Preserving alpha when re-encoding VP8/VP9 WebM in FFmpeg without specifying input codec - mstyura Newest 'ffmpeg' Questions - Stack Overflow

I'm trying to understand why re-encoding a VP8 or VP9 WebM with alpha channel produces black pixels instead of preserving transparency. I simplified the problem to re-encoding VP8 with alpha to VP9 with alpha: ffmpeg -i video-vp8-with-alpha.webm -c:v libvpx-vp9 video-vp8-with-alpha-bad.webm The output loses the alpha channel. ffprobe shows: Input #0, matroska,webm, from 'video-vp8-with-alpha-bad.webm': Metadata: ENCODER : Lavf62.1.103 Duration: 00:00:03.07, start: 0.017000, bitrate: 152 kb/s Stream #0:0: Video: vp9 (Profile 0), (...) -- 0828a3b636, BtbN/FFmpeg-Builds

GStreamer vs FFmpeg [closed] - user1129474 Newest 'ffmpeg' Questions - Stack Overflow

I'm trying to record a Video with the OpenCV Framework and would like to save it into an Matroska(mkv) Container together with some additional data streams. First I thought using FFmpeg is the way to go. But while looking into the OpenCV Source code and searching on the web I found GStreamer. Because the documentation in GStreamer is much better than the FFmpeg documentation I would prefer using this Framework. In my understanding GStreamer is primarily used for Streaming, but could also recode and mux video data. Is there any disadvantage when using GStreamer (...)

Hikvision NVR video conversion ffmpeg [closed] - astralmaster Newest 'ffmpeg' Questions - Stack Overflow

I have a Hikvision NVR that stores security camera footage that I need to display on a website. I know that Hikvision uses proprietary H.264 codec that makes it impossible to play (coherently) in popular video players, like VLC, unless you install that codec everywhere you play it. My plan was to transcode the video using ffmpeg to regular H.264 codec and AAC for audio but the produced file has the same issues as the original - no audio when playing and very disruptive video.

how to upscale video max dimensions which fit within target size using ffmpeg? [closed] - bguiz Newest 'ffmpeg' Questions - Stack Overflow

I'm using the following ffmpeg command to crop off the top N pixels from the input video, and replace it with a black padding: INVID="" OUTVID="" ffmpeg \\ -y \\ -i "$INVID" \\ -vf "crop=iw:ih-30:0:30,pad=iw:ih:0:0:black" \\ "$OUTVID" ffprobe "$OUTVID" In the ffprobe output, I can see the dimensions of the output video. However, the dimensions of the output video is entirely dependent on the dimensions of input video. In some cases, my input video are in odd sizes, and I wish to scale them up to a particular set of (...)

Converting mkv files to mp4 with ffmpeg-python [closed] - myth0s Newest 'ffmpeg' Questions - Stack Overflow

I have a lot of .mkv files that I'm trying to convert to .mp4, so I decided to try and program a solution in python. After a few hours, trying to figure out how to copy the subfolders too, I gave up on it and decided to stick with converting individual subfolders, and then copying them over to another directory. I've made a simple script, that should convert .mkv files that are in the same folder as the script. However, I keep getting this error: FileNotFoundError: [WinError 2] The system cannot find the file specified Here's my code: import (...)

avfilter/setpts: also preserve duration when not stripping fps - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/setpts: also preserve duration when not stripping fps It makes sense to treat the presence of a frame duration and the presence of frame rate metadata identically - because both convey effectively the same amount of information. In f121d95 and fa110c3 respectively, this information was stripped by default, originally to work-around bugs when changing the PTS information of a stream being fed to some encoders. (See https://trac.ffmpeg.org/ticket/10886) Later, commit 959b799c restored the ability to preserve the frame rate medatata via the `strip_fps` option, but this option did (...)

avcodec/atrac3: fix inconsistent band num calculation - Daniil Cherednik git.videolan.org Git - ffmpeg.git/rss log

avcodec/atrac3: fix inconsistent band num calculation 'decode_spectrum' reads 5 bits from bitstream to get number of encoded subbands – so 31 means all 32 subbands are encoded. This value also is used to determinate the number of used band in the hybrid filterbank. 'subband_tab' array contains 33 values of MDCT spec line positions started from 0 line and used to map subband number in to the range of mdct lines. Since the subband_num returned by decode_spectrum actually is number – 1 and subband_tab started from 0 we need to add 1 to make num_bands calculation correct. [DH] (...)

avfilter/vf_libplacebo: fix possible segfault when frame mixing - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

avfilter/vf_libplacebo: fix possible segfault when frame mixing pl_frame_mix_current() will return NULL if all frames are in the future, but when libplacebo is using a frame mixer with a radius greater than 1, future frames are expected to already be partially renderered. Instead, use pl_frame_mix_nearest(), which is guaranteed to give us a valid frame for any nonempty frame mix. Fixes: 3091bca3edb339a4d2ec8c64e52fa7e67a7d5005 [DH] libavfilter/vf_libplacebo.c

avcodec/mjpegdec: decode only SOF fields when finding stream info When called from avformat_find_stream_info(), we are only interested in decoding SOF fields.

