#9764(avcodec:new): MP3 decoding errors on ARMv4 hardware
by FFmpeg 17 Aug '22

#9764: MP3 decoding errors on ARMv4 hardware -------------------------------------+------------------------------------- Reporter: David | Type: defect Fletcher | Status: new | Priority: normal Component: avcodec | Version: git- | master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: There is distortion, especially for low bitrate stations, using the FFmpeg fixed point mp3 decoder on older (ARMv4) processors. This does not occur using the same configuration in x86 or more modern/capable ARM processors. The problem can be worked around using the libmad MP3 decoder which works perfectly on the ARMv4 processor (see patch [http://ffmpeg.org/pipermail /ffmpeg-devel/2022-May/295941.html]. But this just works around the issue rather than fixing it. I spent a lot of time looking at the fixed point math routines, especially libavcodec/arm/mpegaudiodsp_fixed_armv6.S. This is the main place there's ARM6 specific code - I wrote a new version of this for AMRv4 but it didn't fix the issue. == How to reproduce: == I've made a demonstration of transcoding an MP3 radio stream and saving it to file. It is saved in the AU format (this is useful in my application, changing the output format does not solve the issue). Relevant files are in "mp3_decode_ARMv4_errors.tar.gz" uploaded to upload.ffmpeg.org. transcode_v4_ffmpeg.c - program to do the transcoding (Instructions to compile are at the top of this file. It makes use of static libraries for form a static binary. In the case of the ARMv4 hardware this is required as part of reducing binary size to get it onto the filesystem of the embedded board which has only 32MB storage, and 32MB RAM. I followed the same static route for the ARMv7 case - use of static libraries is not the issue). output_armv4t.au - output from the ARMv4 system - listenable, but poor quality output_arm7.au - output from the ARMv7 system - very good quality sound Below is debug output generated from both systems, and also the configuration used to compile the libraries. This differs between the systems as for ARM4 it's a cross-compilation on another machine, whereas for ARM7 the compiler exists on the same machine that the binary will run on. == Arm 7 implimentation: == ./transcode_v4_ffmpeg [NULL @ 0xdcd260] Opening 'http://stream.live.vc.bbcmedia.co.uk/bbc_world_service' for reading [http @ 0xdcd5c0] Setting default whitelist 'http,https,tls,rtp,tcp,udp,crypto,httpproxy,data' [tcp @ 0xdd0130] Original list of addresses: [tcp @ 0xdd0130] Address 132.185.209.55 port 80 [tcp @ 0xdd0130] Address 132.185.210.58 port 80 [tcp @ 0xdd0130] Address 132.185.209.58 port 80 [tcp @ 0xdd0130] Address 132.185.210.72 port 80 [tcp @ 0xdd0130] Interleaved list of addresses: [tcp @ 0xdd0130] Address 132.185.209.55 port 80 [tcp @ 0xdd0130] Address 132.185.210.58 port 80 [tcp @ 0xdd0130] Address 132.185.209.58 port 80 [tcp @ 0xdd0130] Address 132.185.210.72 port 80 [tcp @ 0xdd0130] Starting connection attempt to 132.185.209.55 port 80 [tcp @ 0xdd0130] Successfully connected to 132.185.209.55 port 80 [http @ 0xdcd5c0] request: GET /bbc_world_service HTTP/1.1 User-Agent: Lavf/LIBAVFORMAT_VERSION Accept: */* Range: bytes=0- Connection: close Host: stream.live.vc.bbcmedia.co.uk Icy-MetaData: 1 [http @ 0xdcd5c0] Metadata update for StreamTitle: BBC World Service Online [mp3 @ 0xdcd260] Format mp3 probed with size=65536 and score=50 [mp3 @ 0xdcd260] Skipping 28 bytes of junk at 0.

