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. |
