Michael Niedermayer	1a7af514de	ffmpeg: move decoded_frame->pts computation together This clarifies the code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	c76a5365bb	ffmpeg: Fix rounding errors in decoded_frame->pts computation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	9b1fdb1c5a	ffmpeg: fix assumed decoded_frame->pts timebase Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	b616405c16	ffmpeg: reset decoded_frame->pts after rescaling. This ensures its not used afterwards. This commit should not change anything as it should not have been used afterwards. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	55fa883b30	ffmpeg: fix units of next_?ts in debug printing routine. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Nicolas George	6bf87785e8	ffmpeg: warn about new streams after startup.	12 years ago
Nicolas George	3ccf22c64a	ffmpeg: keep packet/frame availability in global structures. This replaces the use of the no_packet and no_frame arrays.	12 years ago
Nicolas George	1cadab6023	ffmpeg: select input file based on output time. Filters can change the timings, so input files must not necessarily be read at the same rythm. This patch select the input file to read based on the timestamp at output instead of input. With complex filter graphs, finding the input for a given output is done by making a request and checking to what buffer source it has been forwarded.	12 years ago
Nicolas George	bf8ce5a5c3	ffmpeg: probe buffersinks once more after EOF. Reap buffers stored in the buffer sinks even when the avfilter_graph_request_oldest() loop only returns EOF. avfilter_graph_request_oldest() can cause frames to arrive to the sinks even when it returns EOF.	13 years ago
Nicolas George	d853ed46b1	Revert "ffmpeg: set pkt_timebase" This reverts commit `744bd8d08c`. pkt_timebase is now set by av_codec_set_pkt_timebase. If some demuxer set AVStream.time_base directly, it need to be fixed. There is a warning to detect it.	13 years ago
Nicolas George	0fe8acf2d6	ffmpeg: add -(no)stdin option. Allows to disable interaction from standard input. Useful, for example, if ffmpeg is in the background process group. Roughly the same result can be achieved with "ffmpeg ... < /dev/null" but it requires a shell.	13 years ago
Nicolas George	52ab418588	ffmpeg: invert using_stdin and rename accordingly. There are other reasons not to use stdin than having it as an input.	13 years ago
Michael Niedermayer	dece4f4693	ffmpeg: revert `3ba90d9` (cosmetics to reduce difference to qatar by about 90 lines) This commit caused Ticket1490 (Infinity loop / lock in export image) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	5dba4cbc2f	ffmpeg: fix streamcopy of some mp3 in avi Fixes Ticket1432 Thanks-to: Mike Scheutzow <mike.scheutzow@alcatel-lucent.com> for some of the bug analysis Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	7b521c52c4	ffmpeg: add -progress option. It allows to send program-friendly (easy to parse) progress information to a file or an URL.	13 years ago
Michael Niedermayer	825e1e2437	ffmpeg: use pkt_pts before pkt->pts for audio This fixes the timestamp of the first packet when samples have been skiped. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	744bd8d08c	ffmpeg: set pkt_timebase Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	1cef5a0196	ffmpeg: fix type of av_log() argument Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Robert Krüger	c916af995d	add output for frame timestamps Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	5997285d3a	ffmpeg: poll filters even after -t limit. If not, frames can still arrive to the sink and accumulate. The frames past recording time will be ignored in do_*_out.	13 years ago
Nicolas George	2fc354f90d	ffmpeg: rework checks for the -t option. This commit is based on libav's implementation and makes sure to compare output timestamps together. It also reduces the differences with avconv. The changes to the test reference files are caused by an additional packet at the end, the timestamp of the frame encoded by this packet is always strictly below the limit stated by the -t option.	13 years ago
Michael Niedermayer	df3a96c497	ffmpeg: Add sanity check on frame duplication This prevents long loops and OOM in case of damaged timestamps in some cases Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	be24f85176	ffmpeg: re-set frame_size after filter graph reset. The filter contexts are completely cleared, so the frame size can not be kept.	13 years ago
Nicolas George	6f5e7e8690	ffmpeg: use the more powerful version of abuffersink.	13 years ago
Nicolas George	20a8dca57f	ffmpeg: fix parsing of -force_key_frames option. Identical to commit `4f6a1c9` by Reimar Döffinger, that was lost after the merge of `19ad567`.	13 years ago
Clément Bœsch	f926d91611	ffmpeg: fix a memleak in subtitles decoding.	13 years ago
Nicolas George	8069db8633	ffmpeg: warn that -t does not work with -filter_complex.	13 years ago
Nicolas George	2c793b8501	ffmpeg: warn when -t is used for inputs. Using -t on an input already have surprising results. Furthermore, using it on an input or an output makes a real difference if there are speed-altering filters. Implementing -t for inputs will probably result in some behavour changes.	13 years ago
Michael Niedermayer	e377208d43	ffmpeg: dont copy creation_time as the destination file is not created at that time Fixes Ticket1439 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Stefano Sabatini	43583fb85c	lavfi/avcodec: deprecate avfilter_fill_frame_from_*_buffer_ref API Deprecate functions: avfilter_fill_frame_from_buffer_ref avfilter_fill_frame_from_audio_buffer_ref avfilter_fill_frame_from_video_buffer_ref and schedule to drop them at the next API major bump. The function avfilter_copy_buf_props() should be used instead.	13 years ago

Clément Bœsch	492cc9bcc4	ffmpeg: remove unused buffer_size in InputFile.	13 years ago
Michael Niedermayer	2fa5d8f234	ffmpeg: print swr options in --help too Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	8c3514647e	ffmpeg.c: count subtitles in total size. This avoids the "Output file is empty" warning with subtitles-only files.	13 years ago
Michael Niedermayer	9ec5e956a2	ffmpeg: disable threading on mingw, it doesnt work due to dependance on internal code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	eae983f4ff	ffmpeg: fix fate breakage introduced by key=value buffersrc args. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	6fef82f22d	ffmpeg: with filter_complex, avoid random in<->out mapping. With complex filters, an output can come from any input, or several inputs, including inputs of a different type. Copying the codec parameters from the first input with the same type does not make any sense. This does not change anything for simple 1->1 filters, as source_index is set in that case.	13 years ago
Nicolas George	fbaa8fe6c6	ffmpeg: init icodec. With complex filter graphs, it can end up accessed without having been set.	13 years ago
Nicolas George	8362d734a3	ffmpeg: use the frame rate computed by lavfi. This frame rate is more reliable than the one copied from the input stream, so it is used in priority.	13 years ago
Nicolas George	5f281e94ba	ffmpeg: add frame rate to the buffersrc arguments. The arguments now use the key=value syntax.	13 years ago
Mike Scheutzow	1be7bfdd2b	ffmpeg.c: fix erroneous "Output file is empty" message. This message is printed whenever the RAWVIDEO codec is used, whether the output file contains any frames or not. Test command: ./ffmpeg -i infile.y4m outfile.y4m Signed-off-by: Mike Scheutzow <mjs973@optonline.net> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Nicolas George	25e87fc5f6	ffmpeg: move keyboard interaction in a function. It makes the transcode loop easier to read (30% less code) and the differences with avconv easier to spot.	13 years ago
Philip Langdale	92c065f93f	ffmpeg: Set duration on encoded subtitle packets. Currently, we don't set the duration on the packet of a newly encoded subtitle. This information may be required by the muxer. Signed-off-by: Philip Langdale <philipl@overt.org> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Reimar Döffinger	93147daf59	ffmpeg: avoid a confusing and easy to break if(). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Clément Bœsch	df03ae8dd8	ffmpeg: remove two unused variables.	13 years ago