Manually generate "empty" h264 p-frame - leavittx Newest 'ffmpeg' Questions - Stack Overflow

Let's call a p-frame frame empty if it doesn't change any pixels in the currently decoded video (i.e. no motion vectors, nothing). What I need is to be able to manually insert empty p-frame into the video stream on request (need to send frames to the streaming client with a constant framerate, however the frame source on the streaming server can supply frames with a different/lower one). So I need to be able to correctly form the byte sequence which represents the empty p-frame for the current resolution (I wonder which other parameters could be (...)

avutil/avassert: always implement av_assume with av_unreachable One of the design goals of this macro is the ability to support static inline predicate functions. Which is emitting warning in clang that a function may have side-effects and the condition will be ignored. MSVC doesn't emit warning, but also ignore predicate in such cases. Instead of using assume builtins, implement it using unreachable. Which solves this case for MSVC and Clang.

How to append dummy frames to FFmpeg pipe after EOF to prevent Shaka Packager from stopping (LL-HLS/LL-DASH)? [closed] - Arjit Newest 'ffmpeg' Questions - Stack Overflow

I am working on a live streaming pipeline where I pipe FFmpeg into Shaka Packager to generate LL-HLS and LL-DASH output from an RTMP stream. Scenario: FFmpeg receives the RTMP stream and pipes the output to Shaka Packager. When the RTMP publisher stops streaming, FFmpeg naturally ends, sending an EOF (end-of-file) to the pipe. This causes Shaka Packager to stop processing, as it closes its read stream on EOF.

configure: use proper Windows-style static library naming On Windows, static libraries are typically named with a .lib extension. An exception to this is MinGW targets, which are treated as a distinct target-os. Using Windows-style naming allows `clang` to be used as the linker driver, instead of invoking link or lld-link directly. The latter approach requires manually specifying standard libraries when compiling with `clang` rather than `clang-cl`, and manually specifying standard libraries may be error-prone or incomplete.

configure: require at least OpenSSL 1.1.1 (LTS) Commit f256487cd8f29f24036efa5d91a84a26b048861a bumped requirement to 1.1.0 for OPENSSL_init_ssl. Bump this again to 1.1.1, because it was an LTS version. Although it has no mainline support anymore, it still has paid/premium support. 1.1.0 has no support at all. Motivated for use of BIO_read_ex() for next commits. Signed-off-by: Kacper Michajłow <kasper93ⓐgmail.com> [DH] Changelog [DH] configure

swscale/alphablend: don't overread alpha plane on subsampled odd size - Niklas Haas git.videolan.org Git - ffmpeg.git/rss log

swscale/alphablend: don't overread alpha plane on subsampled odd size This function overreads the input plane for odd dimensions, because the chroma plane is always rounded up, which means (xy << subsample) + 1 exceeds the actual alpha plane size. To verify: valgrind ffmpeg -pix_fmt yuva420p -f lavfi -i color -vf \\ "scale=1x1,format=yuva420p,scale=alphablend=uniform_color,format=yuv420p \\ -vframes 1 -f null - Fixes: https://trac.ffmpeg.org/ticket/11692 [DH] (...)

How can I generate a metadata.mov file for higher-resolution Live Photos (e.g. 1440x2560)? - brijesh patel Newest 'ffmpeg' Questions - Stack Overflow

I'm generating Live Photos programmatically for use as wallpapers on iOS. I'm using a known metadata.mov file bundled with the app (likely extracted from a working Live Photo with resolution 1080x1920). This setup works fine when I use a video of the same resolution. I'm using this open-source library to handle the video-to-LivePhoto conversion: https://github.com/TouSC/Video2LivePhoto However, when I try using a higher-resolution video (e.g. 2560x1440) to avoid black bars on high-resolution devices (like iPhone 14 Pro Max), the Photos app shows the Live (...) -- https://github.com/TouSC/Video2LivePhoto
