Hello,
I am working on a file plugin patch to allow adding PCM parameters (rate, format) to the name of the file created (plus the ability to run an external command via popen, such as upsampling with sox). I got stuck in trying to obtain these parameters in pcm_file.c:_snd_pcm_file_open(). Is it actually possible or the information is not available at the time of opening the file (and the whole patch is thus nonsense)?
Thanks a lot for help.
I am now opening the output file in pcm_file.c:snd_pcm_file_write_bytes. Surprisingly it seems to work fine. Could such hack be accepted as a patch to the plugin (if coded properly)? Is there a better place to open the file?
The file should be opened in the hw_params callback (all PCM parameters are known in this time). Also, extending filename with PCM parameters should be optional (configurable). But the idea looks nice.
JaroslavHello,
please find enclosed a patch for the file plugin. The checkpatch.pl script throws 5 bogus errors in doxygen comments.
Signed-off-by: Pavel Hofman pavel.hofman@insite.cz
- added support for including pcm stream params in the output filename
- added support for piping the stream to a shell command if the filename
string starts with a pipe char
Thanks a lot,
Pavel.
Hi,
Please let me know if there some areas to work on before the patch can be accepted for merge.
Thanks a lot,
Pavel.
