* fftools/ffmpeg: fix -t inaccurate recording timeShiwang.Xie2021-07-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | if input start time is not 0 -t is inaccurate doing stream copy, will record extra duration according to input start time. it should base on following cases: input video start time from 60s, duration is 300s, 1. stream copy: ffmpeg -ss 40 -t 60 -i in.mp4 -c copy -y out.mp4 open_input_file() will seek to 100 and set ts_offset to -100, process_input() will offset pkt->pts with ts_offset to make it 0, so when do_streamcopy() with -t, exits when ist->pts >= recording_time. 2. stream copy with -copyts: ffmpeg -ss 40 -t 60 -copyts -i in.mp4 -c copy -y out.mp4 open_input_file() will seek to 100 and set ts_offset to 0, process_input() will keep raw pkt->pts as ts_offset is 0, so when do_streamcopy() with -t, exits when ist->pts >= (recording_time+f->start_time+f->ctx->start_time). 3. stream copy with -copyts -start_at_zero: ffmpeg -ss 40 -t 60 -copyts -start_at_zero -i in.mp4 -c copy -y out.mp4 open_input_file() will seek to 120 and set ts_offset to -60 as start_to_zero option, process_input() will offset pkt->pts with input file start time, so when do_streamcopy() with -t, exits when ist->pts >= (recording_time+f->start_time). 0 60 40 60 360 |_______|_____|_______|_______________________| start -ss -t This fixes ticket #9141.

* Fix double write of DASH manifest in streaming modeKevin LaFlamme2021-07-14

* libavformat/rtsp.c: Reply to GET_PARAMETER requestsHayden Myers2021-07-12
| | | | | | | | | | | | | | Some encoders send GET_PARAMETER requests as a keep-alive mechanism. If the client doesn't reply with an OK message, the encoder will close the session. This was encountered with the impath i5110 encoder, when the RTSP Keep-Alive checkbox is enabled under streaming settings. Alternatively one may set the X-No-Keepalive: 1 header, but this is more of a workaround. It's better practice to respond to an encoder's keep-alive request, than disable the mechanism which may be manufacturer specific.

* {configure,avcodec/libx264}: remove separate x264_csp_bgr checkJan Ekström2021-07-12
| | | | | | We already require X264_BUILD >= 118, which includes an unconditional definition of X264_CSP_BGR in itself, thus making this check effectively always true.
* configure: move x264_csp_bgr check under general libx264 checksJan Ekström2021-07-12
| | | | | | | | | | | | This makes the libx264rgb check work when pkg-config is utilized and x264.h is not part of the standard include path (as is often with cross-compilation, or when you just have a custom prefix in general in f.ex. your home directory). The X264_BUILD >= 118 required by configure since 2011 should have X264_CSP_BGR defined unconditionally (it was added a few X264_BUILD updates earlier), but as 134cba728bc6f4e3c5caec98b800faad244d8cfb added this additional check, I have kept it for now.
* fate/oggvorbis: Fix tests after fixing AV_PKT_DATA_SKIP_SAMPLESGuangyu Sun2021-07-12
| | | | | | | | | | | | | | | | | | | | | | After fixing AV_PKT_DATA_SKIP_SAMPLES for reading vorbis packets from ogg, the actual decoded samples become fewer. Three fate tests are failing: fate-vorbis-20: The samples in 6.ogg are not frame aligned. 6.pcm file was generated by ffmpeg before the fix. After the fix, the decoded pcm file does not match anymore. Ideally the ref file 6.pcm should be updated but it is probably not worth it including another copy of the same file, only smaller. SIZE_TOLERANCE is added for this test case. fate-webm-dash-chapters: The original vorbis_chapter_extension_demo.ogg is transmuxed to dash-webm. The ref file webm-dash-chapters needs to be updated. fate-vorbis-encode: This exposes another bug in the vorbis encoder that initial_padding is not correctly set. It is fixed in the previous patch.

* libavcodec/vorbisenc: Add missing initial_paddingGuangyu Sun2021-07-12
| | | | | | | | | | | Vorbis has priming samples at the beginning. If the initial_padding is not set in the encoder, the total sample count will be one frame fewer than it should be. The result is that we get a truncated version of encoding. initial_padding should be set to the frame_size used in vorbis_encode_frame(). Signed-off-by: Guangyu Sun <gsun@roblox.com>
* avformat/oggparsevorbis: Update end_trimming for the last packetGuangyu Sun2021-07-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Without end_trimming, the last packet will contain unexpected samples used for padding. This commit partially fixes #6367 when the audio length is long enough. dd if=/dev/zero of=./silence.raw count=20 bs=500 oggenc --raw silence.raw --output=silence.ogg oggdec --raw --output silence.oggdec.raw silence.ogg ffmpeg -codec:a libvorbis -i silence.ogg -f s16le -codec:a pcm_s16le silence.libvorbis.ffmpeg.raw ffmpeg -i silence.ogg -f s16le -codec:a pcm_s16le silence.native.ffmpeg.raw ls -l *.raw The original test case in #6367 is still not fixed due to a remaining issue. The remaining issue is that ogg_stream->private is not kept during ogg_save()/ogg_restore(). Field final_duration in the private data is important to calculate end_trimming. Some common operations such as avformat_open_input() and avformat_find_stream_info() before reading packet will trigger ogg_save() and ogg_restore(). Luckily, final_duration will not get updated until the last ogg page. The save/restore mentioned above will not change final_duration most of the time. But if the audio length is short, those reads may be performed on the last ogg page, causing trouble keeping the correct value of final_duration. We probably need a more complicated patch to address this issue. Signed-off-by: Guangyu Sun <gsun@roblox.com>
* cafenc: fill in avg. packet size later if unknownRoman Beranek2021-07-12
| | | | | | | | | | | | | | | | | Frame size of Opus stream was previously presumed here to be 960 samples (20ms), however sizes of 120, 240, 480, 1920, and 2880 are also allowed. It can also alter on a per-packet basis and even multiple frames may be present in a single packet according to the specification, for the sake of simplicity however, let us assume that this doesn't occur. Because the mFramesPerPacket field, representing the number of samples per packet in the ffmpeg terminilogy, is the key factor in calculating packet durations and all that follows from that (index, bitrate, ...), it is crucial to get right. Therefore, if the packet size is not available ahead of time (as it is in the case of Opus), calculate an average from the stream duration once we know how many packets there are and update the filed in the header.