ARMv4 has no floating point CPU, whereas ARM7 does - not both were configured to use the fixed point mp3 decoder (from reading the code this is a default unless you specifically ask for the floating point version). The cross-compilation environment is ancient (a consequence of the target system, the Reciva Radio platform being ~16-17 years old). But compilation runs without errors other than lines 123 of libavutil/error.c which throw an error about "wrong type of argument to unary minus" - this can be resolved by commenting out the offending line and making the function return -1. This has no effect on the primary mp3 decoding issue. Multiple other libraries compiled using the same cross-compilation system and also making machine code optimisations are working fine (wolfSSL, libmad, fdk- aac-free(libfdk-aac). There could be a compiler issue, but I think it's more likely something about the fixed point math routines used in FFmpeg. Working with version 5.0.1 I got this issue, but all tests were repeated using git-master. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9764> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker

#6451: ffmpeg not able to decrypt mp4 fragment files ----------------------------------+-------------------------------------- Reporter: jero3000 | Type: defect Status: new | Priority: critical Component: avformat | Version: git-master Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | ----------------------------------+-------------------------------------- I am trying to decrypt a mp4 fragment file with ffmpeg. The mp4 fragment file (attached) has the first three segments unencrypted ('senc' box is not present in the first three segments). Ffmpeg only parses the first 'senc' box and assumes that has the enough information to decrypt the entire content. When the first 'senc' box (owned by the fourth segment) is parsed, the subsample info is correctly added to the "cenc" structure (MOVStreamContext), but when the reader tries to get the first packet from the forth segment, it assumes that the current segment is the forth encypted, however it is just first one. As a result, the offsets accessing the "cenc" structure are incorrect and these errors are showed in the output: {{{ [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f82c00015a0] auxiliary info offset 4800 greater than auxiliary info size 1600 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f82c00015a0] auxiliary info offset 4816 greater than auxiliary info size 1600 [mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f82c00015a0] auxiliary info offset 4832 greater than auxiliary info size 1600 ... }}} How to reproduce: 1.

#9577(ffmpeg:new): Wrong segments encoding to MXF XDCAM HD422
by FFmpeg 16 Aug '22

#9577: Wrong segments encoding to MXF XDCAM HD422 -------------------------------------+------------------------------------- Reporter: Michel | Type: defect Status: new | Priority: normal Component: ffmpeg | Version: Keywords: segment | unspecified mpeg2video | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- Summary of the bug: Hi all, I'm trying to encode a feed from a Decklink card to MXF XDCAM HD422 by segment. The command line I use works fine, but the resulting segments are incorrect. Segments after the first segment always have the first three frames duplicated with the third frame. !!! Also, not always, in the transition from first segment to second segment there is a missing frame. This results in a one-frame delayed audio over the video in the post-first segments.

#9872(undetermined:new): WebP vs PNG alpha

#9872: WebP vs PNG alpha -------------------------------------+------------------------------------- Reporter: Jozef | Type: defect Chutka | Status: new | Priority: normal Component: | Version: undetermined | unspecified Keywords: scale , png | Blocked By: , webp , alpha | Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- using ffmpeg version 2022-07-31-git-1368b5a725-full_build-www.gyan.dev Attached x.png and x.webp (webp created from png) have transparent background covered by white X shape. For some reason FFmpeg scale filter treats the x.png and x.webp differently. Applying scale filter on the x.webp, causes the output video alpha around the X shape to be premultiplied and so renders with ugly edges. Following commands, esp. out-webp-scale.png output demonstrates the issue: ``` ffmpeg -filter_complex "color=white:200x200[b];movie=x.png,[b]overlay" -y out-png.png ffmpeg -filter_complex "color=white:200x200[b];movie=x.png,scale=200:200,[b]overlay" -y out-png- scale.png ffmpeg -filter_complex "color=white:200x200[b];movie=x.webp,[b]overlay" -y out-webp.png ffmpeg -filter_complex "color=white:200x200[b];movie=x.webp,scale=200:200,[b]overlay" -y out- webp-scale.png ``` I tried all possible scale filter flags, and also format changing (before and after scale) but no luck to achieve the same result. I am able to un- premultipy the problematic one with `unpremultiply` filter but I would like to avoid it. I wonder if this is a bug or an expected behaviour. -- Ticket URL: <https://trac.ffmpeg.org/ticket/9872> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
