Stream #0:1 -> #0:1 (aac (native) -> pcm_s16le (native))I have a set of MP4 files all of them play with VLC on my Ubuntu box.
Stream #0:0 -> #0:0 (mpeg4 (native) -> wrapped_avframe (native)) Could not find codec parameters for stream 0 (Video: mpeg4 (Simple Profile) (mp4v / 0x7634706D), yuv420p, 45242 kb/s): unspecified sizeĬonsider increasing the value for the 'analyzeduration' (0) and 'probesize' (5000000) options How is it that ffmpeg module in VLC decodes the video properly but ffmpeg itself doesn't? Any idea how to convert this video to h264/h265?įull log without error: $ ffmpeg -i SomeFile_01_31_17_08_21.mp4 -f null -įfmpeg version git-fab00b0 Copyright (c) 2000-2020 the FFmpeg developersĬonfiguration: -enable-gpl -enable-version3 -enable-sdl2 -enable-fontconfig -enable-gnutls -enable-iconv -enable-libass -enable-libdav1d -enable-libbluray -enable-libfreetype -enable-libmp3lame -enable-libopencore-amrnb -enable-libopencore-amrwb -enable-libopenjpeg -enable-libopus -enable-libshine -enable-libsnappy -enable-libsoxr -enable-libsrt -enable-libtheora -enable-libtwolame -enable-libvpx -enable-libwavpack -enable-libwebp -enable-libx264 -enable-libx265 -enable-libxml2 -enable-libzimg -enable-lzma -enable-zlib -enable-gmp -enable-libvidstab -enable-libvmaf -enable-libvorbis -enable-libvo-amrwbenc -enable-libmysofa -enable-libspeex -enable-libxvid -enable-libaom -enable-libgsm -enable-librav1e -disable-w32threads -enable-libmfx -enable-ffnvcodec -enable-cuda-llvm -enable-cuvid -enable-d3d11va -enable-nvenc -enable-nvdec -enable-dxva2 -enable-avisynth -enable-libopenmpt -enable-amf This question suggests that this is a standard mp4 codec supported by ffmpeg module in VLC. Too many packets buffered for output stream 0:1.įfmpeg -codecs doesn't show it as one of the codecs. Context scratch buffers could not be allocated due to unknown size.
video_get_buffer: image parameters invalid However, when trying to read this stream with ffmpeg, it reports the following errors: $ ffmpeg -v error -i Somefile_01_31_17_08_21.mp4 -f null. The codec reported by VLC is: Codec: MPEG-4 Video (mp4v)Īdditional info that MediaInfo reports: Codec ID: mp4v-20 I have problem with ffmpeg properly recognizing a video encoded with Microsoft Fast Mpeg 4v2 codec.
