* fftools/ffmpeg: use av_packet_alloc() to allocate packetsJames Almer2021-03-17

* fftools: Switch to const AVCodec * where possibleAndreas Rheinhardt2021-03-02
| | | | | | | | | | | The obstacle to do so was in filter_codec_opts: It uses searches the AVCodec for options via the AV_OPT_SEARCH_FAKE_OBJ method, which requires using a void * that points to a pointer to a const AVClass. When using const AVCodec *, one can not simply use a pointer that points to the AVCodec's pointer to its AVClass, as said pointer is const, too. This is fixed by using a temporary pointer to the AVClass. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* ffmpeg: add option stats_periodGyan Doshi2020-12-23
| | | | | | | | | At present, progress stats are updated at a hardcoded interval of half a second. For long processes, this can lead to bloated logs and progress reports. Users can now set a custom period using option -stats_period Default is kept at 0.5 seconds.
* ffmpeg: add a data size threshold for muxing queue sizeJan Ekström2020-10-29
| | | | | | | | | | | | | | | | | | | | | | | | | This way the old max queue size limit based behavior for streams where each individual packet is large is kept, while for smaller streams more packets can be buffered (current default is at 50 megabytes per stream). For some explanation, by default ffmpeg copies packets from before the appointed seek point/start time and puts them into the local muxing queue. Before, it getting utilized was much less likely since as soon as the filter chain was initialized, the encoder (and thus output stream) was also initialized. Now, since we will be pushing the encoder initialization to when the first AVFrame is decoded and filtered - which only happens after the exact seek point is hit as packets are ignored until then - this queue will be seeing much more usage. In more layman's terms, this attempts to fix cases such as where: - seek point ends up being 5 seconds before requested time. - audio is set to copy, and thus immediately begins filling the muxing queue. - video is being encoded, and thus all received packets are skipped until the requested time is hit.

* fftools/ffmpeg_filter: add -autoscale to disable/enable the default scaleLinjie Fu2020-06-18
| | | | | | | | | | | | | | | | | | | | | Currently, ffmpeg inserts scale filter by default in the filter graph to force the whole decoded stream to scale into the same size with the first frame. It's not quite make sense in resolution changing cases if user wants the rawvideo without any scale. Using autoscale/noautoscale as an output option to indicate whether auto inserting the scale filter in the filter graph: -noautoscale or -autoscale 0: disable the default auto scale filter inserting. ffmpeg -y -i input.mp4 out1.yuv -noautoscale out2.yuv -autoscale 0 out3.yuv Update docs.

* fftools/ffmpeg: fix for all forced key frames when 'copyts' is enabledVishwanath Dixit2018-06-04
| | | | | | | | | | Forced key frames generation functionality was assuming the first PTS value as zero, but, when 'copyts' is enabled, the first PTS can be any big number. This was eventually forcing all the frames as key frames. To resolve this issue, update has been made to use first input pts as reference pts.

* ffmpeg: remove dead call to av_parser_change()James Almer2018-03-23
| | | | | | | | | | | It's been a noop for years, and it's been argued that in-band headers should not be forcedly removed without the user's explicit request. Also, as the FIXME line stated, this is a job for a bitstream filter like extract_extradata, remove_extradata, dump_extradata, and filter_units. Signed-off-by: James Almer <jamrial@gmail.com>
