* Add option to output X-PAD in intervals onlyStefan Pöschel2019-02-121-5/+22
| | | | Also hide PADPacketizer::GetPAD().
* Use range-based for loop where possibleStefan Pöschel2018-12-081-2/+2

* DLS: add support to request DLS file re-readStefan Pöschel2018-11-111-0/+17
| | | | | | | | | | | A re-read of any of the used DLS files can now be requested by storing a file with the same filename which is suffixed by `.REQUEST_DLS_REREAD`. When the next PAD is going to be encoded and such a file is present, the encoder changes the current DLS file to the related DLS file, if needed (only applies if multiple DLS files are used). The DLS file is re-read and the request file is deleted. The DLS is also immediately inserted into the PAD transmission.
* Separate re-read file checkStefan Pöschel2018-11-111-14/+24

* SLS: add option to limit slide sizeStefan Pöschel2018-03-041-49/+61

* SLS: add support to request slides dir re-readStefan Pöschel2018-02-161-2/+20
| | | | | | | A re-read of the slides dir can now be requested by storing a file named `REQUEST_SLIDES_DIR_REREAD` into the slides dir. When the next slide is going to be encoded and this file is present, the slides dir is re-read and this file is deleted.
* SLS: skip to next working slide on problemStefan Pöschel2018-02-151-15/+30
| | | | | | | When a slide cannot be encoded, skip to the next slide that works. To prevent an infinite loop, no skipping is done when the last slide of the slide store doesn't work and also no earlier slide of it worked.

* Add uniform PAD encoderStefan Pöschel2017-08-241-6/+111
| | | | | | | | | | | | | | | | | | | | | | | | | | | The uniform PAD encoder encodes every PAD on demand and is kind of synchronized to the audio encoder by means of the frame duration. Insertion intervals for slides and labels can be set indepentent from each other. It is also possible to specify how often the label is inserted. If the slides interval "0" is used, the next slide is inserted just after the previous one has been transmitted. This is useful e.g. for stations that transmit just a logo slide. An initial burst count can be set to ensure that an audio encoder has enough PADs available e.g. in case the audio encoder encodes DAB+ Superframes at once and hence needs all related PADs. If a slide/label is still in transmission when the transmission of the next one is scheduled, the new transmission is skipped and a warning is shown. In this case it makes sense to increase the PAD length or to instead decrease the slide size or label insertion interval (`-L`). This new PAD encoder does not require any changes on the audio encoder side. Only in case of MP2, a recent revision of ODR-AudioEnc has to be used (commit ce25f2c or later), as it fixes a problem with PADs that solely consist of the F-PAD.

* Move current PAD encoder algorithm into subclassStefan Pöschel2017-08-231-20/+28
| | | | | This allows to replace the current PAD encoding algorithm by alternative methods in the future.

| | | | Also update website URL to HTTPS
* Move break handler modificationStefan Pöschel2017-04-301-14/+14
| | | | | Move them right before the loop, as before a break (e.g. while waiting for the audio decoder opening the pipe) didn't lead to termination.
* Add recovery on broken pipeStefan Pöschel2017-04-071-0/+4
| | | | | | | | | When the opposite side of the PAD FIFO disconnects (e.g. due to crash of the audio encoder), ODR-PadEnc crashed as well due to SIGPIPE. This commit changes the behaviour. From now on instead error messages are displayed and it is possible for a new instance of the audio encoder to reconnect to the still running ODR-PadEnc instance.
* Add cleanup before terminationStefan Pöschel2017-03-101-2/+32
| | | | | Add signal handler for SIGINT and SIGTERM that closes the output socket and deinits ImageMagick (if used).
* SLS: output ImageMagick version in verbose modeStefan Pöschel2017-03-101-0/+2
|
* Fix printf format warningStefan Pöschel2017-03-091-1/+1

* Hide/Move constantsStefan Pöschel2017-02-151-5/+4
|
* Fix sleep delay to include encoding timeStefan Pöschel2017-02-151-1/+6
| | | | | | | | Up to now the delay between two loop runs was slightly higher than the specified sleep delay as the sleeping process did not consider the time the PAD encoding needs but rather sleeped for the set sleep delay. This is now fixed by using a steady clock.
* Fix alphabetic slide sortingStefan Pöschel2017-02-151-23/+28
| | | | | | | The alphabetic sorting within the slide dir was ignored so far. Now the sorting is considered while adding slides for transmission. Furthermore now also files starting with "." are added (except the ./.. dirs).

* PAD: limit packetizer visibilityStefan Pöschel2017-02-061-29/+24
|
* PAD: insert DLS regularly while SLS transmissionStefan Pöschel2017-02-061-13/+23
| | | | | | | | | | | | | | | When a slide is transmitted, now every 50 PADs the current DLS is inserted (and thereby reread from file). Hence in the best case (AAC-LC @ 48 kHz), DLS is inserted every 1000ms; in the worst case (HE-AAC @ 32 kHz) it is inserted every 3000ms. This way a listener will get DLS much earlier after switching to a service, compared to the previous situation where the slide transmission was not interrupted for DLS insertion. Note that there still remains a delay without any PAD, between the end of a slide transmission and the start of the next one's transmission. Also note that adding a feedback channel from the audio encoder to ODR-PadEnc will make this improvement obsolete.
