#4076: Poor performance when using unsharp filter on multiple outputs -------------------------------------+------------------------------------- Reporter: speaker219 | Type: defect Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: When using FFmpeg to encode two seperate video outputs from a single video source, performance drops significantly when using the "unsharp" video filter on BOTH outputs. If only used on one of the two outputs, performance appears normal. This is a problem particularly when using a DirectShow source, since the real-time buffer will almost immediately fill and cause dropped frames/out of sync audio making it impossible to stream from a live video source. First sample, showing the issue, notice the poor fps (input framerate is 59.94 fps) and real-time buffer errors causing frame drops, CPU usage is 40% or lower. {{{ cmd> ffmpeg -rtbufsize 902000k -f dshow -r 60000/1001 -video_size 1280x720 -pixel_format uyvy422 -i video="Decklink Video Capture":audio="Decklink Audio Capture" -vcodec libx264 -vf "unsharp=5:5:0.2:5:5:0.0" -preset medium -profile main -maxrate 1600k -bufsize 2000k -s 960x540 -pix_fmt yuv420p -acodec aac -strict -2 -ab 96k -ar 44100 -af "volume=3" -f flv -y "hd.flv" -vcodec libx264 -vf "unsharp=5:5:0.2:5:5:0.0,fps=fps=30" -preset medium -profile main -maxrate 900k -bufsize 2000k -s 854x480 -pix_fmt yuv420p -acodec aac -strict -2 -ab 96k -ar 44100 -af "volume=3" -f flv -y "sd.flv" ffmpeg version N-66809-g20df026 Copyright (c) 2000-2014 the FFmpeg developers built on Oct 11 2014 23:42:02 with gcc 4.9.1 (GCC) configuration: --enable-gpl --enable-version3 --disable-w32threads --enable-avisynth --enable-bzlib --enable-fontconfig --enable-frei0r --enable-gnutls --enable-iconv --enable-li bass --enable-libbluray --enable-libbs2b --enable-libcaca --enable- libfreetype --enable-libgme --enable-libgsm --enable-libilbc --enable- libmodplug --enable-libmp3lame --enable-lib opencore-amrnb --enable-libopencore-amrwb --enable-libopenjpeg --enable- libopus --enable-librtmp --enable-libschroedinger --enable-libsoxr --enable-libspeex --enable-libtheora --en able-libtwolame --enable-libvidstab --enable-libvo-aacenc --enable-libvo- amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable- libwebp --enable-libx264 --enable- libx265 --enable-libxavs --enable-libxvid --enable-zlib libavutil 54. 10.100 / 54. 10.100 libavcodec 56. 4.101 / 56. 4.101 libavformat 56. 9.100 / 56. 9.100 libavdevice 56. 1.100 / 56. 1.100 libavfilter 5. 1.103 / 5. 1.103 libswscale 3. 1.101 / 3. 1.101 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 1.100 / 53. 1.100 Guessed Channel Layout for Input Stream #0.1 : stereo Input #0, dshow, from 'video=Decklink Video Capture:audio=Decklink Audio Capture': Duration: N/A, start: 1799667.924000, bitrate: 1536 kb/s Stream #0:0: Video: rawvideo (HDYC / 0x43594448), uyvy422(tv), 1280x720, 59.94 tbr, 10000k tbn, 59.94 tbc Stream #0:1: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 kb/s Please use -profile:a or -profile:v, -profile is ambiguous Last message repeated 1 times [libx264 @ 0000000002b451c0] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 AVX [libx264 @ 0000000002b451c0] profile Main, level 3.2 [libx264 @ 0000000002b451c0] 264 -

If ffmpeg could convert to 32bit directly, there wouldn't be the need to do two conversion steps, 10 ->16->32 and native high precision video support would be much easier to implement! -- Ticket URL: <https://trac.ffmpeg.org/ticket/3657> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4374(avformat:new): Add support for ZIP archive file format protocol

#4374: Add support for ZIP archive file format protocol -------------------------------------+------------------------------------- Reporter: t.rapp | Type: Status: new | enhancement Component: avformat | Priority: wish Keywords: protocol, | Version: zip | unspecified Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+------------------------------------- When exchanging PNG/JPEG/DPX image sequences between computer stations it is easier to handle them within some archive format (uncompressed ZIP). It would be great if FFmpeg could read the files directly from the ZIP archive using a "zip://" protocol provider. Example: {{{ % ffmpeg -f image2 -i "zip://MyImages.zip/img_%06d.png" -r 25 output.mov }}} Sidenote: I also looked at using TAR for storing image sequences but as it doesn't have a file index table it has bad performance when requesting individual files from the archive. -- Ticket URL: <https://trac.ffmpeg.org/ticket/4374> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
