splitmux: Implement new elements for splitting files at mux level. Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

* By default, it uses mp4mux and filesink, but they can be changed via
* the 'muxer' and 'sink' properties.
*
* The minimum file size is 1 GOP, however - so limits may be overrun if the

* If a video stream is available, the splitting process is driven by the video
* stream contents, and the video stream must contain closed GOPs for the output
* file parts to be played individually correctly. In the absence of a video
* stream, the first available stream is used as reference for synchronization.

splitmux: Implement new elements for splitting files at mux level. Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

splitmux: Rewrite buffer collection and scheduling Majorly change the way that splitmuxsink collects incoming data and sends it to the output, so that it makes all decisions about when / where to split files on the input side. Use separate queues for each stream, so they can be grown individually and kept as small as possible. This removes raciness I observed where sometimes some data would end up put in a different output file over multiple runs with the same input. Also fixes hangs with input queues getting full and causing muxing to stall out.

To make it work, opening of files and setting filenames is now deferred until there is some data to write to it, which also requires some changes to how async state changes and gap events are handled.

splitmuxsink: Fix occasional deadlock when ending file with subtitle Deadlock occurs when splitting files if one stream received no buffer during the first GOP of the next file. That can happen in that scenario for example: 1) The first GOP of video is collected, it has a duration of 10s. max_in_running_time is set to 10s. 2) Other streams catchup and we receive the first subtitle buffer at ts=0 and has a duration of 1min. 3) We receive the 2nd subtitle buffer with a ts=1min. in_running_time is set to 1min. That buffer is blocked in handle_mq_input() because max_in_running_time is still 10s. 4) Since all in_running_time are now > 10s, max_out_running_time is now set to 10s. That first GOP gets recorded into the file. The muxer pop buffers out of the mq, when it tries to pop a 2nd subtitle buffer it blocks because the GstDataQueue is empty. 5) A 2nd GOP of video is collected and has a duration of 10s as well. max_in_running_time is now 20s. Since subtitle's in_running_time is already 1min, that GOP is already complete. 6) But let's say we overran the max file size, we thus set state to SPLITMUX_STATE_ENDING_FILE now. As soon as a buffer with ts > 10s (end of previous GOP) arrives in handle_mq_output(), EOS event is sent downstream instead. But since the subtitle queue is empty, that's never going to happen. Pipeline is now deadlocked. To fix this situation we have to: - Send a dummy event through the queue to wakeup output thread. - Update out_running_time to at least max_out_running_time so it sends EOS. - Respect time order, so we set out_running_tim=max_in_running_time because that's bigger than previous buffer and smaller than next. https://bugzilla.gnome.org/show_bug.cgi?id=763711

Revert "splitmuxsink: Use GstBin async-handling instead of our own." This reverts commit fa008f271a52f82dededc28bd81b020ca7939b47. async-handling in GstBin causes the pipeline to spin at 100% CPU as the top-level pipeline tries to change that state to PLAYING constantly. This is a workaround for a core problem, essentially, but an improvement in this case for now.

Use separate queues for each stream, so they can be grown individually and kept as small as possible. This removes raciness I observed where sometimes some data would end up put in a different output file over multiple runs with the same input. Also fixes hangs with input queues getting full and causing muxing to stall out.

Revert "splitmuxsink: Use GstBin async-handling instead of our own." This reverts commit fa008f271a52f82dededc28bd81b020ca7939b47. async-handling in GstBin causes the pipeline to spin at 100% CPU as the top-level pipeline tries to change that state to PLAYING constantly. This is a workaround for a core problem, essentially, but an improvement in this case for now.

splitmuxsink: Add format-location-full signal Add a new signal for formatting the filename, which receives a GstSample containing the first buffer from the reference stream that will be muxed into that file. Useful for creating filenames that are based on the running time or other attributes of the buffer. To make it work, opening of files and setting filenames is now deferred until there is some data to write to it, which also requires some changes to how async state changes and gap events are handled.

splitmux: Implement new elements for splitting files at mux level.

