name    : Service01
      service_provider: FFmpeg
    Stream #0:0[0x100]: Video: h264 (High) ([27][0][0][0] / 0x001B), yuv420p(progressive), 1920x1080 [SAR 1:1 DAR 16:9], 23.98 fps, 23.98 tbr, 90k tbn, 47.95 tbc
    Stream #0:1[0x101]: Audio: dts (DTS-HD MA) ([130][0][0][0] / 0x0082), 48000 Hz, 5.1(side), s32p (24 bit)
UMS trace (for the second example) and conf file attached.

If I convert the file to a MKV container with no transcoding (ffmpeg -i input.m2ts -map 0 -c copy output.mkv) the audio stream appears on all renderers. I could convert everything to MKV, but shouldn't it work on m2ts? Also, if I convert to MKV, it will no longer stream to the PS3, only transcode.

Full log attached -- NOAUDIO is the file which is streaming video only, and AUDIOWORKS is a file containing the same two streams, repackaged as an MKV.

Hello, I have the same problem with trying to play m2ts files - it has around 13 or more audio tracks and I only need 1, but of the transcode folder, only 3 or 4 files actually have audio playing, but none of them is the one I want.
I use VLC for Android on a Blaupunkt 4k 55" Android 6.0 TV as renderer. On my PC, VLC for Win plays the same m2ts with no issues and sees all 13+ audio tracks.
