Hi Thomas, 

The patch is a tiny bit different for VDR 2.2.0 - in remux.c - see below 

There's a small issue with audio types also: 
Here, AAC (ADTS) per ISO/IEC 13818-7 or AAC (LATM) per ISO/IEC 14496-3 is regularly used for audio in HD broadcasts 
- my suggestion is that these streams should be handled too. 
For example, I transcode radio/audio to AAC in m4a or AAC_LATM in .ts files. 
Arguably the newer ATSC, DTS, Dolby true HD... streams should be added too 
( https://en.wikipedia.org/wiki/Program-specific_information#Elementary_stream_types ) 

For now my audioparser line looks like this, which works for both flavours of AAC, and they play on Kodi and VLC. 
else if (type == 0x03 || type == 0x04 || type == 0x06 || type == 0x0F || type == 0x11) // MPEG2,4 AAC, AC3 audio 

The original audio-only .ts (MP2 codec) actually doesn't play in VLC, but plays in ffplay. 

Patch:

Hi Richard 

I observed the same behavior two weeks ago when I wanted to replay an edited radio recording. Please find my proposed fix attached, maybe Klaus will take it into the next VDR developer release. 

Regards, 
Thomas