New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

splitmux: Implement new elements for splitting files at mux level. Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

splitmux: Rewrite buffer collection and scheduling Majorly change the way that splitmuxsink collects incoming data and sends it to the output, so that it makes all decisions about when / where to split files on the input side. Use separate queues for each stream, so they can be grown individually and kept as small as possible. This removes raciness I observed where sometimes some data would end up put in a different output file over multiple runs with the same input. Also fixes hangs with input queues getting full and causing muxing to stall out.

splitmuxsink: prevent deadlock when states change too fast If the GOP is completed, pads have to start gathering for the next one but it is possible that the the state might go to COLLECTING_GOP_START and back to WAITING_GOP_COMPLETE before the thread has a chance to wake up and proceed, leaving it trapped in the check_completed_gop loop and deadlocking the other threads waiting for it to advance. To solve it, this patch also checks that tha input running time hasn't changed to prevent this scenario.

splitmuxsink: initialize mux_start_time properly mux_start_time refers to the running_time of the buffer that goes first in the output file. Normally this time is 0, so this variable is initialized to 0 during the state change to PAUSED. However, when dealing with dynamic pipelines and starting a recording while the pipeline has already run for a while, the running_time of the first buffer is > 0 and this causes a problem with detecting the end of the first file(s) when splitting by duration, because the code will later compare the threshold_time with (last buffer running_time - mux_start_time) and will get it wrong until mux_start_time advances enough to make this difference < threshold_time, creating empty files in the meantime. https://bugzilla.gnome.org/show_bug.cgi?id=753624

splitmuxsink: Fix occasional deadlock when ending file with subtitle Deadlock occurs when splitting files if one stream received no buffer during the first GOP of the next file. That can happen in that scenario for example: 1) The first GOP of video is collected, it has a duration of 10s. max_in_running_time is set to 10s. 2) Other streams catchup and we receive the first subtitle buffer at ts=0 and has a duration of 1min. 3) We receive the 2nd subtitle buffer with a ts=1min. in_running_time is set to 1min. That buffer is blocked in handle_mq_input() because max_in_running_time is still 10s. 4) Since all in_running_time are now > 10s, max_out_running_time is now set to 10s. That first GOP gets recorded into the file. The muxer pop buffers out of the mq, when it tries to pop a 2nd subtitle buffer it blocks because the GstDataQueue is empty. 5) A 2nd GOP of video is collected and has a duration of 10s as well. max_in_running_time is now 20s. Since subtitle's in_running_time is already 1min, that GOP is already complete. 6) But let's say we overran the max file size, we thus set state to SPLITMUX_STATE_ENDING_FILE now. As soon as a buffer with ts > 10s (end of previous GOP) arrives in handle_mq_output(), EOS event is sent downstream instead. But since the subtitle queue is empty, that's never going to happen. Pipeline is now deadlocked. To fix this situation we have to: - Send a dummy event through the queue to wakeup output thread. - Update out_running_time to at least max_out_running_time so it sends EOS. - Respect time order, so we set out_running_tim=max_in_running_time because that's bigger than previous buffer and smaller than next. https://bugzilla.gnome.org/show_bug.cgi?id=763711

splitmux: Implement new elements for splitting files at mux level. Implement 2 new elements - splitmuxsink and splitmuxsrc. splitmuxsink is a bin which wraps a muxer and takes 1 video stream, plus audio/subtitle streams, and starts a new file whenever necessary to avoid overrunning a threshold of either bytes or time. New files are started at a keyframe, and corresponding audio and subtitle streams are split at packet boundaries to match video GOP timestamps. splitmuxsrc is a corresponding source element which handles the splitmux:// URL and plays back all component files, reconstructing the original elementary streams as it goes.

splitmuxsink: do not destroy the multiqueue & muxer when going to NULL Instead, delay it until all request pads have been released. This is because the release_pad() vfunc requires the multiqueue and muxer to be there in order to release their request pads as well. If those elements are destroyed earlier, release_pad() does not work, no pads are released and some resources are leaked. https://bugzilla.gnome.org/show_bug.cgi?id=753622

splitmuxsink: Add format-location-full signal Add a new signal for formatting the filename, which receives a GstSample containing the first buffer from the reference stream that will be muxed into that file. Useful for creating filenames that are based on the running time or other attributes of the buffer. To make it work, opening of files and setting filenames is now deferred until there is some data to write to it, which also requires some changes to how async state changes and gap events are handled.

splitmux: Rewrite buffer collection and scheduling Majorly change the way that splitmuxsink collects incoming data and sends it to the output, so that it makes all decisions about when / where to split files on the input side. Use separate queues for each stream, so they can be grown individually and kept as small as possible. This removes raciness I observed where sometimes some data would end up put in a different output file over multiple runs with the same input. Also fixes hangs with input queues getting full and causing muxing to stall out.
