#6525(ffmpeg:new): Still image file format codecs are tricky to filter out of -codecs output

#6525: Still image file format codecs are tricky to filter out of -codecs output -------------------------------------+------------------------------------- Reporter: tangent | Type: Status: new | enhancement Component: ffmpeg | Priority: normal Keywords: codecs, | Version: 3.2.4 help, output | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I am interested in constructing a short command that reliably filters `ffmpeg -codecs` output to show only the list of lossless video encoders. So far, I have come up with this: {{{ $ ffmpeg -codecs 2> /dev/null | grep '^..EV..S ' | grep -Ev 'image|bitmap' }}} The second `grep` command filters out a bunch of codecs I'm not interested in like `bmp` and `pcx` because they are not "video" codecs in the way I understand the term. There is something of a gray area here, which I will deal with below. I propose that these encoders have their `V` tag in the `DEVILS` scheme replaced by either `I` or `M`: * `I` means an "image" codec, and implies that you can only encode one frame at a time with this codec, and that each frame will have a separate image header. I believe `bmp` is in this class, for example. To make a single-file movie with this encoder, you must put it into a container like AVI, MKV, or MPEG-TS. I propose that a still image file format like `jpeg-ls` keeps its `V` tag because it is often used within an A/V container format: `avi` + `jpeg-ls` = Lossless MJPEG, so `jpeg-ls` is a "video" codec to me. I'm not aware of anyone using `avi` + `bmp`, by contrast. A thought experiment you can use to decide this issue is to ask whether you are likely to find this encoder used as the argument to an `-f` flag or a `-c:v` flag. We expect `bmp` to be used with `-f` for a "pile of frames" output, but `jpeg-ls` to be used with `-c:v` and some container format with `-f` to produce a single-file movie. * `M` means a format like `gif` or `apng` that allows multiple frames with timing information per file, so that you don't need the container if you don't need associated audio or other streams. If that idea is rejected, at least give some other way to reliably filter these codecs out of the `ffmpeg -codecs` output. I'd like to see you settle on either `bitmap` or `image` and apply that term uniformly to all of the still image file formats I'm talking about here. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6525> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#6627(avformat:new): av_read_frame got incorrect packet after av_seek_frame

#6627: av_read_frame got incorrect packet after av_seek_frame -------------------------------------+------------------------------------- Reporter: sorayuki | Type: defect Status: new | Priority: normal Component: avformat | Version: git- Keywords: mp4, | master demuxer | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- I'm writing a C program to use avformat to demux the attached mp4 file and feed audio track to decoder. I found avformat read packet in incorrect size after seek to begining, and decoder refused to decode that packet. How to reproduce: windows 10 x64, visual studio 2013, linked with nightly build 20170827-ef0c6d9-win32 (32bit) from https://ffmpeg.zeranoe.com/builds/ I use av_read_frame to read packet from video file, and feed the packet of audio track through avcodec_send_packet to decoder, then receive frame by avcodec_receive_frame. After decoding finished, I use av_seek_frame to rewind and read the file again. The program's output should explain the issue. attachments are the program and sample video file. -- Ticket URL: <https://trac.ffmpeg.org/ticket/6627> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#6540(avfilter:new): Atempo filter cuts off data at the end

#6540: Atempo filter cuts off data at the end ----------------------------------+---------------------------------- Reporter: asdamos | Type: defect Status: new | Priority: normal Component: avfilter | Version: 3.2.4 Keywords: atempo | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+---------------------------------- When using atempo filter it cuts off sound data at the end of file. I was also using atempo filter from C API in similar way to [https://www.ffmpeg.org/doxygen/trunk/filter_audio_8c-example.html] I noticed that, when I pushed frame to filter graph, I had to push few more frames before I could get frame number one from filter graph. So at the end of filtering, I did not get all the frames I pushed to filter graph. Following command should produce 1 second file but produces 0.97 second file. {{{ ./ffmpeg -i one-second-file.wav -filter:a "atempo=1.0" -vn output.wavffmpeg version N-86695-g0a24d7c Copyright (c) 2000-2017 the FFmpeg developers built with gcc 4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.3) configuration: --prefix=/home/user/ffmpeg_build --pkg-config- flags=--static --extra-cflags=-I/home/user/ffmpeg_build/include --extra- ldflags=-L/home/user/ffmpeg_build/lib --bindir=/home/user/bin --enable- nonfree libavutil 55. 67.100 / 55. 67.100 libavcodec 57.100.103 / 57.100.103 libavformat 57. 75.100 / 57. 75.100 libavdevice 57. 7.100 / 57. 7.100 libavfilter 6. 94.100 / 6. 94.100 libswscale 4. 7.101 / 4. 7.101 libswresample 2. 8.100 / 2. 8.100 Guessed Channel Layout for Input Stream #0.0 : mono Input #0, wav, from 'one-second-file.wav': Duration: 00:00:01.00, bitrate: 705 kb/s Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, mono, s16, 705 kb/s Stream mapping: Stream #0:0 -> #0:0 (pcm_s16le (native) -> pcm_s16le (native)) Press [q] to stop, [?] for help Output #0, wav, to 'output.wav': Metadata: ISFT : Lavf57.75.100 Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, mono, s16, 705 kb/s Metadata: encoder : Lavc57.100.103 pcm_s16le size= 84kB time=00:00:00.97 bitrate= 706.2kbits/s speed=6.55x video:0kB audio:84kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.090681% }}} Following command should produce 2 seconds file but produces 1.92 seconds file. {{{ ./ffmpeg -i one-second-file.wav -filter:a "atempo=0.5" -vn output.wav ffmpeg version N-86695-g0a24d7c Copyright (c) 2000-2017 the FFmpeg developers built with gcc 4.8 (Ubuntu 4.8.4-2ubuntu1~14.04.3) configuration: --prefix=/home/user/ffmpeg_build --pkg-config- flags=--static --extra-cflags=-I/home/user/ffmpeg_build/include --extra- ldflags=-L/home/user/ffmpeg_build/lib --bindir=/home/user/bin --enable- nonfree libavutil 55. 67.100 / 55. 67.100 libavcodec 57.100.103 / 57.100.103 libavformat 57. 75.100 / 57. 75.100 libavdevice 57. 7.100 / 57. 7.100 libavfilter 6. 94.100 / 6. 94.100 libswscale 4. 7.101 / 4. 7.101 libswresample 2. 8.100 / 2. 8.100 Guessed Channel Layout for Input Stream #0.0 : mono Input #0, wav, from 'one-second-file.wav': Duration: 00:00:01.00, bitrate: 705 kb/s Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, mono, s16, 705 kb/s Stream mapping: Stream #0:0 -> #0:0 (pcm_s16le (native) -> pcm_s16le (native)) Press [q] to stop, [?] for help Output #0, wav, to 'output.wav': Metadata: ISFT : Lavf57.75.100 Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 44100 Hz, mono, s16, 705 kb/s Metadata: encoder : Lavc57.100.103 pcm_s16le size= 166kB time=00:00:01.92 bitrate= 705.9kbits/s speed= 282x video:0kB audio:166kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.045887% }}} -- Ticket URL: <https://trac.ffmpeg.org/ticket/6540> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
