axfer: add an entry point for this command This commit adds a new command, 'axfer' ('ALSA transfer'), to transfer data frames described in asound.h. This command is intended to replace current aplay. The most of features and command line parameters come from aplay as much as possible, while it has more better feature and code to maintain. This commit adds an entry point for this command. Current option system of aplay is still available, while this command has a sub-command system like commands in iproute2. Currently, two sub-commands are supported; 'list' and 'transfer'. The 'list' sub-command has the same effect as '-l' and '-L' options of aplay. The 'transfer' sub-command has the same effect as the main feature of aplay. For the sub-command system, an option for stream direction is required; '-P' for playback and '-C' for capture. If you create symbolic links to this binary for aplay/arecord, please execute: $ ln -s axfer aplay $ ln -s axfer arecord Actual code for each sub-command will be implemented in later commits.

axfer: add a common interface to handle a file with audio-specific data format Current aplay supports several types of data format for file; Microsoft/IBM RIFF/Wave (.wav), Sparc AU (.au) and Creative Tech. voice (.voc). These formats were designed to handle audio-related data with interleaved frame alignment. This commit adds a common interface to handle the file format, named as 'container' module. This includes several functions to build/parse the format data from any file descriptors. Furthermore, this includes several helper functions for implementations of each builder/parser.

axfer: add a sub-command to print list of PCMs/devices Original aplay implementation has a feature to output two types of list; devices and PCMs. The list of devices is a result to query sound card and pcm component structured maintained in kernel land. The list of PCMs is a result to parse runtime configuration files in alsa-lib. Entries in the former list is corresponding to ALSA PCM character device ('/dev/snd/pcm%uC%uD[p\|c]'), while entries in the latter list includes some 'virtual' instances in application runtime. This commit adds an implementation for the above functionality. This is executed by taking 'list' sub-command. A 'device' option has the same effect as '--list-devices' and '-L' of aplay. A 'pcm' option has the same effect as '--list-pcms' and '-l' of aplay. In both cases, an additional option is required for stream direction. Below is examples of new command system for this sub-command. $ axfer list device -C (= arecord --list-devices) $ axfer list pcm -P (= aplay -l) Signed-off-by: Takashi Sakamoto <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de> 2018-11-13 07:41:14 +01:00			`main.c \`
