#3623(undetermined:new): Mixed results writing M4A metadata

For example these commands {{{ ffmpeg -i superuser.mp4 -c copy good.aac ffmpeg -i good.aac -c copy -bsf aac_adtstoasc -metadata title=Confetti \ -movflags faststart good.m4a }}} Will generate an M4A file that plays correctly with metadata that is recognized. However this command {{{ ffmpeg -i superuser.mp4 -c copy -vn -movflags faststart \ -metadata title=Confetti bad.m4a }}} Generates a file that plays correctly, but my player does not recognize the metadata. Note I also tried adding `-bsf aac_adtstoasc` to the bad command to no avail. How can I tweak the second command to get it working?

#3586(avcodec:new): [discrepancy with libav] avcodec_encode_video2 merges packet side data with the packet body
by FFmpeg 10 Apr '21

#3586: [discrepancy with libav] avcodec_encode_video2 merges packet side data with the packet body -------------------------------------+------------------------------------- Reporter: Lastique | Type: defect Status: new | Priority: normal Component: avcodec | Version: 2.2.1 Keywords: libav | Blocked By: avcodec_encode_video2 avpacket | Reproduced by developer: 0 av_packet_merge_side_data | Blocking: | Analyzed by developer: 0 | -------------------------------------+------------------------------------- We have an application which uses ffmpeg to encode video in h263. The application requests h263_mb_info side data by setting the "mb_info" option on the encoder context: {{{ av_opt_set_int(av_ctx, "mb_info", 1400, AV_OPT_SEARCH_CHILDREN) }}} Later we call avcodec_encode_video2() to encode frames. The problem is that ffmpeg avcodec_encode_video2() returns AVPackets with the encoded frame and some amount of junk at the end. From the source code I can see that the junk is actually the encoded side data (mb_info) appended to the h263 packet by av_packet_merge_side_data() which is called by avcodec_encode_video2(). This appended side data prevents the packets from being decoded by ffmpeg 2.2.1 (I tried both decoding through the API and ffplay). Decoding results in many messages such as: {{{ slice end not reached but screenspace end (399 left 019CE3, score= -7) concealing 88 DC, 88 AC, 88 MV errors in P frame }}} and corrupted image. This is also different from libav behavior. At least 9.x and 10.x versions don't merge side data into the packet body, and when using libav we don't have the decoding problem. Looking at the libavcodec code I don't really understand why the call to av_packet_merge_side_data() is needed. Side data, at least mb_info in case of h263, is not the part of the encoded media and thus should not be part of the packet body. Since the packet size (AVPacket::size) includes the appended side data, there is no way to obtain the size of the actual media. I suspect, av_packet_split_side_data() can be used to restore the original un-merged packet, but (a) it is not documented and (b) doing av_packet_merge_side_data() and av_packet_split_side_data() is a waste of memory and CPU (note: we pre-allocate packet data buffer to optimize performance). Therefore my preferred solution would be to remove the call to av_packet_merge_side_data() from avcodec_encode_video2(). If that call cannot be removed then what is the correct way to obtain the actual media from the merged packet? -- Ticket URL: <https://trac.ffmpeg.org/ticket/3586> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#4076(undetermined:new): Poor performance when using unsharp filter on multiple outputs
by FFmpeg 14 Feb '21

#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 -

#3657: 32 Bit per Channel sws conversion ---------------------------------+--------------------------------------- Reporter: sun | Type: enhancement Status: new | Priority: wish Component: swscale | Version: unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ---------------------------------+--------------------------------------- Hello, As there are more and more Cameras able to record with more than 8 bit per pixel and there already are programs like Shotcut and Blender which support high-precision internal processing, e.g. blender is unable to handle 10-bit videos properly, because converting a 16 bit buffer from the sws yuv to rgb conversion to its internal 32bit buffer would be too slow and therefore it has to use an 8 bit buffer. 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
