Cannot set ALSA buffer size (Invalid argument) during capture

Hello! I am trying to capture audio from an ATI Wonder 600 USB adapter using ffmpeg -f alsa -ac 2 -ar 48000 -i hw:1,0 -t 10 a.wav but I receive the error [alsa @ 0x555d7c2850a0] cannot set ALSA buffer size (Invalid argument) hw:1,0: Input/output error using - ffmpeg version 3.3.4-2+b3 - alsa k4.13.0-1-amd64 - linux 4.13.0-1-amd64 Note that `arecord -l` gives: card 0: PCH [HDA Intel PCH], device 0: ALC1220 Analog [ALC1220 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 2: ALC1220 Alt Analog [ALC1220 Alt Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Em28xxAudio [Em28xx Audio], device 0: Em28xx Audio [Empia 28xx Capture] Subdevices: 1/1 Subdevice #0: subdevice #0 and I can capture audio/video without problems using the `qv4l2` test bench. Thanks! Marco

pan filter confusion
by Carles Vila 27 Nov '17

27 Nov '17

Hi I can't get my head around how the pan filter works, in theory all is clear but in practice I fail with the result. My input is a mov container with 1 ProRes stream and 1 audio stream with 12 channels. I'd like to create a small stereo H264 file with a special combination of those channels: Left channel should be ch0+ch1 mixed and Right channel = ch2+ch3. (Channels 5-11 discarded) So far I've been able to create a stereo mp4 file, but the audio is silent. Could you please have a look at what I'm doing wrong? Specifically I'm not sure what the [0:1] before the pan does, but it seems to be necessary.

If FFmpeg compatible with Windows Docker ?
by Shyam Sundar 27 Nov '17

27 Nov '17

Hi, I am trying to run FFmpeg 3.3.3 windows static binary on windows docker container, same binary which works perfectly on normal windows machine. Incase of docker, looks like the process itself is not getting launched when ffmpeg.exe command is run. I don't see any error either. Strange behavior. I was wondering if anyone has used FFmpeg on windows docker in past and whether or not this is officially supported. Thanks

Hello. I have an issue with using yadif and OpenCL (opencl with the latest git updates) in combination. Using the latest ffmpeg master built as at 2017.11.26, I'm having trouble deciphering what the error messages means and, more importantly, what to do about them.

Feature request: -number_range
by Michael Koch 26 Nov '17

26 Nov '17

The option "-start_number_range" is only used when searching for the first image of a sequence. I propose to add a new option "-number_range" that specifies the number of trials if the next image in a sequence isn't found. For example, when making a timelapse from hundreds of images, it may be necessary to exclude a few images from the sequence. But we can't simply delete these images, because ffmpeg will stop if the next image isn't found. Possible workarounds are duplicating one of the neighbor images, or renaming all subsequent images. With the proposed option ffmpeg would just skip the missing images. Thanks, Michael

Bit Depth of PNG Overlay with Alpha channel
by Pete Willis 26 Nov '17

26 Nov '17

We have a transparent PNG file with a drop shadow. The drop shadow when overlayed onto a Mov is rendering very dark. Comparing the same file in an NLE (Premiere Pro) the drop shadow opacity is showing as much lighter. I believe the problem is that the NLE is using 32bit colour depth where as FFMPEG is using 8bit colour depth. Is there a way to specify the colour depth of the overlay or the png? The param we are using is -filter_complex ‘overlay’, Input: ffmpeg -I TEST-1.mxf -i test-1.png -filter_complex 'overlay[out]' -c:v libx264 -profile high10 -map '[out]' out2.mp4 Output: ffmpeg version 3.4-tessus Copyright (c) 2000-2017 the FFmpeg developers built with Apple LLVM version 8.0.0 (clang-800.0.42.1) configuration: --cc=/usr/bin/clang --prefix=/opt/ffmpeg --extra-version=tessus --enable-avisynth --enable-fontconfig --enable-gpl --enable-libass --enable-libbluray --enable-libfreetype --enable-libgsm --enable-libmodplug --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libopus --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libtheora --enable-libvidstab --enable-libvo-amrwbenc --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxvid --enable-libzmq --enable-libzvbi --enable-version3 --pkg-config-flags=--static --disable-ffplay libavutil 55. 78.100 / 55. 78.100 libavcodec 57.107.100 / 57.107.100 libavformat 57. 83.100 / 57. 83.100 libavdevice 57. 10.100 / 57. 10.100 libavfilter 6.107.100 / 6.107.100 libswscale 4. 8.100 / 4. 8.100 libswresample 2. 9.100 / 2. 9.100 libpostproc 54. 7.100 / 54. 7.100 Guessed Channel Layout for Input Stream #0.1 : mono Guessed Channel Layout for Input Stream #0.2 : mono Guessed Channel Layout for Input Stream #0.3 : mono Guessed Channel Layout for Input Stream #0.4 : mono Input #0, mxf, from '/Users/petew/Downloads/Video/Nov - 17/IN_GAME_1ST_THvMC_2_171101_BC_TEST07.mxf': Metadata: uid : 0b60c130-c23e-11e6-9861-8cdcd4127984 generation_uid : 0b60c130-c23e-11e6-9862-8cdcd4127984 company_name : OC product_name : OCTk product_version : 2.8 product_uid : 3a4fe380-0d01-11e4-869f-3cd92b5c1dfc modification_date: 2016-12-14T20:44:01.000000Z material_package_umid: 0x060A2B340101010501010D20130000000B60C130C23E11E698488CDCD4127984 timecode : 00:00:00:00 Duration: 00:00:22.68, start: 0.000000, bitrate: 55110 kb/s Stream #0:0: Video: mpeg2video (4:2:2), yuv422p(tv, bt709, top first), 1920x1080 [SAR 1:1 DAR 16:9], 50000 kb/s, 25 fps, 25 tbr, 25 tbn, 50 tbc Metadata: file_package_umid: 0x060A2B340101010501010D20130000000B60C130C23E11E698328CDCD4127984 Stream #0:1: Audio: pcm_s24le, 48000 Hz, mono, s32 (24 bit), 1152 kb/s Metadata: file_package_umid: 0x060A2B340101010501010D20130000000B60C130C23E11E698328CDCD4127984 Stream #0:2: Audio: pcm_s24le, 48000 Hz, mono, s32 (24 bit), 1152 kb/s Metadata: file_package_umid: 0x060A2B340101010501010D20130000000B60C130C23E11E698328CDCD4127984 Stream #0:3: Audio: pcm_s24le, 48000 Hz, mono, s32 (24 bit), 1152 kb/s Metadata: file_package_umid: 0x060A2B340101010501010D20130000000B60C130C23E11E698328CDCD4127984 Stream #0:4: Audio: pcm_s24le, 48000 Hz, mono, s32 (24 bit), 1152 kb/s Metadata: file_package_umid: 0x060A2B340101010501010D20130000000B60C130C23E11E698328CDCD4127984 Input #1, png_pipe, from '/Users/petew/Downloads/Images/Nov - 17/GCCM0632000H Art Card lease hisp-1.png': Duration: N/A, bitrate: N/A Stream #1:0: Video: png, rgba(pc), 1920x1080, 25 tbr, 25 tbn, 25 tbc File '/Users/petew/Desktop/out3.mp4' already exists.
