|

Using the parsed information upstream, and the list of allowed caps downstream, this code
|

tries to find a suitable audio info. It is important to keep in mind that the rate and number of channels
|
||||
should never deviate from the one the bitstream has, otherwise mpg123 has to mix channels and/or
|
||||
resample (and as its docs say, its internal resampler is very crude). The sample format, however,
|
||||
can be chosen freely, because the MPEG specs do not mandate any special format.
|
||||
Therefore, rate and number of channels are taken from upstream (which parsed the MPEG frames, so
|
||||
the incoming_caps contain exactly the rate and number of channels the bitstream actually has), while
|
||||
the sample format is chosen by trying out all caps that are allowed by downstream. This way, the output
|
||||
is adjusted to what the downstream prefers.
|
||||
|
||||
Also, the new output audio info is not set immediately. Instead, it is considered the "next audioinfo".
|
||||
The code waits for mpg123 to notice the new format (= when mpg123_decode_frame() returns MPG123_AUDIO_DEC_NEW_FORMAT),

and then sets the next audioinfo. Otherwise, the next audioinfo is set too soon, which may cause problems with
|
||||
mp3s containing several format headers. One example would be an mp3 with the first 30 seconds using 44.1 kHz,
|
||||
then the next 30 seconds using 32 kHz. Rare, but possible.
|
||||
|
||||
STEPS:
|
||||
|
||||
1. get rate and channels from incoming_caps
|
||||
2. get allowed caps from src pad
|
||||
3. for each structure in allowed caps:
|
||||
3.1. take format
|
||||
3.2. if the combination of format with rate and channels is unsupported by mpg123, go to (3),
|
||||
or exit with error if there are no more structures to try
|
||||
3.3. create next audioinfo out of rate,channels,format, and exit

/* Using the parsed information upstream, and the list of allowed caps
|
||||
* downstream, this code tries to find a suitable audio info. It is important
|
||||
* to keep in mind that the rate and number of channels should never deviate
|
||||
* from the one the bitstream has, otherwise mpg123 has to mix channels and/or
|
||||
* resample (and as its docs say, its internal resampler is very crude). The
|
||||
* sample format, however, can be chosen freely, because the MPEG specs do not
|
||||
* mandate any special format. Therefore, rate and number of channels are taken
|
||||
* from upstream (which parsed the MPEG frames, so the input_caps contain
|
||||
* exactly the rate and number of channels the bitstream actually has), while
|
||||
* the sample format is chosen by trying out all caps that are allowed by
|
||||
* downstream. This way, the output is adjusted to what the downstream prefers.
|
||||
*
|
||||
* Also, the new output audio info is not set immediately. Instead, it is
|
||||
* considered the "next audioinfo". The code waits for mpg123 to notice the new
|
||||
* format (= when mpg123_decode_frame() returns MPG123_AUDIO_DEC_NEW_FORMAT),
|
||||
* and then sets the next audioinfo. Otherwise, the next audioinfo is set too
|
||||
* soon, which may cause problems with mp3s containing several format headers.
|
||||
* One example would be an mp3 with the first 30 seconds using 44.1 kHz, then
